Page 2 1 - KUTF Motor Overhung Load (Not Required for Example) If the output shaft of gear drive 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 = 2 TK OHL = Overhung Load (LB.) = Shaft Torque (LB.-INS.)
