Abstract
Abstract A method of manufacturing a spherical bearing rod end having an outer race member, an intermediate member of yieldable material within and supported by said outer race member and an inner race operationally supported by said intermediate member comprising preforming a rod end blank having a ball-like section at one end thereof, flattening the spherical section to form two enlarged faces, each face having an inwardly disposed annular dished portion whereby the material flows uniformly to the outer periphery of the faces to form a uniformly cold formed annular area, removing the inwardly disposed annular dished portion to form a bore through said faces thereby leaving said uniformly cold formed annular area to serve as the outer member, inserting in said bore said intermediate member and said inner race member, interlocking with mechanical interlocking means said intermediate member and inner race member within said bore to effect the bearing support of said inner race member within said intermediate member.

Claim 3
Dependent Claim
35 words
A method of manufacturing a spherical rod end bearing in accordance with claim 1 wherein the step of flatteniNg includes restraining and controlling the outward radial flow of material as it forms said two faces.
Claim 4
Dependent Claim
22 words
A method of manufacturing a spherical bearing rod end in accordance with claim 2 wherein the restraining is effected by restraining dies.
Claim 5
Dependent Claim
44 words
A method of manufacturing a spherical bearing rod end in accordance with claim 2 including forming a dimple on each said face which positionally locates said rod end blank thereby assuring that said cold formed annular area is formed in a substantially circular configuration.
Claim 6
Dependent Claim
25 words
A method of manufacturing a spherical bearing rod end in accordance with claim 1 wherein the inwardly disposed annular dished portions are removed by machining.
Claim 7
Dependent Claim
56 words
A method of manufacturing a spherical bearing rod end in accordance with claim 1 wherein the interlocking means includes at least one annular rib on the inner surface of said bore and at least one complementary annular groove on the outer surface of said intermediate member, said annular rib adapted to fit within said annular groove.
Claim 8
Dependent Claim
25 words
A method of manufacturing a spherical bearing rod end in accordance with claim 1 wherein said intermediate member is made of a yieldable plastic material.
Claim 9
Independent Claim
163 words
A method of manufacturing a blank for a spherical bearing rod end having an outer race member, an intermediate member of yieldable material within and supported by said outer race member and an inner race operationally supported by said intermediate member comprising preforming a rod end blank having a spherical section at one end thereof, flattening the spherical section to form two enlarged faces, each face having an inwardly disposed annular dished portion whereby the material flows uniformly to the outer periphery of the faces to form a uniformly cold formed annular area removing the inwardly disposed annular dished portion to form a bore through said faces thereby leaving said uniformly cold formed annular area to serve as the outer race member, inserting in said bore said intermediate member and said inner race member, interlocking with mechanical interlocking means said intermediate member and inner race member within said bore to effect the bearing support of said inner race member within said intermediate member.
