Problems solved by technology

[0005] However, the problem of heating and wear of the support discs occurs to a greater extent with progressively higher rotor speeds
Since current spinning machines usually have more than 500 spinning stations, this also leads to a significant energy consumption in the rotor support structure

Embodiment Construction

[0023] figure 1 A schematic overview representation of an open-end spinning device with an open-end spinning rotor 2 and a support structure 1 for supporting a shaft 3 of the open-end spinning rotor 2 is shown. The support structure 1 generally contains a support base 6 carrying two support disc bearings 17 . For this purpose, the support disc bearing 17 is held in a receptacle of the bearing seat 6 . The shaft 5 of the support disk 4 is supported in the support disk bearing 17 , which in turn carries the two support disks 4 .

[0024] The two shafts 5 with their support disks 4 are now arranged in such a way that the respective two support disks 4 form a support disk pair. In this case, a wedge-shaped gap 7 is produced between the two support disks 4 of the pair of support disks, in which wedge-shaped gap 3 the shank 3 of the free-end spinning rotor 2 is accommodated. The open-end spinning rotor 2 is driven by means of a drive (not shown), such as a tangential belt, and tr...

Abstract

The invention relates to a support plate for a support structure of a handle of a free-end spinning rotor and a support structure for a handle of a free-end spinning rotor, the support plate (4) having a plate-like base body (8) (9) on the outer circumference of the lining (8), the radially outer surface of the lining providing a working surface (10) for the shank (3) of the free-end spinning rotor (2). The working surface is formed by two bearing surfaces that are spaced apart from one another in the axial direction of the support disk and have a groove-shaped recess between the bearing surfaces. The groove-like recess (12) has a width (B) which is at least as wide as or wider than the total bearing width (AB1, AB2) of the two bearing surfaces (11). The free-end spinning rotor (2) can be supported with its shank (3) in the wedge-shaped gap (7) of the paired support disks (4).

Description

technical field [0001] The invention relates to a support disc for the bearing structure of the shank of an open-end spinning rotor. The support disk has a disk-shaped base body and a lining applied to the outer circumference of the base body. The radially outer surface of the lining provides the running surface for the shank of the open-end spinning rotor, wherein the running surface is formed by two bearing surfaces spaced apart from one another in the axial direction of the support disc, each bearing surface having a bearing width, and groove-shaped recesses are formed between the bearing surfaces. Background technique [0002] Support discs for supporting open-end spinning rotors are already known in various designs in the prior art. Due to the very high rotational speeds of the spinning rotor, the support discs, in particular their working linings, are exposed to considerable stresses, which lead to high wear of the working linings. As a result, inhomogeneous running...
