? Type of input electrical power (electric motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear for being driven.
? Amount of horsepower necessary to supply suffi cient energy on the driven shaft.
? Full load velocity with the quickest running shaft (rpm).
? Desired pace with the slow working shaft ( or even the necessary speed ratio). NOTE: If speeds are variable identify the horsepower to get transmitted at each and every pace.
? Diameters of the drive and driven shafts . . . This value may perhaps restrict the minimal quantity of teeth for your sprockets.
? Center distance in the shafts.
? Note the place and any space 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 in the chain (this restricts the usage of multi-strand chains).
? Conditions in the drive together with a determination in the class of load (uniform, reasonable or hefty), extreme operating temperatures or chemically aggressive environments really should be mentioned.
