? Type of input electrical power (electric motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear to get driven.
? Amount of horsepower expected to provide suffi cient power to your driven shaft.
? Full load speed in the quickest operating shaft (rpm).
? Desired velocity of your slow working shaft ( or even the demanded velocity ratio). NOTE: If speeds are variable ascertain the horsepower to get transmitted at every velocity.
? Diameters with the drive and driven shafts . . . This value may perhaps restrict the minimal amount of teeth for your sprockets.
? Center distance with the shafts.
? Note the position and any area limitations that may exist. Commonly these limitations are around the maximum diameter of sprockets (this restricts using single strand chains) or the width from the chain (this restricts using multi-strand chains).
? Conditions of your drive which include a determination with the class of load (uniform, moderate or heavy), extreme operating temperatures or chemically aggressive environments must be noted.
