? Type of input power (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of products to be driven.
? Amount of horsepower demanded to provide suffi cient electrical power to the driven shaft.
? Full load speed from the fastest working shaft (rpm).
? Desired speed from the slow running shaft ( or the demanded velocity ratio). NOTE: If speeds are variable decide the horsepower to become transmitted at each speed.
? Diameters on the drive and driven shafts . . . This worth could restrict the minimum amount of teeth for that sprockets.
? Center distance of your shafts.
? Note the position and any room limitations that could exist. Usually these limitations are within the greatest diameter of sprockets (this restricts using single strand chains) or the width of your chain (this restricts the use of multi-strand chains).
? Conditions of your drive which includes a determination of your class of load (uniform, moderate or heavy), severe working temperatures or chemically aggressive environments ought to be noted.
