? Type of input electrical power (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear to get driven.
? Amount of horsepower demanded to supply suffi cient electrical power to the driven shaft.
? Full load speed of the quickest operating shaft (rpm).
? Desired pace on the slow operating shaft ( or the necessary pace ratio). NOTE: If speeds are variable identify the horsepower to become transmitted at each and every velocity.
? Diameters on the drive and driven shafts . . . This worth could restrict the minimal quantity of teeth for the sprockets.
? Center distance of the shafts.
? Note the place and any area limitations that could exist. Normally these limitations are within the highest diameter of sprockets (this restricts using single strand chains) or even the width on the chain (this restricts the usage of multi-strand chains).
? Conditions in the drive together with a determination of the class of load (uniform, moderate or hefty), severe working temperatures or chemically aggressive environments ought to be mentioned.
