Abstract

In an open-end spinning rotor with a rotor cup, and with a rotor shaft, through which the spinning rotor is supported in a bearing, the rotor shaft and the rotor cup are detachably connected to each other through a coupling device. The coupling device includes a positive-locking connection for the transmission of the turning moment between the rotor cup and the rotor shaft, along with a magnetic device for the axial connection of the rotor shaft and the rotor cup. The rotor shaft features at least one projection with a one turning moment-transmitting area, which engages in a recess of the rotor cup with a turning moment-transmitting counter-area. A socket for a permanent magnet is arranged on the rotor cup.
