? Type of input power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of equipment to be driven.
? Amount of horsepower demanded to supply suffi cient electrical power on the driven shaft.
? Full load velocity with the fastest operating shaft (rpm).
? Desired pace of the slow running shaft ( or the essential velocity ratio). NOTE: If speeds are variable ascertain the horsepower for being transmitted at each pace.
? Diameters from the drive and driven shafts . . . This worth may possibly restrict the minimal amount of teeth to the sprockets.
? Center distance on the shafts.
? Note the place and any space limitations that may exist. Commonly these limitations are about the maximum diameter of sprockets (this restricts using single strand chains) or the width from the chain (this restricts using multi-strand chains).
? Conditions in the drive which include a determination in the class of load (uniform, reasonable or heavy), extreme working temperatures or chemically aggressive environments must be mentioned.
