Definitions

  • the present application relates to a sealing unit for the rotor housing an open-end rotor spinning device according to the preamble of the claim 1, in particular for the reprocessing of open-end rotor spinning devices with a seal for the rotor housing according to the prior art, for example as shown in DE 27 21 385 A.
  • the seal (15) shown in DE-OS 27 21 385 is formed like a membrane and over a short cylindrical bridge with a thickened edge bead 16 connected.
  • This seal is made of rubber or a rubber-like Material.
  • the seal has a pot-like shape, so that the disc 15 at an axial distance from the annular collar 19 of the spinning rotor 3 is held. This creates a chamber 18 between collar 19 and Seal intended to hinder the ingress of air.
  • the disadvantage of this Device is that the spinning rotor to achieve a sealing effect, a must have in the axial direction pronounced federal government.
  • the object of the present application is a sealing unit for an open-end rotor spinning device to suggest with their help spinning rotors with a smaller in the axial direction federal government also on rotor spinning machines of Prior art can be used, which is due to the lower Natural frequency of such spinning rotors the rotor speeds significantly can be increased.
  • a sealing unit is proposed which is easy to maintain and no special demands on the Mounting options on the machine provides.
  • the present object is achieved according to the invention with a sealing unit according to the features of claim 1 solved.
  • the sealing unit according to the invention when used in open-end rotor spinning machines, in particular during processing or modernization of already in operation Machines, these machines improved significantly. This allows the Speeds of the spinning rotor of the spinning machine can be substantially increased.
  • a more reliable sealing of the rotor housing reached. No work is required to seal Center, as this occurs automatically as a result of their floating storage.
  • the stop is arranged on the carrier plate particularly advantageous or alternatively the stop as a projection on the elastic element for mounting the sealing disc formed.
  • Figure 1 shows the sealing unit 1 according to the present invention, which a support plate 10 which carries a sealing disc 2, which by means of a elastic element 3 is held on the support plate 10.
  • the sealing washer 2 rests on the sealing edge 11 of the support plate 10.
  • the sealing washer 2 is on the support plate 10 by means of the elastic element 3rd held.
  • the elastic element 3 is by means of a fastener and held by means of a spacer bush 31 and in turn to the support plate 10 attached.
  • the plane in which the sealing disc 2 is located is vertical and aligned perpendicular to the (not shown) shaft of a spinning rotor.
  • the sealing washer 2 has the through hole 22, through which in the Operation, the shaft of the spinning rotor is guided.
  • the actual seal between the sealing washer 2 and the shaft of the spinning rotor is carried by the small gap extending between the rotor shaft and the limit of Through hole 22 results. Due to the floating mounting of the sealing disc, that is, that in their plane perpendicular to the rotor shaft can move freely on the sealing edge 11, it is achieved that the sealing disc 2 centered independently in relation to the rotor shaft. A setting when installing the sealing unit 1 by the maintenance personnel is not required. Together with the other features of the invention makes this the sealing unit 1 particularly suitable to retrofit rotor spinning machines and thus the requirements of a modern open-end rotor spinning machine adapt, because a fitting also on a machine which was originally not intended for it and therefore for the installation of the sealing unit 1 no mating surfaces or special mounting options having.
  • the support plate 10 has below the bore 4 an edge 5 on which the Sealing disc 2 can rest, so that they the support plate 10 without a lift of the elastic element 3 by a maintenance person not leave can.
  • the edge 5 advantageously comprises 90 ° to about 250 ° of the circumference the support plate 10. Due to the open to the edge of the sealing disc 2 Oval notch 23, the sealing disc 2 is particularly advantageous from the Sealing unit 1 removed without tools and inserted again become. For this purpose, only the elastic element must be raised.
  • the support plate 10 cooperates with a perforated counter-disc 6 and is bolted to this in the assembled state. Between the Counter-disc 6 and the support plate 10 is the wall of the not shown Housing clamped for the spinning rotor, so that the proposed Sealing unit 1 is fixed to the rotor housing.
  • Counter disc 6 and carrier plate 10 each have an opening whose diameter at least the Rotor shaft of the spinning rotor can accommodate, but advantageously far larger is trained.
  • the sealing disk 2 however, has only one opening, which is slightly larger than the diameter of the shaft, this to Closely encloses sealing purposes. Since the sealing disc 2 on the elastic Element is held displaceably on the edge 5 of the support plate 10, centered the rotor shaft (not shown), the sealing disc 2 automatically.
