? Type of input power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of tools to become driven.
? Amount of horsepower required to provide suffi cient power towards the driven shaft.
? Full load pace of the quickest running shaft (rpm).
? Desired pace of your slow working shaft ( or the needed speed ratio). NOTE: If speeds are variable determine the horsepower for being transmitted at just about every velocity.
? Diameters in the drive and driven shafts . . . This value might restrict the minimal number of teeth for the sprockets.
? Center distance in the shafts.
? Note the place and any space limitations that may exist. Usually these limitations are over the optimum diameter of sprockets (this restricts using single strand chains) or even the width from the chain (this restricts using multi-strand chains).
? Conditions from the drive including a determination of the class of load (uniform, reasonable or heavy), serious operating temperatures or chemically aggressive environments must be noted.
