<p>The present invention relates to an open-end spinning rotor (la, lb, lc), comprising a rotor shaft (4a, 4b, 4c), a rotor cup (2, 2c) and a coupling device (3a, 3b, 3c), to releaseably connect the rotor shaft (4a, 4b, 4c) and the rotor cup (2, 2c), wherein the coupling device (3a, 3b, 3c) has locking means (5, 6) for the axial locking of the rotor cup (2,2c), transmission means (9,10,11,12) for the positive transmission of a torque from the rotor shaft (4a, 4b, 4c) to the rotor cup (2, 2c) and, additionally, centring means for centring the rotor shaft (4a, 4b, 4c) and rotor cup (2, 2c), wherein the centring means comprise a cylindrical bore (8, 8c) and a guide attachment (7, 7c) corresponding thereto, which can be introduced into the cylindrical bore (8, 8c. According to the invention, the cylindrical bore (8, 8c) and the guide attachment (7, 7c) have a clearance fit and the centring means comprise a resilient arrangement (13, 14, 15b, 15c), which is located between the cylindrical bore (8, 8c) and the guide attachment (7,7c).</p> |
