Open nend - rotor spinning device with a spinning rotor, which with its rotor shaft is mounted in the nip of a support disk bearing

摘要

The present invention relates to an open nend - rotor spinning device (1) with a spinning rotor (3), which with its rotor shaft (4) in the nip of a support (5) and mounted by means of a magnetic bearing device (18) is positioned axially, as well as a drive - and bearing device (32) for the rotational actuation of at least one of the pairs of support disks (7) of the support disk bearing (5).According to the invention, it is provided that the magnetic bearing device (18) for the axial fixing of the rotor shaft (4) in the region of the nip of the support disk bearing (5) between the front (7a) and the rear (7b) of the support disks arranged and is designed in such a way that the rotor shaft (4) by means of the magnetic bearing device (18) with a in the direction of the support disks (7a, 7b) acting contact force (f) is acted upon.
