Abstract
Abstract A spherical bearing assembly has a metal inner race member and an outer race member. The inner surface of the outer race member is a concave spherical surface and the outer surface of the inner member is a complementary convex spherical surface. The outer member includes an annular recess the base of which is threaded. The recess is adapted to threadably receive a first yieldable plastic annular ring whose outer surface is threaded with threads complementary to the threads on the base of the recess. A second formable and yieldable annular ring is also received in the recess in a side-by-side relationship with the first annular ring. The inner surface of the first and second annular rings provide approximately one-half of the concave spherical surface of the outer race member. The first annular ring operationally captures the second annular ring and the inner race member within the outer race member.

Claim 1
Independent Claim
161 words
A spherical bearing assembly having a metal inner race member and an outer race member, the inner surface of the outer race member being a concave spherical surface, the outer surface of the inner member being a complementary convex spherical surface, the outer member including an annular recess the base of which is threaded, a first yieldable plastic annular ring having an outer surface threaded with threads complementary to the threads on the base of said recess, said ring threadably received in said recess, a second annular ring also received in said recess in a side-by-side relationship to said first annular ring, the second annular ring being made of a formable and yieldable plastic material, and the first and second annular rings providing a substantial portion which is more than half of the concave spherical surface of said outer race member, said first annular ring operationally capturing said second annular ring and said inner race member within said outer race member.
Claim 2
Dependent Claim
161 words
A spherical bearing assembly having a metal inner race member and an outer race member, the inner surface of the outer race member being a concave spherical surface, the outer surface of the inner member being a complementary convex spherical surface, the outer member including an annular recess the base of which is threaded, a first yieldable plastic annular ring having an outer surface threaded with threads complementary to the threads on the base of said recess, said ring threadably received in said recess, a second annular ring also received in said recess in a side-by-side relationship to said first annular ring, the second annular ring being made of a formable and yieldable plastic material, and the first and second annular rings providing a substantial portion which is more than half of the concave spherical surface of said outer race member, said first annular ring operationally capturing said second annular ring and said inner race member within said outer race member.
Claim 3
Dependent Claim
35 words
A spherical bearing assembly in accordance with claim 1 wherein the inner surface of said second annular ring is smooth and the portion of said recess which receives said second annular ring is also smooth.
Claim 4
Dependent Claim
23 words
A spherical bearing assembly in accordance with claim 1 wherein said second annular ring applies a preloading force to said inner race member.
Claim 5
Dependent Claim
29 words
A spherical bearing assembly in accordance with claim 3 wherein said preloading force is effected by threading said first annular ring in intimate contact with said second annular ring.
Claim 6
Dependent Claim
22 words
A spherical bearing assembly in accordance with claim 3 wherein said preloading force is effected by providing an oversized second annular ring.
Claim 7
Dependent Claim
24 words
