Embodiment Construction

[0019] figure 1 The spinning station 1 of an open-end rotor spinning machine is shown schematically. The control device 4 is used to control the spinning process of the spinning station 1 .

[0020] Such as figure 2 As shown, the rotor spinning device 3 arranged on the spinning station 1 includes a spinning rotor 16, the rotor cup 10 of which rotates at a relatively high speed in the rotor housing 9. The spinning rotor 16 is driven by an electric independent drive 20 . The spinning rotor 16 is mounted contact-free both radially and also axially in a magnetic bearing by means of its rotor shaft, which is embodied as a guide roller 11 of the separate drive 20 . During spinning, the rotor housing 9 is closed by a pivotably mounted cover 14 . Cover 14 and rotor housing 9 have a locking device for opening and closing, which can be actuated not only by the service unit but also by the operator.

[0021] figure 2 The illustration in FIG. 2 shows a sectional view of the rotor ...

Abstract

The device (3) has a rotor housing (9) actuated with lower pressure, and a rotor cup (10) arranged in the rotor housing. A communication port (17) is formed between the rotor housing and a drive housing (15) that includes an aperture (18) to form an air-permeable connection to an environment and is provided with a filter (19) for cleaning air flowing from the environment into the drive housing. The aperture is dimensioned with the filter such that predetermined spinning low pressure does not fall below during actuation of the rotor housing with low pressure.

Description

technical field [0001] The invention relates to a spinning device of a rotor spinning machine with a spinning rotor, a separate drive, a rotor housing, a drive housing and a connection opening, wherein the spinning rotor has a rotor cup and a rotor rod, the independent drive device is configured to drive the spinning rotor in rotation and is operatively connected to the rotor rod for this purpose, the rotor housing can be subjected to negative pressure and the rotor cup is arranged in the rotor housing In the body, the independent drive device is arranged in the drive device housing, the connection opening is provided between the drive device housing and the rotor housing, and the rotor rod extends through the connection opening And it is designed such that a pressure compensation takes place between the rotor housing and the drive housing. Background technique [0002] EP0972868A2 discloses an independent drive of a spinning device. The spinning rotor is supported with it...
