Abstract: An open-end spinning device for an open-end spinning machine includes a rotor housing and a spinning rotor having a rotor cup accommodated in the rotor housing. A drive for the spinning rotor is arranged in a drive housing. At least one receptacle for a cover element that closes the rotor housing during spinning operations is provided. The rotor housing includes an adjustable stop for the cover element, the stop positioning the cover element in an axial direction of the spinning rotor.

Abstract: An open-end spinning device for an open-end spinning machine includes an individually drivable spinning rotor having a rotor cup accommodated in a rotor housing. An individual drive for the spinning rotor arranged in a drive housing. A receptacle for a cover element that closes the rotor housing during spinning operations is provided. The rotor housing defines a central support part fixable to a machine frame of the open-end spinning machine. The rotor housing is formed as one piece with the drive housing and the receptacle for the cover element.

Abstract: A support disk for a suspension for a spinning rotor (2) of an open-end spinning device features a base body (8) and a thrust ring (9) with a running surface (10) attached on an outer circumference of the base body (8), whereas the running surface (10) has a crowned outer contour in the axial section. The running surface (10) features at least two partial sections (11), between which at least one groove-shaped recess (12, 14, 16) is formed. A suspension for a spinning rotor (2) of an open-end spinning device contains support disks (3) arranged in pairs forming a wedge slit, whereas the spinning rotor (2) can be mounted with its shaft (1) in the wedge slit, and whereas at least one of the support disks (3) is formed as described above.
