Abstract
The electromagnetic clutch that serves for positive-locking assembly of concentric transmission shafts is inserted in a transmission housing (2) concentrically in relation to a shaft (1) and with a bushing (10) which externally encloses it, there resulting outside the bushing (10), in the area of the annular magnet (16), a free space that reduces the leakage, and the sliding sleeve (18) and the armature plate (19) together with the magnet (16) and eventual additionally provided bearings (25) can be preassembled, ready for operation and protected against damage. On the outer end of the bushing (10) can be provided at the same time a roller bearing (25) for the clutch part (24) that carries the counter gear (22) on the other shaft. Due to the design that reduces the leakage and the arrangement in the area of a seal gap also existing in the transmission housing (2), it is possible to work with clutches of small dimensions and a transmission housing (2) of equal size can be used optionally with and without inserted clutches.
