? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of equipment to get driven.
? Amount of horsepower demanded to provide suffi cient energy towards the driven shaft.
? Full load velocity with the quickest working shaft (rpm).
? Desired velocity on the slow operating shaft ( or even the required pace ratio). NOTE: If speeds are variable decide the horsepower for being transmitted at every single velocity.
? Diameters on the drive and driven shafts . . . This value may well restrict the minimum amount of teeth for that sprockets.
? Center distance with the shafts.
? Note the position and any room limitations that could exist. Ordinarily these limitations are on the greatest diameter of sprockets (this restricts using single strand chains) or even the width from the chain (this restricts using multi-strand chains).
? Conditions from the drive like a determination with the class of load (uniform, moderate or hefty), serious working temperatures or chemically aggressive environments should be mentioned.
