Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
A method of manufacturing a self-aligning spherical bearing comprising the steps of preforming an outer member having a concave spherical inner surface, preforming an inner member having a convex spherical outer surface generally complementary to the said concave spherical inner surface, said inner member being split to form a departure therethrough, said departure being tangential to a central hole provided in said inner member, reducing the outer diameter of said inner member, said reduction in said outer diameter being accommodated by said split in said inner member, inserting said inner member within said outer member, releasing said inner member such that it substantially regains its original dimensions whereby it is operationally supported within said outer member at said outer member's concave spherical inner surface.
Claim 2
Independent Claim
124 words
A method of manufacturing a self-aligning spherical bearing comprising the steps of preforming an outer member having a concave spherical inner surface, preforming an inner member having a convex spherical outer surface generally complementary to the said concave spherical inner surface, said inner member being split to form a departure therethrough, said departure being tangential to a central hole provided in said inner member, reducing the outer diameter of said inner member, said reduction in said outer diameter being accommodated by said split in said inner member, inserting said inner member within said outer member, releasing said inner member such that it substantially regains its original dimensions whereby it is operationally supported within said outer member at said outer member's concave spherical inner surface.
Claim 3
Dependent Claim
28 words
A method of manufacturing a self-aligning bearing in accordance with claim 1 wherein the deforming of said inner member includes placing said inner member within a tapered die.
Claim 4
Dependent Claim
36 words
A method of manufacturing a self-aligning bearing in accordance with claim 1 wherein said method includes the additional step of inserting a tapered collar within a centrally disposed complementally formed tapered hole through said inner member.
Claim 5
Dependent Claim
34 words
A method of manufacturing a self-aligning bearing in accordance with claim 1 wherein said method includes the additional step of coating the lateral faces as defined by said departure with a self-lubricated plastic material.
Claim 6
Dependent Claim
19 words
The self-aligning bearing manufacturing method of claim 1 wherein said inner member is provided with a central hole therethrough.
Claim 7
Dependent Claim
25 words
The self-aligning bearing manufacturing method of claim 5 wherein said central hole in said inner member is tapered to accept a complementary tapered collar therein.
Claim 8
Dependent Claim
23 words
The self-aligning bearing manufacturing method of claim 6 wherein said collar is provided with a central bore to accept an attaching means therethrough.
Claim 9
Dependent Claim
36 words
The self-aligning bearing manufacturing method of claim 7 wherein said attaching means includes a bolt, a nut threadably attached to the bolt, said bolt and said nut operationally attaching said inner member to a machine element.
