ABSTRACT:
Reaction torque between a drive shaft of a drive motor and the stationary housing of the drive motor is measured by apparatus which includes a torque readout meter and a torque multiplying arrangement. The apparatus includes a pivot sleeve member which is operatively connected to and pivots with the drive motor housing. A single deflection beam extends from the sleeve to the housing of the apparatus. The beam deflects when the sleeve pivots under the application of torque from the drive motor. The amount of deflection of the beam is operatively coupled to the torque readout meter where an indication of torque is registered. The torque readout meter includes a stay set feature to maintain the maximum readings after the applied torque is terminated. Two output shafts supply output torque. One output shaft applies multiplied torque and reduced rotational speed as compared to the other shaft which is directly connected to the drive motor.
