Furthermore, it is known to use low friction bearings as so-called Form hydrostatic bearings, with a liquid, in various cases also a gas, as a supporting layer between Bearing journal and bearing housing absorbs the full load and the;

Otherwise there would be friction between the moving parts in the inner one Friction of the fluid converts.

Based on the basically known structure of a plain bearing with self-adjustment through ball-bearing mounting of the bearing pin bearing body in the bearing housing and the known hydrostatic bearing between the bearing journal and bearing body is used to take advantage of a plain bearing even for high loads, like ζ. B. in the converter storage to take advantage of, proposed according to the invention that the bearing body hydrostatically | is stored. - "-;

The embodiment according to the invention thus ensures in a simple I

rather, by making advantageous use of the experience known from the hydrostatic bearing between bearing journal and bearing body, that the bearing body can only adjust to any deformation of the shaft or axle, which is subject to high and / or swelling loads, against the extremely low fluid friction. In the case of very high and constantly changing loads, such as B. occur in the converter storage, edge pressures are largely avoided, but the surface pressure can be kept within permissible limits by the surface contact.

The hydrostatic bearing of the spherically movable bearing body can be combined with any conventional bearing or lubrication of the bearing journal. However, it proves to be particularly advantageous if, in a further embodiment of the inventive concept _3, the bearing journal and the bearing body are mounted hydrostatically otherwise high starting friction can be significantly reduced.

In order to ensure that the bearing pin wirdj supported with certainty always floating in the bat body to a further feature of the invention is according ;, the impact surface in the bearing housing is smaller than the impact surface in the bearing body _S so that the bearing force between the shaft and bearing body is not smaller than that between the bearing body and Bearing housing can be.

In normal cases it is considered sufficient that the The difference in area is about 5%.

The drawing shows an embodiment of the invention as an example shown schematically.

The illustration shows the cross-section of a bearing according to the invention, in which, for example, both the bearing journal and the bearing body are hydro- ₍ statically supported,

The bearing housing 1 encloses the ball-movable bearing body 2 in a manner known per se, which in turn carries the bearing journal 3.

The pressure medium enters the impingement surface through the opening 4 im'lagergehäuses 1 and further through the bore 6 into the impingement surface 7-in the bearing body 2., Then runs through the bores 8 and the outlets 9 back again and thus effects the hydrostatic storage of both the bearing journal 3 and the bearing body 2.
