Definitions

  • the present application relates to an open-end spinning rotor according to the Preamble of claim 1.
  • DE-A 38 15 182 is a spinning rotor known, the rotor pot with the carrier part of the rotor shaft via a Coupling arrangement is connected.
  • the Coupling made of two elastic hooks which are used when joining the rotor pot and Engage the rotor shaft in an undercut on the rotor cup. This The undercut is in the form of an oblique surface.
  • the coupling arrangement is in the essentially attached to the rotor plate. It consists of one Locking element formed in a perpendicular to the rotor axis Bore is guided.
  • the Locking elements unlocked by a spring.
  • the rotor pot is replaced by a Magnets held on the carrier part or rotor shaft. If the open-end spinning rotor in Offset rotation, the locking elements emerge from the centrifugal forces Holes in which they are guided out and lock rotor pot and that this receiving carrier part.
  • DE-A 43 42 539 is an open-end spinning rotor known, in which the rotor pot on a supporting and driving it Base body, which is designed as an electric rotor, is fastened in that a kind of screw connection is provided.
  • the coupling Due to the inventive design of the proposed open-end spinning rotor according to claim 1 is by the use of an elastic element from which at least one of the parts of the clip connection is received, that the coupling has the necessary deformability for the assembly of the rotor pot and at the same time ensures that the clip connection ensures a secure hold. At the same time it is achieved that at least part of the clip connection from elastic element itself can be included that the coupling is simple and is easy to manufacture.
  • the elastic element ensures that vibrations that are transmitted to the spinning rotor via the carrier part or Vibrations, which are generated by an imbalance of the rotor cup, that each do not burden other parts of the open-end spinning rotor with vibrations, or that the Vibrations can be damped by the elastic element.
  • the elastic Element also has the advantage that the rotation of the spinning rotor during operation the resulting centrifugal force ensures that the clip connection holds together even more firmly.
  • at least part of the clip connection is elastic
  • the element is encircled in a ring shape so that it is secure with a large area to be attached to the elastic element. This can be done, for example, by gluing or already happen when the elastic element is formed.
  • the elastic element made of a plastic, this can be done easily Wise and inexpensive to manufacture. It is also easy to do this with the support part or to connect with the rotor plate, for example. Also has Plastic the favorable property that it has a particularly good damping effect.
  • part of the clip connection is elastic Element encompasses a ring if it is slotted. This increases its deformability so that the rotor pot can be more easily connected to the carrier part can. It is particularly advantageous if several slots are provided.
  • the part of the clip connection attached to the rotor pot is particularly advantageous as annular groove formed, which can be easily by e.g. machining processing can be introduced into the rotor pot. Training the support part as a hub forms a further advantageous embodiment of the invention. Can be particularly easy then the carrier part e.g. be pressed onto a rotor shaft.
  • the part of the coupling that is not on the rotor pot is manufactured separately and then, for example, on the part of the open-end spinning rotor that is used for storage and ensures the drive to be pressed on.
  • This can e.g. be a rotor shaft or advantageously also the part of an electrical bearing and drive rotor.
  • the carrier part is formed with a stop on which the rotor pot is axially supported. This can ensure that the rotor plate is positioned exactly with the carrier part can be connected. Possible dimensional deviations in the This can compensate for the area of the clip connection. To do this, the rotor pot a counter surface that cooperates with the stop of the support part.
  • An elastomer is particularly suitable as the plastic for the elastic element.
  • An advantageous embodiment of the clip connection is at least a part of it Made of aluminum alloy. This makes it possible in a simple operation manufacture. It is particularly cheap because it is precise and quick to manufacture designed as an injection molded part.
  • In a particularly advantageous development of the invention connects the coupling of the rotor pot and the rotor shaft or some other type Carrier part of the rotor pot in a form-fitting manner in the circumferential direction. Thereby can advantageously be ensured that no relative movement in the circumferential direction between the rotor shaft and the rotor pot. This is especially true when accelerating of the spinning rotor and when braking it to a standstill.
  • the open-end spinning rotor 1 of Figure 1 consists of a rotor pot 11, from a carrier part 12 and a shaft 13, via which the spinning rotor 1 in a known manner, for example, via support disks, and for example, via a Tangential belt is driven.
  • the carrier part 12 consists of a hub 121, which is applied to the rotor shaft 13 by means of a press connection.
  • the hub 121 carries on its outer circumference an elastic element 2. This is with the hub 121, e.g. firmly connected by means of an adhesive connection.
  • the elastic element 2 can be made of plastic or rubber, for example. On his Outer circumference, the elastic element 2 carries part of the coupling 3, via the the rotor pot 11 is connected to the carrier part 12.
  • the clutch 3 is here from the nose 31, which has a circumferential groove 32, which is attached to the rotor pot 11, cooperates.
  • the clutch 3 is designed as a clip connection, so that the attachment of the rotor cup 11 on the support member 12 via simple Putting the two components together is possible.
  • the nose 31 on the elastic element 2 is arranged, the nose 31 when assembling dodge the carrier part and the rotor pot in the direction of the rotor shaft 13, whereby the edge of the circumferential groove 32 can be pushed over the nose 31, so that there is a fluid connection between nose 31 and circumferential groove 32.
  • the nose 31 is part of an annular element 310 which, like the hub 121 is firmly connected to the elastic element 2.
  • the annular element 310 can have one or more slots in the longitudinal direction of the shaft 13, whereby a greater elasticity of the annular element when Joining the rotor pot and support part results.
  • the slots can do that Cut through the annular element 310 completely, as in the lower half of FIG. 1 recognizable by the missing hatching. But the slot can just as well concern the part of the nose 31 of the annular element 310.
  • the ring-shaped Element 310 can be made of steel, for example, while the rotor pot 11 can be made of aluminum, for example. It embraces the elastic Element 2 on its outer circumference.
  • the slot also serves at the same time as an anti-rotation device acting in the circumferential direction between the rotor pot 11 and Rotor shaft 13.
  • the nose 31 does not strike one in the circumferential direction shown stop of the rotor pot 11.
  • the circumferential groove 32 may be interrupted, so that one in the axial direction the running web remains.
  • the same effect, namely the anti-rotation device can also e.g. can be achieved by means of axially extending pins, each partially in the rotor pot 11 and e.g. Engage rotor shaft 13 or hub 121.
  • the open-end spinning rotor 1 When operating the open-end spinning rotor 1, it rotates about its axis of rotation, which is the The axis of rotation of the shaft 13 is set in rotation, with speeds of up to 150,000 revolutions per minute are quite possible. It takes place as a result of Centrifugal forces that act on the clutch 3, an expansion of the annular Elements 310 instead, since the elastic element 2 yields to the centrifugal forces. Thereby becomes a particularly good connection between the nose 31 and the circumferential groove 32 accomplished. At the same time, however, the connection of the annular element offers 310 a connection via the elastic element 2 with the hub 121, which at Standstill of the spinning rotor 1 is easily released.
  • FIG. 2 shows an open-end spinning rotor which is likewise designed in accordance with the invention shown in section and only partially.
  • the elastic element 2 is here attached to a hub-shaped extension 122 of the rotor cup 11.
  • the annular element 310 of the coupling 3 is arranged on the elastic element 2, the annular element 310 of the coupling 3 is arranged.
  • the annular element 310 has a circumferential groove 32 which with a Nose 31 works together.
  • the nose 31 is part in the embodiment of Figure 2 the hub 121.
  • the carrier part 12 has a shaft 13 connected, via which the open-end spinning rotor 1 in a known manner Support discs is stored.
  • the carrier part 12 can also be used with a Bearing and drive part connected, as shown in DE-A 43 42 539.
