Abstract
Abstract A spherical bearing assembly having an 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 inner member including a spool member having first and second threaded portions disposed on its outer surface at each end thereof and a smooth truncated conical section interposed therebetween, at least three spherical segments, each segment having a conical portion on its inner surface complementary to the truncated conical section on the outer surface of the spool member, first and second internally threaded annular rings adapted to be threaded on each end of the spool member in meshing relationship with the first and second threaded portions on each end of the spool member respectively, the segments disposed on and interlocked with the spool member by the annular rings.

A spherical bearing assembly having an 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 inner member including a spool member having first and second threaded portions disposed on its outer surface at each end thereof and a smooth truncated conical section interposed therebetween, at least three spherical segments, each segment having a conical portion on its inner surface complementary to the truncated conical section on the outer surface of the spool member, the conical portions of the segments directly contacting the conical outer surface of the spool member, first and second internally threaded annular rings adapted to be threaded on each end of the spool member in meshing relationship with the first and second threaded portions on each end of the spool member respectively, the segments disposed on and interlocked with the spool member by the annular rings, whereby the conical section, the conical portions, and the rings are concurrently used to adjust spaces between adjacent segments, between the inner and outer members, and between the segments and the spool.
Claim 2
Dependent Claim
197 words
A spherical bearing assembly having an 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 inner member including a spool member having first and second threaded portions disposed on its outer surface at each end thereof and a smooth truncated conical section interposed therebetween, at least three spherical segments, each segment having a conical portion on its inner surface complementary to the truncated conical section on the outer surface of the spool member, the conical portions of the segments directly contacting the conical outer surface of the spool member, first and second internally threaded annular rings adapted to be threaded on each end of the spool member in meshing relationship with the first and second threaded portions on each end of the spool member respectively, the segments disposed on and interlocked with the spool member by the annular rings, whereby the conical section, the conical portions, and the rings are concurrently used to adjust spaces between adjacent segments, between the inner and outer members, and between the segments and the spool.
Claim 3
Dependent Claim
98 words
A spherical bearing assembly in accordance with claim 1 further comprising an adjustable clearance between the inner race member and the outer race member at the inner surface of the outer race member and the outer surface of the inner member which adjustable clearance adjusted by the rotation of said first annular ring in clockwise or counterclockwise direction, said second annular ring maintaining the desired clearance by abutting the lateral face provided on the sides of said spherical segments thereby relatively axially sliding the spool and spherical segments and moving the spherical segments with respect to each other.
Claim 4
Dependent Claim
114 words
A spherical bearing assembly in accordance with claim 1 in which said convex outer surface of said spherical segments define a first bearing surface, said concave inner surface of said outer race member defining a second bearing surface in bearing contact with said first bearing surface, said outer conical surface of said spool member defining a third bearing surface and said inner conical surface of said spherical segments defining a fourth bearing surface in bearing contact with said third bearing surface, said first and second bearing surfaces comprising the primary operational bearing surface of said spherical bearing assembly, said third and fourth bearing surface providing a secondary bearing surface for said spherical bearing assembly.
