? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to become driven.
? Amount of horsepower demanded to supply suffi cient energy for the driven shaft.
? Full load speed in the quickest working shaft (rpm).
? Desired pace of the slow running shaft ( or the needed pace ratio). NOTE: If speeds are variable ascertain the horsepower to get transmitted at each pace.
? Diameters of your drive and driven shafts . . . This worth might restrict the minimum quantity of teeth for the sprockets.
? Center distance on the shafts.
? Note the place and any room limitations that may exist. Usually these limitations are around the highest diameter of sprockets (this restricts the use of single strand chains) or the width in the chain (this restricts the usage of multi-strand chains).
? Conditions of the drive which includes a determination with the class of load (uniform, reasonable or heavy), extreme working temperatures or chemically aggressive environments ought to be mentioned.
