Definitions

  • the invention relates to an open-end spinning rotor with the Features of the preamble of claim 1.
  • the magnetic bearing arrangement consists of a front and a rear bearing, these bearings for their part, axially opposite each other Have permanent magnet rings.
  • One of these Permanent magnet rings are fixed on the stator, while the other permanent magnet ring with the rotor shaft circulates.
  • the rotor cup in these spinning rotors is detachably connected to the rotor shaft. This means that the rotor cup can be removed or replaced after loosening a screw connection, for example in the event of wear or when changing a lot, without the rotor shaft also having to be removed.
  • Patent literature numerous other embodiments for Coupling devices known that connect releasably allow a rotor cup to a rotor shaft.
  • DE 38 35 037 A1 relates to a mechanical-hydraulic Clamping device, with a thin-walled, expandable sleeve between the rotor shaft and rotor cup is tense.
  • the Invention based on the object, the known Coupling devices for releasably fixing a rotor cup to improve on a rotor shaft.
  • the coupling device according to the invention is not only in their constructive structure relatively simple and therefore quite inexpensive to manufacture, but also during Operation very safe at all times.
  • the magnetic device of the coupling device automatically ensures that the spinning cup in axial Direction always with maximum holding force on the rotor shaft is locked while the mechanical anti-rotation lock is over Form-fit any rotational relative movement between the prevented both components.
  • the magnet device is formed by a permanent magnet fixed to the rotor shaft and a ferromagnetic attachment on the rotor cup.
  • the permanent magnet thereby, as described in claim 3, in a arranged rotationally symmetrical receiving sleeve, which, as in Claim 4 set out about a press fit with the rotor shaft connected is.
  • the rotor shaft can be tubular be formed, the receiving sleeve with a Appropriate approach engages in the rotor shaft.
  • the setting of the rotationally symmetrical receiving sleeve on The rotor shaft adjusts by means of a press fit proven joining process that is not only simple a secure setting of the receiving sleeve and thus the Permits permanent magnets on the rotor shaft, but also ensures that there is no imbalance in the rotor shaft.
  • a form-locking element is arranged in the receiving sleeve and, in conjunction with a corresponding form-locking element at the attachment of the rotor cup, forms a mechanical anti-rotation device.
  • the form-locking element in the receiving sleeve is designed as an internal polygon, preferably as an internal hexagon.
  • the receiving sleeve of the further, as set out in claim 6, a cylindrical Hole on that with an appropriate guide approach corresponds to the rotor cup.
  • Such open-end spinning devices 1 each have a rotor housing 2, in which the rotor cup 26 of a spinning rotor 3 rotates at high speed.
  • the spinning rotor 3 is driven by an electromotive individual drive 18 and is fixed with its rotor shaft 4 in front 27 and rear 28 bearings of a magnetic bearing arrangement 5, which support the spinning rotor 3 both radially and axially.
  • the rotor housing 2 which is open towards the front, is closed during operation by a pivotably mounted cover element 8, into which a channel plate (not shown) is inserted.
  • the rotor housing 2 is also connected via a corresponding pneumatic line 10 to a vacuum source 11, which generates the spinning vacuum required in the rotor housing 2.
  • a channel plate adapter 12 is arranged in the cover element 8 or in the channel plate, which has the thread take-off nozzle 13 and the mouth region of the fiber guide channel 14.
  • a thread take-off tube 15 connects to the thread take-off nozzle 13.
  • an opening roller housing 17 is fixed on the cover element 8, which is rotatably supported to a limited extent about a pivot axis 16.
  • the cover element 8 also has rear Bearing brackets 19, 20 for mounting an opening roller 21 or a sliver feed cylinder 22.
  • the opening roller 21 is in the region of its whorl 23 a circumferential, machine-long tangential belt 24 driven while the (not shown) drive the Sliver feed cylinder 22 preferably via a Worm gear arrangement takes place on a machine-long drive shaft 25 is switched.
  • the coupling device 29 consists in detail of a magnetic device 30 and a mechanical anti-rotation device 31. That is to say, a rotor magnet 33, preferably at least in the end region, is arranged on the rotor cup 26 and is divided into two sections 38, 36 of approximately the same length. A section adjoining the rotor cup 26 is designed as a cylindrical guide projection 38, which is adjoined by an external polygon, preferably an external hexagon 36.
  • a receiving sleeve 34 set In the preferably tubular rotor shaft 4 is, via a Press fit, a receiving sleeve 34 set.
  • the receiving sleeve 34 not only has the permanent magnet ring 39 on the rotor side of the front bearing 27 of the magnetic bearing arrangement 5, but is, within the receiving sleeve 34, non-rotatable, an internal polygon, preferably an internal hexagon 35, and a permanent magnet 32 fixed.
  • the receiving sleeve 34 also has a cylindrical bore 37 which, in the installed state, corresponds to a guide shoulder 38 of the rotor cup 26, that is to say surrounds this guide shoulder 38 without play.
