Maintenance Rocks When Opportunity Knocks
n a recent trip to Paris, I reveled in the role of tourist. Among other points of interest, I visited the military academy/museum at the Place Invalides. There, I couldn’t help but chuckle when my electronic “guide” referenced the graduation report for one of this college’s most celebrated alums—Napoleon Bonaparte. The report writer had evidently noted something to the effect that “given the right circumstances,” Napoleon would be able to “make something of himself.” What an understatement! Although Napoleon was greatly disadvantaged due to his Corsican background, he was a master at recognizing opportunity. He used his savvy to open door after door for himself and, in just a few short years, became the legitimate Emperor of France. Fast forward several centuries to a Planning and Scheduling workshop I conducted three weeks after trekking around Paris… My introduction of the work-order backlog management section was met with an all-too-familiar refrain. Like similar groups before them, these attendees voiced great frustration over their inability to get at equipment assets and perform the most basic of routine maintenance tasks. This time, however, my response to all the venting was different from past workshops, in that I could flavor it with this classic Napoleonesque admonition: “Ability is of little account without opportunity.” The point of all this is that while we may know how to plan and schedule effectively, if we can’t get to the asset it is to no avail. Throughout the year, many non-controlled shutdown events will occur within a plant (i.e., operator-induced equipment/ line shutdowns, safety shutdowns, audit inspections, raw-material outages, etc.). There are also many short-term controlled shutdown events that occur on a daily basis (i.e., shift changes, product changeovers, break times, lunch times, manufacturing-target-completion shutdowns, etc.). Both non-controlled and controlled events represent a huge maintenance opportunity and the chance to introduce an Opportunity Based Maintenance (OBM) strategy and program.
LUBRICATION MANAGEMENT & TECHNOLOGY
For example, at one mining client’s site, when production would not give up its underground scoop-tram vehicles for basic lubrication, we identified an opportunity to introduce a “pit-stop” maintenance service program to service the lubrication needs of the vehicles during normal one-hour lunch periods—outside the drivers’ lunchroom. This “opportunity” resulted in handsome gains in both tram availability and productivity. The fundamental difference between traditional scheduling and OBM lies not only in the duration of the event, but how the work scope is identified. OBM takes advantage of very small time windows. Therefore, the Planner/Scheduler must scope out proactive work tasks that can be scheduled immediately, require just one technician and have job-plan durations suitable for scheduling in increments of 15 minutes, 30 minutes, 1 hour, on up to a maximum of 2 hours. The scope of work that can be included in an OBM approach will include: n n n n n n n n n
Manual lubrication Oil/filter change Equipment cleanup Laser alignment Utility-system leak checks Calibration Wear checks Oil-analysis sampling Belt replacements
OBM program setup requires maintenance and production departments to develop a communication strategy that will inform maintenance immediately when a non-controlled shutdown takes place—and to agree on an understanding about setting up pit-stop-styled maintenance tactics during short-term planned outages. If you have the ability, find the opportunity! As the comedian Milton Berle put it, “If opportunity doesn’t knock, build a door.” Good luck! LMT email@example.com

A key component of all types of applications, gears are used to transmit speed and power (torque) from one revolving shaft to another. They can change speed, torque and direction of rotation. Their major advantages as drives include the fact that they don’t slip, they’re able to carry high loads and they are compact in size. Figure 1 shows the simplest type, the spur gear.
Fig. 1. The simplest gear is the spur type. In this unit, the smaller gear is the “pinion.” The large one is the “bull.”
8 | LUBRICATION MANAGEMENT & TEChNOLOGy
PROFESSIONAL DEVELOPMENT SERIES
Referring to Fig. 1, note that the smaller gear in the spur unit is the pinion; the larger one is a bull gear (also known as a “driven gear”). Typically, gears are speed reducers. The amount of speed reduction is based on the teeth ratio of the pinion and bull gears. For example, if the pinion has 15 teeth and the bull (driven) gear has 75, the reduction ratio is 5:1. A pinion rotating 3000 rpm would result in the shaft of the driven gear to be 600 rpm. The rotation of the bull gear is opposite the rotation of the pinion. To have the same rotation between the pinion and bull gear, an idler gear—which has no effect on speed and torque— is inserted between the pinion and bull gear. Several terms are used to describe the mating action of gear teeth: 1. Pitch is the distance between a point on one tooth and the corresponding point on an adjacent tooth. It is the point on the tooth where rolling motion and the greatest force occur. Pitch circle is the circle formed by the point on each tooth at which meshing action is pure rolling. 2. Sliding motion that occurs above and below the pitch point, called respectively the addendum and dedendum of the tooth, can result in high wear. 3. The pure rolling at the pitch point results in an elastohydrodynamic lubrication regime characterized by a small solidlike lubricant film one micron or less in thickness. This small film does not prevent asperities (rough surface edges) from coming in contact with the pitch point, and causes
initial pitting along the pitch line of the mating teeth. This is perfectly normal unless the pitting spreads destructively to the dedendum and eventually throughout the tooth. 4. Clearance is the distance between the top of one tooth and the base of the tooth in the other gear. 5. Backlash is the distance between the back of one tooth and the front of the next mating tooth. Gear types and properties Gears are classified by shaft orientation. The most common type makes up the parallel shaft group, shown in Fig. 2. Some confusion can exist between double helical and herringbone gears: Most people consider them the same. In Fig. 2, though, notice that one of these gears has a strip in the middle and the other has continuous teeth. One definition holds that the double helical type has teeth slanting in opposite directions, while the teeth in the herringbone all slant in the same direction. Originally, that strip in the middle of the double helical was needed because of the manufacturing process. Eventually the process allowed all teeth to be continuous with no break in the middle. It should be noted that one of the major disadvantages of the helical gear is that it creates thrust along the shaft. This is eliminated by the use of herringbone (double helical) gears. Typical reduction ratios for parallel shaft gears do not exceed 10:1—and are more like 5:1. Table I summarizes the properties of parallel shaft gears.
Fig. 2 The parallel shaft group is the most common gear type.

PROFESSIONAL DEVELOPMENT SERIES
As illustrated in Fig. 3, the next group of gears, which have shafts at right angles, are divided into intersecting and nonintersecting types. Both bevel and spiral bevel gears have shafts that intersect at the centerline, whereas worm and hypoid gears have non-intersecting shafts with one below the centerline. The properties of right-angle shafts are illustrated in Table II. It should be noted that hypoid gears are used primarily in automotive applications: They’ve replaced spiral bevel gears in differentials, which results in a much more compact arrangement since the shafts can pass each other. They also produce high torque. Lubrication delivery systems Most gears are lubricated by splashing oil from a sump onto the gear teeth and bearings. Achieving the right level/ delivering the correct amount of lubricant is crucial. If the level is too low, you’ll find yourself dealing with lubricant starvation, increased wear, inadequate heat dissipation and foaming. Too much lubricant, on the other hand, may lead to churning, resulting in higher operating temperatures, a decrease in efficiency and greater foaming tendency. Typically, for parallel shaft and bevel gears at normal speed
(1000 fpm- 4000 fpm), the oil level ranges from completely covering the bottom teeth up to three times the depth of the bottom teeth—the most common being twice the depth of the bottom teeth. At very low speeds (< 1000 fpm), the level of immersion can be 3-5 times the tooth depth. Lubrication of worm gears is different. Worm gears come in three designs, each with its own lubrication approach: ■ Worm on top… the oil level is typically one-third of the wheel diameter. ■ Worm on the bottom… the oil level is up to 50% of the worm, which is the center of the meshing zone. ■ Worm at the side… half the wheel is immersed to at least the worm height. It’s best to adhere to what the OEM recommends for oil level during splash lubrication. The above levels are merely general guidelines. Be aware that there is a speed limitation on the use of splash lubrication. Speed is measured in meter/second or feet/minute (fpm) and calculated by multiplying the

circumference of the gear (π x diameter). For example, a 12” diameter gear, running at 1000 rpm, will have a speed of 3140 fpm (3.14 x 1 ft x 1000 rpm). With no design changes, a splash-lubrication system can usually operate up to 4000 fpm. By installing baffle plates and oil pockets, the speed can reach 11,000 fpm. At higher speeds, a pressurecirculation system is used. The two major types are dry sump (where the oil is stored outside the gearbox), or wet sump (where the oil is in the gearbox). In a pressure-circulation system, oil is sprayed directly at the teeth contact points. Lubricant selection The most important property for an oil used to lubricate enclosed gears is correct viscosity. The major variable in viscosity selection is the speed of the gears expressed in pitch line velocity, which is defined as speed of the gear in rpm times the circular pitch diameter in inches. The American Gear Manufacturers Association (AGMA) publishes viscosity recommendations based on pitch line velocity. Robert Errichello, a world-renowned expert on gear failure analysis, has developed the following simplified formula for determining the correct viscosity to use on enclosed gears:
Viscosity40 = 7000 √ V1
Keep in mind that Table III is only a summary of the most common viscosity grades for enclosed gears: It incorporates the old AGMA system, which has been changed. New tables no longer include the AGMA number. Many gearboxes still reflect the old system where viscosity grades were also expressed as a single digit number. Referring to Table III, we see the outdated AGMA number for ISO 220 gear oil is 5. To purchase the most up-to-date AGMA Classification System chart, go to www.AGMA.org. Once the correct viscosity has been determined, the oil type must be selected. Options include rust and oxidation (R&O) inhibited lubricants, synthetics, extreme pressure (EP) products and compounded oils. Table IV lists the types of oils used on enclosed reducer gearboxes.

■ The most common viscosity grade for both parallel shaft and right-angle intersecting gears is ISO 220 EP. When in doubt about using EP oil, go with it. ■ Worm gears experience high sliding, and the ring gear is typically bronze. EP additives are not recommended because of the additive attack on the yellow metal at high temperatures. ◆ Although new EP additives are less aggressive, in some cases such additives are not activated by the yellow metal and steel contact and serve no purpose in the formulation. ◆ Traditionally, worm gears were lubricated with oils compounded with synthetic animal fat to provide protection during the severe sliding that occurs. JULY/AUGUST 2011
PROFESSIONAL DEVELOPMENT SERIES
Correct viscosity is the most important property of an oil used in the lubrication of enclosed gears.
◆ PAOs have been successfully used in worm gears by providing protection during severe sliding without the use of EP additives. They also lower the temperature of the box and are completely compatible with mineral oils. ◆ PAGs are the lubricants of choice on new gearboxes as they provide the best efficiency. They’re also used in small, sealed-for-life worm gearboxes. If changing from another type of oil to a PAG, follow proper flushing procedures. PAGs are incompatible with mineral oils and PAOs. ■ Although hypoid gears are used mainly in automotive applications, they do have a few industrial uses. The severe sliding that occurs in these types of gears calls for very aggressive EP additives in high concentrations. Typical EP industrial oils will not provide the necessary protection for hypoid gears. This information is just a start: More details on gear oils can be obtained from product data sheets. NOTE: While a product data sheet provides useful information, the true test of a gear oil is how it works in the system.

PROFESSIONAL DEVELOPMENT SERIES
Hypoid gears call for very aggressive EP additives in high concentrations. Typical EP industrial oils won’t work for them. Gear failure modes
The major factors affecting gear life are load, environment, temperature and speed. Wear modes are summarized as follows: 1. Adhesive wear is caused by an inadequate lubricant film under severe boundary-lubrication conditions. This situation may require the use of higher-viscosity oil with an EP additive. Fig. 4. Destructive pitting is caused by surface overload conditions.
2. Abrasive wear is caused by hard particles in the oil gouging the gear teeth. The degree of wear is related to hardness and amount of particles present. Some have the misconception that gear oils don’t need a high cleanliness standard. That is incorrect: Gear oils should be kept as clean as possible. Very clean oil in a gearbox would be 17/15/13. 3. Surface fatigue is material failure caused by repeated surface and sub-surface stresses beyond the endurance limit of the metal that result in surface pitting. ◆ Initial pitting occurs at the pitchline where the lubricant film is very thin, resulting in asperity removal creating a smoother surface. This is perfectly normal and should be no cause for concern.
Fig. 5. Ridging on the side of a deformed gear tooth indicates a condition known as plastic flow, which is caused by severe overload. (This is NOT a lubrication-related condition.)
◆ Normal pitting occurs in the root part of the tooth (dedendum) and usually stabilizes. It occurs primarily when gear loads are close to the maximum and should be watched closely.
Conclusion Gears are an integral part of many manufacturing processes: A failure of a gear can have an enormous impact on production. These components must be lubricated properly and maintained to achieve long life. Oil analysis is an important predictive tool in monitoring gear wear. (This topic will be discussed in a later installment of our series.)
◆ Destructive pitting starts at the pitchline and progresses until the tooth is destroyed and is caused by surface overload conditions. This can be seen in Fig. 4. 4. Plastic flow is the deformation of gear teeth due to severe overload—this condition is NOT lubrication-related. It can be caused by unhardened teeth subjected to heavy loads (particularly shock-loading) causing surface material to be squeezed out at the tips of the teeth, shown in Fig. 5. (The ridging on the side of the tooth indicates plastic flow.) 5. Tooth breakage is primarily caused by severe surface overload, but also could result from severe surface fatigue that significantly weakens the tooth. 14 | LUBRICATION MANAGEMENT & technology

Lubricant performance can vary greatly between competing mineral-based and synthetic products. According to the innovators of Royal Purple, since quality differences can signiﬁcantly impact the cost of operating and maintaining equipment, your lube purchases can’t be effectively managed as a commodity: Lubricant excellence is paramount. The company notes that beneﬁts attainable across a broad population of rotating equipment from upgrading to Royal Purple lubricants include, among other things, energy savings greater than 3%, and a reduction in the need for equipment repair by at least 30%. Although Royal Purple products may cost more per gallon, an operation’s annual cost for lubricants changes little, due to greatly extended drain intervals and the elimination of oil changes associated with equipment repairs. Initiatives to reduce maintenance and improve equipment reliability often are time- and people-intensive. Royal Purple offers substantial improvements and savings simply through replacement of a product you already buy and use. It doesn’t get any easier than this.
Scalewatcher™ is a no-maintenance environmentally friendly descaler that does not change water composition. Scales and stains disappear gradually and completely, without further action required, guaranteed. The Scalewatcher products work by way of magnetic and electric ﬁelds and a continuously changing frequency. The process forces dissolved minerals such as calcium and magnesium to crystallize before mineral ions (the cause of hard scale) can settle on surfaces. This stops or reduces new buildup of hard scale, and because the water is better able to dissolve minerals, existing hard-scale layers are softened and eventually disappear. The Scalewatcher technology has been used by more than 250,000 satisﬁed customers worldwide. These products prevent corrosion in pipework; prevent settlement of zebra mussels in plants using sea or river water for cooling; reduce bacterial counts in cooling systems; cut water and energy bills; extend the life of water-using equipment (especially boilers); can be installed without plant shutdown; are maintenance-free; and last 20+ years.

Elemental Analysis Make sure this ‘exciting’ methodology is part of your predictive maintenance toolkit.
Jane Alexander, Editor with Ken Bannister and Ray Thibault
n element, in the simplest of terms, can be defined as a pure, naturally occurring chemical substance made up of a single unique type of atom. Elements in an oil can come from additives added to the virgin base stock, as well as from contaminants, wear metals or coolants that have found their way into the lubricant over its life cycle. Analyzing used oil for these known elements can help determine if the lubricant is still fit for use or requires change. Has the original additive package been depleted? Has the lubricant become contaminated and to what extent? Have wear metals begun showing up and are they a problem? 18 | LUBRICATION MANAGEMENT & TECHNOLOGY
Referencing used oil against a virgin oil sample can pinpoint which elements should and should not be present. Combined with an understanding of the industry and service for which the oil is designed (i.e., gearbox, internal combustion engine, hydraulic system, cooling system, etc.), this type of analysis can help detect where the unwanted elements may have originated and, in turn, predict impending mechanical failure. Elemental analysis is done through emission spectrometry. Today, the most commonly performed procedure of this type is atomic emission spectroscopy (AES). This test has been around for approximately 60 years. Originally a tool of the railroad industry for monitoring wear metals in diesel-engine oils, it’s now used on all types of equipment—and is a major component of comprehensive oil-analysis programs. Methodology In AES, the electrons in metal particles are excited into a higher energy state. As they revert to a lower energy state, they release light energy—which is inversely proportional to the wavelength and dependent on the atomic structure of the metal. Each metal will release energy at a specific, identifiable wavelength. The intensity of the light that’s measured relates to the concentration of the metal present in the oil sample and is reported in parts per million (ppm). Based on the spectrum produced by the excited particles (see Fig. 1), and the method used to excite them, up to 75 metallic elements in a lubricant can be identified. Inductively Coupled Plasma (ICP) and Rotating Disc Electrode (RDE) are the two methods used to excite the metal particles. In ICP, the elements are vaporized and excited by injecting a sample diluted with solvent into high-temperature argon plasma. The RDE method utilizes a high-energy electrode spark on a carbon wheel that rotates in the oil sample to excite the metallic elements.
LAB SPOTLIGHT Al
Fig. 1. Excitation of metal particles in an oil sample results in a spectrum that can be used to identify up to 75 elements.
Sn Pb Sn
Parameters Elemental analysis (i.e., AES) is a powerful test, but not perfect. One of its major drawbacks involves the size limitation of the metallic elements that can be detected. With RDE, the particle sizes detected are no larger than 8-10 microns. The ICP method detects metals no larger than 3-5 microns. Softer metals are easier to excite and can be detected at a higher size range than hard metals. Interestingly, while many labs are moving from RDE to ICP, both methods have advantages. RDE… ■ Detects larger particle sizes. ■ Detects up to 25 metallic elements. ■ No sample dilution is required. ICP… ■ Detects up to 75 metallic elements. ■ Is more accurate at smaller size ranges and used for quality control of additive concentrations in finished lubricants. ■ Newer, automated ICPs run samples faster.
Figure 2 depicts how elemental analysis data is typically documented in an oil-analysis report. It’s segregated into three major groups: Wear, Contaminants and Additives. Conclusion Elemental analysis—in the form of atomic emission spectroscopy—is a valuable predictive maintenance tool. Keep in mind, however, that it does have critical limitations (especially with regard to the size of particles it can pinpoint). While AES can identify early rubbing wear, it is unable to find large particles that lead to catastrophic failure. The lesson? Don’t depend solely on elemental analysis for particle detection. That said, in the September/October issue, we’ll examine Ferrography Testing.

DELIVERING THE GOODS
The Anatomy Of A Centralized Lubrication System
Dual Line Systems Dropsa’s DM-XOVER sub-base gives customers with existing traditional dual line delivery systems the option to easily switch over to a modular design concept and take advantage of numerous benefits that modularity offers, including reduced risk of contamination and less downtime. There’s no need to change pipe-work or fittings. This drop-in upgrade is supplied with the divider valves preassembled onto the sub-base plate along with a bracket to secure the base.
Ken Bannister Contributing Editor
irst introduced by the Farval Lubrication company, the Dual Line centralized delivery system (also known as a Twin-Line Parallel) was designed to accurately displace and move oil or grease over great distances from a single pumping station to as few as 20 lubrication points and up to many hundreds of points. The system’s heavy-duty construction and use of small-bore piping and tubing made it an ideal choice for automated lubrication in medium- and large-sized industrial equipment typically found in the steel, mining, pulp and paper, power-generation and petrochemical industries.
22 | LUBRICATION MANAGEMENT & TECHNOLOGY
The Dual Line lubrication system bears many similarities to the Positive Displacement Injector (PDI) or Single Line Parallel system, in that each metering valve—or point—can be set independently or easily adjusted during operation. This unique feature also enables additional injectors (lube points) to be added into the system at a later date, without the need to re-engineer the entire system. How the System Works As its name suggests, the Dual Line system employs two main lubrication lines that run in parallel from the pump to the last lubrication point through a series of lubrication delivery valves. Once the pump is activated, line pressure is built up on the pressure or delivery supply line to fire the lubrication point injectors while simultaneously venting the second return line back through a reversing valve to the reservoir. Dual Line injectors differ from Single Line injectors in that they do not use a spring arrangement to fire and load JULY/AUGUST 2011
the injector. Instead, they employ a dual-acting hydraulic spool valve set up to feed two separate lubrication points (one per each pressure cycle). Once an end-of-line pressure switch signals that a preset line pressure has been reached and all injectors have fired, the system has completed one pressure cycle—or a one-half lubrication cycle. The reversing valve is then actuated to its changeover position to allow the previous venting line to become the new primary pressure line and the process is repeated to complete one full-lubrication cycle. These systems can operate in manual mode with a pullhandle pump, as well as in full automatic mode. Pros & Cons Because Dual Line systems can be used with oil and grease, their engineering is not demanding—and can easily accommodate the addition or reduction of system points after they’ve been installed. As with Single Line systems, the adjustable injectors are easily tampered with and can lead to an over- or underlubrication condition unless they are access-controlled. A pressure-line failure is easily detected through a timeout switch located at the end of line. No secondary-line failure device is available. Users must perform system line integrity checks as part of their PM programs.

WE’RE BUILDING A TEAM...
e b u Meet Our L rz a t S
We love to learn about LMT readers, including what they do in the field of lubrication (and what they like about their jobs)! Here’s what our July/August Lube Star told us:
Mark L. Graham, CLS, CLGS, OMA Title: Technical Services Manager, Lubricants
O’Rourke Petroleum Products, based in Houston, TX Background: Mark has spent a total of 25 years in the
maintenance/lubrication arena (14 of them with O’Rourke, including three years in his current role). After graduating from college, this native of Bandera, TX, coached football and baseball in the public schools for awhile before moving into the solvent and chemical business. Why He Became A Lubrication Professional: Mark’s former employer also carried lubricants
in its line. He eventually found himself drawn to that side of the business and began pursuing both on-the-job and formal training in it. Today, he holds certifications as a CLGS (from NLGI) and as both a CLS and OMA (from STLE). Over the years, he says he’s been very fortunate “to work with and learn from some of the finest individuals in our business.” Mark gives props to John Wagner (of Shell Oil) and Bob Portwood (of Pacer Lubricants) for being tremendous resources in building his lube knowledge and skills. “With all their field experience,” he explains, “they had seen most everything that would or could go wrong. I could not have asked for better mentors.” What He Likes Most About His Work: Mark takes great pride in his work with O’Rourke
