A gear unit in which a cable, band or similar device is fitted between the drive and the output in order to transform a fast rotational movement at the drive end, which is limited in both directions, into a slow rotational movement at the output end. The cable is fastened at both ends to an oscillating intermediary single-piece divided into two segments, and rests against the outer walls of the intermediary piece and is wound around the shaft of the drive so as to transfer a driving torque. A position sensor is assigned to the inner segment of the intermediary piece, and/or a torque sensor is mounted between both segments of the intermediary piece. A fast rotational movement of the drive is transformed into a slow rotational movement without play, and provides a good synchronization characteristic.
A gear unit for converting a fast, drive-side rotational movement that is limited in both directions into a slow output movement by means of a force-transmitting element, which is provided between the drive and the output, characterized in that the force-transmitting element (2;
The gear unit according to one of the foregoing claims, characterized in that an opto-electronic, position-sensitive detector (61) serving as a torque sensor (6) is mounted in the center of the center part (32, 323′, 323″) of the outside segment (32, 32′, 32″), and, on the other side of the slot (34) embodied between the inside and outside segments, a slotted screen (62) is mounted to the inside segment (31) directly opposite the detector, with a light source (63) being disposed behind this screen.
