? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of products to get driven.
? Amount of horsepower essential to provide suffi cient energy for the driven shaft.
? Full load pace in the fastest running shaft (rpm).
? Desired speed with the slow running shaft ( or the needed pace ratio). NOTE: If speeds are variable decide the horsepower to become transmitted at every single speed.
? Diameters of your drive and driven shafts . . . This worth might restrict the minimum variety of teeth for your sprockets.
? Center distance in the shafts.
? Note the place and any room limitations that may exist. Typically these limitations are around the greatest diameter of sprockets (this restricts the usage of single strand chains) or even the width of your chain (this restricts the usage of multi-strand chains).
? Conditions of the drive which includes a determination of the class of load (uniform, moderate or hefty), severe operating temperatures or chemically aggressive environments ought to be mentioned.
