? Type of input electrical power (electric motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear for being driven.
? Amount of horsepower expected to supply suffi cient energy for the driven shaft.
? Full load pace with the quickest running shaft (rpm).
? Desired pace of your slow running shaft ( or even the essential pace ratio). NOTE: If speeds are variable identify the horsepower to be transmitted at each speed.
? Diameters from the drive and driven shafts . . . This worth may well restrict the minimal variety of teeth for that sprockets.
? Center distance with the shafts.
? Note the position and any space limitations that may exist. Usually these limitations are about the greatest diameter of sprockets (this restricts using single strand chains) or the width of the chain (this restricts the use of multi-strand chains).
? Conditions in the drive including a determination of the class of load (uniform, moderate or hefty), significant operating temperatures or chemically aggressive environments need to be mentioned.
