Abstract
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.
