摘要： In rotor spinning devices whose rotors are mounted in a support-disk bearing and in which a support disk (1) has openings (5, 9) serving for the contactless measurement of speed for an optical control of a spinning-start carriage, deposits of dirt, especially fine dust, can build up in said openings (5, 9). This impairs the detection of signals. The portion of the inner surface (19) of the openings (6, 9) of a support disk (1) which is located in the direction of the outer edge of the support disk (1) forms such an angle (&agr;) with a line parallel to the axis of rotation (27) that the buildup of deposits of dirt is prevented.

摘要： An open-end spinning apparatus has a spin rotor (1) which, by means of its shaft (11) is supported by support plates (4), wherein as an abutment for the axially directed force on the spin rotor (1), an aerostatic axial bearing (6) is provided. The bearing surface (115) of the spin rotor (1) operates together with a bearing plate (63) of the axial bearing (6). The bearing surface (115) or the bearing plate (63) are comprised of a construction material of polyimide. Advantageously, the polyimide is combined with an additive, namely graphite, for instance.

摘要： A method of operating an open-end spinning device (1) whose spinning rotor (3) is supported with its rotor shaft (4) radially and axially positioned via a magnetic bearing arrangement (5) which comprises two magnetic bearings with spaced permanent magnet pairs (33, 34 and 43, 44), a central position control device (50) with actor coils (32, 42), and a rotor position sensor (51). An output signal (ASLS) of the position sensor (51) is processed in the central position control device (50) such that a coil current (i) initiated by a controller (53) is initially regulated toward zero by negative feedback of an integrator (55). A positive feedback of the coil current (i) subsequently takes place by negation of the input signal (ESI) of the integrator to at least intermittently increase the coil current (i) in the actor coils (32, 42) and thereby lift and transfer the spinning rotor (3) from its axial catch bearing (45) into its operating position wherein the coil current (i) is regulated back toward zero in the actor coils (32,42).

摘要： A rotor shaft of an open-end spinning rotor is provided with a peg-like shaft end having a reduced diameter. The shaft end has a front-end supporting surface which can be arranged to a step bearing, said supporting surface being provided with a wear-resistant insert. The reduced diameter of the peg-like shaft end is at least 0.68 times the diameter of the rotor shaft. In addition, the reduced diameter of the shaft end measures at least 0.82 times the length of the peg-like shaft end.

摘要： The present invention concerns a procedure for the reworking of a open-end spinning apparatus for a spin rotor, which is carried in the V-notch between support disks and is supported by a ball axial thrust bearing. Where the reworking is concerned, the bearing block of the open-end spinning apparatus is dismounted, the ball axial thrust bearing is removed from the bearing block and in accord with the invention, is replaced by an aerostatic bearing in the bearing block.
