An open-end spinning device (1) with a spinning rotor (3) whose rotor cup rotates at a high speed in a vacuum-loaded rotor housing (2) closable by a conduit plate (27). The spinning rotor (3) is supported with its rotor shaft (4) in the bearing nip of a support-disk bearing (5) free of axial thrust and positioned in axial direction by a magnet bearing (18). The direction of rotation (S, Z) of the spinning rotor (3) can be selectively set via the direction of the rotor drive (V or R). The conduit plate (27) comprises a receptacle (34) in which exchangeable conduit-plate adapters (12.sub.S or 12.sub.Z) can be fixed in coordination with the particular direction of rotation (S or Z) of the spinning rotor (3).

Open-end spinning device for production Z- or S-twisted yarns

A thrust bearing for an open-end spinning rotor (1) supported by its rotor shaft (2) in the bearing slot of a support-disk bearing arrangement (4). The thrust bearing has a magnetic bearing system (10) or (25) comprising magnetic support elements (12), (13) stationarily arranged on a thrust bearing housing (11) and a rotating magnetic bearing device (14) fastened to rotor shaft (2). Bearing element (15) of magnetic bearing device (14) is releasably connected to rotor shaft (2) via an elastic connection (20), (21) positively supported in corresponding receiving grooves (22), (23) of either the rotor shaft or the magnetic bearing device (14).

Thrust bearing for an open-end spinning rotor

An open-end spinning device with a forwardly open suctioned rotor housing, a high speed spinning rotor rotatably disposed in the rotor housing, and a fiber conduit plate for closing the forward opening in the rotor housing. The fiber conduit plate has an interchangeably disposed conduit plate adapter defining an opening from a fiber guide conduit into the rotor and a yarn take-off nozzle. The conduit plate adapter can be releasably fixed securely in place in a receptacle area of the fiber conduit plate by means of a central fastening arrangement comprising a threaded connection and a magnetic coupling between the fiber conduit plate and the conduit plate adapter.
