Abstract
A high sensitivity torque transducer capable of installation between the motor and the output reduction gear train in the housing of a rotating machine, which has a limited axial space therefor, has a disk shaped first member fixed to a fixed portion of the housing. A disk shaped second member has splined coupling with the first member and the second member to provide sliding coupling with a floating portion of an output drive train. This coupling transfers reaction torque back from the output shaft, through the drive train, and into the second member. Shear webs are formed between the inner and outer diameters of the second member by removing some material to form torsion concentrator voids. Strain gages mounted on the shear webs and bridged with appropriate resistors provide an output signal in response to torsional strains imposed on the second disk shaped member. The output signal is routed to a calibrated signal processor and relay control unit.
