12 rive ngineering ngineering recoendations Several drive selections can usually be made for a given application. onsideration life expectancy, space, speed, cost and similar factors ten suggest the better selection. Use the following recoendations as a guide when selecting roller chain drives. Horsepower ratings he horsepower ratings listed on pages -9 to -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 able 2, page -7. Stainless steel chain and other variations standard roller chain are also selected from the rating tables by applying the appropriate material or design variation factor from able 3, page -7. hain 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. his permits a larger number in the driver sprocket and results in smoother drive operation. for small sprockets he recoended minimum number for the small sprocket varies with operating conditions. he recoended minimums are: Very slow speed drives Slow speed drives Moderate speed drives High speed drives Hardened It is good practice to harden sprockets with 25 or less when applied to: Very low speed, heavily loaded drives High speed drives Large ratio drives brasive or corrosive conditions For additional information, consult Rexnord. hart Variations in chain speed due to chordal action hordal action he rise and fall each pitch chain as it engages a sprocket is termed chordal action and causes repeated chain speed variations. s illustrated by chart, chordal action and speed variation decrease as the number in the small sprocket is increased. hordal action becomes negligible when 25 or more are used and results in smoother drive operation. 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. for large sprockets he number in the large sprocket has an appreciable effect on the amount joint wear (or pitch elongation) that can be accoodated by the chain before it tends to jump or ride over the. his is illustrated by hart. Generally, a roller chain has reached its useful wear life when the elongation per pitch is in the range 2% to 3% pitch. s show in the chart, this would result in a maximum for the large sprocket. his suggested maximum can be exceeded by making a more conservative chain selection. When space limits the diameter the large sprocket, it may be necessary to select a smaller pitch, multiple strand chain to provide a sufficient number for the small sprocket. rive ratio he drive ratio is determined by the speeds 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 ten more economical than a large ratio, single-reduction drive. 7:1 RIO 7:1 RIO (WO RIVS) PRN SP VRIION = V2 - V1 X 100 V R = PIH RIUS OF SPRO WHL r = R X OS 180 = NUMR OF H N = RPM MINIMUM HIN SP r R 180 r R 180 V 1= 2πrN 12 V 2= 2πRN NUMR OF H IN SPRO MXIMUM HIN SP HORL RIS N FLL OF HIN = R - r HIN WR PR PIH IN % OF PIH Fig hart Variations in useful chain life based on pitch elongation elongation and and number in large in large sprocket sprocket HIN WR PR PIH IN % OF PIH LONGION PR PIH IN % OF PIH = 200 LONGION PR PIH IN INHS = 2 X P P = HIN PIH IN INHS = NUMR OF H IN LRG SPRO NUMR OF H IN LRG SPRO imensions and other engineering data are subject to change. ertified specifications ordered product furnished upon request.

13 Select relatively large diameter sprockets for 1:1 and 2:1 ratio drives, especially if required to operate on horizontal centers. his will assure adequate distance between the two spans chain and prevent them from striking as wear accumulates. his is particularly important for drives on long, fixed centers with the slack chain span on top. ROMMN NO ROMMN Fig Small pitch, multiple strand chains are generally more economical for large ratio drives on minimum centers. Large pitch, single strand chains are usually most economical for small ratio drives on long centers. enter distance centers must be more than 1/2 the sum the sprocket outside diameters to avoid tooth interference. suggested minimum center distance would equal the diameter the large sprocket plus half the diameter the small sprocket. rives so proportioned also assure the minimum suggested chain wrap 120 on the small sprocket d + d Fig hain tension o obtain maximum chain life, make provisions to maintain proper chain tension. Make an initial adjustment after approximately the first 100 hours operation to remove slack caused by initial elongation. hereafter, the frequency periodic adjustments is governed by operating conditions. Fig he simplest method adjusting chain tension is to provide for movement one shaft. his method is coonly used for drives operating from electric motors or internal combustion engines since they can be mounted on adjustable baseplates or slide rails. 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. he idler sprocket should have a minimum 17 and should be located adjacent to the driving sprocket so that at least 3 are in full engagement with the non-load-carrying span chain. If possible, provide enough adjustment the chain tightener to permit removal two pitches chain. ypical 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 fset links and twopitch fset assemblies can be supplied. Offset assemblies are recoended for high speed or heavily loaded drives. hain tension should be carefully maintained when the following operating conditions exist: Fixed centers Vertical or near vertical centers Shock or pulsating loads Reversals in direction rotation hain length When possible use a chain length with an even number pitches to eliminate the need for an fset link Fixed centers When sprocket centers cannot be adjusted, make a conservative drive selection by using a larger service factor than indicated. lso, provide good lubrication. Low speed drives Ratings are not shown in the horsepower tables for extremely low speeds. For operation at these speeds, select drives on a chain strength basis. he ratio ultimate chain strength to working load should be at least 6:1. rives that operate at varying speeds such as power takef drives from a torque converter, from an engine with a multispeed gear transmission, or from a constant horsepower, variable speed electric motor, should be selected on a chain strength basis. he ratio ultimate strength to maximum peak load should not be less than 6:1. he selection should be checked against the horsepower table for sufficient rating at the normal operating speed. rives 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 speeds involved. Preferred drive arrangements he drive arrangements illustrated below are desirable for optimum life the drive. he preferred direction rotation is indicated for each arrangement, although arrangements, and will operate satisfactorily in either direction.

14 rive ngineering Other arrangements hese arrangements are not generally recoended but they will give satisfactory service if carefully attended and chain tension is accurately maintained. Operating conditions he service factors listed in able 1 page -7 are for normal operating conditions. Increase these service factors to compensate for any the following conditions: Heavy starting loads Frequent starts and stops Lubrication inferior to method recoended Short or fixed centers Vertical centers, particularly if the small sprocket is in the low position wo or more driven shafts Periodic load variation in a single revolution Reversals drive rotation Inertia strains Large ratios Lubrication dequate lubrication is necessary for optimum drive life. general guide to the recoended method lubrication is indicated in the horsepower rating tables. hese recoendations are based primarily on chain speed. For complete lubrication data, refer to pages -45 and -46. Useful formulas Formulas for calculating horsepower, torque, chain speed, working load and similar values are given on page H-1. rive selection procedure Fig lthough horsepower and speed are the prime considerations for selecting a drive, the following information is also necessary: Source power Horsepower to be transmitted Size and speed driving shaft riven equipment Size and speed driven shaft pproximate center distance between shafts Relative position shafts Space limitations With this information the selection procedure is as follows: stablish the service factor Select a service factor from able 1, page -7, to compensate for the loads imposed on the chain by the type input power and the type 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 onditions above. stablish the material or design variation factor When a variation standard roller chain is being selected (such as stainless steel chain for corrosion resistance), refer to able 3 on page -7 and determine the appropriate variation factor. his factor compensates for either the design or material difference so that a selection can be made from the standard roller chain rating table. alculate the equivalent horsepower Multiply the horsepower to be transmitted by the service factor (and by the variation factor, if applicable). his product is the equivalent horsepower or the value on which the chain selection is based. Select a trial chain Standard roller chains are most coonly used and are selected from hart, page -5. Single strand chains satisfy most drive requirements; however, multiple strand chains are ten required for high speed drives, where space limits sprocket diameters, or where horsepower requirements exceed the capacity single strand chains. ouble-pitch chains are ten used for slow speed, comparatively low horsepower drives on long centers. Use hart, page -6, to make a trial chain selection. o 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 the small sprocket. he area in which the two lines intersect indicates the probable chain requirement. It is ten desirable to evaluate selections based on the next smaller or next larger chain size, especially if the point intersection is near the border an area. etermine the number for the small sprocket he 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 -9 to -43). In the column corresponding to the RPM the small sprocket, find the rating nearest to the equivalent horsepower. Follow this line horizontally to the left to find the number 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. he required table rating per strand is calculated by dividing the equivalent horsepower by the appropriate multiple strand factor from able 2, page -7. Now, refer to the horsepower rating table for the trial chain. In the column corresponding to the RPM 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 for the small sprocket. heck the small sprocket heck the bore capacity the sprocket selected, making sure it will accoodate the driving shaft. If the initial selection does not have adequate bore capacity, use a sprocket with larger number, or select a drive using the next larger pitch chain. etermine the drive ratio ivide the speed the faster turning shaft by the speed the slower turning shaft. imensions and other engineering data are subject to change. ertified specifications ordered product furnished upon request.

15 etermine the number for the large sprocket Multiply the drive ration by the number 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 its pitch diameter and the chain pitch. ncased drives require an additional 3" radial clearance. If sufficient space is not available, consider a smaller pitch, multiple strand drive. alculate exact center distance and chain length Formulas for these calculations are on page -8. Lubrication he methods lubrication shown in the horsepower rating tables are based primarily on chain speed; however, the relative position driving and driven shafts ten influence the method lubrication. Recoendations and complete lubrication information are given on pages -45 and -46. rive selection example Problem Select a roller chain drive for the following conditions: Source power Gearmotor Horsepower to be transmitted 10 HP Size driving shaft 2.438" diameter Speed driving shaft 100 RPM riven equipment ucket elevator uniformly fed Size driven shaft 2.938" diameter Speed driven shaft 42 RPM pproximate center distance 24.00" Relative position shafts On same horizontal plane Space limitations None Solution Service factor he service factor listed in able 1 on page -7 for a uniformly fed bucket elevator driven by a gearmotor is 1.0.

56 rive ngineering 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 service, and method lubrication influence the life chain. Many low-speed drives perform successfully with little lubrication, but where operating conditions permit, longer chain life will result from adequate lubrication. he primary purpose chain lubrication is to provide a clean film oil at all loadcarrying points where relative motion occurs. o effectively lubricate the chain joints, oil must be delivered to the spaces indicated in Figure he oil should be directed to the inside the lower span chain so that it will not be thrown f by centrifugal force before it penetrates the chain joint. INSI H ROLLR Factory Prelubrication WN H RS O H P Fig Laboratory tests and actual experience show that chain joint friction is greatest during the run-in period, the span time between drive start-up and the point at which the lubrication system begins to function effectively. o minimize joint friction during this critical period operation, Rexnord roller chains are factory prelubricated. Laboratory tests show that prelubrication reduces joint wear during the critical run-in period by approximately 50%. he result is longer operating life for the chain. Subsequent maintenance a clean oil film between all bearing surfaces is equally important for high operating efficiency. Selection the Lubricant rives operating at room temperatures should be lubricated with an S 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. emperature atmosphere surrounding drive, degrees Fahrenheit Petroleum oils should not be used to lubricate drive chains operating in temperatures above 300 F (149 elsius). Under certain operating conditions, chains operating in high temperature atmospheres can be effectively lubricated with colloidal graphite dispersed in a suitable volatile carrier. hese solutions penetrate the chain joints and, upon evaporation the carrier, leave a thin deposit graphite on the chain joint surfaces. his type lubricant may be applied by drip-feed or wick-feed oil cups. onsult a lubricant manufacturer for recoendations when chains are required to operate at temperatures between 300 F and 700 F (149 and 371 ). Suggested Methods Lubrication S... viscosity number 20 to to to to Several methods for lubricating chain drives have been developed, each fitting a particular range operating conditions. Horsepower, chain speed, and the relative position shafts are primary considerations. he various methods suggested and their range application are described below. Manual or drip lubrication may be used for open running drives (those enclosed by a safety guard) which operate in a non-abrasive atmosphere. hese methods should be confined to low horsepower drives operating at low chain speeds. he lubricant may be applied to the clearances between sidebars with a brush, oil can, or dripcup oiler. rip-cups are usually mounted on a pipe with drilled holes spaced to distribute oil between the sidebars in the lower span chain. bout 4 to 10 drops per minute are sufficient to lubricate very slow speed drives, while a minimum 20 drops per minute is recoended for higher speeds. he relative position shafts is not a factor when these methods lubrication are used. ath lubrication is the simplest automatic method lubricating encased chain drives and is highly satisfactory for low or moderate speeds. he chain dips into an oil reservoir to a depth about one-half inch, forcing the lubricant into the chain joints. Only a short length chain should run through the oil, preferably only that portion on the bottom the lower sprocket. he relative shaft positions illustrated below are recoended when oil bath lubrication is used: Fig Fig OIL LVL OIL LVL Fig OIL LVL imensions and other engineering data are subject to change. ertified specifications ordered product furnished upon request.

Forced lubrication is recoended for large horsepower drives, heavily loaded drives, high speed drives, or where oil bath or oil disc lubrication cannot be used. OIL LVL Fig Fig n oil disc mounted on the lower sprocket dips about one-half inch into an oil reservoir. he oil is thrown f the disc by centrifugal force, automatically lubricating the chain which is kept above the oil level. his method lubrication is ineffective at high speeds as well as at very low speeds.

58 rive ngineering rive Installation ccurate alignment, proper chain tension, good lubrication, and periodic inspection are required to obtain maximum chain and sprocket life. For safe installation chain and sprockets, careful attention should be given to the following instructions. aution: Shut f 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. s 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. he distance between shafts on both sides the sprockets must be equal.

76 onveyor ngineering ngineering Recoendations In keeping with modern machinery design, roller chains are widely used for conveyor service because 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. he ouble onveyor chains are similar to the drive chain series, differing principally in sidebar style. ompared 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 joint articulation. onsequently, different methods are used in selecting chains for conveyors than for power transmission service. he procedure for selecting conveyor chains is outlined on page -4. Use the following recoendations as a guide when selecting roller chains for conveyors. hain types hree general types roller chains are used for conveyor applications: Standard Roller chains with suitable attachments are usually applied where sprocket diameters are restricted and smoothness operation is essential. Most sizes are readily available in stainless steel for corrosive conditions. ouble onveyor chains are more economical than Standard Roller chains and are available with either standard diameter or large diameter rollers. hains with standard diameter rollers are furnished for vertical conveyors or for applications where the chain slides on the edge the sidebars. hains with large diameter rollers are recoended when it is advantageous to reduce the power required to operate the conveyor. Flat-top chains in numerous styles are available for transporting containers all types, small parts, packages, and countless other items through various processing operations. op-plates attached to the chain form the carrying surface. hain pitch lthough conveyor chains are usually selected on the basis ultimate strength, it is ten necessary to consider chain pitch. hain pitch may govern, or be governed by, the size the carrier or the attachment spacing. onsider short pitch Standard Roller chains, 35 through 80, for short conveyors or where smooth operation is required. For a given sprocket smaller pitch chains permit a large number sprocket ; hence, less chain speed variation. See hart, page -2. For longer conveyors, consider ouble 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 ngineering chains. onsult Rexnord for specifications. Multiple strand conveyors When two or more strands chains must operate abreast, strands are matched for uniform length and attachment location. ach 10-foot length is tagged to indicate the proper sequence assembly. s should be keyseated in line with respect to a tooth or tooth space to assure an equal distribution the load in all strands chain Fig -166 It is not necessary to couple the strands in numerical sequence unless more than one type attachment is used in variable spacing. Operating temperature Roller chains may be operated in moderately elevated temperature zones, as in baking and enameling ovens. he working factors listed in the table on page -4 may be used when the chain temperature is below 350 F. onsult Rexnord Industrial hain for operation at temperature above 350 F. Refer to page -9 for information regarding lubrication at elevated temperatures. hain joint bearing area hain joint bearing area is the pin diameter multiplied by the bushing length. lthough this value is not directly used in the chain selection procedure, it can serve as an indicator comparative wear life between two chains. For this reason, bearing area values are shown in the conveyor chain specification tables, pages -3 to -6. atenary tension and chain sag he formulas applying to the conveyor layouts on pages -6 and -7 do not consider catenary tension since most roller chain conveyors are designed to support the return span chain. However, for short conveyors, it is not uncoon or undesirable to permit the return run to hang free. Longer conveyors are sometimes designed so that the major portion the return run is supported, thus allowing the catenary tension in the unsupported section chain to act as a takeup. When the return run chain on a long conveyor is unsupported, calculate the catenary tension due to chain weight and add it to the chain pull so that the selection will be based on the total working load. atenary 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.

Numerous attachments are available to accoodate slats, crossrods, and other coonly used conveying devices. he procedure for selecting the roller chains listed in able 6 follows. Roller chain selection procedure Preliminary information lthough chain pull and speed are the prime considerations in selecting a roller chain for conveyor service, the following information is also required. ype conveyor onveyor speed, feet per minute (FPM) pproximate center distance between shafts, feet pproximate diameter and bore sprockets, Weight material to be conveyed, per conveyor foot ind material to be conveyed Weight carriers (slats, pans), per conveyor foot Size and spacing carriers ype attachment With this information, the selection procedure is as follows: Select the layout Refer to pages -6 and -7 and select the appropriate conveyor layout. alculate the approximate conveyor pull alculate the approximate conveyor pull from the formula accompanying the layout. Since a chain has not yet been selected, value W will include the weight slats, pans, or other carriers, and an approximate chain weight 2 per foot for each strand. lso, assume a takeup tension 40 for each strand chain. stablish the working factor Select a working factor based on the operating speed the conveyor. he factors listed below apply to evenly loaded, well lubricated chains operating in a clean, non-abrasive atmosphere, and in a normal temperature environment.

80 Roller chain selection procedure (cont.) etermine the minimum conveyor strength required Multiply the working factor by the approximate conveyor pull. he product is the minimum ultimate conveyor strength required. etermine the minimum chain strength required ivide the minimum conveyor strength by the number strands carrying the load. When the conveyor is designed to use two or more parallel strands chain the required chain strength should reflect the distribution 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 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 able 6 on page -4 and select a chain with an ultimate strength slightly greater than the minimum requirement just calculated. he size slats or pans, or the required spacing attachments govern chain pitch. Make sure that the chain selected meets both pitch and strength requirements. heck the chain selection Refer to the formula previously used and compute the actual chain pull, considering chain weight (able 6 on page -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. heck the result against the ultimate strength the chain selected. If equal to or greater than the minimum requirement, the chain selection is satisfactory. etermine the number in the sprockets Use sprocket pitch diameters listed for drive series ouble chains (pages -10 through -23) for determining the number in the desired sprocket for use with conveyor series extended pitch chains. If possible, use sprockets with 15 or more. Smoothness conveyor chain operation is dependent upon adequate in the driving sprockets, as illustrated in hart, page -2. alculate chain length and sprocket centers When the number in the sprockets is equal, calculate chain length from the formula: chain length, in pitches = + 2c P where c = center distance between shafts, P = chain pitch, = number per sprocket hain length should equal an even number pitches. Using the nearest even number pitches as value N, calculate the exact sprocket centers from the formula: = N P 2 where = exact sprocket centers, N = nearest even number pitches P = chain pitch, = number per sprocket When the number in the head and foot sprockets is unequal, chain length and exact sprocket centers are calculated from the formula on page -8. hain sag he amount sag in the slack span chain is calculated from the formula on page -2. Lubrication It is usually advisable to lubricate conveyor chains. See page -9 for methods and recoendations. alculate the conveyor horsepower requirement o calculate the horsepower required to operate the conveyor, use the formula in the appropriate conveyor layout, pages -6 and -7.

84 Lubrication Lubrication he primary purpose chain lubrication is to provide a clean film oil at all load carrying points where relative motion occurs. his is particularly important during the initial break-in period when the wear characteristics the chain are being established. onsequently, most chains are pre-lubricated at the factory unless otherwise specified. o be effective, subsequent lubrication must be directed to the bearing surfaces as shown in Figure etween the sidebars to the pin-bushing bearing surface Roller chains all types Inside the roller s a general rule, lubrication 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 the conveyed material must be avoided. Likewise, the presence lubricant in a very dusty or abrasive environment could be a deterrent to long chain life. In these cases, lubrication decisions must ten be based on actual experience. Selection the lubricant Fig onveyor and elevator chains operating at room temperature should generally be lubricated with a straight mineral oil S... viscosity number 30. Lower or higher ambient temperatures require oils with lower or higher viscosity numbers, respectively. he following operating conditions require special lubricants: levated temperatures Petroleum oils should not be used to lubricate conveyor or elevator chains operating in temperatures exceeding 300 F (149 ). Under certain conditions, chains operating in high-temperature atmospheres can be effectively lubricated with colloidal graphite dispersed in a suitable volatile carrier. he solution penetrates the chain joints and, upon evaporation the carrier, leaves a thin deposit graphite on the chain joint surfaces. he lubricant may be applied by drip-feed cups, provided agitation is used. onsult a lubricant manufacturer for recoendations when chains are required to operate at elevated temperatures. orrosion he effect unusual corrosion conditions can sometimes be reduced with special lubricants. onsult a lubricant manufacturer for a material that is not soluble in the corrosive element. High loads When chain joints are subject to high unit bearing loads, use an P oil. his type lubricant has an extreme pressure additive that helps maintain a cushioning film oil between joint components. Methods lubrication It is difficult and generally impractical to provide protective housings for chains applied to conveyors and elevators. hey are usually operated in the open and exposed to the material being conveyed. herefore, applying a lubricant is difficult under some operating conditions. Various methods are used to lubricate conveyor and elevator chains. he nature the surrounding atmosphere is the principal consideration in selecting the best method to use. lean atmosphere hains operating in a relatively clean atmosphere can be lubricated manually or by a semiautomatic method using drip cups. he lubricant may be applied manually with a brush or spout-type oil can to the spaces shown in Figure 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 chain. bout 4 to 10 drops per minute are usually sufficient to lubricate slowspeed conveyors. It will take about one hour to drop one ounce oil at the rate 10 drops per minute. tmosphere laden with lint or nonabrasive dust Where large volumes 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. his type lubrication can be made to operate automatically. brasive 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. hains operating in an abrasive atmosphere can ten 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 abrasive materials. o lubricate a chain with petroleum jelly or non-fluid greases, heat the lubricant until fluid. Ierse the chain and allow it to soak until air bubbles cease to rise, thus indicating that the lubricant has penetrated the chain joints. llow the chain to remain submerged until the lubricant is partially solidified to prevent the lubricant from draining out the joints when the chain is removed. efore relubricating, thoroughly clean chain to remove all dirt and abrasives.

108 s General Specifications G he standard sprockets used with Rexnord chains, both physical and dimensional, are based on sound engineering principles. hey reflect the practical experience gained from applying drives over the last century. Material and hardness materials and tooth hardness along with accurate machining, are as important to drive life as proper chain selection or adequate lubrication. Material and hardness have a strong influence on the rate tooth wear and, therefore, the maintenance optimum chain and sprocket interaction. he severity and frequency tooth loading, environment, and similar operating conditions form the basis for material selection. For example, the small sprocket is usually made higher carbon, more wear-resistant steel because its contact the chain more ten than those on the large sprocket. he frequency contact is in direct proportion to the speeds the driving and driven shafts. With these and other operating conditions in mind, the following standards have been established. Recoended Materials are indicated in the table below. Material and tooth hardness recoendations are based on chain speed, number, and operating conditions. When drives are designed for short-term operation, it may be desirable to specify a lower hardness than indicated in the table. hain speed FPM Up to 600 Over or less 26 or more 25 or less 26 or more Recoended material and hardness Normal operating conditions s Severe operating conditions n Medium carbon steel with an approximate hardness 170 rinell Medium carbon steel with an approximate hardness 170 rinell; or cast iron with a minimum hardness 183 rinell Medium carbon steel with hardened to 35 Rockwell minimum Medium carbon steel with an approximate hardness 170 rinell; or cast iron with a minimum hardness 183 rinell Medium carbon steel with hardened to 35 Rockwell minimum Medium carbon steel with hardened to 35 Rockwell minimum; or lloy cast iron Medium carbon steel with hardened to 35 Rockwell minimum Medium carbon steel with hardened to 35 Rockwell minimum; or lloy cast iron s Operating conditions are considered normal when drives are enclosed and adequately lubricated, or when open drives operated in a clean atmosphere with ample lubrication. n Operating conditions are considered severe when drives are subject to frequent heavy overloads, shock or pulsating loads, inadequate lubrication, or when open running drives operate in an abrasive or corrosive atmosphere.
