? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to get driven.
? Amount of horsepower expected to provide suffi cient energy to the driven shaft.
? Full load velocity with the fastest operating shaft (rpm).
? Desired pace of the slow working shaft ( or the necessary pace ratio). NOTE: If speeds are variable identify the horsepower to get transmitted at every single velocity.
? Diameters of the drive and driven shafts . . . This value may restrict the minimal amount of teeth for that sprockets.
? Center distance with the shafts.
? Note the place and any area limitations that may exist. Normally these limitations are around the optimum diameter of sprockets (this restricts the usage of single strand chains) or even the width with the chain (this restricts using multi-strand chains).
? Conditions with the drive such as a determination in the class of load (uniform, moderate or heavy), extreme working temperatures or chemically aggressive environments should be mentioned.
