? Type of input power (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear to be driven.
? Amount of horsepower necessary to supply suffi cient energy to your driven shaft.
? Full load speed of your fastest working shaft (rpm).
? Desired pace of the slow running shaft ( or the necessary pace ratio). NOTE: If speeds are variable identify the horsepower to be transmitted at every pace.
? Diameters on the drive and driven shafts . . . This worth may perhaps restrict the minimum quantity of teeth for the sprockets.
? Center distance from the shafts.
? Note the place and any room limitations that could exist. Generally these limitations are on the maximum diameter of sprockets (this restricts the use of single strand chains) or the width of your chain (this restricts using multi-strand chains).
? Conditions of the drive which includes a determination of your class of load (uniform, reasonable or heavy), severe operating temperatures or chemically aggressive environments need to be noted.
