? Type of input power (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to get driven.
? Amount of horsepower required to provide suffi cient energy towards the driven shaft.
? Full load velocity from the quickest operating shaft (rpm).
? Desired pace on the slow working shaft ( or the expected pace ratio). NOTE: If speeds are variable establish the horsepower to be transmitted at just about every pace.
? Diameters on the drive and driven shafts . . . This value may possibly restrict the minimal amount of teeth to the sprockets.
? Center distance from the shafts.
? Note the position and any area limitations that may exist. Normally these limitations are over the maximum diameter of sprockets (this restricts the use of single strand chains) or even the width of the chain (this restricts the use of multi-strand chains).
? Conditions in the drive which includes a determination in the class of load (uniform, moderate or hefty), severe working temperatures or chemically aggressive environments must be noted.
