? Type of input energy (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of tools for being driven.
? Amount of horsepower necessary to supply suffi cient electrical power for the driven shaft.
? Full load pace from the quickest operating shaft (rpm).
? Desired velocity from the slow operating shaft ( or the necessary speed ratio). NOTE: If speeds are variable figure out the horsepower for being transmitted at each and every pace.
? Diameters in the drive and driven shafts . . . This worth may possibly restrict the minimum quantity of teeth for that sprockets.
? Center distance of the shafts.
? Note the position and any space limitations that may exist. Normally these limitations are over the maximum diameter of sprockets (this restricts the use of single strand chains) or the width from the chain (this restricts using multi-strand chains).
? Conditions of the drive like a determination of your class of load (uniform, moderate or heavy), significant working temperatures or chemically aggressive environments really should be mentioned.
