ervice factor that satisfies your requirements, 7 Series basic reducer number will be indicated . For complete catalog part number, descriptions and options, refer to Page 7 .Overhung Load If the output shaft of speed reducer is connected to the driven machine by other than flexible coupling, an overhung load is imposed on the shaft . This load may be calculated as follows: OHL = 2TK OHL = Overhung Load (LB .) = Shaft Torque (LB .IN .) = PD of Sprocket, Pinion or Pulley (IN .) = Load Connection Factor Load Connection Factor Sprocket or Timing Belt . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 .0 Pinion and Gear Drive . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 .2 Pulley and -Belt Drive . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 .5 Pulley and Flat Belt Drive . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 .5 An overhung load greater than permissible load value may be reduced to an acceptable value by the use of sprocket, pinion or pulley or larger PD . Relocation of the load closer to the center of reducer will also increase OHL capacity . Permissible overhung loads and output shaft thrust loads are listed for each reducer in the tables on Pages 3-3 .
