? Type of input energy (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to get driven.
? Amount of horsepower necessary to supply suffi cient power for the driven shaft.
? Full load speed from the fastest operating shaft (rpm).
? Desired pace with the slow operating shaft ( or even the demanded velocity ratio). NOTE: If speeds are variable identify the horsepower to become transmitted at every velocity.
? Diameters with the drive and driven shafts . . . This worth could restrict the minimum variety of teeth for that sprockets.
? Center distance on the shafts.
? Note the place and any space limitations that may exist. Ordinarily these limitations are about the highest diameter of sprockets (this restricts the usage of single strand chains) or the width on the chain (this restricts the use of multi-strand chains).
? Conditions of the drive such as a determination of your class of load (uniform, moderate or heavy), serious operating temperatures or chemically aggressive environments must be noted.
