3. Calculate Design Horsepower: Motor HP x ServiceFactor, or normal running HP x Service Factor.4. Determine Chain Size and Smaller (Usually the Driv-er) sprocket number of teeth: Refer to “RecommendedSmaller Sprocket” table on page PT12--30, PT12--31.Start at column that is at or above the calculated designHP. Trace down to the row that includes the RPM of thefaster (Usually the Driver) shaft. The chain pitch andsprocket No. of Teeth are listed at this intersection.5. Calculate Drive Ratio: Faster shaft Rpm divided beSlower shaft RPM.6. Determine Size of Large Sprocket: Multiply smallersprocket No.teeth by ratio. Select Closest stock availablesprocket.7. Calculate Chain Length “L”:

L = 2c + 1.57. (D + d) +(D – d)2

4cWhere: D = Pitch dia. large sprocket, (see page PT12--44)

d = Pitch dia.small sprocket,(see page PT12--44)c = Proposed center distance

(Accuracy is within .15% chain length)Divide chain length (inches) by chain pitch to determinenumber of pitches in the chain. Good practice is to use aneven number of pitches, including connecting link.

SELECTIONSELECTION EXAMPLEA chain drive is required for a tumbling barrel for metalstampings. The barrel is to run at 24 RPM from a speedreducer output of 77 RPM. Center distance is 50”. Inputpower is from a 5 HP electric motor. Starting loads areheavy, peak loads and overloads are frequent.

1. Service Factor: Class of service is not listed in table,so refer to Class Description. Class C is appropriate. Ser-vice Factor Table shows 1.5 Class C driven by an electricmotor.

2. Design HP: Motor HP x S.F. 5 x 1.5 = 7.5 Design HP.

3. Chain and Small Sprocket Size: Refer to the 7-1/2 HPcolumn of the Easy Selection Table. Trace down to therow that includes 77 RPM, “71-80 RPM”. No. 100 chainand sprocket with 15 teeth is shown: select 100BTL15.

4. Drive Ratio: 77/24 = 3.21:1.

5. Large Sprocket: 15 x 3.21 = 48.15. Select a 48 toothdriven sprocket, 100BTL48, which is a stock size.

6. Chain Length:

L = 2(50)+ 1.57(19.113+ 6.013)+(19.113-6.013)2

4x50

L = 140.31” (No.100 Chain has 1-1/4 or 1.25” Pitch)Length in pitches = 140.31/1.25 = 112.48 pitches.Choose 112 or 114 Pitches of chain, including Conn Link.

7. Verify that sprockets will fit shaft sizes.

DESIGN NOTESSmall Sprocket Size: The higher RPM and the fewer thenumber of teeth on the small sprocket, the greater thewear.

This leads to some general guidelines:

¯ Use at least 17 teeth sprocket for 100+ RPM.

¯ Avoid high ratios that require very small sprockets

Lubrication: Chain drives must be lubricated and keptclean. The most effective method to accomplish this is touse an oil-tight chain guard with an oil sump. Manual lu-brication is effective on slower speed drives, but exposureto dirt and contamination will be a problem for the drive.

Design Refinement: The “Easy Selection Method” is agood starting point for further design refinement, if de-sired. Refer to the Chain HP Rating Tables on the follow-ing pages for more precise ratings. also refer to “SlowSpeed Drives” which follows this section.

SLOW SPEED DRIVESWhere linear speed of the chain is under 100 fpm andloading is uniform, roller chain drives may be selected onthe basis of chain pull rather than horsepower rating. Thisoften results in significant savings.

When chain length is more than 50 pitches, the maximumapplied load may be as great as 1/7 of the ultimate tensilestrength of the chain for speeds below 50 fpm to 100 fpm.

Unusual load variations of peak loads require other meth-ods of determining the maximum applied load.

Chain pull may be calculated by the following formula:

Chain Pull (lbs.) =Design hp x 126, 000rpm x pitch diam.

Table below offers a simplified method of determining al-lowable chain pull for slow speed drives. The table alsoshows revolutions per minute for a given pitch diameter at50 and 100 feet per minute. Average tensile strength forall popular roller chain is given on PT12--45.

Note: Smaller sprockets can be used on slow speed drives asthe effects of chordal action are not pronounced. However,small sprockets of fewer than 9 teeth should be avoided.

MULTIPLE STRAND CHAIN DRIVESSingle Strand drives offer cost and availability advan-tages, and are more easily assembled. Multiple stranddrives can be used to solve design problems of greaterHP capacity or space constraints. For multiple stranddrives, divide the calculated Design HP by the factors be-low, and select from the ratings for single strand drives:

Tensioner Frame, Idler SprocketsProper chain tension is necessary for normal life expec-tancy. It’s also a prime consideration for the efficient, quietoperation of the drive.

The tensioner frame shown below provides an economicalmeans of locating an idler sprocket on a 1/2″ diametermachine bolt or a 5/8″ diameter spacer. Frame can bemounted in several positions on surfaces either parallel orperpendicular to the chain, suitable for either conventionalor cantilever mounting.

CHAIN TENSIONER FRAME,P/N 102050This formed steel frame has mounting holes inthe bottom and one side so it can be mounted inseveral positions on surfaces parallel or perpen-dicular to the chain. Included is a 5/8″ O.D.sleeve and a 1/2″ diameter machine bolt to usewith 1/2″ and 5/8″ bore idler sprockets.

Spacer washers may be used to obtain thechain clearance required. ldler sprocket tablebelow shows minimum space required for chainclearance. Part Number 102050, WT. .73 lbs..

Custom TAPER-LOCK SprocketsNon-stock or special TAPER-LOCK sprockets may befabricated from stock TAPER-LOCK hubs and A-Platesprockets rebored to fit the hubs. This provides the capa-bility for fabricating sprockets with larger bore capacity, ornumber of teeth that are stocked as A-Plate but notTAPER-LOCK. This operation can be done on location, orsupplied by DODGE, price on application.

DODGE TAPER-LOCK hubs are available in three types:S, K and W/WA. All are of quality steel bar stock or forg-ings, easily welded, and ready to accept TAPER-LOCKBushings. For more detailed information and dimensions,refer to Bushings/Hubs section of this catalog.

Installation, MaintenanceInstallation of Roller Chain Drives

Shaft Alignment—Shafts must be parallel. The use of aspirit level is recommended to make sure shafts are hori-zontal; then, if the distance between the shafts are equalon both sides of the drive, the shafts are parallel. Shafts,bearings and supporting structure should be suitable tomaintain this alignment.Sprocket Location—Locate each sprocket as close aspossible to a bearing.Sprocket Alignment—Sprockets must be aligned accu-rately. This can best be accomplished by checking with astraight edge along the finished sides of the sprockets asshown in the drawing.Chain Tension—Chains should be installed fairly tight withonly a small amount of slack. In the case of vertical drivesthe chain should be kept snug. New chains will loosen upslightly as the joints seat themselves, causing initial elonga-tion which is many times greater than the elongation duringthe balance of the chain life. After the first several weeks ofoperation it is advisable to adjust the centers, particularly onlong center drives. After this initial elongation, with propercare and lubrication, roller chains will give long service with-out undue elongation or wear.Center Distance—It is desirable to provide some meansof adjusting the center distance between sprockets.

This is particularly true with drives of long center distance.When the centers are fixed it is advisable to use an idlersprocket to provide the proper chain tension originally,and also to compensate for natural chain wear.Hardened Teeth—The advantages gained by hardening theteeth of the small sprocket easily offset the hardening cost.Longer life, increased strength, equalized wear betweensmall and large sprockets—all result in lower overall cost tothe chain drive user. Hardened steel sprockets are recom-mended for use under the following conditions: 1. Slowspeed, heavily loaded drives where chains and sprocketsare selected on the basis of chain tensile strengths; 2. Mod-erate speed drives where sprockets have 17 teeth or less;3. High speed drives where sprockets have 25 teeth or less;4. When speed ratios exceed 4 to 1; 5. When drives areoperating exposed to dirty or dusty surroundings.

Lubrication of Roller Chain DrivesLubrication of roller chains is essential for effectively mini-mizing metal-to-metal bearing contact of pin-bushingjoints of the chain. Oil should be applied to outside plateand inside plate edges, since access to pin-bushing areasis possible only through clearances between the outsideplates and the inside plates. Oil applied on the center lineof rollers cannot reach pin-bushing joints.Chain drives should be protected against dirt and mois-ture and the oil supply kept free of contamination. Periodicoil change is desirable. A good grade of non-detergentpetroleum base oil is recommended. Heavy oils andgreases are generally too stiff to enter and fill the chainjoints. The following table indicates the proper lubricantviscosity for various surrounding temperatures. For highertemperatures—consult factory.Table 41—Chain Lubrication Viscosity for Surround-ing Temperatures

The method of lubrication, which is governed by thespeed of the chain and the amount of power transmitted,is indicated in the HP Rating Tables. Note that these areminimum lubrication requirements and the use of a better

type (for example, Type 4 instead of Type 3) is acceptableand may be beneficial. The four basic types of lubricationindicated are described below.Type A—Manual Lubrication—Oil is applied periodicallywith a brush or spout can, preferably once every 8 hoursof operation. Volume and frequency should be sufficient toprevent discoloration of lubricant in the chain joints.Type A—Drip Lubrication—Oil drops are directed be-tween the link plate edges from a drip lubricator, Volumeand frequency should be sufficient to prevent discolorationof lubricant in the chain joints. Precaution must be takenagainst misdirection of the drops by windage,Type B—Bath or Disc Lubrication—With bath lubrica-tion the lower strand of chain runs through a sump of oil inthe drive housing. The oil level should reach the pitch lineof the chain at its lowest point while operating. With disclubrication, the chain operates above the oil level. Thedisc picks up oil from the sump and deposits it onto thechain, usually by means of a trough. The diameter of thedisc should be such as to produce rim speeds between600 fpm minimum and 8000 fpm maximum.Type C—Oil Stream Lubrication—The lubricant is usu-ally supplied by a circulating pump capable of supplyingeach chain drive with a continuous stream of oil. The oilshould be applied inside the chain loop evenly across thechain width, and directed at the lower strand.
