? Type of input electrical power (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of products to get driven.
? Amount of horsepower essential to supply suffi cient power on the driven shaft.
? Full load velocity in the fastest working shaft (rpm).
? Desired speed in the slow working shaft ( or the essential 
pace ratio). NOTE: If speeds are variable decide the horsepower to get transmitted at every single velocity.
? Diameters on the drive and driven shafts . . . This worth may perhaps restrict the minimum variety of teeth for the sprockets.
? Center distance from the shafts.
? Note the position and any area limitations that could exist. Commonly these limitations are around the maximum diameter of sprockets (this restricts the usage of single strand chains) or even the width on the chain (this restricts the use of multi-strand chains).
? Conditions in the drive which include a determination of the class of load (uniform, moderate or heavy), severe working temperatures or chemically aggressive environments need to be mentioned.
