? Type of input energy (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of tools to become driven.
? Amount of horsepower required to supply suffi cient power to the driven shaft.
? Full load pace on the fastest running shaft (rpm).
? Desired speed of the slow operating shaft ( or even the demanded pace ratio). NOTE: If speeds are variable identify the horsepower to become transmitted at just about every speed.
? Diameters on the drive and driven shafts . . . This value might restrict the minimum quantity of teeth for your sprockets.
? Center distance of your shafts.
? Note the place and any room limitations that could exist. Commonly these limitations are on the optimum diameter of sprockets (this restricts the usage of single strand chains) or even the width with the chain (this restricts using multi-strand chains).
? Conditions in the drive including a determination on the class of load (uniform, reasonable or hefty), extreme operating temperatures or chemically aggressive environments ought to be noted.
