Embodiment Construction

[0020] 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 .

[0021] Such as figure 2 As shown, the rotor spinning device 3 arranged on the spinning station 1 comprises a spinning rotor 16 whose spinning cup 10 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 in a magnetic bearing both radially and also axially by means of its rotor shaft, which is embodied as 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.

Abstract

The present invention relates to a spinning device (3) of a rotor spinning machine, comprising a spinning rotor (16 ) having a rotor cup (10 ) and a rotor rod ( 11), an independent drive unit ( 20 ) which is confiugred to enable the spinning rotor (16) to rotate, a rotor housing ( 9) which can be applied with negative pressure, a drive unit housing (15), and a connecting opening (17) between the drive unit housing and the rotor housing. The rotor rod (11) passes through the connecting opening which is so configured that pressure compensation between the rotor housing and the drive unit housing is conducted. According to the invention, the drive unit housing has a second opening in an air-permeable connection to the environment, and the second opening is provided with a filter for purifying air flowing into the drive unit housing. The second opening with the filter is dimensioned so that, when the rotor housing is applied with negative pressure, the negative pressure in the rotor housing may not lower than predetermined spinning 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] EP 0 972 868 A2 discloses an independent drive of a spinning device. The spinning rotor is supported wit...
