? Type of input power (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of products for being driven.
? Amount of horsepower necessary to supply suffi cient energy for the driven shaft.
? Full load pace from the fastest running shaft (rpm).
? Desired velocity of the slow running shaft ( or the essential pace ratio). NOTE: If speeds are variable decide the horsepower to get transmitted at each speed.
? Diameters with the drive and driven shafts . . . This value could restrict the minimal quantity of teeth for your sprockets.
? Center distance with the shafts.
? Note the place and any space limitations that could exist. Typically these limitations are on the highest diameter of sprockets (this restricts the use of single strand chains) or the width on the chain (this restricts the use of multi-strand chains).
? Conditions on the drive such as a determination from the class of load (uniform, reasonable or heavy), extreme operating temperatures or chemically aggressive environments really should be mentioned.
