Abstract:
A bearing for a shaft of a spinning rotor of an open-end spinning machine, comprising;(a) two axially spaced-apart pairs of magnets, one magnet of each pair of magnets disposed on the shaft and the other magnet of each pair of magnets disposed on a stator housing of the open-end spinning machine, each magnet of each pair of magnets being disposed in respective dispositions rotationally symmetrical to the axis of the rotor shaft, said pair of magnets magnetically supporting the rotor shaft both axially and radially without contact therewith, the magnets of each pair of magnets having nonidentical magnet poles facing one another,(b) an electromagnetic center position regulator for maintaining an axial center position of the rotor shaft during operation of the open-end spinning(c) an axial interception bearing disposed at an end of the rotor shaft for engagement therewith in the event of an energy failure of the open-end spinning machine.
