? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of tools to get driven.
? Amount of horsepower expected to supply suffi cient energy to the driven shaft.
? Full load pace from the fastest working shaft (rpm).
? Desired pace of your slow working shaft ( or even the demanded speed ratio). NOTE: If speeds are variable ascertain the horsepower to get transmitted at each and every pace.
? Diameters of the drive and driven shafts . . . This value could restrict the minimal quantity of teeth for that sprockets.
? Center distance in the shafts.
? Note the place and any space limitations that could exist. Commonly these limitations are about the greatest diameter of sprockets (this restricts using single strand chains) or the width of the chain (this restricts the use of multi-strand chains).
? Conditions in the drive such as a determination in the class of load (uniform, reasonable or hefty), serious operating temperatures or chemically aggressive environments needs to be mentioned.
