| 摘要 |
The invention relates to a gear unit in which a cable, band or similar (2) 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 (2) is fastened at both ends (21, 22) to an oscillating intermediary single-piece (3) divided into two segments (31, 32). The cable rests against the outer walls of the intermediary (2) and is wound around the shaft (41) of the drive (4) so as to transfer a driving torque. A position sensor is assigned to the inner segment (31) of the intermediary piece (3), and a torque sensor (6) is mounted between both segments (31, 21) of the intermediary piece (3). In the inventive gear unit, a fast rotational movement of the drive is transformed into a slow rotational movement. This takes place without play and provides a good synchronization characteristic.
