Problems solved by technology

[0007] Bearing clearances often have to be designed larger than theoretically necessary, for example to be able to compensate for manufacturing tolerances or deformations caused by loads or thermal expansion, so that especially in these cases such hydrostatic sliding bearing assemblies are problematic in terms of energy efficiency

Embodiment Construction

[0064] figure 1 An embodiment is shown in which the plain bearing assembly is formed by a lower bearing element 1 and an upper bearing element 2 . Arranged in the lower bearing element is a recess 3 which forms a bearing chamber which is open in the direction of the opposite bearing element 2 . Such a bearing chamber 3 is filled with a preferably liquid fluid which is acted upon with hydrostatic pressure via an external pressure supply (shown here as a pump). For this purpose, a corresponding fluid delivery into the recess 3 takes place by the pressure supply. This embodiment of the pressure supply device is also suitable for the other embodiments shown below, although they are not shown here.

[0065] Between the two bearing elements 1 , 2 there is a bearing gap 4 which is substantially filled with the fluid of the bearing chamber 3 .

[0066] The two bearing elements 1 , 2 are separated from one another by the hydrostatic pressure action, so that there is no solid-body co...

Abstract

Hydrostatic plain bearing arrangement comprising a first, in particular lower bearing element (1) and a second, in particular upper bearing element (2), wherein at least one recess (3) is arranged inat least one of the bearing elements (1), in particular in the first bearing element (1), which recess (3) is open in the direction of the other bearing element (2) which preferably lies opposite, andwhich recess (3) forms at least one bearing pocket (3) which is filled with a fluid (FL1) which can be pressurized / is pressurized, wherein the at least one bearing pocket (3) is surrounded by at least one annular or frame-shaped sealing arrangement (5, 7 / 8, 6 / FL2). The invention also relates to a plain bearing arrangement of this type, in which the fluid (FL1) in the at least one bearing pocket (3) has the rheological behaviour of a Bingham body.

Description

technical field [0001] The invention relates to a hydrostatic sliding bearing assembly comprising a first bearing element, in particular a lower bearing element, and a second bearing element, in particular an upper bearing element, wherein in at least one of the bearing elements, in particular in the first Arranged in the bearing element is at least one recess which is open in the direction of the other, preferably opposite, bearing element and which forms at least one bearing chamber which is filled with a pressure-loadable fluid. Background technique [0002] During pressurization, the sliding bearing surface of the bearing element is at least partially, preferably completely, shielded from the force acting on the bearing element. As a result, the friction between opposing sliding bearing surfaces can be reduced. [0003] The pressure application can be achieved, for example, by means of a pump which pumps a fluid into the recesses through channels in the bearing element ...
