? Type of input electrical power (electrical motor, internal combustion engine with mechanical or hydraulic drive).
? Type of gear to become driven.
? Amount of horsepower necessary to supply suffi cient power to the driven shaft.
? Full load speed with the fastest running shaft (rpm).
? Desired pace in the slow operating shaft ( or the expected speed ratio). NOTE: If speeds are variable identify the horsepower for being transmitted at every pace.
? Diameters with the drive and driven shafts . . . This value could restrict the minimal amount of teeth for the sprockets.
? Center distance in the shafts.
? Note the position and any room limitations that could exist. Ordinarily these limitations are over the optimum diameter of sprockets (this restricts the use of single strand chains) or the width of the chain (this restricts the use of multi-strand chains).
? Conditions with the drive such as a determination in the class of load (uniform, moderate or hefty), extreme operating temperatures or chemically aggressive environments needs to be mentioned.
