Decouplable belt pulley mechanism for circulating part of generator, has inner ring including bearing surface for roller body in outer surface, and rolling unit arranged between free-wheel mechanism and roller bodies

摘要

The mechanism has an inner ring (4) made in a single-piece, to form a shaft for transmitting a torque. The inner ring has a bearing surface (16) for a roller body (22) i.e. ball, in an outer surface (4b) that lies against a tubularly arranged outer ring (3) and a rotational symmetrical cylindrical rig hub (18) for a clamping body (28) of a free-wheel mechanism (6). A rolling unit (5) has a set of roller bodies (22, 23) arranged between the free-wheel mechanism and another set of roller bodies.
