Problems solved by technology

[0013] Open-end spinning devices with such relatively low-cost rolling bearing mechanisms have proven themselves in the context of open-end spinning machines with limited rotor speeds, but have the following disadvantage: The gap seals arranged in the area of ​​the bearing housing are only Dynamic support of the spinning rotor functions as specified
[0015] Such deposits lead over time to functional disturbances on dirty rolling bearing mechanisms and even complete stoppages of the associated open-end spinning device

Embodiment Construction

[0043] figure 1 A schematic side view of a station of the open-end spinning machine 1 is shown. Such an open-end spinning machine 1 has, as is known, a plurality of such identical stations 2 , each of which is equipped with an open-end spinning device 3 and a winding device 33 .

[0044] In the open-end spinning device 3 , the fiber sliver 34 pre-fed in the spinning can 28 is spun into a yarn 30 , which is then wound up on a winding device 33 into a cross-wound bobbin 22 .

[0045] In this case, the winding device 33 has, as usual, a creel 21 for rotatably holding the bobbins of the cross-wound bobbin 22 , a bobbin drive roller 23 and a yarn traversing device 26 .

[0046] In the embodiment shown, the winding device 33 also has a lifting mechanism 7 for lifting the cross-wound bobbin 22 off the bobbin drive roller 23 . The lifting mechanism 7 is, for example, in the form of a thrust piston transmission, which is connected to a source of overpressure (not shown) via a pneumat...

Abstract

The invention relates to a free-end spinning device and a sealing member for an open-end rotor spinning device. The free-end spinning device comprises a spinning rotor which rotates during the spinning operation at high speed in a negative pressure-bearing rotor housing to which a bearing housing is connected. The bearing housing has a rotor supporting mechanism, which comprises lubricated front and rear roller bearing mechanisms, where the rotor supporting mechanism is supported. The roller bearing mechanisms is sealed, and a gap sealing mechanism seals the roller bearing mechanisms under dynamic supporting mechanism. According to the invention, at least the gap sealing mechanism (41) of a rear roller bearing mechanism (Figure 5B) is provided with additional elastic sealing member (42A, 42B) and corresponds to corresponding sealing surface (46, 48) under static bearing state. The bearing roller mechanisms (5A, 5B) are also sealed in the static supporting condition of the spinning rotor (4) relative to the ambient atmosphere.

Description

technical field [0001] The present invention relates to open-end spinning devices and seals. Background technique [0002] With regard to the installation of the spinning rotor in an open-end spinning device of an open-end rotor spinning device, a large number of embodiments are known which are partly different and which are partly explicitly described in the patent literature. [0003] For example, in the prior art, not only the free end spinning device in which the spinning rotor is installed in a non-contact manner by means of a magnetic bearing mechanism or pneumatic bearing is disclosed, but also the free end of the spinning rotor mechanically supported in the bearing mechanism is disclosed. Spinning device. [0004] With regard to mechanical spinning rotor bearings, for example so-called support plate bearings are widely used, in which the spinning rotor is supported with its rotor shaft in the support guide rollers of two rotatably mounted support plate pairs, which ...
