Bearing free-wheel unit, has free-wheel unit arranged between roller bearing rows to release rotation of inner ring relative to outer ring in rotating direction and to block rotation of inner ring in another rotating direction

摘要

The unit (1) has an inner ring (2), and an outer ring (4) that is arranged concentric to the inner ring. A roller bearing unit (3) is arranged between the inner ring and the outer ring, where the roller bearing unit is formed as a double-row angular roller bearing. An axial free-wheel unit (7) e.g. clamp body free-wheel clutch, is arranged between two roller bearing rows (5, 6). The free-wheel unit releases the rotation of the inner ring relative to the outer ring in a rotating direction, and blocks the rotation of the inner ring relative to the outer ring in another rotating direction.
