Definitions

  • the present invention relates to an open-end spinning rotor having a rotor cup, in which a fiber material is spinnable, and having a rotor shaft, via which the spinning rotor in a storage, in particular in a magnetic bearing, can be supported.
  • the rotor shaft and the rotor cup are releasably connected together via a coupling device.
  • the coupling device includes a positive connection for torque transmission between the rotor cup and the rotor shaft and a magnetic device for the axial connection of the rotor shaft and rotor cup.
  • the DE 38 15 182 A1 describes a spinning rotor with such a coupling arrangement.
  • the DE 38 15 182 A1 provides, at the end of the rotor shaft to arrange a coupling shell with a recess or sleeve, in which a correspondingly complementary trained pin, which is arranged at the back of the bottom of the rotor pot, engages.
  • the torque transmission from the rotor shaft to the rotor pot is to be done by a positive connection of the two coupling parts together.
  • According to a second embodiment may be provided instead of a large, central pin and a plurality of smaller pins which engage in recesses of the coupling shell.
  • To hold the rotor pot is a permanent magnet, which is inserted into the clutch disc on the rotor shaft.
  • the clutch assembly is relatively complex to produce and also relatively large and heavy, which is disadvantageous at today's high speeds.
  • the EP 1 156 142 B1 shows a spinning rotor, which is already provided for an open-end spinning device with a magnetic bearing assembly.
  • the coupling device includes a receiving sleeve arranged on the shaft of the spinning rotor, in which a hexagon socket is arranged.
  • a cylindrical guide projection is formed, which engages in the receiving sleeve of the rotor shaft.
  • an external hexagon is an external hexagon, which engages in the hexagon socket in the sleeve of the rotor shaft.
  • a permanent magnet is also disposed within the rotor shaft, which is to take over the axial securing of the coupling device.
  • the production of the spinning rotor with the additional guide projection and the additional receiving sleeve is also relatively expensive.
  • Object of the present invention is to propose an open-end spinning rotor with a coupling device, which has a simple and easy to maintain in construction.
  • the coupling device includes a positive connection for torque transmission and a magnetic device for the axial connection of the rotor shaft and rotor cup. It is now provided to arrange the coupling device with its two coupling components directly to the rotor shaft or the rotor cup without the interposition of other components.
  • the assembly of the open-end spinning rotor is thereby particularly simple, since only two parts rotor shaft and rotor cup must be connected to each other and possibly even the permanent magnet must be used.
  • the open-end spinning rotor can therefore be used particularly advantageously also in open-end spinning devices with high speeds of more than 130,000.
  • the rotor shaft has at least one projection with at least one torque-transmitting region, which engages in at least one corresponding recess of the rotor cup with at least one torque-transmitting counter region.
  • a receptacle for a permanent magnet is arranged at the rotor cup. The fact that the permanent magnet is arranged on the rotor cup, it is possible in a particularly simple and effective way to remove it after its lifetime and replace it with a new permanent magnet. A complex disassembly of the rotor shaft from the storage of the open-end spinning device is not required for this purpose.
  • the permanent magnet is particularly accessible and simple interchangeable.
  • the permanent magnet is located on the wear part of the spinning rotor, namely the rotor cup, which must be replaced anyway after a certain time. It has been shown that such magnets often have a comparatively short life and therefore must be replaced. This is now easily possible by the arrangement of the permanent magnet on or in the easily replaceable rotor cup, since the magnet is easily accessible.
  • a particularly good accessibility and thus a particularly simple interchangeability of the permanent magnet results when it is arranged in the axial extension of the recess for the projection of the rotor shaft. At the same time, this results in a particularly good axial connection between the rotor shaft and the rotor cup.
  • a simple production and a simple assembly of the open-end spinning rotor is made possible when the receptacle for the permanent magnet is formed by a hole in the rotor cup.
  • a hole in the rotor cup Preferably, such a bore is located in the bottom of the rotor cup, so that the permanent magnet can be easily introduced into the receptacle from the opening of the rotor cup.
  • one or more permanent magnets within the confederation of the rotor cup so that they are in the assembled spinning rotor next to the projection of the rotor shaft.
  • an annular permanent magnet may also be arranged in the collar of the rotor cup, which surrounds the projection of the rotor shaft when the spinning rotor is mounted.
  • the at least one projection of the rotor shaft at least at its the rotor cup end facing a cylindrical outer contour. In this way, a good centering of the rotor cup can be achieved to the rotor shaft and imbalances are avoided.
  • the at least one projection of the rotor shaft at least in sections, an elliptical outer contour.
  • the projection of the rotor shaft can either have an elliptical outer contour over its entire length or can only have a section with an elliptical outer contour.
  • the elliptical outer contour in this case forms the at least one torque-transmitting region.
  • the at least one projection of the rotor shaft includes a first, the rotor cup facing portion and a second, facing away from the rotor cup end shaft portion facing portion.
  • the section facing the shaft end contains the at least one torque-transmitting region, which may be designed, for example, as a torque-transmitting surface or edge.
  • the at least one projection or a portion of the at least one projection of the rotor shaft has at least one groove which contains the at least one torque-transmitting region. This can be produced in a favorable manufacturing technology by milling.
  • the second section includes a wrench size or an elliptical outer contour. This in turn then forms the torque-transmitting region, here in the form of a torque-transmitting Area. If the second section contains a wrench size, then both the wrench size at the second section of the projection and the corresponding counterpart area or counter surface at the rotor cup can be produced in a particularly simple manner. However, it is also possible to provide only a single torque transmitting area on the second section.
  • the first section has a cylindrical outer contour.
  • the cylindrical outer contour can be made in a simple manner centering.
  • the rotor shaft can be fixed in the rotor cup, for example by a press fit.
  • the at least one recess of the rotor cup includes a through-hole, in particular a cylindrical through-hole. It is particularly advantageous if the receptacle for the permanent magnet in the cylindrical through hole is arranged or formed directly through the cylindrical through hole. At the same time, this makes it possible to achieve a particularly good axial hold, since with a mounted spinning rotor the projection of the rotor shaft and the permanent magnet can touch each other directly.
  • the through-hole can also be elliptical or oval. In this case, in turn, the inner, elliptical or oval lateral surface of the through-bore forms the at least one torque-transmitting counter-surface or the at least one torque-transmitting counter-region.
  • the at least one recess of the rotor cup includes a first, in particular cylindrical portion, in which engages the first portion of the projection of the rotor shaft, and a second portion, which the at least one torque-transmitting counter-region includes and cooperates with the first portion of the projection of the rotor shaft.
  • first, in particular cylindrical portion in which engages the first portion of the projection of the rotor shaft
  • second portion which the at least one torque-transmitting counter-region includes and cooperates with the first portion of the projection of the rotor shaft.

Likewise, three or more sections may be provided. In this case, the at least one torque-transmitting region or counter-region does not necessarily have to be arranged on the first section facing away from the rotor cup.
  • the second section of the recess includes at least one groove, which preferably extends over the entire width of the collar of the rotor cup.
  • the preparation of the rotor cup or the spinning rotor is thus possible in a particularly simple manner by milling the groove or grooves.
