? Type of input power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear for being driven.
? Amount of horsepower necessary to supply suffi cient electrical power to the driven shaft.
? Full load pace of the quickest working shaft (rpm).
? Desired speed in the slow working shaft ( or the demanded speed ratio). NOTE: If speeds are variable decide the horsepower to become transmitted at just about every velocity.
? Diameters on the drive and driven shafts . . . This worth may restrict the minimum number of teeth to the sprockets.
? Center distance of your shafts.
? Note the place and any room limitations that could exist. Typically these limitations are within the highest diameter of sprockets (this restricts the use of single strand chains) or the width in the chain (this restricts using multi-strand chains).
? Conditions with the drive together with a determination with the class of load (uniform, moderate or heavy), serious operating temperatures or chemically aggressive environments really should be mentioned.
