Definitions

  • the present invention relates to a method for checking an assembled state of a spinning rotor, which comprises a rotor shaft with a shoulder and a rotor cup detachably connected to the rotor shaft.
  • the spinning rotor is mounted in a magnetic bearing in an open-end spinning device which can be closed with a cover element on the front.
  • the magnetic bearing has means for adjusting an axial position of the rotor shaft, means for detecting the axial position and at least one front axial catch bearing for the shoulder of the rotor shaft.
  • both the radial position and the axial position of the spinning rotor are permanently recorded and controlled accordingly.
  • Both the position control for passive magnetic bearings and the actively controlled magnetic bearings are dependent on a constant power supply. In order to avoid damage to the magnetic bearings in the event of malfunctions, therefore mechanical catch bearing provided.
  • the present invention deals with both types of magnetic bearings.
  • the spinning rotor 2 is shown in its regular axial operating position 11, in which the shoulder 5 of the rotor shaft 3 is at a first distance s0 from the front axial catch bearing 10. Likewise, the rear bearing surface 13 has a second distance h0 from the rear axial catch bearing 12.
  • the spinning rotor 2 is shown here in a correct assembly state, in which the rotor cup 4 is completely attached to the rotor shaft 3. If the spinning rotor 2 is in a correct assembly state and in its regular axial operating position 11, it has a regular gap dimension k0 to the cover element 7 of the open-end spinning device 1, as shown here.
  • the cover element 7 can contain a channel plate or a channel plate adapter that can be inserted into such a channel plate.
  • Figure 4c shows the method according to the second embodiment with the spinning rotor 2 correctly installed Figure 4a described, the spinning rotor 2 is moved to the front axial catch bearing 10 until the cover element 7 is closed. The cover element 7 is now closed (two-dot chain lines). Since the spinning rotor 2 has the correct axial length due to the correct assembly state, it is not displaced by the cover element 7. If, after the cover element 7 has been closed, the spinning rotor 2 is moved from its axial stop, here the front catch bearing 10, into its regular axial operating position 11, the first travel path s therefore corresponds exactly to the predefined, first distance s0.
