Non-slip, electromagnetically operated circuit coupling with overload function

摘要

1. Slip ring-less, electromagnetic switching clutch with overload function, having - a hub (1) driven by a shaft, - a coil carrier mounted thereon, with an electromagnet which is fixed in the circumferential direction, - a pressure flange (2) provided as a driven element, which is also mounted rotatably on said shaft and fixed in the axial direction relative thereto, and which is rigidly connected to the armature disc (3) of the electromagnet in the circumferential direction, - and a switching part (31) mounted in the torque flux between the hub (1) and the pressure flange (2), and engageable by the magnetic force of the electromagnet which is adjustable via the voltage, by which switching part the pressure flange (2) can be coupled with the hub (1), characterised in that the coil carrier consisting of a magnet part (4), a bushing (5) and a flange ring (6) is mounted axially immovably relative to the hub (1) and the axial position of the magnet part (4) is adjustable on the bushing (5) via a thread (20), in that the armature disc (3) is connected axially displaceably relative to the pressure flange (2) and rigidly to the switching part (31), and in that the switching part (31) is engageable in recesses in the hub (1) in order to transmit torque.
