Abstract
Reaction torque of a planetary gear type torque multiplier assembly is measured in apparatus which includes multiple stage torque multiplying apparatus and a torque readout meter which is operated by the reaction torque sensed. A reaction coupling arrangement operatively associated with a planetary torque multiplier includes a ring gear around which the planetary gears traverse. The ring gear is attached to a pivotable reaction torque cup. The reaction torque cup is biased by a pair of parallel extending deflection beams. As torque is applied, the ring gear deflects in accordance with reaction torque, and the amount of deflection 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 torque indications after the applied torque is terminated.
