? Type of input electrical power (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of tools for being driven.
? Amount of horsepower demanded to provide suffi cient electrical power on the driven shaft.
? Full load velocity with the quickest operating shaft (rpm).
? Desired speed with the slow running shaft ( or the demanded velocity ratio). NOTE: If speeds are variable determine the horsepower to get transmitted at every single velocity.
? Diameters from the drive and driven shafts . . . This worth may perhaps restrict the minimal variety of teeth for the sprockets.
? Center distance from the shafts.
? Note the place and any space limitations that may exist. Usually these limitations are about the greatest diameter of sprockets (this restricts the use of single strand chains) or even the width with the chain (this restricts using multi-strand chains).
? Conditions of the drive together with a determination in the class of load (uniform, moderate or heavy), serious operating temperatures or chemically aggressive environments must be mentioned.
