Definitions

  • the invention relates to a running disk for a spinning machine, comprising a hub ring, which consists of a first and second carrier and is connected radially on the outside with a support ring made of polymeric material, the hub ring and the support ring being detachably attached to one another in a non-destructive manner.
  • Such a disc is known from DE 42 29 154 A1.
  • the running disk is designed as a supporting disk for a supporting disk bearing of a spinning rotor and has an exchangeable supporting ring.
  • the support ring is fixed between two fixing rings which extend in the radial direction, each of the fixing rings having claws in the region of its radially outer boundary which extend in the axial direction to one another.
  • the support ring is arranged with only a small axial pressure between the two carriers in order to avoid deformation of the support ring in the radial direction and the unsatisfactory concentricity properties resulting therefrom. It should be noted, however, that the two carriers have a different shape and are screwed together. With regard to the inexpensive manufacturability of the hub ring, such an embodiment is unsatisfactory.
  • the invention has for its object to develop a disc of the type mentioned in such a way that the hub ring is easier and cheaper to manufacture economically.
  • the first and the second carrier are designed to match and are arranged in mirror image to one another.
  • the advantage here is that only one tool is required to produce the two carriers.
  • the two carriers, which are designed to match, are assembled with the support ring being interposed to form the hub ring. Possible errors in the assembly of the hub ring are reduced to a minimum by the configuration according to the invention.
  • the two carriers preferably consist of a polymeric material with a modulus of elasticity of 17 to 20 GPa, an elongation at break of 1.8 to 2.4% and a heat resistance of 150 ° to 250 ° C.
  • the carrier in the assembled state in the area of its outer circumference for receiving the support ring together define a groove-shaped and undercut recess and that the support ring with at least one radially inward-pointing, hammer-head-shaped projection in a form-fitting manner and under elastic prestress in the Recess is arranged.
  • the recess is preferably circumferentially formed and receives the correspondingly designed projection in a form-fitting manner with pretension.
  • the support ring is preferably made of polyurethane, which has a high abrasion resistance and therefore requires good usage properties of the entire running disk during a long period of use.
  • the two carriers of identical design have an essentially C-shaped cross section and touch one another in the region of their radial projections.
  • the hub ring consisting only of the two carriers is essentially double T-shaped.
  • the advantage here is that the hub ring has a very high rigidity in the radial direction, since the support each other in contact with each other. Even at comparatively high loads on the running disk in the radial direction, the rigid design of the hub ring ensures a very good concentricity of the disk.
  • the two carriers can consist, for example, of a polymeric material.
  • the advantage here is that the hub ring has a very high dimensional stability and only a low mass inertia element due to the mutual support of the carriers to one another with only very low weight. With regard to the rapid and precise speed change of the running disk, this is a noteworthy advantage.
  • the first and the second carrier can be held together by a fastening device.
  • the fastening device can be formed, for example, only by the support ring itself or by a clip connection formed in one piece with the carriers. If, for example, several running disks braced against one another in the axial direction are used, the use of secondary fastening aids is unnecessary.
  • the two beams are held by the bracing and the support rings themselves. If, on the other hand, the carriers are pressed onto a shaft, it is necessary that the carriers are connected to one another by a fastening device in order to avoid axial relative displacements.
  • a clip connection is preferably used.
  • the surfaces of the supports delimiting the recess are each at least partially provided with a knob-shaped surface profile and that the surface profile is designed to prevent rotation.
  • a relative rotation of the hub ring relative to the support ring in the circumferential direction is prevented in such an embodiment even if comparatively high torques with little tensioning of the projection in the recess should be transferred.
  • the support disk and the carrier are positively connected to one another in the region of their recess.
  • the running disk is preferably used as a texturing disk.
  • texturing extruded threads run over the support ring and are roughened and / or stretched, for example.
  • a hub ring which consists of two carriers, which are connected by a clip connection and fixed by a press fit on a shaft.
  • 2 shows the bracing of three running disks according to the invention, which are arranged with a sliding seat on a common shaft.
  • 3 and 4 each show a section of one of the carriers according to FIGS. 1 or 2 in the region of the recess.
  • the hub ring 1 of the running disk consists in each case only of a first and second carrier 2, 3, which are designed to match and are arranged in mirror image to one another.
  • the two supports 2, 3 have an essentially C-shaped cross section and are supported on one another by their radial projections 9. In the assembled state, the two supports 2, 3 delimit in the region of their outer circumference a groove-shaped and undercut recess 5 that is open in the radial direction to accommodate a circumferential, circumferential, hammer-head-shaped projection 6 of the support ring 4.
  • the projection 6 is form-fitting under elastic prestress held within the recess 5.
  • the support ring 4 consists of polyurethane.
  • the two carriers 2, 3 consist of a polymeric material.
  • Fig. 1 the disc is held by a press fit on a shaft.
  • the two supports 2, 3 are clamped together in the axial direction by a clip connection 7. Evasive movements due to radial loads on the support ring 4 are thereby excluded.
  • the carriers 2, 3 are held together in such a way that they can be detached from one another without damage if the support ring 4 is worn out.
  • the clip connection 7 ensures that the support ring 4 is held on the carrier 2, 3 only with a permissible tension.
  • the roundness and the concentricity of the outer diameter of the support ring 4 is not adversely affected thereby.
  • the carriers 2, 3 of the running disk can be provided with a reflector, for example, in the region of their end faces facing away from one another.
  • FIG. 2 shows an arrangement of running disks that differs from FIG. 1.
  • Three of the running disks according to the invention are fastened on a shaft by means of a sliding seat and are associated with one another in each case by spacers 11 with an axial distance.
  • the running disks designed as texturing disks are braced against one another in the axial direction by the tensioning screw 12.
  • the bracing and the groove-shaped and undercut recess 5 prevent lifting of the support rings 4 from the V-shaped contact surfaces 10 of the carriers 2, 3.
  • FIG. 3 shows a detail from the area of the recess 5 of the two supports 2, 3 and the projection 6 of the support ring 4 in an enlarged view. It can be seen that the two supports 2, 3, viewed in cross section, have radially outside V-shaped bearing surfaces 10 together. It is advantageous here that a radial preload is introduced into the support ring 4 in the axial direction by the bracing of the first and second carriers 2, 3.
  • the V-shaped bearing surfaces 10 of the first and second Carrier 2, 3 form an angle of preferably 15 ° with the axis of rotation 13.
  • the support ring 4 shows a detail from the second carrier 3, which is provided in the region of the recess 5 with a surface profile 8 which increases the contact area.
  • the surface profile 8 is designed to prevent rotation in order to hold the projection 6 of the support ring 4 in a form-fitting manner within the recess 5.
  • the support ring 4 is elastically deformed in the area of the knob-shaped surface profile 8.
