Abstract
A torque sensor includes a central hub, a fastening ring arranged radially outwardly from and coaxially circumferentially around the central hub, a continuous imperforate flange disc that extends radially between and interconnects the central hub and the fastening ring, and strain gages or other force transducers for measuring a torsional shear strain in the flange disc. The flange disc has blind pocket recesses that are recessed into the flange disc from one or both axial sides thereof. Each pocket recess is bounded at the bottom by a pocket recess floor. Strain transducers are mounted on the inner surfaces of the pocket recess floors in the pocket recesses and/or on the outer back surfaces of the pocket recess floors on the opposite side of the flange disc. The strain transducers measure torsional shear strain in the recess floors.
