Link-Belt® and Rexnord® Roller Chain The best. By choice.

A Many diverse elements go into each link of roller chain. Engineering ability. Material quality. Manufacturing technologies. Worker skills. And, every chain manufacturer has the same opportunity to select the elements which constitute this product. Rexnord has chosen to produce only the best. Doing that requires the highest quality materials, designed and improved by the best engineering minds, and manufactured by the industry’s most advanced and precise processes. It requires never standing still, but constantly striving to improve ... and backing that effort with the financial commitment a continuing investment in quality requires. It requires insisting on tough internal quality standards that exceed even the demanding minimums required by the American National Standards Institute. It requires staying constantly in touch with individual needs for roller chain that will deliver long life and reliable performance, even in the most limited space and under the harshest of hostile environments.

Superior quality support for superior quality products No matter how good it is, any roller chain falls short of being the best if it isn’t available when and where it’s needed. So a wide network of stock-carrying distributors maintain immediately available quantities of Link-Belt® and Rexnord® roller chain. To give you the best, when and where you need it. In turn, vast Link-Belt® and Rexnord® warehouse inventories support distributor stocks, allowing for overnight delivery in many cases. Further supplementing these efforts, strategically located Sales Offices and Service Centers provide for direct, in-depth consultation. Each is staffed with knowledgeable customer service representatives and sales specialists, who are able to aid in matters from the simplest application questions to developing complete power transmission systems for specific applications.

And it requires building on more than a century of experience and tradition, to provide products which deliver an extra edge in performance. Time after time after time. All of these factors add up to your assurance that only the highest quality roller chain bears the familiar Link-Belt® and Rexnord® symbol on its sidebars. It’s the best by choice.

Link-Belt® and Rexnord® Roller Chain Features and Benefits

A Features Link-Belt®

Benefits Rexnord®

Link-Belt®

Rexnord®

Holes quality is critical to maintaining the overall fatigue strength of the chain. Precision pierced holes

This results in higher pin and bushing push outs and improves fatigue strength. Extends chain life. Critical for performance both in wear conditions and fatigue life.

Precision-controlled heat treatment process Consistent, high quality. Ensures precision components, tight tolerances, and uniformity. Automatically assembled & preloaded Easy installation and alignment. Pre-lubricant is the most important lubrication a chain undergoes. All chains are hot dipped in a special chain lubricant that penetrates chain joints. Factory pre-lubrication

Provides for minimal lubrication required at installation. Improves chain life in use or on the shelf.

Through-hardened pins (from 80 pitch and upward) Shot-peened components & Drifted sidebars (ONLY for API Certified Chains.)

A-2

Case-hardened pins

Provides maximum strength. Improves overall fatigue strength. Increased chain life.

Maximum wear life.


Link-Belt® and Rexnord® Roller Chains Drives

Standard roller chain is broadly used in power transmission applications ranging from general industrial applications to demanding oil field service to operation in such specialized areas as food processing and heavy construction equipment.

Standard roller chain/single strand

A

Single and multiple standard roller chains, available in many sizes, meet most drive requirements. Specifications are shown on pages B-1 through B-3. Double-pitch drive chains frequently prove the economical choice for slower speed drives on relatively long centers. For details, see page B-6. Modifications of these chains, developed for special operating conditions, are described below. Corrosion resistance—Standard roller chain made of stainless steel provides excellent performance in applications requiring high resistance to corrosive attack. See page B-7.

Standard roller chain/multiple strand

Double-pitch drive chain

ULTR-O-LIFETM O-ring roller chain1— Uses square cross sectional O-rings to seal in special lube while sealing out dirt, moisture and other contaminants. Available in 5/8” thru 1 1/4” pitch single pitch series. Runs on standard ANSI sprockets. See page B-8. Shock resistance—Link-Belt® SU and Rexnord® Heavy "H" series roller chain provides additional capacity to withstand intermittent shock loading. Features include improved fatigue resistance, thicker sidebars, and heat-treated pins. See page B-4.

Extra clearance—Trans-Flex® chain is designed for severe duty applications, such as in transit mixers, crawler drives, and other uses requiring delivery of full power despite recurrent sprocket misalignment. See page B-6.

Side bow roller chain1—Extra clearance chain with ability to flex and twist. Ideal for use on curved conveyors or to transmit power under misaligned sprocket conditions. Available in 3/8” to 1” single pitch. See page D-15. Block chain1—Used in light load, low speed conveyors. Consisting of block links (solid or laminated) and link plates joined by pins, all block chains are 1” pitch and vary in width of block from 3/16” to 1/2”. See page D-16. Hollow pin chain1—The truly versatile conveyor chain. Constructed with special pin links which have hollow pins assembled in the pin plates. This unique design allows easy insertion of cross rods or attachments to preassembled chain at desired spacings. Attachments can be repositioned without removing chain from conveyor. It is available in single and double-pitch with or without Carrier Rollers. Full line of standard attachments available. 33 See page D-11. REDI-LUBETM chain1—Self-lubricating, heavy walled, oil-impregnated, sintered steel bushings replace bushing and roller of standard ANSI chain. Available in single and double-pitch. Full range of standard attachments also available. See page D-9.

Conveyors

Restricted lubrication

Standard and double-pitch conveyor chains are available with a selection of attachments to accommodate slats, angles, rollers, crossroads, and other conveying devices. You’ll find details on these widely used conveyor chains and attachments on pages D-3 through D-8.

Double-pitch roller chain with large-diameter rollers combines smooth, quiet operation and long life. This modification proves particularly useful in applications requiring minimum lubrication or where conditions make lubrication difficult. See page D-6.

Conveyor chain design modifications to meet specific application requirements are described below.

SU (Super Ultimate) and H (Heavy) Series Chains

Link-Belt® SU and Rexnord® H series chains differ from standard roller chains in sidebar thickness and in pin material and heat treatment. The combination of increased sidebar thickness and high hardness alloy through hardened pins results in greater average ultimate tensile strength ratings for the SU and H series chains. The SU and H chains are capable of withstanding higher operating and intermittent shock loading without reduction of pin-bushing wear life.

B

Multiple width SU and H series chains are available. SU and H series single strand roller chains operate on standard series roller chain sprockets. However, multiple strand heavy series chains require sprockets with rows of teeth with wider spacing to accommodate the thicker chain sidebars. See page B-5.

Sprocket Tooth Profile - Heavy Series Roller Chain

Single strand heavy series roller chain can be used with ANSI standard series roller chain sprockets of corresponding pitch. However, multiple strand heavy series roller chain cannot be used with the standard series sprockets, because of the extra thickness of link plates on the heavy series. Sprockets for multiple strand heavy series roller chain must be made to order.

Link-Belt® and Rexnord® Drive Chains Double-pitch drive chains

CHAIN PITCH

Double-pitch drive chains are dimensionally identical to standard roller chains of the same strength, except for pitch length, which is “doubled”. With only one-half the number of pins, bushings , and rollers, double-pitch chains are lighter and more economical than standard roller chains and are ideal for slow and moderate speed applications, particularly when shaft centers are relatively long.

B

A

Sprockets • Sprockets for double-pitch drive chains are normally furnished with two times the number of teeth required to contact the chain. As illustrated at right, the relationship between chain pitch and roller diameter results in adequate space for a second set of teeth, which substantially increases sprocket life.

Link-Belt® and Rexnord® Drive Chains Corrosion resistant chains

Stainless Steel Chains: Stainless steel chain sideplates are manufactured from AISI Type 300 chrome nickel stainless steel, with pins, bushings and rollers manufactured from AISI Type 400 stainless steel providing a balanced combination of wear, corrosion and heat resistance adequate for most operating conditions. Where increased corrosion, wear and/or heat resistance is required, chains may be custom designed and manufactured with components made from other grades of stainless steel compatible with the specific operating conditions.

B

Plated Chains: Standard carbon steel chain, assembled from parts individually plated with nickel, zinc or chrome, can be furnished to provide improved corrosion and/or wear characteristics compared to a standard, unprotected carbon steel chain. Assembled carbon steel chains should not be plated because component failure may occur. Sprockets: Standard carbon steel sprockets may be suitable for many applications; however, sprockets can be made from a variety of corrosion-resistant materials to suit application conditions. They are manufactured to the same applicable standards and dimensions as sprockets for standard precision roller chains.

Drive Engineering

Engineering recommendations Chordal action • The rise and fall of each pitch of chain as it engages a sprocket is termed chordal action and causes repeated chain speed variations. As illustrated by chart A, chordal action and speed variation decrease as the number of teeth in the small sprocket is increased. Chordal action becomes negligible when 25 or more teeth are used and results in smoother drive operation.

Several drive selections can usually be made for a given application. Consideration of life expectancy, space, speed, cost and similar factors often suggest the better selection. Use the following recommendations as a guide when selecting roller chain drives. Horsepower ratings • The horsepower ratings listed on pages C-9 to C-35 apply directly to lubricated, single strand, standard and heavy series roller chains. Multiple strand chains are selected from the same rating tables by applying the factors in Table 2, page C-7. Stainless steel chain and other variations of standard roller chain are also selected from the rating tables by applying the appropriate material or design variation factor from Table 3, page C-7.

Quietness • Speed and horsepower usually determine chain pitch. When quietness is essential, select a smaller pitch, wider chain and a driver sprocket with at least 25 teeth. Number of teeth for large sprockets • The number of teeth in the large sprocket has an appreciable effect on the amount of joint wear (or pitch elongation) that can be accommodated by the chain before it tends to jump or ride over the teeth. This is illustrated by Chart B. Generally, a roller chain has reached its useful wear life when the elongation per pitch is in the range of 2% to 3% of pitch. As show in the chart, this would result in a maximum of 65-100 teeth for the large sprocket. This suggested maximum can be exceeded by making a more conservative chain selection.

Chain pitch • Use the smallest pitch chain that will handle the horsepower and load requirements. Single strand chains satisfy most requirements and are usually more economical. Use small pitch multiple strand chains for high speed drives or when quietness is desirable. This permits a larger number of teeth in the driver sprocket and results in smoother drive operation.

When space limits the diameter of the large sprocket, it may be necessary to select a smaller pitch, multiple strand chain to provide a sufficient number of teeth for the small sprocket.

Number of teeth for small sprockets • The recommended minimum number of teeth for the small sprocket varies with operating conditions. The recommended minimums are: Very slow speed drives .......... 12 teeth Slow speed drives .................. 17 teeth Moderate speed drives .......... 21 teeth High speed drives .................. 25 teeth

Drive ratio • The drive ratio is determined by the speeds of the driving and driven shafts. Properly engineered, drives with ratios up to 10:1 will perform satisfactorily. However, doublereduction drives with smaller ratios have better operating characteristics and are often more economical than a large ratio, single-reduction drive.

Hardened teeth • It is good practice to harden sprockets with 25 teeth or less when applied to: Very low speed, heavily loaded drives High speed drives Large ratio drives Abrasive or corrosive conditions For additional information consult Rexnord Industries, Industrial Chain North America Chart A : Variations in chain speed due to chordal action

Select relatively large diameter sprockets for 1:1 and 2:1 ratio drives, especially if required to operate on horizontal centers. This will assure adequate distance between the two spans of chain and prevent them from striking as wear accumulates. This is particularly important for drives on long, fixed centers with the slack chain span on top.

RECOMMENDED

NOT RECOMMENDED

Typical drive arrangements using chain tighteners are shown in the preferred drive arrangements below. Offset links may be used to adjust chain length when other means are not available. Single-pitch offset links and twopitch offset assemblies can be supplied. Offset assemblies are recommended for high speed or heavily loaded drives. Chain tension should be carefully maintained when the following operating conditions exist:

Large RECOMMENDED NOT RECOMMENDED pitch, single strand chains are usually most economical for small ratio drives on long centers.

Chain length • When possible use a chain length with an even number of pitches to eliminate the need for an offset link

Center distance • Sprocket centers must be more than 1/2 the sum of the sprocket outside diameters to avoid tooth interference.

Fixed centers • When sprocket centers cannot be adjusted, make a conservative drive selection by using a larger service factor than indicated. Also, provide good lubrication.

A suggested minimum center distance would equal the diameter of the large sprocket plus half the diameter of the small sprocket. Drives so proportioned also assure the minimum suggested chain wrap of 120° on the small sprocket.

Drives that operate at varying speeds such as power take-off drives from a torque converter, from an engine with a multi-speed gear transmission, or from a constant horsepower, variable speed electric motor, should be selected on a chain strength basis. The ratio of ultimate strength to maximum peak load should not be less than 6:1. The selection should be checked against the horsepower table for sufficient rating at the normal operating speed.

Chain tension • To 2 obtain maximum chain life, make provisions to maintain proper chain tension. Make an initial adjustment after approximately the first 100 hours of operation to remove slack caused by initial elongation. Thereafter, the frequency of periodic adjustments is governed by operating conditions.

Drives operating from variable speed, variable horsepower electric motors should be selected to meet the maximum load requirements. In selecting the chain pitch, consideration must be given to the range of speeds involved.

Preferred drive arrangements • The drive arrangements illustrated below are desirable for optimum life of the drive. The preferred direction of rotation is indicated for each arrangement, although arrangements A, B and C will operate C satisfactorily in either direction.B A

The simplest method of adjusting chain tension is to provide for movement of one shaft. This method is commonly used for drives operating from electric motors or internal combustion engines since they can be mounted on adjustable baseplates or slide rails.

AA AA

For fixed center drives, chain tension may be maintained by an automatic or manually adjusted chain tightener. Manually operated chain tighteners must be frequently checked for proper adjustment. The idler sprocket should have a minimum of 17 teeth and should be located adjacent to the driving sprocket so that at least 3 teeth N are in full engagement with the non-load-carrying PA span ofT Schain.

Drive Engineering Other arrangements • These arrangements are not generally recommended but they will give satisfactory service if carefully attended and chain tension is accurately maintained.

Fig. 6456

Operating conditions • The service factors listed in Table 1 page C-7 are for normal operating conditions. Increase these service factors to compensate for any of the following conditions: Heavy starting loads Frequent starts and stops Lubrication inferior to method recommended Short or fixed centers Vertical centers, particularly if the small sprocket is in the low position Two or more driven shafts Periodic load variation in a single revolution Reversals of drive rotation Inertia strains Large ratios Lubrication • Adequate lubrication is necessary for optimum drive life. A general guide to the recommended method of lubrication is indicated in the horsepower rating tables. These recommendations are based primarily on chain speed. For complete lubrication data, refer to pages C-45 and C-46. Useful formulas • Formulas for calculating horsepower, torque, chain speed, working load and similar values are given on page H-1.

Drive selection procedure Although horsepower and speed are the prime considerations for selecting a drive, the following information is also necessary: Source of power Horsepower to be transmitted Size and speed of driving shaft Driven equipment Size and speed of driven shaft Approximate center distance between shafts Relative position of shafts Space limitations With this information the selection procedure is as follows: Establish the service factor • Select a service factor from Table 1, page C-7, to compensate for the loads imposed on the chain by the type of input power and the type of equipment to be driven. If the exact driven equipment is not listed, use the factor for equipment with similar operting characteristics. Increase the service factor, if necessary, in accordance with the instructions under “Operating Conditions” above.

Establish the material or design variation factor • When a variation of standard roller chain is being selected (such as stainless steel chain for corrosion resistance), refer to Table 3 on page C-7 and determine the appropriate variation factor. This factor compensates for either the design or material difference so that a selection can be made from the standard roller chain rating table. Calculate the equivalent horsepower • Multiply the horsepower to be transmitted by the service factor (and by the variation factor, if applicable). This product is the equivalent horsepower or the value on which the chain selection is based. Select a trial chain • Standard roller chains are most commonly used and are selected from Chart C, page C-5. Single strand chains satisfy most drive requirements; however, multiple strand chains are often required for high speed drives, where space limits sprocket diameters, or where horsepower requirements exceed the capacity of single strand chains. Double-pitch chains are often used for slow speed, comparatively low horsepower drives on long centers. Use Chart D, page C-6, to make a trial chain selection. To make a tentative chain selection, project a horizontal line from the horsepower scale and a vertical line from the speed scale based on the equivalent horsepower and the RPM of the small sprocket. The area in which the two lines intersect indicates the probable chain requirement. It is often desirable to evaluate selections based on the next smaller or next larger chain size, especially if the point of intersection is near the border of an area.

Determine the number of teeth for the small sprocket • The ratings in the horsepower tables apply to single strand chains.

If a single strand standard roller chain or a double-pitch roller chain has been tentatively selected, refer directly to the horsepower rating table for the trial chain (see pages C-9 to C-43). In the column corresponding to the RPM of the small sprocket, find the rating nearest to the equivalent horsepower. Follow this line horizontally to the left to find the number of teeth required for the small sprocket. If a single multiple strand trial chain has been selected, the required rating per strand must be determined in order to use the rating tables. The required table rating per strand is calculated by dividing the equivalent horsepower by the appropriate multiple strand factor from Table 2, page C-7. Now, refer to the horsepower rating table for the trial chain. In the column corresponding to the RPM of the small sprocket, find the rating nearest to the required rating per strand just calculated. Follow this line horizontally to the left to find the number of teeth for the small sprocket. Check the small sprocket • Check the bore capacity of the sprocket selected, making sure it will accommodate the driving shaft. If the initial selection does not have adequate bore capacity, use a sprocket with larger number of teeth, or select a drive using the next larger pitch of chain. Determine the drive ratio • Divide the speed of the faster turning shaft by the speed of the slower turning shaft.

C-3

C


Determine the number of teeth for the large sprocket • Multiply the drive ration by the number of teeth in the small sprocket. If the drive is to operate in a restricted location, check the sprocket radii against the space limitation. Radial clearance required for each sprocket is equal to one-half the sum of its pitch diameter and the chain pitch. Encased drives require an additional 3" radial clearance. If sufficient space is not available, consider a smaller pitch, multiple strand drive. Calculate exact center distance and chain length • Formulas for these calculations are on page C-8.

C

Lubrication • The methods of lubrication shown in the horsepower rating tables are based primarily on chain speed; however, the relative position of driving and driven shafts often influence the method of lubrication. Recommendations and complete lubrication information are given on pages C-45 and C-46.

Drive selection example Problem Select a roller chain drive for the following conditions: Source of power Horsepower to be transmitted Size of driving shaft Speed of driving shaft Driven equipment Size of driven shaft Speed of driven shaft Approximate center distance Relative position of shafts Space limitations

Gearmotor 10 HP 2.438" diameter 100 RPM Bucket elevator uniformly fed 2.938" diameter 42 RPM 24.00" On same horizontal plane None

Check the small sprocket • As shown in the rating table, the maximum bore of a 17-tooth No. 100 sprocket is larger than the 2.438" bore required; therefore, the selection is satisfactory. Stock sprockets are readily available and are often more economical. Drive ratio • The drive ratio equals: 100 RPM = 2.38 to 1 42 RPM Number of teeth in large sprocket • The number of teeth in the large sprocket equals: 2.38 x 17 = 40.4 teeth. Use a 40-tooth sprocket. Center distance and chain length • Using the formula on page C-8, calculate the chain length as follows: A=

15.932-6.803 = .19000 2 x 24

From Table 4, page C-8, select the next higher listed value of .19081 for A. Corresponding factors for B, C and D are 1.9633, .4389, and .5611, respectively. The chain length in pitches equals: 1.9633 x 24 + (.4389 x 17) + (.5611 x 40) x 1.25 = 67.601 1.25 Use 68 pitches, which is the nearest even number. Calculate the exact center distance, using 68 pitches: E=

68 - (.4389 x 17) – (.5611 x 40) x 1.25 = 24.254" 1.9633

Lubrication • The No. 100 rating table specifies Type B bath or disc lubrication. For lubrication and bathing details, see pages C-45 to C-46.

Solution

The drive selected for this application consists of:

Service factor • The service factor listed in Table 1 on page C-7 for a uniformly fed bucket elevator driven by a gearmotor is 1.0.

17-tooth No. 100 driving sprocket 40-tooth No. 100 driven sprocket 68 pitches of No. 100 roller chain for 24.254” shaft centers, and an oil-retaining casing for oil bath lubrication.

Material or design variation factor • Since the listed conditions do not indicate the need for a variation in chain material or design, select a standard roller chain. Therefore, a variation factor does not apply. Equivalent horsepower • The equivalent horsepower equals: 10 x 1.0 = 10 HP Trial Chain • From Chart C, page C-5, note that the intersection of the 100 RPM vertical line and the 10 HP horizontal line falls in the area for No. 100 chain. Thus, the trial chain is No. 100 single strand. Small sprocket • In the No. 100 rating table, page C-23, the 100 RPM column lists 10.3 horsepower which corresponds closely to the equivalent horsepower of 10 required for this application. This rating is for single strand chain when used with a 17-tooth sprocket.

Chain length and center distance computations A center distance equal to the diameter of the large sprocket plus one-half the diameter of the small sprocket is the suggested minimum for average applications. An even number of pitches is desirable. However, if an odd number of pitches is required, offset links are provided. These symbols are used for the following formulas: e = desired sprocket centers in inches E = exact sprocket centers in inches g = pitch diameter of small sprocket in inches

G=pitch diameter of large sprocket in inches N=actual length of chain in pitches P=chain pitch in inches t=number of teeth in small sprocket T=number of teeth in large sprocket To determine the sprocket centers and chain length of a given drive, calculate factor A using the formula: A=

G-g 2e

Refer to Table 4 and select factors B, C and D corresponding to value A or the next higher value.

The number of pitches in the chain equals the sum of the pitches between sprockets and the pitches around the sprockets, or Number of pitches =

Be +Ct+DT P

The chain length should equal an even number of pitches so that the chain will couple without the use of an offset link. Therefore, select an even whole number nearest to the calculated number of pitches. Using this value as N, the exact sprocket centers is found by the following formula: E=

(N - C t - D T) P B

Drive Engineering Lubrication Generally, chains should be lubricated to achieve and maintain high operating efficiency and provide long service life. Factors such as operating conditions, chain size, type of service, and method of lubrication influence the life of chain. Many low-speed drives perform successfully with little lubrication, but where operating conditions permit, longer chain life will result from adequate lubrication. The primary purpose of chain lubrication is to provide a clean film of oil at all load-carrying points where relative motion occurs. To effectively lubricate the chain joints, oil must be delivered to the spaces indicated in Figure 7913. The oil should be directed to the inside of the lower span of chain so that it will not be thrown off by centrifugal force before it penetrates the chain joint.

Subsequent maintenance of a clean oil film between all bearing surfaces is equally important for high operating efficiency.

Selection of the lubricant Drives operating at room temperatures should be lubricated with an S.A.E. 30 mineral oil. For operation at high or low temperature extremes, oils with higher or lower viscosity numbers should be used, such as those listed below.

Petroleum oils should not be used to lubricate

Manual or drip lubrication may be used for open running drives (those enclosed by a safety guard) which operate in a non-abrasive atmosphere. These methods should be confined to low horsepower drives operating at low chain speeds. The lubricant may be applied to the clearances between sidebars with a brush, oil can, or drip-cup oiler. Drip-cups are usually mounted on a pipe with drilled holes spaced to distribute oil between the sidebars in the lower span of chain. About 4 to 10 drops per minute are sufficient to lubricate very slow speed drives, while a minimum of 20 drops per minute is recommended for higher speeds. The relative position of shafts is not a factor when these methods of lubrication are used. Bath lubrication is the simplest automatic method of lubricating encased chain drives and is highly satisfactory for low or moderate speeds.

operating conditions, chains operating in

highSIDE temperature atmospheres can be BETWEEN THE BARS TO THE PIN effectively lubricated with colloidal graphite dispersed in a suitable volatile carrier. These solutions penetrate the chain joints and, upon evaporation of the carrier, leave a thin deposit Fig. 7913 of graphite on the chain joint surfaces. This type of lubricant may be applied by Factory prelubrication ROLLER CHAIN drip-feed or wick-feed oil cups. Consult a Fig. 7913 lubricant manufacturer for recommendations Laboratory tests and actual experience show when chains are required to operate at ROLLER CHAIN that chain joint friction is greatest during the temperatures between 300°F and 700°F run-in period, the span of time between drive (149° and 371°C). start-up and the point at which the lubrication Fig. 7913

ROLLER CHAIN

system begins to function effectively. To minimize joint friction during this critical period of operation, Rexnord roller chains are factory prelubricated. Laboratory tests show that prelubrication reduces joint wear during the critical run-in period by approximately 50%. The result is longer operating life for the chain.

Suggested methods of lubrication Several methods for lubricating chain drives have been developed, each fitting a particular range of operating conditions. Horsepower, chain speed, and the relative position of shafts are primary considerations. The various methods suggested and their range of application are described below.

Fig. 6579

OIL LEVEL Fig. 6579

OIL LEVEL Fig. 6579

OIL LEVEL

The chain dips into an oil reservoir to a depth of about one-half inch, forcing the lubricant into the chain joints. Only a short length of chain should run through the oil, preferably only that portion on the bottom of the lower sprocket. The relative shaft positions illustrated below are recommended when oil bath lubrication is used: OIL LEVEL Fig. 5243

Disc lubrication is very effective for moderately high-speed drives and is frequently used when the drive arrangement is not suitable for oil bath lubrication.

C

Forced lubrication is recommended for large horsepower drives, heavily loaded drives, high speed drives, or where oil bath or oil disc lubrication cannot be used.

OIL LEVEL

Fig. 4245 Fig. 4454

An oil disc mounted on the lower sprocket dips about one-half inch into an oil reservoir. The oil is thrown off the disc by centrifugal force, automatically lubricating the chain which is kept above the oil level. This method of lubrication is ineffective at high speeds as well as at very low speeds. Oil disc lubrication is applicable to the relative shaft positions illustrated below:

An oil pump is provided to supply a continuous spray of oil to the inside of the lower span of chain. The circulation of the lubricant aids in the dissipation of heat and results in a well-lubricated, cooler operating drive. The pump is usually direct-connected to a fractional horsepower motor as illustrated in Figure 4245. A chain driven pump, operating from either the driving or driven shaft may be used where electric power is not available. Pumps of about one-gallon-per-minute capacity are adequate for most drives under 200 hp.

Drive Engineering Drive Installation

Accurate alignment, proper chain tension, good lubrication, and periodic inspection are required to obtain maximum chain and sprocket life. To assist you in safely installation chain and sprockets, careful attention should be given to the following instructions. 33635

Caution: Shut off all power to the equipment so that it cannot be started accidentally during these installation steps. Failure to do so can result in serious personal injury. Shaft alignment • Mount the sprockets on their respective shafts. As illustrated in Photo 33635, align the shafts horizontally with a machinist’s level, and adjust the shafts for parallel alignment with a vernier, caliper, or feeler bar. The distance between shafts on both sides of the sprockets must be equal. When shafts have been accurately aligned, the motor, bearings, etc., should be bolted securely in place so that alignment will be maintained during operation.

Aligning shafts

Sprocket alignment • Sprockets must be in axial alignment for correct chain and sprocket tooth engagement. Apply a straight edge, or heavy cord to the machined sprocket surfaces as shown in Photo 33636. When a shaft is subject to end flat, the sprocket should be aligned for the normal running position. Tighten set screws in sprocket hubs to guard against lateral movement and to hold key in position.

C

33636

Chain installation • Inspect chain to make sure it is free from dirt or grit before it is installed. Fit the chain around both sprockets bringing the free ends together on one sprocket as shown in Photo 33637. Insert connecting link and secure in place. Note: Due to their flexibility, chains can be somewhat difficult to handle. When installing the chain, pick it up by the end links to avoid the possibility of pinching fingers or hands. Failure to do so may result in personal injury.

Aligning sprockets

Chain tension • Adjust drive centers for proper chain tension, as outlined below. Normally, horizontal and inclined drives should be installed with an initial sag equal to approximately 2% of sprocket centers. Vertical center drives, and those subject to shock loading, reversal of rotation, or dynamic braking, should be operated with both spans of chain almost taught. Periodic inspection of such drives should be made to avoid operation with excessive slack and to maintain proper chain tension. To determine the amount of sag, pull one side of the chain taught allowing all the excess chain to accumulate in the opposite span. As illustrated in Photo 33638, place a straight edge over the slack span and, pulling the chain down at the center, measure the amount of sag. If necessary, adjust drive centers for proper sag that will result in correct chain tension. Inserting connecting link

PITCH PITCH

The feature of compactness is of particular advantage on applications where the conveyor is an integral part of a machine. Smooth operation may be achieved with standard roller chains because sprockets, with sufficient teeth to avoid chordal disturbance, are relatively small in diameter. In addition, precision construction provides accurate timing where this is an essential requirement.

Conveyor Chains Double Pitch Roller Chains CHAIN PITCH

CHAIN PITCH

Double-Pitch Conveyor chains are lower in cost than standard roller chains and are ideally suited for conveyor applications, particularly when shaft centers are relatively long. DoublePitch conveyor chains have straight side-bars of equal height and can be furnished with standard diameter or large diameter rollers. Standard diameter rollers are for applications where the chain slides along the conveyor path. The straight, equal height sidebars provide ample sliding surfaces to resist wear.

Fig. 6553A

Fig. 6553A

Chains with rollers larger in diameter than the height of the sidebars are used where rolling action along the conveyor path is desired. Large Delrin rollers can be furnished for applications that require minimum or no lubrication. Sprockets • Sprockets for Double-Pitch Conveyor chains with standard diameter rollers are normally furnished with two times the number of teeth required. As illustrated in Fig. 6553-A, the relationship between chain pitch and roller diameter results in adequate space for a second set of teeth which substantially increases sprocket life.

CHAIN PITCH

CHAIN PITCH

When the total number of teeth in the sprocket is 24 or more, stock sprockets for standard roller chains of one-half the conveyor chain pitch may be used. Sprockets for conveyor chains with large diameter rollers can only be furnished with the required number of teeth as illustrated in Fig. 6553-B.

Conveyor Chains Link-Belt® Redi-Lube™ Chain

Link-Belt® Redi-Lube™ chain is built for service comparable to that of ANSI roller chain and is interchangeable with the ANSI chain. However, Redi-Lube™ chain is self-lubricating. Like the ANSI chain, Redi-Lube™ is made in standard, single and multiple widths and Double-Pitch; the latter in two series—drive and conveyor.

Standard Group

Construction. Heavy-walled, oil-impregnated, sintered-steel bushings replace the conventional rollers and bushings of ANSI roller chain. Controlled interference fits between the bushings and link plates prevent tight chain joints, caused by the link plates backing off the bushings. Advantages. Redi-Lube™ chain, being self-lubricating, assures long wear life when lubrication is not possible or practical. This advantage in Redi-Lube™ chain only applies to chain speed ranges shown in the “Speed Range” table on following page.

W

D

E T

PITCH

Maximum operating temperature for Redi-Lube™ chain is 200° Fahrenheit. Built-in clearances and self-lubrication guard against corrosion and abrasion. Although these destructive elements cannot be entirely overcome, the constant presence of a lubricating film in the pin-bushing contact area minimizes their effect.

Conveyor Chains

Link-Belt® Hollow Pin chain is identical to ANSI Standard Roller Chain in pitch, roller width, and roller diameter. It is quality designed for long wear life in conveyor applications. The “hollow pin” feature provides unlimited conveyor design versatility.

Hollow Pin Chain

Link-Belt Hollow Pin chain is available in single pitch series or Double-Pitch series. The Double-Pitch series is furnished either rollerless or with large-diameter carrier rollers constructed of steel or Delrin. Advantages: Attachments or crossrods can be inserted at any desired spacing, which provides great design versatility. Changes can be made without removing the chain from the conveyor.

Single Pitch Carrier Roller Type

A

E

Ease of assembly of attachments or crossrods reduces assembly costs and maintenance time. There is less down-time in the event of a conveyor jam-up.

D

Standard ANSI sprockets can be used except on large-diameter carrier roller chain.

W

B

The type of connecting link used for all Hollow Pin chain is retaining ring (RR).

T

PITCH I.D.

Sprockets: Single pitch Hollow Pin chain uses standard stock sprockets. Double-Pitch Hollow Pin chain uses Double-Pitch sprockets.

H CONN LINK RETAINING RING TYPE RRCLK HOLLOW

Note:

PIN LINK

Attachments: Attachments of the A, K, M and D types are available as full extra connecting links with normal pins which insert through the hollow pins and are fastened on the other side by spring clips. This means that attachment assemblies are wider than the standard chain as shown on the attachment pages following. There are no attachments available for the inside (roller) links. Since the connecting link for the Hollow Pin chain is in itself a wider assembly than the standard Hollow Pin chain, the connecting link will not accept an attachment.

Hollow Pin Chain Attachments Standard types of attachments are available for Link-Belt速 Hollow Pin chain in both single and DoublePitch types. Special attachments and variations of the standards can be supplied on a made-to-order basis. Standard attachments are separate, complete links having long pins which are inserted thru the hollow pins of the chain. All standard attachments will fit chains with or without large diameter carrier rollers. It is recommended that all attachments be inserted in the pin link position of the chain. Hollow Pin chain provides great versatility in conveyor design. Various types of attachments may be stocked Wire mesh conveyor, using cross rods assembled to parallel strands of Hollow Pin Chain. for use on the same chain. Chain may be purchased in any desired length and assembled into a conveyor using loose attachments, adaptors, and/or cross rods in any desired spacing or arrangement. Attachments or cross rods may be inserted into any link in the chain without chain disassembly. Changes in attachments and in attachment spacing can be quickly accomplished while the chain remains on its sprockets. Standard attachments for Hollow Pin chain are similar to the A, K, M and D, ANSI standard single and DoublePitch attachments. Pages D-13 and D-14 describe typical examples of standard attachment applications. The attachments and the uses pictured on this page, while not standard, are typical of the versatility provided for by the unique features of Hollow Pin chain.

Conveyor Chains Side Bow Roller Chain

Side Bow Roller chain is an extra-clearance chain with the ability to permit side flexing and twisting. It is made of the same highquality materials and specifications, and undergoes the same manufacturing processes and precision finishing, as ANSI standard roller chain. This chain is constructed of standard ANSI roller links combined with special pin links designed to allow greater clearance between the pins and bushings and between the roller link and pin-link plates. Compensation of the pin-link pitch results in uniform chain pitch throughout.

A

Sprockets. For most applications, stock standard ANSI cut tooth sprockets or existing sprockets may be used. For special applications, sprockets may be made-to-order.

Conveyor Chains Block Chain Link-Belt® Block chain is precision-finished chain consisting of alternate block links and link plates, joined by pins. Solid blocks are made of sintered metal. Laminated blocks are made of laminated steel plates. All chain is 1-inch pitch, with block links varying from 3/16 - inch to 1/2 - inch in width. Pitch is measured between centers of alternate pins in a taut chain, instead of between centers of adjacent pins.

This chain is used in light-load, low-speed conveyors. Its broad surface can be dragged along a guide to reduce the catenary load on sprockets. Block chain length tolerance is –0 to +1/16" per foot. NOTE: NONCORROSIVE AND HEAT-RESISTANT BLOCK CHAIN—Stainless steel chains can be furnished on a made-to-order basis with laminated blocks only in riveted construction with cottered type connecting links. Sprockets. All Block Chain sprockets are made to order.

In keeping with modern machinery design, roller chains are widely used for conveyor service because of their appearance, availability, durability, and performance. Precision manufacturing assures long, dependable operation and economical service, while compactness and light weight result in minimum space and power requirements. Standard Roller chains used for conveyor and elevator service are the same as those used for power transmission drives. The Double Pitch Conveyor chains are similar to the drive chain series, differing principally in sidebar style. Compared to power transmission applications, chains for conveyor service operate at relatively slow speeds on longer centers and are not exposed to heavy sprocket impact from high velocity, or to the high frequency of joint articulation. Consequently, different methods are used in selecting chains for conveyors than for power transmission service. The procedure for selecting conveyor chains is outlined on page E-4. Use the following recommendations as a guide when selecting roller chains for conveyors. Chain types • Three general types of roller chains are used for conveyor applications: Standard Roller chains with suitable attachments are usually applied where sprocket diameters are restricted and smoothness of operation is essential. Most sizes are readily available in stainless steel for corrosive conditions. Double Pitch Conveyor chains are more economical than Standard Roller chains and are available with either standard diameter or large diameter rollers. Chains with standard diameter rollers are furnished for vertical conveyors or for applications where the chain slides on the edge of the sidebars. Chains with large diameter rollers are recommended when it is advantageous to reduce the power required to operate the conveyor. Flat-top chains in numerous styles are available for transporting containers of all types, small parts, packages, and countless other items through various processing operations. Top-plates attached to the chain form the carrying surface. Chain pitch • Although conveyor chains are usually selected on the basis of ultimate strength, it is often necessary to consider chain pitch. Chain pitch may govern, or be governed by, the size of the carrier or the attachment spacing. Consider short pitch Standard Roller chains, 35 through 80, for short conveyors or where smooth operation is required. For a given sprocket diameter, smaller pitch chains permit a large number of sprocket teeth; hence, less chain speed variation. See Chart A, page E-2. For longer conveyors, consider Double Pitch Roller chains. Larger pitch standard roller chains, numbers 100 through 160, are used for more heavily loaded conveyors. For long conveyors with heavy loading, consider Steel Engineering chains. Consult Rexnord Industrial Chain for specifications.

Multiple strand conveyors • When two or more strands of chains must operate abreast, strands are matched for uniform length and attachment location. Each 10-foot length is tagged to indicate the proper sequence of assembly. Sprockets should be keyseated in line with respect to a tooth or tooth space to assure an equal distribution of the load in all strands of chain. 1

Fig C-166

It is not necessary to couple the strands in numerical sequence unless more than one type of attachment is used in variable spacing. Operating temperature • Roller chains may be operated in moderately elevated temperature zones, as in baking and enameling ovens. The working factors listed in the table on page E-4 may be used when the chain temperature is below 350° F. Consult Rexnord Industrial Chain for operation at temperature above 350° F. Refer to page E-9 for information regarding lubrication at elevated temperatures. Chain joint bearing area • Chain joint bearing area is the pin diameter multiplied by the bushing length. Although this value is not directly used in the chain selection procedure, it can serve as an indicator of comparative wear life between two chains. For this reason, bearing area values are shown in the conveyor chain specification tables, pages D-3 to D-6. Catenary tension and chain sag • The formulas applying to the conveyor layouts on pages E-6 and E-7 do not consider catenary tension since most roller chain conveyors are designed to support the return span of chain. However, for short conveyors, it is not uncommon or undesirable to permit the return run to hang free. Longer conveyors are sometimes designed so that the major portion of the return run is supported, thus allowing the catenary tension in the unsupported section of chain to act as a takeup. When the return run of chain on a long conveyor is unsupported,

calculate the catenary tension due to chain weight and add it 11

to the chain pull so that the selection will be based on the total working load. Catenary tension should not exceed the chain pull and must be considered when calculating bearing loads and necessary shaft diameters, but is not a factor in determining the required horsepower to operate the conveyor.

Conveyor Engineering Engineering Recommendations

It is often desirable to determine the amount of sag to be expected in the unsupported slack span of a conveyor chain so that required clearances can be established. Table 5 below lists the approximate sag for various center distances.

Sprockets with at least 15 teeth are recommended; however, where greater operating smoothness is required, use sprockets with 21 or more teeth. Chart A illustrates the relationship between chordal action and the number of teeth in sprockets.

Use the following formulas to calculate chain sag and catenary tension, where:

Driving power • The driving power is usually applied to the head, or discharge, end of the conveyor. This arrangement is recommended so that only carrying run ofOF the conveyor WHEEL R =the PITCH RADIUS SPROCKET chain is under maximum tension. 180° r = R X COS T Chart A • Variations in chain speed due chordal action T = NUMBER OF to TEETH R = PITCH RADIUS OF SPROCKET WHEEL N = RPM 14 180° MINIMUM r = R X COS T CHAIN SPEED T = NUMBER OF TEETH A 13

Takeups • Locate takeups at the foot, or loading, end of the conveyor whenever practical. Screw takeups are ordinarily used but where fixed tension is required, such as on long conveyors subject to wide temperature variations, spring, gravity, or catenary takeups are recommended.

When operating in a clean atmosphere, lubricate the chain with a neutral grade of straight mineral oil that is fluid enough to penetrate the chain joint. When operating in an abrasive atmosphere lubricate the chain with a neutral petroleum jelly or a soft grease which, when heated, becomes sufficiently fluid to penetrate into the chain joint, but at operating temperature is solid enough to hinder the entrance of abrasive materials.

Takeups should have sufficient travel to permit removal of 2 pitches of chain.

When operating at elevated temperatures lubricate the chain with colloidal graphite dispersed in a suitable carrier. Complete data on lubrication methods and recommendations are on page E-9.

Catenary takeup Useful in long conveyors where the catenary can follow the drive sprocket, thereby relieving chain tension throughout the rest of the conveyor. The catenary provides “automatic” tensioning of the chain. Lubrication • Conveyor chains must be properly lubricated to give long, trouble-free service.

Conveyor Engineering Selection Procedure

Either standard or Double Pitch Roller chains, with suitable attachments, are most often used for conveying applications. Numerous attachments are available to accommodate slats, crossrods, and other commonly used conveying devices. The procedure for selecting the roller chains listed in Table 6 follows.

Roller chain selection procedure Preliminary information • Although chain pull and speed are the prime considerations in selecting a roller chain for conveyor service, the following information is also required. Type of conveyor Conveyor speed, feet per minute (FPM) Approximate center distance between shafts, feet Approximate diameter and bore of sprockets, inches Weight of material to be conveyed, per conveyor foot Kind of material to be conveyed Weight of carriers (slats, pans), per conveyor foot Size and spacing of carriers Type of attachment

With this information, the selection procedure is as follows: Select the layout • Refer to pages E-6 and E-7 and select the appropriate conveyor layout. Calculate the approximate conveyor pull • Calculate the approximate conveyor pull from the formula accompanying the layout. Since a chain has not yet been selected, value W will include the weight of slats, pans, or other carriers, and an approximate chain weight of 2 pounds per foot for each strand. Also, assume a takeup tension of 40 pounds for each strand of chain. Establish the working factor • Select a working factor based on the operating speed of the conveyor. The factors listed below apply to evenly loaded, well lubricated chains operating in a clean, non-abrasive atmosphere, and in a normal temperature environment. Increase the listed factors to compensate for any deviation from the operating conditions specified above. Working factor

Roller chain selection procedure (cont.) Determine the minimum conveyor strength required • Multiply the working factor by the approximate conveyor pull. The product is the minimum ultimate conveyor strength required. Determine the minimum chain strength required • Divide the minimum conveyor strength by the number of strands carrying the load. When the conveyor is designed to use two or more parallel strands of chain the required chain strength should reflect the distribution of load on each strand. If equal load distribution is assured, base the required chain strength for double strand conveyors on 1/2 the minimum conveyor strength requirement, 1 /3 for triple strand, etc. If the strands are not evenly loaded, divide the calculated minimum conveyor requirement by the number of strands that will normally handle the imposed load. For example, the chain selected for a four-strand conveyor may have to be based on two or three strands taking the full load at times, due to its distribution on the conveyor. Select the conveyor chain • Refer to Table 6 on page E-4 and select a chain with an ultimate strength slightly greater than the minimum requirement just calculated. The size of slats or pans, or the required spacing of attachments govern chain pitch. Make sure that the chain selected meets both pitch and strength requirements.

Chain length should equal an even number of pitches. Using the nearest even number of pitches as value N, calculate the exact sprocket centers from the formula: C = N–T× P 2 where C = exact sprocket centers, inches N = nearest even number of pitches P = chain pitch, inches T = number of teeth per sprocket When the number of teeth in the head and foot sprockets is unequal, chain length and exact sprocket centers are calculated from the formula on page C-8. Chain sag • The amount of sag in the slack span of chain is calculated from the formula on page E-2. Lubrication • It is usually advisable to lubricate conveyor chains. See page E-9 for methods and recommendations. Calculate the conveyor horsepower requirement • To calculate the horsepower required to operate the conveyor, use the formula in the appropriate conveyor layout, pages E-6 and E-7.

E

Check the chain selection • Refer to the formula previously used and compute the actual chain pull, considering chain weight (Table 6 on page E-4 ) and takeup tension now that a chain has been selected. Multiply the actual chain pull by the working factor to determine the minimum ultimate strength requirement. Check the result against the ultimate strength of the chain selected. If equal to or greater than the minimum requirement, the chain selection is satisfactory. Determine the number of teeth in the sprockets • Use sprocket pitch diameters listed for drive series Double Pitch chains (pages E-10 through E-23) for determining the number of teeth in the desired sprocket for use with conveyor series extended pitch chains. If possible, use sprockets with 15 teeth or more. Smoothness of conveyor chain operation is dependent upon adequate teeth in the driving sprockets, as illustrated in Chart A, page E-2. Calculate chain length and sprocket centers • When the number of teeth in the sprockets is equal, calculate chain length from the formula: chain length, in pitches = T + 2c P where c = center distance between shafts, inches P = chain pitch, inches T = number of teeth per sprocket

Coefficients of friction The factors in Tables 7 and 8 refer to roller chains operating on smooth, flat, clean tracks at normal operating temperatures. The factors should be increased when tracks cannot be kept clean. The coefficients of sliding friction in Table 7 apply when the conveyed load is carried by the edges of the chain sidebars or by the top plates of flat-top roller chains. The coefficients of rolling friction in Table 8 apply when the conveyed load is carried by double-pitch conveyor chains with large diameter rollers. Chains with standard diameter rollers are not recommended for rolling conveyors since the rollers may not always turn due to the small ratio between outside and inside diameters.

Selection Example

This example illustrates the method of selecting a conveyor chain solely on the basis of ultimate chain strength. Attachment spacing, appearance, or other factors may make it desirable to use a larger, higher strength chain than the minimum indicated by the conveyor pull formula and working factor.

Solution Select the layout • Layout A on page E-6 illustrates a horizontal conveyor with chain rolling and material carried. Calculate the approximate conveyor pull • As indicated in the selection procedure, certain assumed values are used in the layout formula at this point. Chain weight = 2 lbs. per foot per strand Take-up tension = 40 lbs. per strand Rolling friction factor = .12 Using these values, the approximate conveyor pull is the sum of the following: Pull on loaded run

Establish the working factor • The working factor listed on page E-4 for a chain speed of 200 feet per minute is 14.

Determine the minimum conveyor strength required • The minimum requirement is: 721 x 14 = 10,094 pounds Determine the minimum chain strength required • Since this is a double-strand conveyor, with each strand evenly loaded, the minimum chain strength per strand is 10,094 ÷ 2 or 5,047 pounds ultimate strength. Select the chain • Since a rolling chain is desired, refer to Table 6 and tentatively select C 2052 chain which has large diameter rollers and an average ultimate strength of 6100 pounds Check the chain selection • From Layout A, compute the actual conveyor pull, using the weight of C 2052 chain shown in Table 6. Since the actual takeup pull is not known, use .3% of the ultimate strength of C 2052 chain for each strand. Also use the rolling friction factor for C 2052 shown in Table 8. The actual conveyor pull is the sum of the following: = 506# PL = [5 + (2 x .83) + 70] 60 × .11 PR = [5 + (2 x .83)] 60 × .11 = 44# PTU = .003 × 2 × 6100 = 37# PR × .1 = 44 × .1 = 4# Total conveyor pull (PCV) = 591# Minimum conveyor strength = 591 × 14 = 8274# Minimum chain strength per strand = 8274÷ 2 = 4137# The selection of C 2052 chain with an ultimate strength of 6100 pounds is satisfactory. Determine the number of teeth in the sprockets • Refer to the listing for 2050 sprockets on page E-12. Note that a 19-tooth sprocket has a pitch diameter of 7.595" which is slightly less than the appropriate outside diameter of 8.250" desired, and that they will readily accommodate the 1.938" bore requirement. If a distance of 8.240" between the carrying and return runs is satisfactory, use 19-tooth sprockets. Calculate the chain length and sprocket chains • Since the number of teeth in the sprockets are equal, the chain length from the formula on page E-5 is: 19 + 2(60 × 12) = 1171 pitches. Use 1172. 1.25 Exact sprocket centers, based on 1172 pitches, are: C = 1172 - 19 × 1.25 = 720.625", or 60' .625" 2 Lubrication • Refer to page E-9 for recommendations. Calculate the horsepower requirement • Use the formula accompanying Layout A to determine the horsepower requirement of the conveyor drive. HP = (591 - 37) × 1.2 × 200 = 4.03 33,000


Lubrication The primary purpose of chain lubrication is to provide a clean film of oil at all load carrying points where relative motion occurs. This is particularly important during the initial break-in period when the wear characteristics of the chain are being established. Consequently, most chains are pre-lubricated at the factory unless otherwise specified. To be effective, subsequent lubrication must be directed to the bearing surfaces as shown in Figure C-147.

Elevated temperatures • Petroleum oils should not be used to lubricate conveyor or elevator chains operating in temperatures exceeding 300°F (149°C). Under certain conditions, chains operating in high-temperature atmospheres can be effectively lubricated with colloidal graphite dispersed in a suitable volatile carrier. The solution penetrates the chain joints and, upon evaporation of the carrier, leaves a thin deposit of graphite on the chain joint surfaces. The lubricant may be applied by drip-feed cups, provided agitation is used. Consult a lubricant manufacturer for recommendations when chains are required to operate at elevated temperatures. Corrosion • The effect of unusual corrosion conditions can sometimes be reduced with special lubricants. Consult a lubricant manufacturer for a material that is not soluble in the corrosive element.

As a general rule, lubrication of conveyor and elevator chains is necessary to obtain adequate chain life. However, there may be some applications where little or no lubrication is permissible. Meat packing and food processing plants are typical examples where contamination of the conveyed material must be avoided. Likewise, the presence of lubricant in a very dusty or abrasive environment could be a deterrent to long chain life. In these cases, lubrication decisions must often be based on actual experience.

Selection of the lubricant Conveyor and elevator chains operating at room temperature should generally be lubricated with a straight mineral oil of S.A.E. viscosity number 30. Lower or higher ambient temperatures require oils with lower or higher viscosity numbers, respectively. The following operating conditions require special lubricants:

High loads • When chain joints are subject to high unit bearing loads, use an “ EP” oil. This type of lubricant has an extreme pressure additive that helps maintain a cushioning film of oil between joint components.

Methods of lubrication It is difficult and generally impractical to provide protective housings for chains applied to conveyors and elevators. They are usually operated in the open and exposed to the material being conveyed. Therefore, applying a lubricant is difficult under some operating conditions. Various methods are used to lubricate conveyor and elevator chains. The nature of the surrounding atmosphere is the principal consideration in selecting the best method to use. Clean atmosphere • Chains operating in a relatively clean atmosphere can be lubricated manually or by a semiautomatic method using drip cups. The lubricant may be applied manually 99 with a brush or spout-type oil can to the spaces shown in Figure C-147.

With the semi-automatic method, dripcups are usually mounted on a pipe with drilled holes spaced to distribute oil between the sidebars in the lower span of chain. About 4 to 10 drops per minute are usually sufficient to lubricate slowspeed conveyors. It will take about one hour to drop one ounce of oil at the rate of 10 drops per minute. Atmosphere laden with lint or nonabrasive dust • Where large volumes of lint or non-abrasive dust are present, a brush or wiper can be used to clean the chain and apply the lubricant. Otherwise, the lint or dust will clog the chain joint clearances and prevent the oil from penetrating into the joints. This type of lubrication can be made to operate automatically. Abrasive atmosphere • If abrasives come in contact with the chain, lubrication becomes more difficult. When lubricants are applied externally, abrasive particles tend to adhere to the chain surfaces and act as a lapping or grinding compound. Under extreme conditions, it is sometimes advisable to avoid chain lubrication. Chains operating in an abrasive atmosphere can often be lubricated with a neutral petroleum jelly such as petrolatum, or with various other nonfluid lubricants such as greases with or without molybdenum disulfide or colloidal graphite additives. When properly heated, these lubricants are sufficiently fluid to penetrate the chain joints, but at normal temperatures are solid enough to hinder the entrance of abrasive materials. To lubricate a chain with petroleum jelly or non-fluid greases, heat the lubricant until fluid. Immerse the chain and allow it to soak until air bubbles cease to rise, thus indicating that the lubricant has penetrated the chain joints. Allow the chain to remain submerged until the lubricant is partially solidified to prevent the lubricant from draining out of the joints when the chain is removed. Before relubricating, thoroughly clean chain to remove all dirt and abrasives.
