Embodiment Construction

[0059] in accordance with figure 1 The open-end spinning device shown in the side view of the example embodiment of the invention is indicated with the reference numeral 1 . As known, the open-end spinning device 1 comprises a rotor housing 2 in which the rotor of the spinning cup rotates at high speed during the spinning operation. The spinning rotor 3 is thus supported in the drive and bearing arrangement 32 . This means that the spinning rotor 3 is supported by its rotor shaft 4 in bearing gussets supporting disc bearings 5, which support disc pairs 7 (as will be referred to below figure 2 explained in detail) is pressurized, for example, by means of a tangential belt 6 connected to the drive reel 25 of the single drive 26 .

[0060] The axial positioning of the rotor shaft 4 is carried out by means of a magnet bearing arrangement 18 which is arranged between the front support disc 7A and the rear support disc 7B of the pair of support discs 7 in the region of the suppor...

Abstract

The invention relates to an open end rotor spinning device (1) with a spinning rotor (3), which is mounted with its rotor shaft (4) in the gore of a support disk bearing (5) and is axially positioned by means of a magnetic bearing device (18), and a drive and storage device 32) for the rotary application of at least one of the pairs of support disks (7) of the support disk bearing (5). According to the invention, the magnetic bearing device (18) is arranged between the front (7A) and rear (7B) supporting disks for the axial fixing of the rotor shaft (4) in the region of the gusset of the support disk bearing (5).

Description

technical field [0001] The present invention relates to an open-end rotor spinning device (open-end rotor spinning device), the open-end rotor spinning device comprises: a spinning rotor (spinning rotor), the spinning rotor is supported by the angle bracket of the disc bearing ( The rotor shaft of the spinning rotor in a gusset is supported and axially positioned by magnet bearing means; and a drive and bearing means for rotationally pressing at least one of the pair of support discs of the support disc bearing. Background technique [0002] Modern open-end rotor spinning devices today have to comply with a number of requirements which are necessary for the construction of such textile machines. Such open-end rotor spinning machines not only need to be able to produce high-quality yarn as required and at any time, but such textile machines also need to be operated as economically as possible. This means that the textile machine is characterized by a high output, wherein the...
