Essential Facts For Drive Chain Selection

? Type of input energy (electrical motor, inner combustion engine with mechanical or hydraulic drive).
? Type of gear to be driven.
? Amount of horsepower needed to provide suffi cient power towards the driven shaft.
? Full load speed of your fastest operating shaft (rpm).
? Desired velocity of your slow running shaft ( or the needed speed ratio). NOTE: If speeds are variable establish the horsepower to get transmitted at every single pace.
? Diameters of the drive and driven shafts . . . This value may possibly restrict the minimum number of teeth for your sprockets.
? Center distance on the shafts.
? Note the position and any space limitations that may exist. Commonly these limitations are within the greatest diameter of sprockets (this restricts using single strand chains) or the width of your chain (this restricts the use of multi-strand chains).
? Conditions of your drive including a determination on the class of load (uniform, moderate or heavy), severe working temperatures or chemically aggressive environments needs to be mentioned.
