Abstract
A torque transmitter comprising two members 1, 2 rotatable relative to each other and serving to transmit a torque, and which has the ability to continuously measure the transmitted torque. The transmitter includes a transducer ring 3, and a displacement measuring device 6 having at least two noncontacting sensors 4, 5 for detecting the axial position of the transducer ring 3 relative to a reference member 7. The members 1, 2 are inter-connected via transverse beams and connected with the transducer ring 3 via fork-like members, so that upon a torque being transmitted between the members 1, 2, the latter are rotated relative to one another proportionally to the torque, and the transducer ring 3 is axially displaced. To achieve an error-free and reproducible determination of the torque, the transducer ring 3 and the reference member 7 are provided with surfaces 8, 9 which are substantially parallel to each other and axially aligned with each other, and the sensors 4, 5 occupy a fixed position and are arranged such that they measure against the surfaces 8, 9 either in a direction opposite to each other or toward each other.
