Abstract
An open-end spinning frame (1) having a spinning rotor (3), whose rotor shaft (4) is supported, free of axial thrust, in the bearing wedge of a support disk bearing arrangement (5) and is fixed in place by means of a magnetic axial bearing (18). The axial bearing (18) has a stationary magnetic bearing component (27) fixed on the bearing housing (26), and a rotating magnetic bearing component (44) arranged at the end of the rotor shaft and having at least two annular shoulders (46) defined by recesses (47) in the rotor shaft (4). The sharpness of the annular shoulders (46) is reduced in the area between their outer circumference (58) and the adjoining radial faces (50) of each annular shoulder, e.g., via curved or beveled surfaces in such area, and the base surfaces (49) of the recesses (47) are each connected via rounded sections (51) with the radial faces (50) of the adjoining annular shoulders (46).
