Problems solved by technology

In the case of this material pair, the usual operation of plain bearings in the mixed friction area leads to premature failure of the plain bearing and thus premature failure of the plain bearing due to high surface wear on the counterpart

Embodiment Construction

[0022] exist figure 1 As can be seen in , the slide bearing is surrounded on the outside by a housing 1 which acts as a bearing shell. The bearing outer ring 2 surrounded by the housing 1 is held by the housing 1 . The bearing inner ring 4 carrying the hard material layer 3 rests in the bearing outer ring 2 . The bearing inner ring 4 itself is shrink-fitted onto the shaft 5 . Finally, a bearing gap 6 is visible between the hard material layer 3 and the bearing outer ring 2 . A lubricant (not shown in the drawing) is introduced into the bearing gap 6 and forms a lubricating film during operation.

[0023] Thus, in the exemplary embodiment, the shaft 5 with its bearing inner ring 4 forms the rotational friction part of the slide bearing. On the contrary, the housing 1 forms with its bearing outer ring 2 the counterpart of the sliding bearing. In this exemplary embodiment, the bearing inner ring 4 carries on the shaft 5 a hard material layer 3 which can consist of the materi...

Abstract

The invention relates to a slide bearing comprising a rotating friction partner, a counterpart and a lubrication film between the friction partner and the counterpart, wherein the friction partner or the counterpart is coated with a hard material.

Description

technical field [0001] The invention relates to a sliding bearing, especially a hydrodynamic sliding bearing. Plain bearings of this type generally have a rotating friction part, a counterpart supporting the rotating friction part, and a lubricant film between the friction part and the counter part. Background technique [0002] At high loads and at low relative speeds, the friction part and counter part of the plain bearing move in a so-called mixed friction state. This means that the rotating friction part is not completely supported by the intermediate lubricating film, but surface contact occurs between the rotating friction part and the counter part. This surface contact causes wear both on the friction part and on the counter part. [0003] In general, the friction part (ie usually the shaft) with hoop load should have a higher microhardness than the counter part. Due to this configuration, the surface profile of the counter part matches the profile of the friction ...
