Definitions

  • the invention relates to a support disk of a support ring and a mounted on the outer circumference of the support ring support ring made of an elastic polymeric material for the storage of a rotor on an open-end spinning machine.
  • Support discs for the storage of rotors on open-end spinning machines are subject to high demands, as they are dynamically loaded high and should also have a high temperature resistance. Of importance is also more and more energy needs of the spinning machine, which has a significant impact on the operating costs of the spinning machine. It is therefore desirable, despite increased rotor speeds to keep the wear of the support disks as low as possible, which equally affects the energy requirements.
  • the drive of a rotor of an open-end spinning machine is shown via a support disk pair and the basic design of a support disk.
  • the support discs have support rings on which are mounted on the outer circumference supporting rings made of polymeric material. For improved heat dissipation of the support ring is provided in its central region with a cooling groove.
  • the support disk is formed from at least two axially contacting part discs, which limit cavities by partial axial distance by means of webs, which extend to the outer periphery of the support disk. At least one of these dividing discs has axial computations through which air is sucked into the cavities during rotation of the support disk, which air is blown out radially after passing through the cavities.
  • the thermal load of the support disk and the rotor is reduced.
  • such a support disk has relatively high production costs and there is a risk that accumulate in the cavities dirt and lint, which lead to a troubled run of the support disk and may cause damage to the product or the spinning machine result.
  • the invention has for its object to avoid the disadvantages of the previously known support discs and to provide an improved support plate, which is inexpensive to produce and allows much higher speeds than previously possible.
  • the new support disk is characterized in that the support ring is provided on at least one of the sides of its outer edge with a side ring which is arranged at a distance from the outer edge, connected via carriers to the support ring and which also has a support ring on its outer circumference.
  • a support disc which effectively has a unilaterally hollowed support ring, which is firmly connected via the carrier to the support ring, but in the areas between the individual carriers has slots through which during the rotation of the support disk cooling air is promoted.
  • the carriers can be designed accordingly.
  • the outer edge of the support ring is formed in a ring shape and arranged on this outer edge of the side ring.
  • the side ring with the support ring and the carriers forms a uniform, made of the same material part. This part can be produced for example by die casting, injection molding or extrusion.
  • the carriers themselves are arranged at equal angular intervals. At least three carriers are used. In the simplest form, the carriers consist of the outer edge of the support ring with the side ring connecting webs. It is also possible to form the carrier in the form of stub posts that emanate from the support ring itself or from the bottom of the outer edge of the support ring. However, the preferred embodiment provides that the carriers have the shape of paddles which extend to the hub of the support ring. Regardless of whether the carriers are designed as webs, stub posts or paddles is their Surface designed and provided with bends that air is conveyed in the desired direction through the slots.
  • the support disk itself is cooled from the inside, but also components that are in the area, such as rotor, bearings, brake shoes and the like.
  • the flow effects lead to lower temperatures in the entire aggregate, thus preventing overheating and thus prolonging the runtime of the machine components.
  • the air flow from the space below the side ring of the disc can be directed radially outward or vice versa.
  • corotating or opposing air flows can be generated.
  • Both the support ring and the side ring are provided with support rings, which can be connected in a conventional manner with the support ring or side ring.
  • the composite can be non-positive or positive.
  • the support rings can be formed on their radial treads with profilings, e.g. Grooves, to be equipped.
  • the support ring is made of a plastic and a hub made of metal is inserted into its hub. This results in an improved fit on the journal. Generally, however, it should be noted that the support ring incl. Side ring is also made entirely of plastic or metal.
  • the advantages of the new support disk consist in the good heat dissipation and also a particularly good cleaning ability, since all cavities are easily accessible from the outside and visible.
  • the preparation of the support disk can be done so that a support ring on at least one side of its outer edge with an axial protruding rim is produced, which is connected via support to the support ring, wherein the support ring and the rim is provided on its outer peripheries with a support ring. Subsequently, the ring is separated from the support ring by the transition region between the support ring and the ring is cut so that an open between the carriers to the space below the ring annular groove is made. The wreath then forms the side ring.
  • a corresponding groove is attached on both sides of the support ring. The groove shape is retained in the support sections.
  • the support disks 1 are each shown in section and in the perspective view. They consist of the support ring 2 with the support ring 3 made of a polymeric material and the side ring 7, which also has a support ring 10.
  • Support ring 2 and side ring 7 are a unitary component, which is produced by injection molding. They are connected to each other via the webs 4 designed as carrier 9.
  • polyurethane is selected with a hardness greater than 90 ° Shore A.
  • the two support rings 3 and 10 are spaced apart by the annular groove 20.
  • the annular groove 20 may extend to the webs 4 or even into it.
  • the support disk 1 consists of the support ring 2, which is provided on its outer circumference with the support ring 3 made of an elastic, polymeric material.
  • the support ring 3 is chemically bonded to the support ring 2 and anchored in a head-shaped annular groove 14.
  • On its on the representation of the figure shown right side of the outer edge 6 of the support ring 2 has the side ring 7.
  • This side ring 7 is arranged with the distance 8 to the outer edge 6 of the support ring 2.
  • carrier 9 of the side ring 7 is held on the support ring 2.
  • the support ring 2, side ring 7 and the carrier 9 are made uniformly from the same material.
  • the side ring 7 is also provided on its outer circumference with a support ring 10 which has the same shape as the support ring 3 of the support ring 2.
  • the Carrier 9 are arranged at equal angular intervals 11.
  • the openings 21 are made by attaching the annular groove 20.
  • FIG. 3 an embodiment of the support disk 1 is shown, in which the carrier 9 have the shape of paddles 16.
  • the carrier 9 connect directly to the hub 13 of the support ring 2.
  • the hub 13 is axially elongated.
  • the support rings 3 and 10 are also positively connected to the support ring 2 here.
  • the support ring 2 is made of a plastic and has in its hub 13, the existing metal bushing 17th
  • the most favorable method of manufacturing the support disk is achieved in that the support ring 2 is provided on at least one of its sides with an axially projecting rim, which is connected via the carrier 9 with the support ring 2.
  • Support ring 2 and wreath are provided on its outer circumference with a support ring.
  • an annular groove 20 is mounted between the rim and the support ring 2 from the outside, which separates the ring from the support ring 2 in the lying between the carriers 9 sections.
  • the groove 20 is continued until the free space 22 below the side ring 7, in spoke-like carriers 9, the free spaces 23 between the spokes or vanes 16 is reached. In this way, the slot-like openings 21 are made between the carriers 9, through which the air, depending on the shape of the carrier 9, from the inside out or vice versa, is passed.
