Apparatus and method for measuring the torque transmitted across coupled rotating shafts using load cells located between power imparting surfaces and power receiving surfaces of shafts rotating jointly about a common axis of rotation for directly determining the tangential driving force and, hence, the torque therebetween. In one form, radially inwardly facing teeth supported by one shaft drivingly couple with radially outwardly facing teeth supported by the other shaft. Load cells at the interface between the teeth of the two shafts provide signals representative of the torque, or torque variations.

Apparatus for measuring the torque transmitted across coupled rotating shafts using load cells located between power imparting surfaces and power receiving surfaces of shafts rotating jointly about a common axis of rotation for directly determining the tangential driving force and, hence, the torque therebetween. The apparatus includes tubular spacers journaled together and supporting the shafts, load cells and power surfaces. In one form concentric overlapping spacers are provided with one spacer having a plurality of radially extending fingers projecting into corresponding slots in the other spacer. Load cells at the interface between the fingers and sides of the slots provide signals representative of torque.
