Abstract

See full text

An open-end spinning rotor (1), comprising a rotor shaft (4), a rotor cup (2) and a coupling device (3) releasably connecting the rotor shaft (4) and rotor cup (2). The coupling device (3) has locking bodies (6), arranged in a holding element (5) and lock the rotor cup (2) and the rotor shaft (4) in the axial direction under centrifugal force during operation of the open-end spinning rotor (1). A resilient element (7) is associated with the locking bodies (6) and cooperates with the locking bodies (6) such that the locking bodies (6) also lock the rotor cup (2) to the rotor shaft (4) in the axial direction at a standstill. The holding element (5) is configured as a pin which is formed such that it produces a positive shaft-hub connection between the rotor shaft (4) and rotor cup (2) in conjunction with a correspondingly formed hub (8).
