? Type of input power (electric motor, internal combustion engine with mechanical or hydraulic drive).
? Type of tools to get driven.
? Amount of horsepower essential to supply suffi cient power towards the driven shaft.
? Full load speed on the quickest operating shaft (rpm).
? Desired pace on the slow operating shaft ( or the necessary velocity ratio). NOTE: If speeds are variable decide the horsepower to be transmitted at each and every pace.
? Diameters on the drive and driven shafts . . . This value may perhaps restrict the minimum number of teeth for that sprockets.
? Center distance with the shafts.
? Note the position and any room limitations that could exist. Normally these limitations are to the greatest diameter of sprockets (this restricts the usage of single strand chains) or even the width in the chain (this restricts the use of multi-strand chains).
? Conditions on the drive including a determination from the class of load (uniform, reasonable or heavy), extreme operating temperatures or chemically aggressive environments needs to be mentioned.
