SURE-FLEX CAPABILITIES

4-WAY FLEXING ACTION absorbs all types of shock, vibration and misalignment TORSIONAL Sure-Flex coupling sleeves have an exceptional ability to absorb torsional shock and dampen torsional vibrations. The EPDM and Neoprene sleeves wind-up approximately 15° torsionally at their rated torque. Hytrel sleeves will wind-up about 7°.

ANGULAR The unique design of the Sure-Flex coupling’s teeth allows for the absorption of angular misalignment without wear. Refer to page F1—18 for actual allowable misalignment limits. These limits allow for the alignment of the coupling using only a scale and calipers.

PARALLEL Parallel misalignment is absorbed without wear or appreciable energy losses. The lateral flexibility of the coupling sleeve minimizes radial bearing loads normally associated with parallel misalignment. This feature also allows for easier installation by the use of components bored for slip fits without fretting corrosion occurring at the shaft. Refer to page F1—18 for parallel misalignment limits. Only a straight-edge and feeler gage are required to obtain these limits.

AXIAL Sure-Flex couplings may be used in applications with limited axial shaft movements. The axial compressibility of the EPDM and Neoprene sleeves allows for shaft endfloat without the absolute transfer of thrust loads.

SURE-FLEX FEATURES

EASY, QUICK INSTALLATION

NO LUBRICATION, TROUBLE-FREE OPERATION

Sure-Flex can be installed quickly and easily, because there are no bolts, gaskets, covers or seals. Alignment can be checked with a straightedge placed across the outside of the precision-machined flanges. No special tools are needed for installation, alignment or removal.

The teeth of the sleeve lock into the teeth of the flanges without clamps or screws, tightening under torque to provide smooth transmission of power. There is no rubbing action of metal against rubber to cause wear. Couplings are not affected by abrasives, dirt, or moisture. This eliminates the need for lubrication or maintenance, provides clean, dependable, quiet performance.

SURE-FLEX SLEEVE SELECTION

Flexible sleeves for Wood’s Sure-Flex couplings are available in four materials (EPDM Neoprene, Hytrel and Urethane) and in three basic constructions. Characteristics of the materials are given on page F1—4 and the various types are shown and described here. JE-JES-JN-JNS J sleeves are molded EPDM rubber (E) or Neoprene (N). They are available in one-piece solid construction (JE, JN) or one-piece split construction (JES, JNS). These sleeves may be used in any Sure-Flex flange within a given size. Types JES, JNS

JE, JN

E-N These sleeves are of two-piece design with a retaining ring. They are available in either EPDM (E) or Neoprene (N). They may be used with any flange within a given size. Sleeves are shown here assembled and disassembled. E and N (Assembled)

Types E and N (Disassembled)

H-HS-U H (Hytrel) and U (Urethane) sleeves, designed for high-torque applications, transmit four times as much power as an equivalent EPDM or Neoprene sleeve. Available in one-piece solid construction (H or U) or two-piece split construction (HS), these can be used only with S, C and SC flanges. They cannot be used with J or B flanges or as direct replacements for EPDM or Neoprene sleeves.

*On applications involving varying torque loads, design around the maximum load. Then determine the resulting service factor at minimum load. If this value is greater than 4.0, special coupling alignment will be required (see page F1—18). Caution: Applications involving reciprocating engines and reciprocating driven devices are subject to rotational vibrational critical speeds which may destroy the coupling. The factory can determine these speeds when the rotational inertia (WR2) of the driveR and driveN units is known.

3. If coupling to the shaft of a 60 HZ AC motor, you may refer to page 8, locate the correct chart & columns for your sleeve material, motor speed and service factor; you can read the coupling size across from the motor horsepower. Example: For 150 HP @ 1750 RPM and 1.5 Service Factor - Use #13 EPDM or Neoprene or #10 Hytrel or Urethane. 4. For other speeds, use the following formula to calculate the required coupling horsepower rating @ 100 rpm. HP @ 100 rpm = HP x Service Factor x 100 / coupling RPM 5. Use the chart below to find a coupling with a HP @ 100 RPM rating which is greater than calculated above. Example: For 5 HP @ 55 RPM and 1.25 Service Factor: HP @ 100 = 5 x 1.25 x 100 / 55 = 11.36 Use #12 EPDM or Neoprene or #9 Hytrel with rating of 11.4 HP.

TYPE J SURE-FLEX BTS – FOR CLOSE COUPLED APPLICATIONS FLANGES Type

J flanges size 3 and 4 are manufactured of sintered carbon steel. The powdered metal manufacturing process provides high dimensional accuracy and uniform material properties for high strength. Size 5 and 6 are made of high strength cast iron. All flanges are bored-to-size for a slip fit on standard shafts. The outside diameter of the flange is machined so the surface can be used to check alignment without a special tool. Type J flanges can be used with sleeves of any construction except the Hytrel. Each flange has a keyseat and one (1) setscrew over the keyway.

COUPLINGS

Type J Sure-Flex Couplings are bored-to-size. Normally, they employ the one-piece JE sleeve, or the onepiece JES sleeve with saw cut to permit replacement where there is insufficient gap between shafts. Spacing between internal flange hubs equals G. Spacing between shafts should be greater than 1/8 in. and less than L minus .85 times the sum of the two bore diameters. To order complete couplings, specify coupling size with flange symbol (J) giving bore and keyseat. Refer to page F1–3 to order the required coupling.

TYPE S SURE-FLEX BTS – FOR CLOSE COUPLED APPLICATIONS

COUPLINGS Type S Sure-Flex couplings are normally supplied with the twopiece E sleeve. However, any of the sleeves shown on page F1—5 can be used with Type S flanges. Spacing between internal flange hubs equals L minus 2 times C. Spacing between shafts should be greater than 1/8 in. and less than L minus .85 times the sum of the two bore diameters. To order complete couplings, specify coupling size with flange symbol (S) giving bore and keyseat. Refer to page F1—3 to order the required coupling.

TYPE B BUSHED-FLEX QD – FOR CLOSE COUPLED APPLICATIONS FLANGES Type B flanges are made of highstrength cast iron the same as Types S, C and SC Sure-Flex flanges. Type B, however, is designed to accommodate Wood’s Sure-Grip Bushing for easy installation and removal.

BUSHINGS Sure-Grip Bushings offer convenient mounting of the flange to the shaft securely without setscrews. They are tapered and are split through both the bushing flange and taper to provide a clamp fit, eliminating wobble, vibration and fretting corrosion. This is the same bushing used in Wood’s sheaves and pulleys and is readily available everywhere.

SURE-FLEX® COUPLINGS Installation Instructions Sure-Flex flanges (outer metallic parts) and sleeves (inner elastomeric members) come in many sizes and types. First, determine the size and type of components being used. Remove all components from their boxes, and loosely assemble the coupling on any convenient surface. (Do not attempt to install the wire ring on the two-piece E or N sleeve at this time.) Also check maximum RPM values in the table against operating speed. All rubber sleeves (EPDM and Neoprene) have the same ratings for a given size and may be used interchangeably. However, because rubber and Hytrel sleeves have completely different ratings, they never should be used interchangeably. Inspect all coupling components and remove any protective coatings or lubricants from bores, mating surfaces and fasteners. Remove any existing burrs, etc. from the shafts. Slide one coupling flange onto each shaft, using snugfitting keys where required. When using Type B flanges, follow the instructions furnished with the Sure-Grip bushing. Position the flanges on the shafts to approximately achieve the Y dimension shown in the table. It is usually best to have an equal length of shaft extending into each flange. Move one flange to its final position. Torque fasteners to proper values. Slide the other flange far enough away to install the sleeve. With a two-piece sleeve, do not move the wire ring to its final position; allow it to hang loosely in the groove adjacent to the teeth.

Check angular alignment with a micrometer or caliper. Measure from the outside of one flange to the outside of the other at intervals around the periphery of the coupling. Determine the maximum and minimum dimensions without rotating the coupling. The difference between the maximum and minimum must not exceed the figure given under “Angular” in the table. If a correction is necessary, be sure to recheck the parallel alignment.

1 2 3

Parallel

MAXIMUM RPM AND ALLOWABLE MISALIGNMENT Sleeve Maximum Size RPM 3 4 5 6 7 8 9 10 11 12 13 14 16

Slide the loose flange on the shaft until the sleeve is completely seated in the teeth of each flange. (The “Y” dimension is for reference and not critical.) Secure the flange to the shaft. Different coupling sleeves require different degrees of alignment precision. Locate the alignment values for your sleeve size and type in the table. Check parallel alignment by placing a straight-edge across the two coupling flanges and measuring the maximum offset at various points around the periphery of the coupling without rotating the coupling. If the maximum offset exceeds the figure shown under “Parallel” in the table, realign the shafts.

Note: Values shown above apply if the actual torque transmitted is more than 1/4 the coupling rating. For lesser torque, reduce the above values by 1/2. *Type H and HS sleeves should not be used as direct replacements for EPDM or Neoprene sleeves.

If the coupling employs the two-piece sleeve with the wire ring, force the ring into its groove in the center of the sleeve. It may be necessary to pry the ring into position with a blunt screwdriver.

Install coupling guards per OSHA requirements.

CAUTION: Coupling sleeves may be thrown from the coupling assembly with substantial force when the coupling is subjected to a severe shock load or abuse.

HD ELASTOMERIC COUPLINGS

SECTION F4

Couplings require no lubrication and have proven to be technically superior, low in cost, simple in design, rugged, corrosion resistant, and maintenance-free. These couplings will tolerate substantial misalignment, and control shock loads. Replacement of the urethane rolls, if required, is a simple operation, taking a matter of minutes and involving no special skills or tools. Installation and alignment is quick and easy.

ROLL UNDER LIGHT LOAD.

ROLL UNDER HEAVY LOAD.

The diagram above shows how the coupling accommodates parallel misalignment. Note the black roll shifting position in its pockets as the hubs rotate. The action under angular misalignment can be seen from the diagram at the right.

FORM-FLEX FLEXIBLE DISC COUPLINGS ®

• Long Life • Low Maintenance • Design Flexibility

F5–1

FORM-FLEX METAL DISC FLEXIBLE COUPLINGS Form-Flex couplings transmit torque while compensating for angular, parallel and axial misalignment between two connected shafts. Flexible disc couplings minimize the misalignment forces on the connected equipment. The Basic flex coupling consists of two hubs, a spacer and two flexible discs. The flex disc is an assembly of thin metal laminations. In figure shown below, flex disc holes A & C are bolted to the hub and holes B & D are bolted to the spacer. Torque is transmitted in direct tensions from A to B and from C to D through the flex disc. Misalignment is taken through bending in the link between the bolt holes.

COOLING TOWER DRIVES

VERTICAL PUMP DRIVES

Form-Flex metal disc couplings are widely used in cooling fan drive applications. Form-Flex 4 bolt disc couplings offer more misalignment capacity than any competing metal disc design.

For smaller towers up to about 100 inches DBSE, TB Woodâ&#x20AC;&#x2122;s offers steel and composite spacer tubing options. TrueTube composite torque tubes are lighter than steel and eliminate thermal growth and vibration problems.

Form-Flex composite floating shaft couplings are recommended as a replacement for older multi-section drivelines. Composite couplings can span up to 240 inches without high maintenance center support bearings.

F5â&#x20AC;&#x201C;2

Form-Flex floating shaft couplings are a costeffective, maintenance free alternative to cardan U-joints for vertical pump drivelines. Form-Flex couplings are available with either steel or composite spacer tubing. Composite spacer tubing can reduce total cost by eliminating the need for bearings and support structures.

TYPICAL APPLICATIONS

PAGE

Single flexing couplings compensate for angular and axial misalignment only. Single couplings should only be used in a three bearing system with a self-aligning bearing as shown in the illustration. Single couplings may also be used in pairs to support a clutch, transducer or other system component. These arrangements are double flexing and must be used with two fully supported shafts as described below.

AR BH HH

F5–12 F5–13 F5–14

Close couple designs accommodate angular, parallel and axial misalignment types where two fully supported shafts are located very close together. Close shaft separations are generally in the range of 1/8 to 2 inches.

AX AA AY BY BA DA

F5–15 F5–16 F5–17 F5–18 F5–19 F5–19

Spacer couplings are used to connect fully supported shafts with wider separations than can be reached with a close couple design. Spacer couplings allow room for installation and maintenance without moving the connected equipment. Shaft separations are generally in the range of 3 to 12 inches. These couplings accommodate angular, parallel and axial misalignment.

Floating shaft couplings are spacer style couplings which are designed to connect widely separated shafts. The coupling spacers are fabricated. Both steel and TrueTube composite tubing options are available.

FLOATING SHAFT COUPLINGS

PAGES SERIES

Semi-floating shaft couplings are a special single flex version of the floating shaft coupling. These may be used alone for some applications or in combination with floating shaft couplings and pillow block bearings to span long distances. Composite floating shaft couplings should be considered as an alternative to multiple span applications with center bearings.

MICRO COUPLINGS DOUBLE FLEX

Form-Flex Micro Couplings are used for precision low torque applications. They are a smaller version of our 4 bolt line. Micro Couplings are constructed of aluminum for reduced inertia. Close couple and spacer designs are available.

F5-5

SELECTING AND ORDERING FORM-FLEX COUPLINGS 1) Select correct service factor from the chart below. 2) Calculate HP @ 100 or Design Torque (in lbs). HP @ 100 = HP x service factor x 100 coupling RPM OR Design Torque (in lbs) = 63025 x HP x service factor coupling RPM OR Design Torque = Torque (in lbs) x Service Factor 3) Compare this to the HP @100 column or the Rated Torque column. 4) Check other limiting factors such as bores and overall dimensions. 5) Standard Four or Six bolt couplings can be ordered as hubs and a center assembly. All other couplings should be ordered by description.

SERVICE FACTOR TABLE These service factors assume a smooth motor or turbine type driver. The adders listed for other driver types must be added to the service factor shown for the driven equipment.

Other coupling series can be altered to comply with API610. NEMA MG1-14.37 AND MG1-21.81–All Form-Flex metal disc couplings meet these standards without limited end float devices Certain tables and data in this catalog were extracted from the reference AGMA standards with the permission of the publisher, the American Gear Manufacturers Associations, 1901 North Meyer Drive, Arlington, VA 22209. MATERIAL CLASSES APPLICABLE TO 4 AND 6 BOLT DESIGNS CLASS A– Mild steel hubs and spacer, alloy steel hardware, 300 series stainless steel flex discs. CLASS B– Zinc plated mild steel hubs and spacer, alloy steel hardware, 300 series stainless steel flex discs. CLASS C– Zinc plated mild steel hubs and spacer, 300 series stainless steel hardware and flex discs. CLASS E– All 300 series stainless steel construction. DYNAMIC BALANCING RECOMMENDATIONS Use this graph to determine the appropriate balance class based on coupling weight and operating speed. The balance classes listed on the graph are for equipment with average sensitivity to coupling unbalance. The user should determine how sensitive the equipment train is to coupling unbalance. Use one balance class higher if your system has higher than average sensitivity to unbalance. Use one balance class lower if your system has lower than average sensitivity to unbalance. Use this guide to check your coupling selection against the recommended balance class for your operating conditions. The following factors should be considered when determining a machine’s sensitivity to coupling unbalance. 1) Shaft End Deflection: Machines having flexible shaft extensions are relatively sensitive to coupling unbalance. 2) Bearing Load Due to Coupling Weight Relative to Total Bearing Load: Machines having lightly loaded bearings, bearings that are primarily loaded by the weight of the coupling or other overhung weight are relatively sensitive to coupling unbalance. 3) Bearing, Bearing Support and Foundation Flexibility: Machines or systems with flexible foundations for supports for the rotating elements are relatively sensitive to coupling unbalance. 4) System Natural Frequencies: Machines operating at or near natural frequencies are sensitive to coupling unbalance. 5) Machine Separation: System having widely separated machines are relatively sensitive to coupling unbalance. 6) Shaft Extension Relative to Bearing Span: Machines having a short bearing span relative to their shaft extensions are sensitive to static unbalance. HOW FORM-FLEX COUPLINGS ACCOMMODATE MISALIGNMENT Double flexing metal disc couplings may be used to accommodate angular, parallel and axial misalignment. Single flexing couplings may only be used to accommodate angular and axial misalignment. A metal disc type coupling uses a double hinge effect through two flexible discs and the spacer to compensate for parallel offset misalignment between shafts. Parallel misalignment imposes the same angular deflection (A) on each flex disc. Angular misalignment of either connected shaft, (B), creates additional angular deflections which are added to the angular offset due to parallel misalignment. The total misalignment angle, (C), at the flex disc is equal to the angular offset due to parallel misalignment (A) plus the angular offset due to angular misalignment (B). The maximum misalignment angle (C) should never exceed the rated misalignment capacity of the coupling type being used. Machinery equipment changes in actual operation and over the life of the equipment. We recommend that the machinery misalignment be set as close to zero as possible when a coupling is installed. We recommend keeping the measured misalignment below 25% of the rated misalignment capacity of the coupling type used when the machinery is installed and aligned. The remaining coupling misalignment capacity will then be available to accommodate additional misalignment caused by foundation shifts, vibrations, thermal growth or other causes.

CLOSE COUPLE – BY SERIES 6 BOLT CLOSE COUPLED COUPLING The BY series close coupling is a low cost replacement for gear or elastomeric couplings. It is ideal for use in low to moderate speed applications with motor or turbine drivers. The BY is an economical alternative to Axial Split spacer designs. The BY accommodates close shaft spacings by allowing the connected shafts to extend through the flex discs and spacer without restriction. The spacer is not service removable if the shaft gap is less than the D1 dimension shown. For shorter shaft spacings, the flex discs may still be replaced by removing the coupling bolts and shuttling the spacer from side to side. Inverted (BY) and Extended (BH) hubs are available to allow varying shaft diameters and spacing.

CLOSE COUPLE – BA SERIES-6 BOLT DESIGN & DA SERIES-8 BOLT DESIGN AXIAL SPLIT SPACER COUPLINGS Axial split spacer couplings are an ideal replacement for lubricated gear or grid couplings. Close shaft separations are met without requirements for extending shafts through hubs. The split spacer removes radially to allow removal of connected equipment. Flex discs may be replaced without disturbing the connected equipment. The axial split series features all steel construction. Stainless steel flex discs are standard for the BA series. Both stainless and high strength alloy steel flex disc options are available with the DA series.

TRUE TUBE ™ COMPOSITE TORQUE TUBES

True-Tube composite tubes are high-strength, lightweight torque tubes for long span drive shafts. These tubes are filament wound carbon or glass fiber construction in an oven cured epoxy matrix. True-Tube composites offer the following advantages over steel tubing.

LONGER SPANS TrueTube composite tubes have a higher stiffness to weight ratio than steel tubing. That increases the critical speed of the tubing and allows longer spans without center bearings.

LIGHT WEIGHT TrueTube drive shafts weigh up to 80% less than equivalent steel driveshafts. That means better balance and reduced vibration. Bearing life may be improved by minimizing overhung weight.

DESIGN FLEXIBILITY TrueTube composite tubes may be custom designed to meet your requirements for torsional stiffness, critical speed or torque capacity. With TrueTube, a designer can tune torsional or lateral critical speeds out of a machine system. All TrueTube products include an ultraviolet barrier that is wound into the structure of the tube before it is cured. This UV barrier eliminates the need for paints or other protective coatings and results in a smooth, durable finish that other composite tubes don’t offer. TrueTube products are cured in an enclosed oven to assure consistent strength and quality. Design data is shown below for standard series tubes. Standard series tubes are designed for maximum length at moderate torques. High torque designs are also available. MODEL NUMBER

M SERIES – 4 BOLT MICRO COUPLINGS

Form-Flex M series microcouplings are a more compact and lighter design than traditional A Series couplings. They are free from backlash and their high torsional stiffness makes them ideally suited for small servo and tachometer drives. Aluminum hub construction meets low inertia requirements while the bolted assembly provides superior life when compared to riveted types.

STYLE MA This coupling style is available in size 04 only. It features a machined spool type spacer. Custom length spacers are also available.

STYLE MB

STYLE MC

This coupling style features a minimum length block spacer. Standard flanged hubs are supplied with the coupling. Style MB is a good, general use coupling.

This style features the MB style minimum length spacer and an oversize bore capacity. The style MC provides the shortest overall coupling length.

COOLING TOWER COUPLINGS

The traditional A5 design features all metal construction. It can be ordered to meet any custom spacer length. A wide variety of materials and finishes is available.

Designed specifically as a connection for cooling tower applications and other drives requiring long shaft spans. Form-Flex couplings with TrueTube composite tubing weigh less than half of its steel counterpart and can span shaft separations of up to 240 inches. They are easy to handle, install and maintain. TrueTube composites are extremely corrosion resistant and are custom designed to provide the optimum combination of torsional strength and lateral stiffness for cooling tower drive applications. TB Woodâ&#x20AC;&#x2122;s proprietary composite flange design transmits torque reliably from the metal outboard hubs to the composite flange and into the TrueTube composite tube.

HD elastomeric couplings and TrueTube composites are combined into a high misalignment, all composite coupling. These couplings are easy to install and align. Their high misalignment capacity makes them ideal for smaller, wood framed and fiberglass towers.

Ordering Standard gear coupling product is sold by component See examples on individual pages

GEAR COUPLING SELECTION Calculate Design Horsepower or Design Torque • If HP and RPM are Known, Calculate Design HP@100 RPM Design HP@100 RPM=(Prime mover HP x Service Factor x 100) divided by the Coupling RPM Refer to the HP@100 RPM rating for the coupling style desired. Select the coupling equal to or greater than the calculated design HP@100 RPM. Check the maximum bore capabilities to be sure the size coupling you have chosen is capable of your largest bore. • If Using Prime Mover Torque, Calculate Design Torque Design Torque = Prime Mover Torque x Service Factor Refer to torque rating in the coupling style desired. Select the coupling equal to or greater than the calculated design torque. Check the maximum bore capabilities to be sure the size coupling you have chosen is capable of your largest bore. The above selection can be used for all series of industrial gear couplings, however, the Deck-Flex and Deck-Flex Mite couplings have their own calculations.

Blind assembly couplings can be produced by ordering a 3 groove sleeve (GDFS3 or GDFMS3) and installing a center retaining ring. With the addition of this center retaining ring, the outer rings are not needed and the installation involves no more than sliding the hubs into the sleeves.

RIGID COUPLINGS Ribbed Type Compression Couplings are recommended for emergency and regular service on heavily loaded shafts. These couplings are bored true to shaft size, and the halves are separated during boring operation to allow for clamping when halves are drawn together. Bolt heads and nuts are protected by flanges. End flanges are faced square with bore, and outer diameters are turned. To facilitate the use of V-belt drives, sufficient space may be left between shaft ends when mounting the coupling to permit easy replacement of belts.

This coupling is designed to provide a simple method of rigidly connecting two pieces of shafting. The standard Sure-Grip tapered bushing is used, one on each shaft, to securely clamp the two shafts together. The precision tapered fit lines up the two shafts. No press or shrink fits are necessary.
