? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of products to become driven.
? Amount of horsepower needed to supply suffi cient energy towards the driven shaft.
? Full load pace with the fastest operating shaft (rpm).
? Desired speed from the slow working shaft ( or even the required pace ratio). NOTE: If speeds are variable determine the horsepower for being transmitted at each pace.
? Diameters with the drive and driven shafts . . . This value could restrict the minimum variety of teeth to the sprockets.
? Center distance of the shafts.
? Note the place and any room limitations that may exist. Ordinarily these limitations are around the optimum diameter of sprockets (this restricts the usage of single strand chains) or even the width of your chain (this restricts the use of multi-strand chains).
? Conditions on the drive such as a determination with the class of load (uniform, moderate or hefty), significant operating temperatures or chemically aggressive environments needs to be noted.
