? Type of input energy (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of products to become driven.
? Amount of horsepower required to provide suffi cient power towards the driven shaft.
? Full load pace in the quickest working shaft (rpm).
? Desired speed in the slow operating shaft ( or even the required velocity ratio). NOTE: If speeds are variable decide the horsepower for being transmitted at each speed.
? Diameters on the drive and driven shafts . . . This worth may possibly restrict the minimum number of teeth for the sprockets.
? Center distance of the shafts.
? Note the position and any room limitations that may exist. Generally these limitations are within the maximum diameter of sprockets (this restricts using single strand chains) or the width of the chain (this restricts the use of multi-strand chains).
? Conditions of your drive which includes a determination of the class of load (uniform, reasonable or hefty), severe operating temperatures or chemically aggressive environments needs to be noted.
