? Type of input electrical power (electric motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear to be driven.
? Amount of horsepower expected to supply suffi cient electrical power for the driven shaft.
? Full load speed from the quickest running shaft (rpm).
? Desired speed on the slow operating shaft ( or the necessary velocity ratio). NOTE: If speeds are variable identify the horsepower to become transmitted at each and every velocity.
? Diameters in the drive and driven shafts . . . This worth could restrict the minimal number of teeth to the sprockets.
? Center distance of the shafts.
? Note the position and any space limitations that could exist. Generally these limitations are to the optimum diameter of sprockets (this restricts the usage of single strand chains) or even the width on the chain (this restricts using multi-strand chains).
? Conditions from the drive which includes a determination on the class of load (uniform, reasonable or hefty), serious operating temperatures or chemically aggressive environments really should be mentioned.
