selection guidelines Ž next generation drive lambda chain step 1 consider the following factors when selecting drive lambda a b c d e f source of power type of machine horsepower hp to be transmitted rpm of driving and driven shafts diameter of driving and driven shafts center distance between shafts step 2 determine the service factor use table i to obtain the appropriate service factor value selection guidelines drive lambdaŽ step 3 calculate the design hp rating multiply the hp value by the appropriate service factor value to obtain the design hp rating service factor because the drive capacity of the chain is subject to various application factors the following table has been designed to rectify power changes in relation to load fluctuation table i service factor type of impact machines electric motor or turbine source of power internal combustion engine with hydraulic drive without hydraulic drive smooth belt conveyors with small load fluctuations chain conveyors centrifugal blowers textile machines machines with small load fluctuations centrifugal compressors marine engine conveyors with some load fluctuation automatic furnaces dryers pulverizers general machine tools compressors general work machines general paper mills presses construction and mining machines vibration machines oil well rigs rubber mixers machines with reverse or impact loads 1.0 1.0 1.2 some impact 1.3 1.2 1.4 large impact 1.5 1.4 1.7 15
