Abstract
Abstract A method of making a self aligning spherical bearing from three parts, a spherical inner race and two outer race components, the method comprising holding one outer race component, positioning and holding the spherical inner race therein, positioning the other outer race component in alignment therewith and friction welding the two outer race components together until the meeting faces of the two outer race components are in contact to provide a controlled clearance between the inner and outer races.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
A method of making a self aligning spherical bearing comprising the steps of placing an outer bearing race component in a holding fixture, placing an inner spherical bearing race in a holding fixture adjacent said outer bearing race component, placing a second outer bearing race component in a rotatable bearing fixture in contact with said outer bearing race component, rotating said second outer bearing race component relative to said first bearing race component while applying axial pressure thereto for fusion welding, directing the flash weld material into a space in at least one of said outer bearing race components, stopping rotation of said second outer bearing race component at a predetermined axial location, applying axial pressure on said second outer bearing race component until stop faces on said outer bearing race components are in contact and removing the completed bearing from said holding fixture.
Claim 2
Independent Claim
144 words
A method of making a self aligning spherical bearing comprising the steps of placing an outer bearing race component in a holding fixture, placing an inner spherical bearing race in a holding fixture adjacent said outer bearing race component, placing a second outer bearing race component in a rotatable bearing fixture in contact with said outer bearing race component, rotating said second outer bearing race component relative to said first bearing race component while applying axial pressure thereto for fusion welding, directing the flash weld material into a space in at least one of said outer bearing race components, stopping rotation of said second outer bearing race component at a predetermined axial location, applying axial pressure on said second outer bearing race component until stop faces on said outer bearing race components are in contact and removing the completed bearing from said holding fixture.
Claim 3
Dependent Claim
29 words
The method defined in claim 1 in which the flash weld material is directed into a plurality of spaces in at least one of said outer bearing race components.
Claim 4
Dependent Claim
26 words
The method defined in claim 1 in which the flash material is directed into a plurality of spaces in each of said outer bearing race components.
Claim 5
Dependent Claim
29 words
The method defined in claim 1 in which said outer race components each have a plurality of stop faces which are brought into contact by said axial pressure application.
