? Type of input electrical power (electric motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to become driven.
? Amount of horsepower demanded to supply suffi cient power to your driven shaft.
? Full load velocity of the fastest working shaft (rpm).
? Desired velocity with the slow working shaft ( or the necessary pace ratio). NOTE: If speeds are variable determine the horsepower for being transmitted at each pace.
? Diameters of your drive and driven shafts . . . This value may perhaps restrict the minimal amount of teeth for the sprockets.
? Center distance of the shafts.
? Note the place and any space limitations that may exist. Normally these limitations are within the highest diameter of sprockets (this restricts using single strand chains) or the width in the chain (this restricts the usage of multi-strand chains).
? Conditions on the drive including a determination with the class of load (uniform, moderate or hefty), severe operating temperatures or chemically aggressive environments really should be mentioned.
