Hub City PowerTorque Shaft Mount Reducers Selection Procedure Hub City PowerTorque Reducers are selected on the put speeds to 200 RPM and ratings up to 200 HP.

5 The basis of input horsepower and output speed. There selection tables have been established so that once are ten double reduction PowerTorque Models avail- the horsepower and driven speed are known the appro- able in nominal ratios of 9:1, 15:1, and 25:1 with out- priate model can be readily selected. AGMA Load Classification Numbers Determine the AGMA Load Classification Number the reducer ratings for the stresses created by different for your application from the AGMA tables in the types of loads. The AGMA Load Classes provide for a Engineering Manual. In mechanical drives the presence momentary or starting load of times for Class I, of shock loads will usually reduce the life of the Reducers . for Class II, and for Class III. Refer to the AGMA. In order to provide optimum service in heavily loaded tables in the Engineering Manual for further information applications, it is necessary to use load classes to adjust and cautions on the selection of proper service factors.
