Abstract

A bearing support includes at least one sliding bearing defined by the bearing support and/or at least one rolling-element bearing having an outer raceway defined by the bearing support. The bearing support is formed from a fiber-plastic composite and includes an integrally formed sliding surface of the sliding bearing and/or an integrally formed raceway for rolling elements of the rolling-element bearing, and the fiber-plastic composite includes a matrix into which spatially oriented sliding fibers, for example, PTFE fibers, are embedded in a region of the sliding surface of the sliding bearing and/or a region of the raceway of the rolling-element bearing.

First claim

The invention claimed is:

1. A bearing support comprising:
the bearing support defining an outer raceway for a rolling-element bearing wherein the outer raceway is integrally formed with the bearing support and is configured for rolling elements of the rolling-element bearing, wherein the bearing support is formed from a fiber-plastic composite, wherein the fiber-plastic composite comprises a matrix with a plurality of fibers therein and into which additional spatially oriented sliding fibers are embedded in the region of the outer raceway, the additional spatially oriented sliding fibers being configured to dissipate forces away from the region in a targeted manner, wherein the additional spatially oriented sliding fibers are a tube shaped mesh; and
wherein the outer raceway is formed by a bearing ring disposed on the bearing support.

2. The bearing support according to claim 1 , wherein the additional spatially oriented sliding fibers comprise woven fabric.

3. The bearing support according to claim 2 , wherein the reinforcing fibers are glass fibers and/or carbon fibers and/or ceramic fibers and/or aramid fibers and/or boron fibers and/or basalt fibers and/or steel fibers and/or natural fibers and/or polyhexamethylene adipic acid amide fibers.

4. The bearing support according to claim 2 , wherein the additional spatially oriented sliding fibers comprise a prefabricated or semi-finished structure, wherein the matrix comprises a duroplast and/or an elastomer and/or a thermoplastic, wherein the plurality of fibers comprise PTFE fibers.

5. The bearing support according to claim 1 , wherein the additional spatially oriented sliding fibers comprise a prefabricated semi-finished structure.

6. The bearing support according to claim 1 , wherein the matrix comprises a duroplast and/or an elastomer and/or a thermoplastic.

7. The bearing support according to claim 1 , wherein the sliding fibers comprise PTFE fibers.

8. The bearing support according to claim 1 , wherein the fiber-plastic composite comprises a carbon-fiber-reinforced fiber-plastic composite, and wherein the carbon fibers are embedded in the matrix, the matrix comprising an epoxy resin.
