2 CHAIN SPROCKET DRIVE The Transmission of mechanical power without slippage and with a high degree of maintained efficiency is a basic function of the Roller Chain Drive. SELECTION OF ROLLER CHAIN DRIVES 1. Determine the R.P.M. and diameter of the high speed shaft. 2. Determine the total H.P. to be transmitted. 3. Select the chain pitch and number of teeth in the small sprocket, a) Be sure the small sprocket will accomodate the high speed shaft diameter. b) If the high speed shaft diameter exceeds the maximum bore in the selected small srpcket it will be necessary either to increase the number of teeth in the sprocket or select the next large pitch chain. 4. Determine the required ratio: RPM high speed shaft RPM slow speed shaft = Ratio 5. Multiply the number of teeth in the small sprocket by the ratio to obtain the number of teeth in the large sprocket. 6. The actual horsepower P is multiplied by the correcting factor K1, K2 according to table.
