Drive Chain Selection5. General SelectionDrive ChainProcedure 1Procedure 2Procedure 3Procedure 4-5ProcedureData required for selectionService factor K sObtain thedesign kW or HPTentatively select the chainsize and number of teeth N’ forthe small sprocket from theprovisional selection tableDetermine the number ofteeth N for the large sprocketfrom the speed ratio iMake N’ >=15 for smallsprockets andN design kW or HPYFits in the distancebetween shaftsYFitting on the max.shaft diameterYChain and sprocketdeterminedIf the number of teeth for the small sprocket hasbeen determined, then multiply this value by thespeed ratio and determine the number of teeth forthe large sprocket.It is appropriate to have more than 15 teeth forthe small sprocket. However, if the number ofteeth for the large sprocket exceeds 120 as aresult, then this is not favorable. When thishappens, reduce the number of teeth for the smallsprocket; although, it is recommended to usemore than 13 teeth.Procedure 7If possible, try to avoid using an offset link whenusing an odd number of links. Instead, try adjustingthe distance between the shafts until an even numberof links is attained.Procedure 7Calculate the chain length L(number of links)Procedure 8Determine the method oflubrication from number ofrevolutions of the smallsprocketEndA-96
