  • Patent number: 5911674
    Abstract: In the case of a spindle for spinning or twisting machines, two housings, separated by an annular gap, are provided, namely an outer housing, secured to a spindle rail, and an inner housing which takes up the neck bearing and the step bearing for the shaft by means of supporting parts. The inner housing is connected to a supporting portion by a flexible joining piece, which supporting portion is adjustable and clampable onto the bottom surface of the outer housing. The bottom surface takes at least approximately the shape of a ball cup, whose center point is at most 30 mm away from the upper edge of the outer housing in vertical direction.

  • Patent number: 5802827
    Abstract: A spindle for a spinning or twisting machine comprises a guiding tube, which supports a neck bearing and a step bearing for a rotatably supported shaft. In proximity to the neck bearing, the guiding tube is supported by means of a metal membrane in a bearing housing, which is connectable to a spindle rail. The membrane is relatively rigid in radial direction; however, with respect to tilting motions of the guiding tube, it is very flexible. In the area of the step bearing, the guiding tube is supported against the bearing housing by means of a radial spring.

  • Patent number: 5775083
    Abstract: A spindle for spinning or twisting machines comprises a rigid inner sleeve which contains a neck bearing and a step bearing for a rotatably supported shaft and which inner sleeve is accommodated in a bearing housing, the bearing housing being fixed to a spindle rail. The inner sleeve is supported against the bearing housing by two radially symmetrical acting metal springs. The spring rate of the metal spring which faces the neck bearing amounts to at least five times and at most twenty times the spring rate of the metal spring facing the step bearing. The ring space between the inner sleeve and the bearing housing is filled with a highly viscous fluid. The inner sleeve is closed off against the ring space with an oilproof seal.

  • Patent number: 5528892
    Abstract: A spindle shaft is flexurally elastic at its shank part mounted in a bearing sleeve. The spindle shaft carries a belt-engaging wharve which is arranged underneath the neck bearing and to which a drive belt engages to rotate the spindle shaft. The bearing sleeve is arranged to have radial play within a spindle housing 10. The bearing sleeve is fastened at its lower end via a flexurally elastic tilting joint 40 to the spindle housing 10 connected rigidly to the spindle rail. The pulling force of the drive belt engaged to the wharve during operation deflects the bearing sleeve radially by tilting it about the tilting joint. Such deflection brings about, on the other hand, a pivoting of the bobbin-carrying upper part of the spindle shaft about the neck bearing in the opposite direction as a result of the bending moment occurring on the shank part, an inclination of the spindle shaft with its upper part is thus avoided.

  • Patent number: 4731985
    Abstract: A device for supporting the spindles of textile machines, in which a spindle support cartridge is radially held by means of a double system of elastically-yielding thrust members, disposed inside an outer casing for the cartridge, and radially acting on the cartridge itself.

  • Patent number: 4702625
    Abstract: In order to limit the horizontal displacement of the rotating assembly of the decanter at transitory speeds consecutive for example to an earthquake or other outside disturbance, a second series of shock absorbers is provided, disposed about the conventional shock absorbers and interposed, like the latter, between the bearing and the fixed frame, the operational characteristics of the shock absorbers of the two series being, of course, different so that those of the second series do not disturb the normal role of those of the first series.

  • Patent number: 4674272
    Abstract: A resilient element connects the housing of the spindle collar bearing with the spindle rail and contains a circumferential arrangement of resiliently flexible rods surrounding with play the housing of the spindle collar bearing in a substantially parallel relationship thereto. The resiliently flexible rods which are arranged at substantially uniform circumferential spacing from one another extend at both of their ends from an associated common retaining sleeve for the related rod ends. One such retaining sleeve is anchored at the spindle rail. The other retaining sleeve is fixedly anchored at the housing of the spindle collar bearing in a region or at a location spaced from a housing side at which the spindle exits from such housing. The resilient element forms a spatial parallelogram permitting only radial movement of the housing against the spring action of the resiliently flexible rods without inclined positioning of the housing.

  • Patent number: 4543780
    Abstract: In order to be able to achieve, in yarn manufacture, the very high speeds required by the textile industry in open-end spinning devices, for the purpose of increasing production, and in order to achieve high operating reliability and a long life of the spinning devices, the rotor which rotates at high speeds and is subject to a variable imbalance and which is guided in gas-dynamic radial plain bearings is guided in a bearing carrier which is elastically pivotable in relation to the rigid bearing journal. At the same time, the bearing journal is connected, but so as to be elastically pivotable, to the bearing carrier via a bearing-body joint. A first gas-dynamic radial plain bearing, which is located in the region in the center of gravity of the rotor, is arranged on the bearing carrier, and a second gas-dynamic radial bearing is arranged at the opposite end of the bearing carrier.

  • Patent number: 4519205
    Abstract: So as to be able to achieve, in yarn manufacture, the very high speed required by the textile industry in open-end spinning devices, for the purpose of increasing production, the rotors which are connected to the spinning container including a spinning groove, are designed as a hollow shaft, and this hollow shaft is guided radially on a bearing journal located in the interior of the hollow shaft by means of gas-dynamic radial plain bearings designed as inner bearings. Gas-dynamic axial plain bearings are provided for the axial guidance of the rotor rotating at very high speed. The rotor together with the spinning container can be pushed in and out in a simple way from the spinning side, and to position the rotor over the entire speed range, permanent magnets are located in the bearing journal opposite the rearside of the spinning container and in an annular widened portion of the bearing journal.
