Abstract
Abstract A bearing assembly comprises a housing, a bearing and a shaft. Reaction to a radial load includes substantial components to each side of the radial load line and opposing each other. These components laterally stabilize the bearing. These reaction components arise because the assembly has an arcuate less stiff portion in line with the radial load line.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
A bearing assembly comprising a housing having a bore, a bearing which is disposed in the bore and a shaft which is supported by the bearing for rotation with respect to the housing, wherein the bearing is supported substantially over its complete circumference by at least two portions of differing stiffness, which are circumferentially adjacent to each other and extend longitudinally of the bearing, each less stiff portion being arcuate and centered on the bearing axis, such that the reaction to a load acting along a radius of the bearing includes substantial components to each side of that radius which are opposed to each other.
Claim 2
Dependent Claim
105 words
A bearing assembly comprising a housing having a bore, a bearing which is disposed in the bore and a shaft which is supported by the bearing for rotation with respect to the housing, wherein the bearing is supported substantially over its complete circumference by at least two portions of differing stiffness, which are circumferentially adjacent to each other and extend longitudinally of the bearing, each less stiff portion being arcuate and centered on the bearing axis, such that the reaction to a load acting along a radius of the bearing includes substantial components to each side of that radius which are opposed to each other.
Claim 3
Dependent Claim
27 words
An assembly as claimed in claim 1, wherein the housing includes the portion which is less stiff than adjacent portions and is in line with that radius.
Claim 4
Dependent Claim
24 words
An assembly as claimed in claim 2, wherein the housing includes a sleeve, the less stiff portion being an integral part of the sleeve.
Claim 5
Dependent Claim
18 words
An assembly as claimed in claim 3, wherein means fix the position of the sleeve in the housing.
Claim 6
Dependent Claim
24 words
An assembly as claimed in claim 1, wherein the less stiff portion is provided by a recess which is radially spaced from the bearing.
Claim 7
Dependent Claim
17 words
An assembly as claimed in claim 5, wherein the recess is positioned radially outside of the bearing.
Claim 8
Dependent Claim
25 words
An assembly as claimed in claim 1, wherein the radial thickness of the less stiff portion is 0.15 x the sectional height of the bearing.
Claim 9
Dependent Claim
25 words
An assembly as claimed in claim 1, wherein the less stiff portion subtends laterally an angle of 50° from the longitudinal axis of the bearing.
Claim 10
Dependent Claim
23 words
An assembly as claimed in claim 1, wherein the less stiff portion extends longitudinally of the bearing and is unsupported at its ends.
