6 Engineering lass s rive Selection Introduction Engineering lass rive s are one of the most efficient and cost effective ways to transmit mechanical power between shafts. hey handle large working loads in the slow to moderate speed range, have very small energy losses, and are generally inexpensive compared with other methods of transmitting power between rotating shafts. Successful selection involves following several simple steps involving algebraic calculation and the use of Horsepower, Service actor tables and/or working load calculation. or any given set of drive conditions, a number of possible chain and sprocket combinations are possible. he designer therefore, should be aware of several selection principles which, when applied correctly, help to balance overall drive performance and cost. he purpose of this section is to help designers make selections that meet the requirements of the drive, and are cost efficient. General rive Selection rinciples a) he recommended number of teeth for the small sprocket is 12. he minimum which should be used is 9. Smoother operation is achieved with more teeth. b) Speed ratios should be 7:1 or less (optimum) and never more than 10:1. c) he minimum wrap of the small sprocket is 120 degrees. General rive Operating rinciples a) Lubrication: separating wedge of high quality oil formed between the operating joints protects chains from rapid wear out due to metal to metal contact and if supplied in sufficient volume also provides effective cooling and impact load damping. Effective lubrication is the single most effective way to improve chain performance and prolong life. he chain should be protected against moisture and kept free of contamination. High quality nondetergent petroleum based oil is recommended. Heavy grease is generally too stiff to penetrate chain joints effectively. he following indicates the recommended viscosity for a given temperature: b) c) d) SE20: 20º 40º SE40: 100º 120º SE30: 40º 100º SE50: 120º 140º lignment: ccurate alignment of shafts and sprockets helps provide uniform distribution of loads across the entire width of the chain and contributes to optimum drive performance. irection of ravel: or offset bar chains used in power transmission service (i.e. drives), the narrow end should face the smaller sprocket on the tight side. Note that this is not always the best running direction for offset side bar chains used on conveyors. Sprockets: Hardened tooth sprockets are recommended. equired Information for rive Selection a) ype of input power (electric motor, internal combustion engine with mechanical or hydraulic drive), and type of equipment to be driven. b) mount of horsepower required to provide sufficient power to the driven shaft. ull load speed of the fastest running shaft (rpm). 8 c) d ) e) f) g) esired speed of the slow running shaft (i.e. the speed ratio). NOE: If speeds are variable determine the horsepower to be transmitted at each speed. iameters of the driver and driven shafts. enter distance of the shafts. NOE: If this distance is adjustable determine the amount of adjustment. Note the position of the drive and any space limitations that might exist. hese space limitations usually limit the diameter of the large sprocket and may require the speed reduction (or speed increase) be accomplished in more than one (1) drive ratio. onditions of the drive. It is advisable to consult with Hitachi engineering personnel when unusual conditions such as widely fluctuating loads, temperatures, or severely abrasive or corrosive environments exist. bbreviations Used in Equations N: of teeth on the large sprocket. n: of teeth on the small sprocket. : Speed in revolutions per minute (rpm) of large sprocket. r: Speed in revolutions per minute (rpm) of small sprocket. S: Linear Speed in feet per minute (fpm). : Shaft center distance in chain pitches. H: Horsepower of the drive motor or engine. S: Service actor H: esign Horsepower : Speed actor : alculated chain tension. Selection by alculating ension he method for selecting Engineering lass rive s in this catalog will involve: a) b ) c) alculating the design horsepower (H) based on the motor or engine capacity and the drive conditions. etermining the calculated chain tension from the design horsepower and chain speed. omparing the calculated chain tension () to the rated working load of the selected chain and in some situations to a value equal to 15% of the selected chains average ultimate strength. Most Engineering lass rive s operate at relatively slow speeds. he rated working load values found in the dimensional tables in this catalog are based on maintaining a maximum bearing pressure between the pin and bushing of 3,500 pounds per square inch (psi). his means that if the calculated chain tension in the drive is equal to or less than the selected chain s rated working load we will be operating at or below the optimum pin/bushing bearing pressure of 3,500 psi and we can expect successful chain performance. e note however that often chains can be operated successfully in excess of the rated working load limit. he applications that lend themselves to successful performance in this situation are slow speed (less than 50 ft/min), well lubricated chain drives. In this case we may operate the chain at a calculated chain tension () up to 15% of its average tensile strength. hen selecting chains by this criterion confirm the selection with Hitachi engineering personnel.

7 rive Selection Step 1: etermine the esign Horsepower (H) H = Motor H x S S (Service actor) is based on the type of input power and classification of the expected shock loading in the application. Use the table below to determine an appropriate S. lass of riven Load Uniform Moderate Heavy Internal ombustion Engine with Hydraulic rive Example: 25H electric motor which will operate with moderate shock loading has a H = 25 x 1.3 = 32.5 thus H = 32.5 Step 2: alculate Expected Linear Speed egin by assuming the recommended 12 tooth small sprocket and make a preliminary selection of chain pitch from the rive dimensional data shown in the preceding pages. It is not important that the selection be correct at this point. Use the following formula to determine linear chain speed (S): S = ( x r x n) / 12 Example: hoose a 12 tooth sprocket (n) with an input speed of 15 rpm (r) and estimate a chain pitch of 3.5 () we get: S = (3.5 x 15 x 12) / 12 = 52.5 fpm Step 3: etermine the alculated ension () = [H x 33,000) / S] x (Speed actor) can be determined from the table below: Linear Speed (fpm) ype of Input ower Electric Motor or urbine actor Internal ombustion Engine with Mechanical rive Example: rom the example we have been using since the linear chain speed is 52.5 fpm we would specify a speed factor of 1.2. alculated tension () = [(32.5 x 33,000) / 52.5] x 1.2 = 24,514 lbs. Step 4: etermine the equired ensile Strength or chain speeds less than 100 fpm, after applying the appropriate speed and service factors as shown above, we may operate a chain with the calculated chain tension () at 15% of the verage ensile Strength. equired verage ensile Strength = / 0.15 Example: In the example we have been using the required average tensile strength would be 24,514 /.15 = 163,426 lbs. Step 5: onfirm and/or eselect Size Now we must verify our preliminary selection is correct. If it was not sufficient we need to modify our chain selection so that the combination of itch and verage ensile Strength (S) meet the requirements of the equation as shown in Step 4. Example: eturning to our example we note that our 3.5 pitch chain is H238 which has an average tensile strength of 140,000 lbs. Since this strength is less than required S of 163,426 lbs. we must make another selection. e note that increasing pitch will increase linear speed and therefore reduce calculated chain tension, however, we might be limited by the diameter of the sprocket. e therefore will consider two larger pitch chains, H1242 and H1245. irst, we check H1243 ( = S = 140,000 lbs.) S = (4.063 x 15 x 12) / 12 = 60.9 fpm = [(32.5 x 33,000) / 60.9] x 1.2 = 21,133 lbs. equired S = 21,133 /.15 = 140,866 lbs. H1242 is close, but does not satisfy the requirement. Next, we try H1245 ( = S = 170,000 lbs.) e don t need to calculate this based on a 12 tooth sprocket since it will obviously be satisfactory, however, can we use a smaller sprocket? Let s try 9 teeth: S = (4.073 x 15 x 9) / 12 = 45.8 fpm = [(32.5 x 33,000) / 45.8] x 1.0 = 23,417 lbs. (note the speed factor changes). equired S = 23,417 /.15 = 156,113 H1245 with a 9 tooth sprocket does satisfy the requirements of Step 4 and may be selected. e would recommend that the largest number of teeth up to 12, which can be accommodated by available space, be specified. Note that it was possible to make H1242 or perhaps H238 work as well by increasing the number of teeth on the small sprocket. Sometimes much trial and error is required to get the best possible combination of chain pitch and number of teeth in the small sprocket to satisfy space limitations. inal Notes: he above method selects a chain based on chain strength. If the user desires less replacement over a more economical selection rather than comparing the calculated chain tension () to the S, the user may compare the calculated chain tension () to the rated working load given in the dimensional tables. his will select a chain with a larger pin diameter and will require less frequent replacement due to 9 wear out (i.e. elongation).

22 Engineering lass s onveyor Selection Introduction variety of Engineering lass s are available for conveyor or elevating service. n accurate assessment of the basic operating conditions and an understanding of the type of materials to be conveyed will determine the selection of an appropriate conveyor type. fter the above is determined we can then get down to the business of selecting an appropriate chain size. In general we classify the materials to be conveyed and their described capacities in two ways: 1. Unit Materials: 2. ulk Materials: apacity described in ieces er Hour. apacity described in ons er Hour. Unit materials are therefore objects like boxes, cars, V sets, etc.., while bulk materials would be products of sand, gravel, powdered sugar and the like. onveyor ypes here re Eight General ypes Of onveyors arrier onveyor 2.

Material load is directly carried on the chain. 2. Slat onveyor: wo or more strands of oller onveyor s are used to support slats mounted to chain attachments. Materials are carried on slats. Material load is carried directly on the chain. 3. usher onveyor: ypically two or more strands of oller onveyor, Steel ushed, elded Steel or ast ombination s are used with pusher type attachments. Materials roll or slide on support rails and is not directly carried on the chain. 4. ross ar onveyor: wo strands of oller onveyor connected by cross bars that can be arranged in a variety of chain paths are used for this type conveyor. roduct typically hands from the cross cars and load is carried directly on the chain. Sometimes hollow pin chains are used for this purpose as well. 5. rolley and ow onveyor: rop orged ivetless or ar Loop s are used in overhead trolley type conveyors and special bar pin chains are used for infloor towveyors. Material load is carried by rails or tracks in the floor rather than the chain itself. ulk Material Handling 6. Scraper light onveyor: ypically two strands of oller onveyor, Steel ushed, elded Steel, ast ombination, rop orged ivetless, or ar in s are used with scraper flights that convey bulk materials in a trough. he chains are located outside the trough. Material load is carried in the trough rather than directly on the chain. 7. rag onveyor: One or more strands of Steel ushed, elded Steel, elded Steel rag s, ast ombination, rop orged ivetless, or ar in s operate as plain chain in the case of elded Steel rag s or with drag flights mounted to the chain. rag onveyors are distinguished from scraper conveyors by the fact that they operate in the trough with the bulk material rather than on the outside. s with rollers are not recommended for drag conveyor service. 8. pron onveyor: wo or more strands of oller onveyor s with pron pans mounted to attachments are used to convey bulk materials. Sometimes outboard rollers with or without bearings are specified to reduce friction and therefore chain tension. If the conveyors are wide, through rods are specified to provide additional support. Selection onsiderations he first step in onveyor selection is to assess the operating conditions and the material to be conveyed in order to determine the type of conveyor to be used. oller onveyor s are best used in relatively clean environments with the chain carrying the load directly so that friction reducing rollers can lower chain tension and power consumption. ollerless chains such as steel bushed, welded steel or others are better when the loads are supported by rails or troughs in dirty operating conditions where such debris can cause rollers to seize and not function correctly.

26 Engineering lass s onveyor Selection Selection Examples Example #1: Horizontal Unit onveyor Supplied Information: Slat onveyor to move finished V sets from packaging line to the shipping floor V set is packaged in an 18 x 18 x 24 high box ox eight: 400 lbs each Operating Speed: 125 ft/min Sprocket enters: 75 ft Infrequent Moderate Shock Loading 16 Hour Operation in lean onditions Slats: 1/4 x 24 Long 12 ooth Sprockets are Specified Step 1: etermine asic equirements unit conveyor in clean operating conditions suggests the use of 2 strands of oller onveyor with K2 attachments to bolt the slats on. Slat weight will be approximately: Slat eight=1/4in x 24in x 12in/ft x.2833 lbs/cubic inch Slat eight = 20.4 lbs/ft of conveyor Material eight is estimated by: of boxes on onveyor=75ftx12in/ft/18in box=50 eight of 50 boxes = 50 x 400 = 20,000 lbs eight per foot of conveyor (M) = 20,000 lbs / 75 ft M = lbs/ft of conveyor. o estimate the required chain weight we note the following: Slat weight + Material eight on 75 ft of conveyor is: ( ) x 75 = 23,055 lbs. Estimate rolling friction coefficient of.16 from able 3 we get: 23,055 x.16 / 2 strands = 1,844 lbs of tension per strand. Since 1,844 lbs. is a relatively low tension we estimate the weight on the lower side of what is shown in able 1... e ll estimate 5 lbs/ft. e can now estimate eight of and Slats per foot of conveyor by the following: = (5 lbs/ft x 2 strands) = = 30.4 lbs/ft of conveyor e estimate rolling friction coefficient to be.16 based on a lubricated roller. hus f =.16 rom able 10 we find the service factor S by: S = 1.0 x 1.2 x 1.0 x 1.1 S = 1.32 ased on chain speed of 125 ft/min if we use a 12 tooth sprocket we note the speed correction factor: S = 1.05 rom able 8 since we are using 2 strands of chain we determine the number of strands factor as: NS = Step 2: alculate onveyor ull e now use the onveyor ull formula for the horizontal conveyor on the preceding pages as follows: = (2.1f+Mf) x +J* Note J=0 in this case = [(2.1 x 30.4 x.16) + (266.6 x.16)] x 75 = ( ) x 75 = (52.9 x 75) = 3,968 lbs. Step 3: alculate esign onveyor ull he esign onveyor ull () is given by: = x S x S x NS = 3,968 x 1.32 x 1.05 x 1.02 = 6,600 lbs. Step 4: alculate ension he calculated ension () is given by: = / otal of Strands = 6,600 / 2 = 3,300 lbs. Step 5: Select and ecalculate ension () rom the dimensional tables on page 12, 83 has a rated working load of 3,650 lbs, a 2.0 dia. roller and weighs 9.4 lbs/ft with a K2 every pitch. ecalculate.. and as follows: = (9.6 x 2) = 39.6 = [(2.1 x 39.6 x.15) + (266.6 x.15)] x 75 = ( ) x 75 = 3,938 lbs. = 3,938 x 1.32 x 1.05 x 1.2 = 6,550 lbs. = 6,550 / 2 = 3,275 lbs. Since the calculated chain tension of 3,275 lbs is less than the rated working load for 83 we can accept this selection. Step 6: Verify oller/ushing earing ressure if is olling Since we have selected a oller onveyor we need to check the roller/bushing bearing pressure as follows: Load er oller = (M+) / [(1/2 / itch) x Num. of Strands] Load er oller = ( ) / [(12/4) x 2] Load er oller = / 6 = 51 lbs. earing rea = ushing O x (Inside.063) earing rea = (.875) x ( ) = 1.09 Square inches earing ressure = Load er oller / earing rea earing ressure = 51 / 1.09 = 46.8 psi e refer to the dimensional tables and note that the bushing and roller are both carburized steel. rom able 11 (page 27) allowable bearing pressure is 750 psi. s the calculated bearing pressure of 46.8 is less than 750 psi the selection of 83 is verified.

27 onveyor Selection Example #2: Inclined Scraper light onveyor Supplied Information: ulk Material ituminous oal slack dry. onveyor apacity: 150 ons/hr Operating Speed: 100 ft/min otal Lift: 30 ft Sprocket enters: 50 ft Infrequent Moderate Shock Loading. 24 Hour Operation in irty onditions Steel rough : 24 inches verage depth of oal: 6 inches Scraper lights: 5/16 x 12 x 23 long, 22.8 lbs. ea Step 1: etermine asic equirements n appropriate chain type for a scrapper flight incline conveyor when the chain does not run in the material might be 2 strands of a oller onveyor with G19 or G29 scraper flight attachments. Since we are traveling up an incline the roller type chain will help reduce the power required. irty conditions may prevent the use of effective lubrication so we will base our selection assuming no lubrication for the chain. inally, we note that in this bulk material conveyor the chain does not directly carry the conveyed load, therefore, there will be no need to check the allowable roller/bushing bearing pressure. G19 attachments are available in 9 24 pitch chains. G29 attachments are available in 4 or 6 pitch chains. If we tentatively select a 9 pitch 925 chain we can calculate the estimated weight of the chain attachments and flights as follows: and attachments = 9.8 lbs/ft. x 2 strands = 19.6 lbs/ft. Scraper flights weigh 22.8 x (12/9) = 30.4 = = 50.4 lbs/ft Material weight (M) is determined by: M = [33.3 x apacity (tons/hr)] / conveyor speed (ft/min) M = (33.3 x 150) / 100 M = 50 lbs/ft e estimate the rolling friction coefficient to be fr =.14 since 925 has a 3 inch diameter roller which will not be lubricated (see able 3 page 25). he sliding friction coefficient for bituminous coal in a steel trough from able 4 (page 25) is fs=.50 rom able 10 (page 27) we find the Service factor by: S = 1.0 x 1.2 x 1.4 x 1.2 S = 2.02 rom able 9 (page 27) if we specify a 12 tooth sprocket we determine the speed correction factor as: S =.99 rom able 8 (page 26) since we are using 2 strands of chain we determine the number of strands factor as: NS = 1.2 Since the conveyor is inclined it will be useful to determine the sine and cosine of the incline angle: sinu = 30 /50 cosu = 40 / 50 sinu =.6 cosu =.8 Step 2: alculate onveyor ull e now use the onveyor ull formula for the incline conveyor on the preceding pages as follows: =[(Mf)cosu+(f)cosu+Msinu+sinu] + [(f)cosusinu]+j J = ( x H ) / rom able 7 we note that = 14 for coal and thus: J = (50 x 6 x 6 ) / 14 J = 129 lbs. Now we determine = [(50)(.5)(.8)+(50)(.14)(.8)+(50)(.6)+(50)(.6)] (50)+ [(50)(.14)(.8)(50)(.6)] (50)+129 = [ ] (50) + [5.630] (50) = 4,280 1, = 3,189 Step 3: alculate esign onveyor ull he esign onveyor ull () is given by: = x S x S x NS = 3,189 x 2.02 x.99 x 1.2 = 7,653 lbs. Step 4: alculate ension he calculated ension () is given by: = / otal of Strands = 7,653 / 2 = 3,827 lbs Step 5: Select, ecalculate ension () rom the dimensional tables we note that our tentative selection of 925 has rated working load of 4,150 lbs. which is greater than the calculated value of 3,827 lbs. so that 925 is a satisfactory selection. If we determined that the sprocket is too large for this application and that a 6 inch pitch chain with an 11 ooth sprocket was required we can check the suitability of 1131 with G29 attachments every 6 inches as follows: =(( ) x 2) + (22.8 x (12 / 6)) = = 76 lbs / ft M = 50 lbs/ft;s=2.02;s=1.03(see able 10) and NS=1.2 = [(50)(.5)(.8)+(76)(1.4)(.8) + (50)(.6)+(76)(.6)](50)+ [(76)(.14)(.8) (76)(.6)] = [ ](50) + [ ](50) = [5,205 1, ] = 3,221 lbs. = 3,221 x 2.02 x 1.03 x 1.2 = 8,042 lbs = 8,042 / 2 = 4,021 lbs. Since the calculated chain tension (4,021 lbs) is less than the rated working load (5,900 lbs) for 1131, this chain is suitable. e note that we could select a lighter 6 inch pitch chain such as 625 without additional calculation since it s rated working load is 4,150 lbs. he scrapper flight attachment is not standard, but can be designed. 29

28 Engineering lass s onveyor Selection onveyor Useful Information asic onveyor Layout akeup Loading rea ravel ischarge End Support ail ail Sprocket eturn ail Head Sprocket rrangement ower should be supplied to the head sprocket (discharge end) whenever possible to avoid high loading on both the carrying and return side. his will reduce the rate of chain elongation. Sprockets e recommend using the largest sprocket diameter that space will permit to minimize speed variations and pulsation caused by chordal action. Speed variations on sprockets with few teeth result from the difference in the chains radial position from the shaft centerline when a tooth or a tooth pocket is top dead center. Since the shaft turns at a constant speed a larger radial distance will speed up the chain and a lesser radial distance will slow down the chain. he fewer the number of teeth the greater the speed variation. his effect becomes negligible at approximately 18 teeth. or large pitch conveyors a compensating rive arrangement can be designed to vary the head shafts rotational speed to compensate for the effect of chordal action. Hardened eeth for sprockets are recommended particularly if there are fewer than 15 teeth. Match Sprockets hen a double strand chain conveyor has slats, flights, apron pans, or other parts that connect the two chains rigidly together, both head shaft sprockets should be matched. his can be done by specifying that the sprockets be keyed on the centerline of the tooth. e also recommend that on the tail shaft one sprocket be keyed and one sprocket be allowed to turn freely between set collars for automatic repositioning of the teeth if uneven chain wear occurs. onveyor Length Unusually long conveyor lengths can result in pulsation due to the chain s elastic properties. If this occurs, it may be necessary to use two conveyors with a transfer point or additional drives ake Up ension he correct amount of take up tension that should be applied is the minimum amount that allows for smooth action over the tail sprocket. s a guide this usually amounts to approximately.5% 2% of the chain s verage Ultimate Strength. Matched Strands Multiple strand conveyors often require matched and tagged chains. In this case each strand will be measured and matched so that adjacent strands are all within of each other in length. ight and Left Hand Strands On dual strand chain conveyors when the attachments are not symmetrical it is often necessary to order right and left hand chains. In many applications the cotter pins must face inside to avoid interference with rails on angle tracks. his can create asymmetric situation even though the attachments are symmetrical. Supports onveyors over 15 feet in length need to be supported on the return side to avoid pulsations, chain whip, or elongation causing excessive sag to strike adjacent conveyor components. return rail or idler sprocket is used for this purpose. Lubrication Effective lubrication is the single most important maintenance practice that can be done to extend chain life, reduce power consumption, and assist in smooth running troublefree service life. High quality nondetergent oils should be used. In some cases chain can be lubricated with grease through a fitting mounted on the chain pin (diameter should be at least in this case) or less frequently through a bushing lubrication hole (ollerless Steel ushed or elded Steel s). or oller onveyor s carrying large loads it may be best to fit the roller with a sealed roller or ball bearing to minimize friction and extend chain life. Hitachi engineering personnel are available to assist with lubrication guidance for specific applications. alculating Horsepower H = ( x S) / 33,000 = Maximum ension (lbs) S = Linear Speed H = (orque x rpm) / 63,000 orque is in inchpounds 30
