Eccentric oscillating type reduction gear for use in hinge drive of industrial robot, has regulating parts for externally-toothed gear wheels for regulating and/or defining movement of externally-toothed gear wheels in axial direction

摘要

The gear has externally-toothed gear wheels (50A, 50B) engaged with an internally-toothed gear wheel from interior. Regulating elements (84, 85) include regulating parts (84A, 85A) for cylindrical outer pins (52C) of the internally-toothed gear wheel for regulating a movement of the pins in an axial direction. The elements are inwardly extended from the regulating parts in a radial direction. The elements include other regulating parts (84B, 85B) for the externally-toothed gear wheels for regulating and/or defining the movement of the externally-toothed gear wheels in the axial direction.
