Abstract
An open-end spinning rotor (1), comprising a rotor shaft (2), a rotor cup (3) and a coupling device (4) with a receiving element (5) connected to the rotor shaft (2) and an axle element (6) connected to the rotor cup (3). The coupling device (4) comprises three clamping bodies (7, 8, 9), arranged between a contour (10) of the receiving element and a contour (11) of the axle element. The contour of the receiving element, the contour of the axle element and the clamping bodies are configured such that by driving the rotor shaft, a relative rotational movement is produced between the receiving element and the clamping bodies and the axle element, in that owing to the relative rotational movement, the clamping bodies are clamped between the contour of the axle element and the contour of the receiving element to non-positively transmit a drive torque.
