? Type of input energy (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of equipment to be driven.
? Amount of horsepower expected to supply suffi cient electrical power on the driven shaft.
? Full load pace of your fastest working shaft (rpm).
? Desired velocity in the slow operating shaft ( or even the required pace ratio). NOTE: If speeds are variable identify the horsepower to become transmitted at just about every pace.
? Diameters with the drive and driven shafts . . . This worth may well restrict the minimal variety of teeth for that sprockets.
? Center distance of your shafts.
? Note the position and any room limitations that may exist. Generally these limitations are around the optimum diameter of sprockets (this restricts using single strand chains) or even the width from the chain (this restricts the use of multi-strand chains).
? Conditions in the drive together with a determination on the class of load (uniform, moderate or heavy), severe operating temperatures or chemically aggressive environments must be mentioned.
