Definitions

  • the invention relates to a support disk bearing for the shaft of an open-end spinning rotor which is mounted in a wedge gap formed by support disks and is driven directly by a tangential belt, an axial thrust being exerted on the shaft via the support disks in order to press it against an axial bearing, and the support disks Have a tread made of an elastic covering against which the shaft is pressed.
  • the tread In operation, the tread is exposed to considerable stress due to the rapidly rotating shaft pressed against the tread with the pressure required for the drive, which is exacerbated by an existing imbalance and in particular also by the axial thrust on the shaft generated by the support disks. This stress leads to a relatively rapid wear and destruction of the tread and thus the rotor bearing. It is necessary to replace the support disks, which, due to the large number of spinning positions, incurs considerable costs for material, assembly and the loss of machine production time.
  • An open-end spinning device with a support roller bearing is also known, in which the rotor shaft is guided between liners provided with support rings and is driven indirectly via one of these liners. The axial position of the rotor shaft is secured by the force of a permanent magnet (DE-A-2.206.264).
  • a permanent magnet DE-A-2.206.264
  • the object of the present invention is to improve a support disk bearing according to the preamble of claim 1 in such a way that the service life of the treads and thus the entire rotor bearing is increased.
  • a shaft 1 of an open-end spinning rotor for which the support disk bearing is intended in particular, is mounted in the wedge gap of freely rotatable support disks 4 and 5 arranged in pairs on axes 2 and 3.
  • the support disks 4 and 5 are provided on their circumference with an elastic covering, which consists of plastic, for example polyurethane, or also of another suitable material and forms a running surface 40, 50 for the shaft 1.
  • a tangential belt 6 presses the shaft 1 with a predetermined pressure against the tread 40 and 50 and drives it.
  • Such a bearing is generally known and therefore does not require any further explanation, in particular also not with regard to the axial thrust exerted on the shaft 1 via the support disks during operation, in order to press it against an axial bearing.
  • the plastic covering is subjected to a high stress starting from the shaft 1 in this mounting, which leads to wear and destruction of the tread 40 and 50.
  • the tread is interrupted by cutouts. These recesses can be designed and arranged in various ways.
  • a groove-shaped recess is preferred, which runs in the direction of rotation of the support disks 4 and 5 and is arranged in the middle of the running surface 40 and 50 (FIG. 2).
  • the shape of such an endless groove 7 can be different.
  • the groove 7 can have, for example, a wedge-shaped, a rectangular, a semicircular or a trapezoidal shape.
  • two further grooves 7 ′ running parallel to the central groove are provided in addition to the centrally arranged groove 7, so that the running surface 40 or 50 is interrupted on its circumference by a total of three recesses.
  • the shaft 1 rests on the running surfaces 40 and 50 on both sides of the groove 7 and 7 ', whereby its line of contact, which can also become the contact surface when the shaft 1 is pressed against the elastic covering, bridges the groove freely.
  • the support of the shaft 1 on both sides of the recess ensures that the shaft 1 rolls off smoothly.
  • a groove 70 runs spirally over the circumference of the tread.
  • the embodiment b shows a running surface which is interrupted by a plurality of grooves 71 arranged at an angle to the direction of rotation of the support disk and at a distance from one another. The angle and the width of the grooves 71 are chosen so that the shaft 1 is not selected in the grooves 71 so that the shaft 1 cannot fall into the grooves, but bridges them.
  • the base body of the support disk is provided with a web 41 which extends into the vicinity of the running surface and forms a recess together with the elastic covering.
  • the effect of the invention seems to be based on the fact that, as a result of the rotation of the support disks, an air flow is generated in the cutouts, which cools the elastic covering and thereby reduces wear caused by excessive heating, for better heat dissipation and thus for preventing Destruction of the covering leading to heat build-up, the recess must have an appropriate dimension.
  • Experiments with a covering of 6 mm thickness have shown, for example, that a recess with a depth of approximately up to a third of the covering thickness is particularly effective. With the width of the recess, it should also be noted that effective ventilation and thus heat dissipation is guaranteed.
