Abstract:
Gear unit comprising a hollow shaft (10) for gate drives, and a hollow shaped part (20) which is structured and arranged to be introduced into the hollow shaft (10),an outside (22) and inside (24) of the hollow shaped part (20) are structured and arranged such that both the connection with a shaft accommodated within the hollow shaped part (20) and the hollow shaft (10) accommodating the hollow shaped part (20) are form-locking in a rotation direction, a force-locking connection in an axial direction between the hollow shaped part (20) and outer hollow shaft (10) is unnecessary as there is no axial force and contact between the hollow-shaped (20) and outer hollow shaft (10) by said form-locking connection in the rotation direction prevents, to a large extent, shifting of the hollow-shaped part (20) with respect to the outer hollow shaft (10), and said form-locking connection in the rotation direction, between the outer hollow shaft (10) and hollow part (20) can be loosened by removing the hollow-shaped part (20) in the axial direction.
