動作中に支持円板を介して軸１に作用する軸線方向推力
についても、これ以上詳細に説明するには及ばない。According to FIG. 1, the shaft 1 of the oven-end spinning rotor, in particular with support disc bearings, is arranged in pairs on the shafts 2 and 3 and between the wedges of freely rotatable support discs 4 and 5. It is supported within the framework. The support discs 4 and 5 have an elastic coating on one circumferential surface, the covering being made of plastic, the relief being made of polyurethane or other suitable material, and for the shaft 1 having a rotating surface 4.0. .50 is formed. The tangential belt 6 drives the shaft l of a predetermined thickness in the rotational directions 40 and 50 ('=J).Such bearings are generally known and therefore in particular the The axial thrusts acting on the shaft 1 via the support disc during the rotational movement also do not need to be explained in further detail.

欠きは、椋々の方法で構成かつ配置できる。As already explained at the outset, in this bearing the plastic sheathing is subjected to high loads due to the shaft l, which causes wear and damage in the directions of rotation 4o and 50. In order to prevent this and extend the life of the rotating surfaces 4o and 50, the nine rotating surfaces are interrupted by notches. These recesses can then be designed and arranged in a customary manner.

。However, a groove-shaped recess is advantageous, which extends in the direction of rotation of the supporting discs 4 and 5 and is arranged centrally between the rotational surfaces 40 and 50 (FIG. 2). The shapes of such endless grooves may be different. As shown in FIG. 2 for configurations a to d, +ij! 7 is an example of a wedge shape, a square,
Can be semicircular or trapezoidal. Configuration e in Figure 2
In this case, next to the M7 placed on the medium heat, there are two other M7's extending parallel to the central groove.
回転面４０または５００周面は、全体で３つの切欠きに

ることにより、軸１は一撃なくころがる。During operation, the shaft 1 rests on the rotating surfaces 40 and 50 on both sides of the groove 7, 7', the thrust of the shaft 1 in the elastic wave υ can also become a contact surface if the forces are large. Tangents of some axes are free to bridge the grooves. By placing the shaft 1 on both sides of the notch, the shaft 1 rolls without a single hit.

の回転面は十分大きいからである。FIG. 3 shows another possibility of configuring the cutout interrupting the plane of rotation. In configuration a, gqo extends helically around the surface of one revolution. The arrangement shows a rotational surface interrupted by a plurality of grooves 71 arranged at an angle to the direction of rotation of the support disk and spaced from one another. The angle and width of the reins 71 are chosen such that the shaft 1 does not fit into the grooves, but bridges the grooves. If the grooves 71 extend to the edge of the rotating surface, like the grooves 70 in the configuration aK of FIG. 3, conventional knowledge does not prevent a bombardment-free rotation of the spinning rotor. This is because the groove protrudes from the edge and the rotation surface for the shaft is sufficiently large.

In configuration d of 1, the cutout is formed by holes 9 arranged next to each other in the center of the plane of revolution. Configuration eK

るように考慮する。This airflow provides cooling of the elastic coating and thereby reduces wear caused by excessive heat. In order to improve heat dissipation and thus prevent heat build-up that could lead to damage to the building construction,
The notch must have suitable dimensions. For example, in an experiment with a cover of 6 dragons' thickness, approximately the thickness of the cover.
A notch with a depth of up to s was found to be particularly effective. Similarly, the width of the cutout must be taken into account to ensure effective ventilation and therefore heat dissipation.
