? 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 on the driven shaft.
? Full load velocity with the fastest operating shaft (rpm).
? Desired pace with the slow working shaft ( or the necessary pace ratio). NOTE: If speeds are variable identify the horsepower to get 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 may 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 in the class of load (uniform, moderate or heavy), extreme operating temperatures or chemically aggressive environments need to be mentioned.
