? Type of input electrical power (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of equipment for being driven.
? Amount of horsepower necessary to provide suffi cient energy on the driven shaft.
? Full load speed from the fastest running shaft (rpm).
? Desired pace with the slow working shaft ( or even the demanded pace ratio). NOTE: If speeds are variable identify the horsepower to become transmitted at each and every speed.
? Diameters from the drive and driven shafts . . . This value may possibly restrict the minimum amount of teeth to the sprockets.
? Center distance with the shafts.
? Note the place and any room limitations that may exist. Typically these limitations are within the greatest diameter of sprockets (this restricts using single strand chains) or the width in the chain (this restricts the use of multi-strand chains).
? Conditions with the drive together with a determination on the class of load (uniform, reasonable or heavy), serious operating temperatures or chemically aggressive environments must be mentioned.
