? Type of input electrical power (electric motor, internal combustion engine with mechanical or hydraulic drive).
? Type of equipment to become driven.
? Amount of horsepower required to provide suffi cient electrical power for the driven shaft.
? Full load pace in the quickest operating shaft (rpm).
? Desired speed in the slow working shaft ( or the required speed ratio). NOTE: If speeds are variable figure out the horsepower for being transmitted at just about every speed.
? Diameters from the drive and driven shafts . . . This value might restrict the minimal number of teeth to the sprockets.
? Center distance of your shafts.
? Note the position and any space limitations that could exist. Normally these limitations are to the greatest diameter of sprockets (this restricts using single strand chains) or even the width on the chain (this restricts the usage of multi-strand chains).
? Conditions on the drive including a determination in the class of load (uniform, moderate or hefty), extreme working temperatures or chemically aggressive environments must be noted.
