Abstract

The rotor (1) has a rotor cup (2) and a coupling setting (3) interconnected with a rotor shank (4). The coupling setting is provided with a locking part (5) for axial locking of the rotor cup. A transfer part (9, 10) transfers torque of the rotor shank to the rotor cup. A centering part centering the rotor shank and the rotor cup and provided with a cylindrical drilling and a guide set up. A flexible arrangement is arranged between the cylindrical drilling and the guide set up. Distance between the cylindrical drilling and the guide set up is less than 0.1 mm.

Description

technical field

[0001] The present invention relates to an open-end spinning rotor, which comprises: a rotor shaft, a rotor cup and a connecting device, the connecting device connects the rotor shaft and the rotor cup in a releasable manner . The connecting device has a locking device for axially locking the rotor cup, a transmission device for transmitting torque from the rotor shaft to the rotor cup in a form-fitting manner, and additionally for connecting the rotor shaft to the rotor cup. A centering device for centering the rotor cup. The centering device comprises a cylindrical bore and a guide appendage corresponding to the cylindrical bore and capable of being introduced into the cylindrical bore. Background technique

[0002] A spinning rotor that has been inserted into an open-end rotor spinning machine must be able to be replaced if necessary, for example in the event of wear or in order to produce a different type of yarn on the rotor spinning machine. Dependin...
