Abstract
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).
Claims7
A thrust bearing for an open-end spinning rotor assembly having a rotor shaft supported in a bearing slot defined by at least one pair of adjacent support disks, the thrust bearing comprising a bearing housing stationarily supporting at least one first magnetic element and a magnetic bearing device supporting at least one second magnetic element, the magnetic bearing device being disposed within the bearing housing with the polarity of the respective magnetic elements arranged to dispose the magnetic bearing device for rotation relative to the bearing housing, a receiving groove formed in one of the magnetic bearing device and a bearing portion of the rotor shaft, and annular resilient O-ring means positioned in the groove for establishing an elastic connection between the magnetic bearing device and the bearing portion of the rotor shaft for releasable attachment of the rotor shaft to the magnetic bearing device for integral rotation thereof.
