? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to get driven.
? Amount of horsepower necessary to supply suffi cient energy to your driven shaft.
? Full load velocity of your fastest operating shaft (rpm).
? Desired velocity of your slow working shaft ( or the essential pace ratio). NOTE: If speeds are variable identify the horsepower to be transmitted at every single velocity.
? Diameters of the drive and driven shafts . . . This value may restrict the minimal variety of teeth to the sprockets.
? Center distance on the shafts.
? Note the place and any area limitations that could exist. Normally these limitations are over the optimum diameter of sprockets (this restricts the usage of single strand chains) or even the width on the chain (this restricts the usage of multi-strand chains).
? Conditions in the drive together with a determination on the class of load (uniform, moderate or heavy), extreme operating temperatures or chemically aggressive environments need to be mentioned.
