摘要

Between a first flange (2), which is seated on a rotor shaft (1) designed as a hollow shaft, and a second flange (4), which is arranged with the ability for axial displacement on a drive shaft (3), there is a clutch lining (5). The two flanges (2, 4) and the clutch lining (5) form a slipping clutch, the clutch torque of which can be adjusted by means of a compression spring (19). The second flange (4) which is axially displaceable on the drive shaft (3), is coupled rotationally, via cylindrical rollers (7), to a braking ring (6) which can be braked by brake linings (8, 9) which engage on it from the sides. A thrust washer (14), which is guided in axially movable fashion on the housing (15) and between which and the housing (15) the braking ring (6) and the two brake linings (8, 9) are situated, is displaced axially via a pressure lever (13) which is actuated by a brake-air device (11) and a compression spring (10) in order to brake the drive shaft (3) to a halt. The clutch is particularly suitable for small electric hoists. IMAGE
