? Type of input electrical power (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear to get driven.
? Amount of horsepower required to provide suffi cient electrical power towards the driven shaft.
? Full load velocity in the quickest running shaft (rpm).
? Desired velocity of your slow working shaft ( or the demanded speed ratio). NOTE: If speeds are variable identify the horsepower to be transmitted at every speed.
? Diameters in the drive and driven shafts . . . This worth may restrict the minimum number of teeth for your sprockets.
? Center distance of your shafts.
? Note the place and any space limitations that may exist. Ordinarily these limitations are on the optimum diameter of sprockets (this restricts the usage of single strand chains) or the width of the chain (this restricts using multi-strand chains).
? Conditions of your drive together with a determination of the class of load (uniform, reasonable or hefty), significant operating temperatures or chemically aggressive environments really should be mentioned.
