? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to become driven.
? Amount of horsepower demanded to supply suffi cient power to your driven shaft.
? Full load velocity of the fastest working shaft (rpm).
? Desired velocity on the slow operating shaft ( or the necessary pace ratio). NOTE: If speeds are variable determine the horsepower to become transmitted at each pace.
? Diameters of your drive and driven shafts . . . This value may perhaps restrict the minimal variety of teeth for the sprockets.
? Center distance of the shafts.
? Note the position and any space limitations that may exist. Typically these limitations are within the highest diameter of sprockets (this restricts using single strand chains) or even the width in the chain (this restricts the usage of multi-strand chains).
? Conditions on the drive including a determination with the class of load (uniform, moderate or hefty), severe operating temperatures or chemically aggressive environments really should be mentioned.
