Cl.2 B63H 23/34 Inventor: Patent holder: Howaldtswerke-Deutsche Werft Aktiengeseilschaft Hamburg und Kiel, Kiel (Federal Republic of Germany) Single-disc thrust bearing for a ship's shaft The invention relates to a single-disc thrust bearing for a ship's shaft, with a single or multi-part bearing body having spherically shaped outer surfaces. Single-disc thrust bearings for a ship's shaft, even with the possibility of axial displacement of the bearing, are known as such. It is also known to support the body of a single-disc thrust bearing with nearly spherical surfaces in order to increase the possibility of adjusting the thrust bearing and to compensate for assembly inaccuracies. Finally, it is also known to achieve, with the possibility of adjusting the bearing position by means of nearly spherical housing planes, the possibility of axial adjustment at the same time. However, all these known adjustment possibilities always require a special bearing design, which is in part expensive and heavy. The object of the invention is to create such a design of a single-plate thrust bearing that, as a standard version, can be used as desired with the least possible effort for all these types of adjustments. The solution according to the invention consists in the fact that the bearing housing has mounting flanges on at least two of its opposite outer walls. The thrust bearing is then used together with its bearing housing as a stationary bearing and is permanently mounted in its desired position by means of a mounting flange and screws. Thus, the single-disc thrust bearing according to the invention can be used to great effect both with and without mounting on surfaces close to spherical, as well as without the possibility of adjusting its position. The subject of the invention is explained in an example embodiment in the drawing, in which Fig. II shows a top view of a single-disc thrust bearing with a ship's wind, and Fig. 2 shows a longitudinal section according to line II-II in Fig. 1, assuming no outer bearing housing. The single- or multi-part bearing housing 1 has outer surfaces 2 about the shape towards the leaves. In the bearing housing 1, the ship's shaft 3 is guided by means of a support disc 4. The means for guiding the support disc are known per se and consist of pressure elements 5, which are guided on journals 6 (Fig. 2). For permanent fixing of the bearing housing 1, it is provided with mounting flanges 7, which have holes 8 for inserting screw elements into them. In order to be able to describe the bearing housing 1 without changes on planes that are almost spherical and to be able to compensate for mounting inaccuracies, an outer bearing housing 9 is provided with spherical inner surfaces 10, in which the bearing housing 1 is arranged and guided, so that when the outer bearing housing 9 is used, a bearing is automatically created. amazing. In the outer bearing cap 9, the bearing body 1 is not permanently mounted. On the mounting flanges 7, the outer bearing body 9 is permanently and immobilely mounted. P a t i e n t s e r m e n t s 1. Single-disc thrust bearings of the ship's shaft with one single- or multi-piece bearing body with spherical shapes external surfaces, characterized in that the bearing body (1) has mounting flanges (7) on at least two external walls lying opposite each other. 2. Single disc bearing according to claim. 1, characterized in that the bearing housing (1) is guided in one external housing (9) having spherical internal surfaces. FIG.1 F/G.1 W.Z.Graf.
