Abstract
Abstract A spherical bearing comprises an outer ring and an inner ring located inside the outer ring to be slidable, the outer ring is prepared by casting molten metal around a resin-made sheet to be coated on the inner ring. A liner disposed between the inner and outer ring comprises a liner body and a metallic mesh member embedded in the liner body, and the molten metal is filled in meshes in the mesh member so as to partially bite the inner peripheral portion of the outer ring to achieve the firm engagement of the liner with the outer ring.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
76 words
A spherical bearing comprising: an outer ring; an inner ring located inside said outer ring to be slidable; and a liner disposed between said outer ring and said inner ring, said liner comprising a liner body made of resin and a metallic mesh member embedded in said liner body, said metallic mesh member partially biting an inner peripheral portion of said outer ring so as to achieve firm engagement of said liner with said outer ring.
Claim 2
Dependent Claim
76 words
A spherical bearing comprising: an outer ring; an inner ring located inside said outer ring to be slidable; and a liner disposed between said outer ring and said inner ring, said liner comprising a liner body made of resin and a metallic mesh member embedded in said liner body, said metallic mesh member partially biting an inner peripheral portion of said outer ring so as to achieve firm engagement of said liner with said outer ring.
Claim 3
Dependent Claim
46 words
The spherical bearing according to claim 1 wherein said liner body is made of resin having a low coefficient of friction and excelling in frictional resistance and in heat resistance such as fluoride-based resin and said metallic mesh member is made of bronze or stainless steel.
Claim 4
Dependent Claim
50 words
The spherical bearing according to claim 1 wherein said metallic mesh member is embedded into said liner body in a manner such that said liner body has a thin portion on a side contacting to the inner ring and a thick portion on a side joining to the outer ring.
