Definitions

  • the invention relates to a support disc bearing for Open-end spinning rotor according to the preamble of claim 1.
  • support disks are state of the art in which the hub body both one or more grooves and / or one or have several radially projecting ribs.
  • the race this support disc usually has a cooling groove (DE 37 19 445 A1).
  • DE 195 49 466 A1 describes, for example, a support disk with a hub body, which has a bell-shaped profile on its outer circumference and a closed annular groove in the area of the hub body side surfaces.
  • the race which consists of a polymeric material, is cast into these structures, so that the race is almost positively fixed on the hub body.
  • the The invention is therefore based on the object, the known Support washers continue to improve.
  • the design of the support plate according to the invention has on the one hand the advantage that almost the same in all areas Lining thickness of the race is a good, that is, even Derivation of the rotation of the rotor shaft on the Tread of the support disc resulting from flexing work, inevitable heat in the metallic hub body is guaranteed so that heat accumulation areas in Race material that causes the material to age prematurely, can be avoided.
  • the form-fitting clasping of the free flanks of the M-shaped race secure prevents these flanks from moving away from the hub body over time to solve.
  • the race also has, as in claim 2 set out in the middle of the tread a V-shaped Cooling groove.
  • a cooling groove leads to an enlargement the convection surface, which is also positive for the Heat dissipation of the race affects.
  • the V-shaped cooling groove is as stated in claim 3, concave in the groove base.
  • the configuration according to FIG. 4 leads to an advantageous one Embodiment of the race, on the one hand sufficient heat dissipation is guaranteed and on the other hand remains ensured that the over the rotor shaft on the Running surface loading, which is jointly responsible for the generation of frictional heat is not too great.
  • the free flanks of the M-shaped raceway converge (claim 5).
  • the free flanks are clamped between the V-shaped middle region and the laterally arranged ribs of the radial profile of the hub body.
  • a circumferential undercut in the area of the base of the ribs reliably prevents the free flanks from being released from their gripping, for example under the influence of the centrifugal forces that occur. This means that the race is securely attached to the hub body.
  • Support disks are characterized by a during operation low air resistance, which is the case with open-end spinning machines, which a variety of such according to the invention Have support disks, positive for the total energy consumption the machine. Due to the convex side surfaces is also the total radiation area of the hub body enlarged and thus further the heat emission to the environment improved.
  • FIG. 1 shows a support disk bearing arrangement 1 as it is is used in open-end rotor spinning devices.
  • Such support disc bearing arrangements 1 usually have two pairs of support disks arranged on a bearing block 2, which form a gusset between them.
  • the axes the pairs of support disks can either be set be arranged or run parallel.
  • pairs of support disks acts during operation an axial thrust component on the rotor shaft and holds it in contact with a rotor shaft end arranged mechanical axial bearings.
  • FIG 1 only the front of the two pairs of support disks is shown horizontal support disc pair 3 with support discs 4 and 5 shown.
  • the support disks 4, 5 are non-rotatable an axis 6, which is mounted in a bearing housing 7 is.
  • the bearing housing 7 is in turn on the bearing block 2 established.
  • the support plate 4 or 5 which in Figure 2 in an enlarged Scale is shown, has a metallic Hub body 14 and a molded onto the hub body 14, preferably made of a polymeric material, for example Polyurethane, existing race 15.
  • the hub body 14, the For example, is made of aluminum, has convex shapes Side surfaces 16, 17.
  • the hub body 14 also has a central through hole 18 through which the Support washers 4 and 5 by means of a press fit on axis 6 are fixable.
  • a receptacle 19 arranged in the one (not shown), preferably also convex Sealing plug can be fixed.
  • the hub body 14 On its outer circumference, the hub body 14 has a radial protruding profile 20 on.
  • This profiling 20 consists as can also be seen from FIG. 3, from a V-shaped trained middle structure 21 and two laterally next to the Center structure 21 arranged, circumferential ribs 22, 23rd
  • a race 15 is cast around this profiling 20, which, as already indicated above, from a polymer Material is made, and which has an approximately M-shaped shape.
  • the race 15 has on its entire Cross-sectional area an approximately the same covering thickness D.
  • Die Free edges 24, 25 of the race 15 are between the V-shaped center structure 21 and the side arranged ribs 22, 23, each in the region of their base have an undercut 29, securely fixed.
  • the race 15 also a V-shaped cooling groove 27, the width B corresponds at least to the depth T.
  • the groove bottom is 28 the cooling groove 27 has a concave curvature.
