? Type of input power (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of products for being driven.
? Amount of horsepower needed to provide suffi cient energy to the driven shaft.
? Full load speed on the quickest running shaft (rpm).
? Desired pace of the slow working shaft ( or the demanded velocity ratio). NOTE: If speeds are variable decide the horsepower to be transmitted at every speed.
? Diameters of the drive and driven shafts . . . This worth may restrict the minimum quantity of teeth to the sprockets.
? Center distance on the shafts.
? Note the place and any area limitations that could exist. Commonly these limitations are about the greatest diameter of sprockets (this restricts the use of single strand chains) or the width of your chain (this restricts the usage of multi-strand chains).
? Conditions of your drive such as a determination from the class of load (uniform, reasonable or hefty), serious working temperatures or chemically aggressive environments need to be noted.
