? Type of input electrical power (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of equipment for being driven.
? Amount of horsepower demanded to supply suffi cient power to the driven shaft.
? Full load pace of your fastest running shaft (rpm).
? Desired speed in the slow working shaft ( or the necessary speed ratio). NOTE: If speeds are variable decide the horsepower to get transmitted at every single speed.
? Diameters from the drive and driven shafts . . . This worth could restrict the minimum variety of teeth for your sprockets.
? Center distance of the shafts.
? Note the position and any space limitations that may exist. Generally these limitations are to the greatest diameter of sprockets (this restricts using single strand chains) or even the width with the chain (this restricts using multi-strand chains).
? Conditions of the drive including a determination from the class of load (uniform, moderate or hefty), significant working temperatures or chemically aggressive environments needs to be noted.
