Abstract
Abstract The invention relates to a three point ball bearing arrangement which facilitates rotation in a desired direction and at the same time restricting unwanted relative lateral movement between the balls and its associated ball race. The arrangement provides for two annular surfaces enclosing the balls and on one surface of which one bearing point is provided and on the other surface of which two bearing points are provided. A tangent to the bearing point of the first annular surface intersects a straight line joining the two bearing points of the second annular surface at the axis of rotation of the arrangement.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
In a three-point annular ball bearing arrangement comprising a first bearing ring having a first inclined annular ball bearing surface with a tangent at its bearing point oblique to and intersecting the axis of rotation of the ball bearing arrangement, a second bearing ring having a second annular ball bearing surface, and a third bearing ring having a third radial annular ball bearing surface and connected for common rotation with the second bearing ring, the third bearing ring being axially moveable and the third radial annular bearing surface having radial tangent at its bearing point and being axially biased toward the first inclined annular bearing surface, the improvement wherein the third bearing ring is a spring washer which itself, axially biases the third radial annular bearing surface toward the first inclined annular bearing surface and wherein a line connecting the bearing points on the second and third annular bearing surfaces intersects the axis of rotation at the intersection of the bearing point tangent of the first annular bearing surface.
Claim 2
Dependent Claim
169 words
In a three-point annular ball bearing arrangement comprising a first bearing ring having a first inclined annular ball bearing surface with a tangent at its bearing point oblique to and intersecting the axis of rotation of the ball bearing arrangement, a second bearing ring having a second annular ball bearing surface, and a third bearing ring having a third radial annular ball bearing surface and connected for common rotation with the second bearing ring, the third bearing ring being axially moveable and the third radial annular bearing surface having radial tangent at its bearing point and being axially biased toward the first inclined annular bearing surface, the improvement wherein the third bearing ring is a spring washer which itself, axially biases the third radial annular bearing surface toward the first inclined annular bearing surface and wherein a line connecting the bearing points on the second and third annular bearing surfaces intersects the axis of rotation at the intersection of the bearing point tangent of the first annular bearing surface.
Claim 3
Dependent Claim
47 words
An arrangement according to claim 1, in which at least one ball-bearing is arranged for operation in one direction , each such ball-bearing having an associated spring washer assembled so as to be free from play relative to a further ball-bearing operative in the axially opposite direction.
Claim 4
Dependent Claim
55 words
An arrangement according to claim 2 in combination with a housing, a shaft mounted for rotation therein and a seal between the housing and shaft, said seal comprising a collar fixed in the housing and sealingly engaging the periphery of the shaft, the collar being formed of a material of limited flexibility such as polytetrafluoroethylene.
Claim 5
Dependent Claim
21 words
A three-point annular ball bearing arrangement according to claim 1 wherein the second annular bearing surface is a cylindrical bearing surface.
Claim 6
Dependent Claim
21 words
A three-point annular ball bearing arrangement according to claim 1 or 4 further comprising a substantially cylindrical ball bearing guide surface.
