? Type of input energy (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear to get driven.
? Amount of horsepower demanded to supply suffi cient energy towards the driven shaft.
? Full load speed from the fastest running shaft (rpm).
? Desired speed in the slow operating shaft ( or the required pace ratio). NOTE: If speeds are variable figure out the horsepower to become transmitted at each pace.
? Diameters from the drive and driven shafts . . . This worth may well restrict the minimum number of teeth to the sprockets.
? Center distance in the shafts.
? Note the position and any area limitations that could exist. Typically these limitations are within the maximum diameter of sprockets (this restricts the use of single strand chains) or even the width with the chain (this restricts the use of multi-strand chains).
? Conditions on the drive together with a determination on the class of load (uniform, moderate or heavy), extreme operating temperatures or chemically aggressive environments ought to be noted.
