Shaft unit for power transmission device, has sealing device arranged in groove for sealing chambers, channels arranged coaxial to each other, and hollow unit pressed with end area from other hollow unit, where former unit has projection

摘要

The unit (2) has a hollow-cylindrical unit (23) connecting another hollow-cylindrical unit (22) in a circumferential direction. The latter unit is pressed with an axial end area from the former unit, where the latter unit has a projection aligned in a radial direction. The projection is arranged in an axial direction and forms a groove with the former unit. A sealing device (18) is arranged in the groove for sealing coaxial pressure chambers (14, 15) in the axial direction next to each other, and two pressure medium guiding channels are arranged coaxial to each other. An independent claim is also included for a power transmission device comprising an outlet implemented as a shaft unit.
