Abstract
Abstract A self-aligning bearing arrangement has a compressible packing (20) for forming a gas-tight seal between the outer housing (2) and a rotatable shaft (10). A bushing ring (22) supports the shaft (10) and accommodates any misalignment thereof by having an inner surface (26) of convex cross section. The bushing ring (22) is urged axially against the packing (20) by a drive plate (28) and urging means (30, 32).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
A self-aligning bearing for supporting a rotatable cylindrical shaft, comprising: a housing, disposed around the shaft; an annular packing, disposed between the shaft and the bearing, for forming a gas-tight seal therebetween; a bushing ring, having an external surface closely fitting within the housing, and an internal surface of convex cross section, the bushing ring being disposed axially outward of the annular packing; and means for urging the bushing ring axially inward against the packing.
Claim 2
Dependent Claim
75 words
A self-aligning bearing for supporting a rotatable cylindrical shaft, comprising: a housing, disposed around the shaft; an annular packing, disposed between the shaft and the bearing, for forming a gas-tight seal therebetween; a bushing ring, having an external surface closely fitting within the housing, and an internal surface of convex cross section, the bushing ring being disposed axially outward of the annular packing; and means for urging the bushing ring axially inward against the packing.
Claim 3
Dependent Claim
44 words
The bearing as recited in claim 1, wherein the urging means further comprises: a drive plate axially contacting the bushing ring at the outward end thereof; and a spring, acting between the drive plate and the housing for urging the drive plate axially inward.
Claim 4
Dependent Claim
17 words
The bearing as recited in claim 1, wherein the packing comprises a plurality of rings containing graphite.
Claim 5
Dependent Claim
98 words
A self-aligning bearing for supporting a rotatable elongated shaft passing through a fixed frame or the like, comprising: a cylindrical housing, disposed about the shaft and forming an annular gap therebetween, the housing further being sealingly secured to the frame; an annular packing, disposed within the annular gap for forming a gas-tight seal between the shaft and the housing; means, for retaining the packing against axially inward movement; a bushing ring, closely fitting within the housing and having an inner surface of convex axial cross section; and means for urging the bushing ring axially inward against the packing.
Claim 6
Dependent Claim
98 words
A self-aligning bearing for supporting a rotatable elongated shaft passing through a fixed frame or the like, comprising: a cylindrical housing, disposed about the shaft and forming an annular gap therebetween, the housing further being sealingly secured to the frame; an annular packing, disposed within the annular gap for forming a gas-tight seal between the shaft and the housing; means, for retaining the packing against axially inward movement; a bushing ring, closely fitting within the housing and having an inner surface of convex axial cross section; and means for urging the bushing ring axially inward against the packing.
Claim 7
Dependent Claim
43 words
The bearing as recited in claim 4, wherein the urging means further comprises: a drive plate, disposed about the shaft outward of the bushing ring; and a spring, acting between the drive plate and the housing for urging the drive plate axially inward.
Claim 8
Dependent Claim
22 words
The bearing as recited in claim 5, wherein the packing contains graphite for lubricating the bushing ring during rotation of the shaft.
