Embodiment Construction

[0073] figure 1 A schematic side view of a rotor spinning machine 1 with a spinning device 2 is shown. With the aid of the spinning device 2 , a yarn 4 can be spun from the fiber material 3 , which yarn can be wound up on a drum 14 . The spinning device 2 has a spinning rotor 5 by means of which a yarn 4 is formed from a fiber material 3 during operation of the rotor spinning machine 1 .

[0074] The spinning rotor 5 has a rotor cup 6 and a rotor shaft 7 . In order to form the yarn 4 from the fiber material 3 , the fiber material is guided into the rotor cup 6 during the rotation of the spinning rotor 5 . By means of the rotation of the spinning rotor 5, the yarn 4 is formed. The spinning rotor 5 can be driven here by a drive 11 which is designed in particular as an electromechanical single drive. The rotational speed of the spinning rotor 5 can be counted here as 150,000 1 / min or higher, so that high demands are placed on the bearing 10 of the spinning rotor 5 . Bearing ...

Abstract

According to a method for operating a spinning device (2) of a rotor spinning machine (1), a spinning rotor (5) provided with a rotor cup (6) and a rotor shaft (7) is driven to rotate by a driving device (11), which is arranged in a driving device shell (8) and is operably connected to the rotor shaft, and is supported in the driving device shell by a bearing (10,18). The rotor cup is arranged ina rotor shell (9) loaded by a negative pressure. The rotor shaft extends and goes through a connection opening (12) arranged between the driving device shell and the rotor shell, and thus during the spinning process, the driving device shell also has a negative pressure. Compressed air is fed into the driving device shell through an air supply end. Preferably, the driving device shell and/or the bearing are cleaned at intervals of adjustable time. A corresponding spinning device of a rotor spinning machine is provided with a control unit for controlling the supply of compressed air. Through the control unit, compressed air is supplied to the driving device shell through the air supply end at intervals of adjustable time, preferably.

Description

technical field [0001] The invention relates to a method for operating a spinning device of a rotor spinning machine, wherein a spinning rotor with a rotor cup and a rotor shaft is rotated by means of a drive arranged in a drive housing, wherein the drive is in operable connection (wirkverbindung) with the rotor shaft, and the rotor shaft is mounted in the drive housing via non-contact bearings (in particular magnetic bearings), wherein the rotor cup is arranged in the rotor housing, which is subject to load pressure. Furthermore, the rotor shaft extends through the connecting opening between the drive housing and the rotor housing, so that the drive housing is also under negative pressure during the spinning process. Compressed air is fed into the drive housing through the air inlet. Furthermore, the invention relates to a spinning device of a rotor spinning machine. Background technique [0002] In such spinning devices, a complete seal is not possible between the drive...
