? Type of input energy (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of tools to get driven.
? Amount of horsepower essential to provide suffi cient energy for the driven shaft.
? Full load pace from the fastest operating shaft (rpm).
? Desired pace of your slow operating shaft ( or even the demanded velocity ratio). NOTE: If speeds are variable determine the horsepower to become transmitted at each and every velocity.
? Diameters of your drive and driven shafts . . . This value could restrict the minimum variety of teeth for that sprockets.
? Center distance on the shafts.
? Note the place and any space limitations that may exist. Usually these limitations are to the highest diameter of sprockets (this restricts the usage of single strand chains) or even the width on the chain (this restricts the usage of multi-strand chains).
? Conditions from the drive which includes a determination of your class of load (uniform, moderate or heavy), extreme working temperatures or chemically aggressive environments must be noted.
