? Type of input power (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of tools for being driven.
? Amount of horsepower necessary to provide suffi cient energy towards the driven shaft.
? Full load speed in the quickest running shaft (rpm).
? Desired speed of the slow running shaft ( or even the expected velocity ratio). NOTE: If speeds are variable establish the horsepower to get transmitted at each and every velocity.
? Diameters from the drive and driven shafts . . . This worth might restrict the minimum number of teeth to the sprockets.
? Center distance in the shafts.
? Note the place and any area limitations that could exist. Ordinarily these limitations are to the maximum diameter of sprockets (this restricts the usage of single strand chains) or the width with the chain (this restricts using multi-strand chains).
? Conditions of the drive which includes a determination of the class of load (uniform, reasonable or hefty), extreme working temperatures or chemically aggressive environments should be noted.
