Definitions

  • the invention relates to a support disk bearing, in particular for the shaft of an open-end spinning rotor, the shaft being mounted in a wedge gap formed by the support disks and the support disks having a running surface made of an elastic covering, against which the shaft is pressed.
  • the object of the present invention is to improve a support disk bearing in such a way that the service life of the treads and thus of the entire rotor bearing is increased.
  • the tread has at least one interruption, which is formed by a recess which is bridged by the line of contact of the rotor shaft.
  • 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 during this storage, which leads to wear and to the 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 Form of such an endless groove '7 barge 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 cannot fall into the grooves, but bridges them.
  • the course of the grooves 71 as well as the groove 70 in the embodiment a in FIG. 3 to the edge of the running surface makes the spinning rotor run smoothly not affected, since the tread is large enough for the shaft in the area where the groove runs out at the edge. If necessary, however, the groove 71 or 70 can also end in front of the tread edge, should this prove to be necessary.
  • ribs 8 made of plastic at a distance from one another in the base body of the support disk, which likewise results in a running surface interrupted by cutouts.
  • the cutouts are formed by bores 9 which are arranged in a row one behind the other in the center of the tread.
  • 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.
  • 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.
