Embodiment Construction

[0030] figure 1 The open-end spinning device 1 in the operating state is shown schematically in side view. That is to say, the spinning cup 32 of the spinning rotor 4 rotates at high speed inside the rotor housing 2, which is closed by the cover element 11 and is connected to the negative pressure via a flexible pneumatic line (for example via a plastic tube 3). On the source 8, the negative pressure source 8 provides the negative pressure required for spinning.

[0031] The spinning rotor 4 is mounted by means of its rotor rod 5 in the wedge-shaped gap of the disc support 6 and is axially supported by thrust bearings 9, such as permanent magnetic bearings. The spinning rotor 4 is driven by a tangential transmission belt 7 arranged longitudinally along the machine and circulating, and the tangential transmission belt 7 is in close contact with the rotor rod 5 from above in the working state. The disc support device 6 and the thrust bearing 9 are arranged on a support device ...

Abstract

The open-end spin device (1) comprises a spin rotor (4) and a bearing bracket (19) which is provided at a linear bearing (14). A sliver opening device is integrated in a cover element (11) which is connected with a storage device (10) for the spin rotor by a coupling element (23), where a rotor brake is activated.

Description

technical field [0001] The invention relates to an open-end spinning device. Background technique [0002] In connection with the stations of an open-end rotor spinning machine, different embodiments of open-end spinning devices have been disclosed and described in numerous patent applications. [0003] These known open-end spinning devices sometimes differ significantly with respect to their design. [0004] For example, German patent DE-OS 2 130 688 discloses a kind of open-end spinning device, which has two independently arranged functional parts, and these two functional parts are separately fixed on the central frame of the spinning machine respectively, and through the guide The yarn channels are functionally connected to each other. The first functional part has, for example, a spinning mechanism, in particular a spinning rotor (with associated supporting devices) rotating at high speed in a rotor housing which can be subjected to negative pressure; A fiber strip o...
