? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of products for being driven.
? Amount of horsepower demanded to provide suffi cient energy on the driven shaft.
? Full load velocity of your fastest running shaft (rpm).
? Desired velocity of your slow operating shaft ( or even the required speed ratio). NOTE: If speeds are variable identify the horsepower for being transmitted at each and every pace.
? Diameters in the drive and driven shafts . . . This worth might restrict the minimum variety of teeth for that sprockets.
? Center distance in the shafts.
? Note the position and any area limitations that may exist. Normally these limitations are within the greatest diameter of sprockets (this restricts the usage of single strand chains) or even the width of your chain (this restricts the usage of multi-strand chains).
? Conditions in the drive which include a determination on the class of load (uniform, moderate or hefty), significant working temperatures or chemically aggressive environments must be noted.
