? Type of input energy (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear to be driven.
? Amount of horsepower essential to supply suffi cient electrical power to your driven shaft.
? Full load velocity on the fastest operating shaft (rpm).
? Desired speed in the slow operating shaft ( or even the expected velocity ratio). NOTE: If speeds are variable ascertain the horsepower to be transmitted at each and every pace.
? Diameters of the drive and driven shafts . . . This worth may well restrict the minimum variety of teeth for that sprockets.
? Center distance of the shafts.
? Note the position and any area limitations that could exist. Normally these limitations are within the greatest diameter of sprockets (this restricts the usage of single strand chains) or the width of your chain (this restricts the usage of multi-strand chains).
? Conditions of your drive like a determination on the class of load (uniform, moderate or hefty), significant working temperatures or chemically aggressive environments should be noted.
