Abstract
A rotor spinning device with a contactless passive radial bearing for the spinning rotor. A damping device exerts magnetic forces on the rotor shaft (9) of the spinning rotor by means of operating elements (11, 12), and in this manner damps radially directed oscillations of the spinning rotor. The stationary operating elements (11, 12), which are embodied as magnetic elements, act directly on a magnetic element (8), which is fixedly connected with the rotor shaft (9), wherein the magnetic element (8) is an operative element of the passive bearing of the spinning rotor. A rapid, effective damping of the oscillations is possible without large expenditures.
Claims7
A rotor spinning device comprising a contactless, passive, radial bearing for the spinning rotor and a damping device external the passive radial bearing for damping radially directed oscillations of the spinning rotor, the damping device comprising a sensor arrangement, a control arrangement and an operating arrangement, the operating arrangement having at least two stationary magnetic operating elements arranged to act directly at least at one active site on a permanent magnet fixedly connected with the rotor shaft for rotation therewith, the rotating permanent magnet comprising an operative element of the passive bearing of the spinning rotor.
