Problems solved by technology

[0012] So-called high-performance plain bearings with a sliding layer produced by the sputtering method are suitable for these purposes, since the sputtered sliding layer usually has a very high hardness and thus an increased load capacity, but on the other hand these bearings are relatively expensive

Embodiment Construction

[0037] figure 1 A side view of a plain bearing half shell in a multilayer plain bearing 1 (multilayer plain bearing) is shown. Shown is an embodiment of this sliding bearing 1 , ie it is a two-layer bearing comprising a metal support layer 2 on which an additional metal layer is formed directly, forming the sliding layer 3 . The sliding layer 3 is a layer that slides with respect to the supporting member.

[0038] Plain bearings 1 of this basic construction, for example for use in motor vehicles or in large diesel engines, such as marine diesel engines, are known from the prior art and require no further implementation. It should be noted that further layers can also be provided, for example a bearing metal layer 4 between the sliding layer 3 and the support layer 2, such as figure 1 In the three-layer manner shown by the dotted line, the bearing metal layer 4 can be directly arranged on the support layer 2 , and the sliding layer 3 can be directly arranged on the bearing me...

Abstract

The invention discloses a method for manufacturing a sliding bearing (1). The method includes the following steps that a metal supporting layer (2) is provided, and an additional metal layer made of a spraying material is directly sprayed on the metal supporting layer (2) or sprayed on the metal supporting layer (2) through at least one metal interlayer, wherein the additional metal layer is made of a tin base alloy provided with a tin-rich substrate in which hard particles (10) and/or soft particles (11) are added, the hard particles (10) are harder than the substrate and/or the soft particles (11) are softer than the substrate; and the spraying material (5) is adopted, under the condition that the spraying material (5) contains the hard particles (10), the additional metal layer with the hard particles (10) is formed, and/or under the condition that the spraying material (5) contains the soft particles (11), the additional metal layer with the soft particles (11) is formed, wherein the hard particles (10) and/or the soft particles (11) maintain a solid form in the spraying process.

Description

technical field [0001] The invention relates to a method for producing a plain bearing, comprising the steps of providing a metallic support layer and an additional metallic layer of sprayed material sprayed directly on the support layer or via at least one metallic intermediate layer, wherein , the additional metal layer is made of a tin-based alloy with a tin-rich substrate with added hard particles and / or soft particles, wherein the hard particles are harder than the substrate, and / or wherein the soft particles are softer than the substrate. Background technique [0002] Tin-based alloys for the sliding layer of multilayer plain bearings are known from the prior art. [0003] The plain bearing shell described in the examples of DE8206353U1 consists of a steel lining, a support layer, optionally one or more adhesive and / or insulating layers, and an electroplated sliding layer of a tin-based white metal bearing alloy , the tin substrate has at most (weight percent) 2% Cu, ...
