摘要： 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.

摘要： An opening roller housing (1) for an opening roller (2) of an open-end spinning machine (3) has a feed opening (4) for feeding a fiber material (5) into the opening roller housing (1), a delivery opening (6) for drawing opened individual fibers (7) out of the opening roller housing (1), a trash removal opening (8) for extracting trash (9) out of the fiber material (5), and an inner circumferential wall (10), which surrounds the opening roller (2) during operation and has a fiber-guiding area (11), which extends from the feed opening (4), over the trash removal opening (8), and up to the delivery opening (6). The opening roller housing (1) includes a hollow cylindrical ring (12). The hollow cylindrical ring (12) is designed as a self-supporting component, which is directly fastenable on a carrier part (13) of the open-end spinning machine (3) and includes the inner circumferential wall (10) having the fiber-guiding area (11) as well as the feed opening (4), the delivery opening (6), and the trash removal opening (8). An open-end spinning machine (3) includes an opening roller housing (1) of this type.

摘要： A rotor cup for spinning a fiber material includes a coupling device to detachably connect the rotor cup to a rotor shaft. The coupling device includes a connecting means for transfer of torque from the rotor shaft to the rotor cup and for axial securing of the rotor cup on the rotor shaft, and a centering means for centering the rotor cup on the rotor shaft. The centering means may include a cone-shaped extension or cone-shaped receiver defined on the rotor cup. The connecting means may include an extension on the rotor cup, with the centering means being a centering element separate from the connecting means and defined as one of a cylinder pin fixed in the rotor cup or a centering bore arranged in the rotor cup. An open end spinning rotor may include the rotor cup.

摘要： A method for operating a spinning device of a rotor spinning machine, and associated rotor spinning machine are provided in which a spinning rotor includes a rotor cup and a rotor shaft that is set into rotation with the aid of a drive situated in a drive housing. The drive is operatively connected to the rotor shaft, and the rotor shaft is supported in the drive housing by a bearing. The rotor cup is situated in a rotor housing to which vacuum is applied, and the rotor shaft extends between the drive housing and the rotor housing through a connection opening such that when a vacuum is drawn in the rotor housing during a spinning process, a vacuum is also drawn in the drive housing. Compressed air is feed into the drive housing via an air inlet at intervals to clean one or both of the drive housing and the bearing.

摘要： A method for producing a rotor cup for an open-end spinning rotor includes forming separating structures on a front-side rim of the rotor cup for breaking up and preparing a yarn end for piecing. The separating structures are formed by a non-mechanical manufacturing method without contact between the front-side rim and a mechanical forming tool. A rotor cup formed in accordance with the method is also provided.

摘要： The invention relates to a method for producing a rotor cup (10) for an open-end spinning rotor (1), with which a front-side edge (16) of the rotor cup (10) is provided with separating structures (17) for breaking up and preparing a yarn end (5a) for spinning in, whereas the separating structures (17) are deposited by a non-mechanical manufacturing method, in particular by a non-mechanical ablation method. The invention also relates to a rotor cup (10) for an open-end spinning rotor (1) with an inner rotor wall (12) and an outer rotor wall (13), a rotor bottom (14) and a front-side edge (16) opposite the rotor bottom (14), which is provided with separating structures (17) for breaking up and preparing a yarn end (5a) for spinning in, whereas the separating structures (17) feature a surface with a micro-profile (20).
