Abstract

A bearing arrangement ( 28 ) having at least one radial air bearing ( 1 ) and/or having an axial air bearing ( 15 ′). The radial air bearing ( 1 ) has an inner annular bearing plate ( 7 ) and a spring plate ( 10 ) which surrounds the bearing plate ( 7 ) at the outside. The bearing plate and spring plate being formed as a single-piece component.

First claim

The invention claimed is:

1. A bearing arrangement ( 28 ) having
at least one radial air bearing ring ( 1 ); and
optionally additionally an axial air bearing ( 15 ′),
wherein the radial air bearing ring ( 1 ) has an inner annular bearing plate ( 7 ) and an outer spring plate ( 10 ) along one side of the bearing plate ( 7 ), wherein the bearing plate ( 7 ) and spring plate ( 10 ) are together formed from a single elongate Plate strip with the bearing plate ( 7 ) connected via a bent connecting portion ( 9 ) to the spring plate ( 10 ), such that said bearing plate and spring plate form a single-piece component.

2. The bearing arrangement as claimed in claim 1 , wherein the single-piece component constructed from the bearing plate ( 7 ) and the spring plate ( 10 ) has at least one retaining lug ( 11 , 12 ).

3. The bearing arrangement as claimed in claim 1 , wherein the spring plate ( 10 ) is of corrugated form.

4. The bearing arrangement as claimed in claim 1 , wherein the at least two plate portions ( 2 , 3 , 4 ) are assembled to form a bearing ring.

5. The bearing arrangement as claimed in claim 1 , wherein an intermediate layer ( 15 ) is provided between the bearing plate ( 7 ) and the spring plate ( 10 ).

6. The bearing arrangement as claimed in claim 1 , wherein the axial air bearing ( 15 ′) has an annular bearing plate ( 16 ) and an annular spring arrangement ( 17 , 18 , 19 , 19 ′, 25 ) on which is arranged a cover plate ( 38 ) which is provided with a device ( 42 ) for building up air pressure between the bearing plate ( 16 ) and the spring arrangement ( 17 , 18 , 19 , 19 ′, 25 ).

7. The bearing arrangement as claimed in claim 1 , wherein the axial air bearing has an annular carrier plate ( 43 ) on which is arranged a curved ramp ( 50 ) for building up air pressure.

8. The radial air bearing as claimed in claim 1 , wherein the single-piece component constructed from the bearing plate ( 7 ) and the spring plate ( 10 ) has at least one retaining lug ( 11 , 12 ).

9. The bearing arrangement as claimed in claim 1 , wherein at least three plate portions ( 2 , 3 , 4 ) are assembled to form a bearing ring.
