? Type of input electrical power (electric motor, internal combustion engine with mechanical or hydraulic drive).
? Type of products to get driven.
? Amount of horsepower expected to provide suffi cient power towards the driven shaft.
? Full load speed in the fastest working shaft (rpm).
? Desired speed with the slow running shaft ( or even the needed speed ratio). NOTE: If speeds are variable decide the horsepower to be transmitted at every single speed.
? Diameters with the drive and driven shafts . . . This worth could restrict the minimum variety of teeth for your sprockets.
? Center distance from the shafts.
? Note the position and any room limitations that may exist. Typically these limitations are on the greatest diameter of sprockets (this restricts the usage of single strand chains) or even the width of the chain (this restricts the use of multi-strand chains).
? Conditions of your drive such as a determination of the class of load (uniform, moderate or hefty), serious operating temperatures or chemically aggressive environments ought to be mentioned.
