Eccentric gear for use as control gear in e.g. industrial robot, has planetary axle arranged in planetary carrier, and drive part including eccentric sleeve with eccentric part, where eccentric sleeve is rotatably mounted in carrier

摘要

The gear has a drive part for driving central wheels (3, 14), which roll at a ring gear with an internal toothing and perform rotation. An output part is driven by the central wheels. A planetary axle (18) is arranged in a planetary carrier, and coupled with the central wheels. The drive part includes an eccentric sleeve (6) with an eccentric part, where the eccentric sleeve is rotatably mounted in the planetary carrier. The eccentric sleeve encloses an eccentric axle (17). The central wheel is arranged between planetary carrier disks (16).
