Definitions

  • the present invention relates to an open-end spinning rotor which is arranged on a rotor shaft.
  • the object of the present invention is therefore to produce a simple and economically feasible, secure connection between the spinning rotor and the rotor shaft, this connection also being intended to be easily removed again so that the spinning rotor can be replaced independently of its shaft.
  • the rotor shaft carries a collar and the open-end spinning rotor is pressed against the collar by means of an elastic tensioning disk.
  • the tension disk is placed on the rotor shaft so that its central section is pressed against the rotor base from the open rotor side, so that the tension disk, the outer edge of which is supported on the rotor base, assumes a flat shape.
  • the end of the rotor shaft located inside the rotor and the elastic tension spring clamped on this end are arranged concentrically with the open-end spinning rotor and are themselves in the form of a rotating body, so that they lie smoothly inside the rotor, so that they do not interfere with the air flow or cause Fix fibers or dust.
  • the rotor shaft and tensioning disk protrude only a very small amount from the rotor base, so that the rotor shaft and the tensioning disk do not protrude into the circumferential area of the thread being drawn off.
  • the attachment of the tension disc on the rotor shaft and thus the manufacture of the attachment of the open-end spinning rotor on its shaft is very simple. After the open-end spinning rotor has been placed on the rotor shaft and after the tensioning disk has been placed, the latter is simply pressed in the direction of the collar, which means that the spinning rotor is also held securely in contact with the collar. The tension disc is pressed flat and thereby tensioned.
  • the tensioning disc is supported with its outer edge on the rotor base and with its inner edge on the rotor shaft.
  • the collar can in principle also be provided in the interior of the rotor at the end of the rotor shaft, so that the tension disk, e.g. a disc spring, exerts an axial pressure on the spinning rotor from the outside of the spinning rotor.
  • the tension disk e.g. a disc spring
  • the solution according to the invention is extremely simple. While tensioning disks usually have the task of applying relatively large spring forces in a relatively small space and also have a relatively large clearance in the radial direction, the fits between the rotor shaft and tensioning disk are selected very closely according to the invention, so that the tensioning disk is supported on the rotor shaft and thus the Spinning rotor holds in a defined position on the collar. This exact positioning also does not result in imbalances, but an exact concentricity of the spinning rotor is guaranteed.
  • the collar can be an integral part of the rotor shaft.
  • the collar is preferably not designed as an integrated component of the rotor shaft, but is releasably attached to this rotor shaft.
  • the federal government can be designed differently.
  • the collar is designed as a second elastic tensioning disk which is placed on the rotor shaft and tensioned in the opposite arrangement to the first tensioning disk.
  • the fastening connection between the open-end spinning rotor and the rotor shaft is produced in a similar manner to that described above.
  • this single drive is expediently fastened to the rotor shaft in the manner shown above by having the bottom of a rotor between the collar and the tensioning disk, which part of this single drive for Open-end spinning rotor is.
  • a centering section is provided on the rotor shaft for receiving the tensioning disk and the open-end spinning rotor, which is offset in a suitable manner from the rotor shaft, for example by 'a different diameter or also by a collar ring arranged on the rotor shaft.
  • the rotor shaft, at its end located in the open-end spinning rotor has a collar integrated with the rotor shaft and the tensioning disk must therefore be threaded onto the rotor shaft from the end of the rotor shaft, which faces away from the open-end spinning rotor, the diameter of the Centering section larger than the diameter of the rotor shaft. This makes it easier to attach the open-end spinning rotor to the rotor shaft. In addition, it is cheaper to secure spring washers with a large diameter and a small diameter.
  • the subject of the invention enables simple mounting of the spinning rotor on the rotor shaft.
  • the open-end spinning rotor can be produced as desired in a cutting process or in a non-cutting process.
  • the type of fastening of the spinning rotor on its shaft according to the invention is the prerequisite for being able to quickly remove the spinning rotor from its shaft and to be able to replace it with a new spinning rotor. This considerably simplifies storage, since only the spinning rotors to be replaced and not the associated rotor shafts must be kept in stock each time.
  • the open-end spinning rotor 1 shown in FIG. 1 is formed from sheet metal without cutting and has a flat rotor base 10 with a central opening 11.
  • the spinning rotor 1 sits on the end of a rotor shaft 20, from which a centering section 2 projects through this opening 11 into the rotor interior 12.
  • the outer diameter of the centering section 2 and the diameter of the opening 11 are matched to one another so that the spinning rotor 1 is fixed radially exactly to the centering section 2.
  • a support ring 30 is provided at a distance from the end located in the rotor interior 12, the collar 3 of which serves as a bearing for the spinning rotor 1.
  • This support ring 30 is fastened to the rotor shaft 20 or the centering section 2 by means of a clamping screw (not shown) or by pressing, shrinking or the like.
  • the collar 3 thus surrounds the centering section 2 in a ring shape.
  • a tensioning disk 4 is arranged, which presses the spinning rotor 1 against the collar 3 due to its prestressing.
  • the tensioning disk 4 is placed on the end of the centering section 2 in such a way that the outer edge 40 is supported on the rotor base 10, while the inner edge 41 is at a distance from the rotor base 10.
  • the inner edge 41 of the tensioning disk 4 is pressed against the rotor bottom 10 with a suitable tool from the inside of the rotor 12, whereby the inner edge 41 of the tensioning disk 4 clamps on the centering section 2 and on a return is prevented from relaxing.
  • the tensioning disk 4 thus holds the spinning rotor 1 firmly in contact with the collar 3. This is achieved by a suitable choice of the outer diameter of the centering section 2 and the inner diameter of the tensioning disk 4. These two diameters are matched to one another in such a way that they form an interference fit for the tensioning disk 4 on the centering section 2.
  • the required exact inside diameter of the clamping disk 4 is achieved, for example, by fine stamping.
  • the spinning rotor 1 is later to be removed from the rotor shaft 20, for example because the spinning rotor 1 has become unusable due to wear or a spinning rotor 1 of a different size or geometry is to be provided instead, it is sufficient to center the section 2 from the spinning rotor 1 from the inside of the rotor 12 press out and thereby loosen the tension plate 4. This can easily be done with the usual simple printing devices. In operation, there are practically no large axial forces on the spinning rotor 1, but mainly radial forces. There is therefore no danger that the spinning rotor 1 will become detached from the centering section 2 during the spinning operation.
  • the collar 3 can be designed differently. So the clamping disc 4 and the collar 3 can be spatially interchanged.
  • a ring can be used as a collar, which is located within the spinning rotor 1 and is worked on or attached to the end of the centering section 2.
  • the tensioning disk presses the spinning rotor 1 against the collar from the outside.
  • FIG. 2 shows another advantageous embodiment of a collar 3.
  • the collar 3 is formed by a second clamping disk 31, which is arranged on the centering section 2 of the rotor shaft 20.
  • the clamping disks 4 and 31 are so placed on the centering section 2 that its curved middle section with the inner edge 41 or 32 is at a distance from the rotor base 10, while its outer edge 12 or 33 is already in contact with the rotor base 10.
  • the tensioning disk 31 is thus arranged outside the spinning rotor 1 in the opposite arrangement to the tensioning disk 4 arranged in the interior of the rotor on the centering section 2.
  • the spinning rotor 1 can, as a comparison of Figures 1 and 2 shows, be made without cutting or cutting. But the bearing or the drive of the spinning rotor 1 can also be designed differently. For example, an individual drive can be provided for each spinning rotor 1, which has a rotor 5 connected to the spinning rotor 1, which carries permanent magnets 50 on its inner wall (FIG. 3). These permanent magnets 50 are part of an electric motor (not shown).
  • the centering section 2 is in this training Part of a bearing shaft 21 which forms the rotor shaft and which supports and supports the entirety of the spinning rotor 1 and rotor 5.
  • the spinning rotor 1 is fastened here in the same manner as was explained with reference to FIG. 2.
  • the base 51 of this rotor 5 is only arranged between the tension disk 4 in the rotor interior 10 and the tension disk 31 forming the collar 3.
  • the collar 3 - which in principle can also be configured differently from FIG. 3 - and the tensioning disk 4 thus serve not only to fasten and clamp the spinning rotor 1, but also to fasten the rotor 5 to the journal 21. The fastening takes place in the previously described manner.
  • rotor shaft 20 The design of the rotor shaft 20 is not tied to the designs shown. Rather, each element is understood independently of its shape and length, which serves to support the spinning rotor 1.
  • rotor shaft also includes tubular and sleeve-like configurations.
  • the rotor shaft is designed in the form of a bearing journal 21, which is relatively small and only has a centering section 2 with an enlarged diameter in its area, which serves to fasten the spinning rotor 1 and the rotor 5.
  • the bearing pin 21 thus has a small mass, but nevertheless has, due to the larger diameter of the centering section compared to the diameter of the bearing pin 21, such a large supporting surface for the clamping disk 4 and 31 that the spinning rotor 1 and the rotor 5 are held securely in a radial arrangement for journaling is guaranteed.
  • the rotor shaft 20 or journal 21 is thus to be matched solely to the requirements of the bearing, while the centering section 2 is to be matched to the requirements of the rotor attachment (or the attachment of a rotor 5).
  • the tensioning disk 31 must be pushed off from the end of the rotor shaft 20 or the bearing journal 21 facing away from the spinning rotor 1. This can also be accomplished more easily by the reduced diameter of the rotor shaft 20 or of the bearing pin 21 designed as a rotor shaft compared to the diameter of the centering section 2.
  • tensioning disk in the preceding description is intended to encompass all elements (for example disc springs) which, without special training or machining of the centering section 2 and the spinning rotor 1, permit the spinning rotor 1 to be fastened on the centering section 2 by prestressing. Such equivalents thus fall within the scope of the present subject matter of the invention.
