? Type of input power (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to be driven.
? Amount of horsepower required to supply suffi cient electrical power to your driven shaft.
? Full load velocity of your quickest operating shaft (rpm).
? Desired pace from the slow operating shaft ( or the expected velocity ratio). NOTE: If speeds are variable identify the horsepower for being transmitted at each pace.
? Diameters from the drive and driven shafts . . . This value may well restrict the minimal number of teeth to the sprockets.
? Center distance with the shafts.
? Note the position and any space limitations that could exist. Ordinarily these limitations are about the optimum diameter of sprockets (this restricts using single strand chains) or the width from the chain (this restricts using multi-strand chains).
? Conditions in the drive which include a determination on the class of load (uniform, reasonable or heavy), extreme working temperatures or chemically aggressive environments really should be noted.
