? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to be driven.
? Amount of horsepower required to supply suffi cient electrical power towards the driven shaft.
? Full load pace of the quickest working shaft (rpm).
? Desired velocity on the slow working shaft ( or the essential velocity ratio). NOTE: If speeds are variable determine the horsepower for being transmitted at each and every velocity.
? Diameters on the drive and driven shafts . . . This worth may possibly restrict the minimum variety of teeth for the sprockets.
? Center distance of the shafts.
? Note the place and any area limitations that could exist. Commonly 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 the usage of multi-strand chains).
? Conditions in the drive including a determination from the class of load (uniform, moderate or hefty), serious working temperatures or chemically aggressive environments needs to be mentioned.
