Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
120 words
A roller bearing assembly comprising an inner race, a plurality of rollers disposed over the inner race, an outer race having an inner annular portion defining a flat inner surface To receive said rollers and an outer annular portion securable to a load, the inner annular portion being in engagement with the rollers, the inner and outer annular portions being resiliently and pivotally interconnected along a first side to produce a cantilevered suspension of said inner annular portion and to permit pivotal flexure of the inner annular portion relative to the outer annular portion, and stop means extending partially and substantially radially between the inner and outer portions along a second side to define the limit of said pivotal flexure.
Claim 2
Dependent Claim
120 words
A roller bearing assembly comprising an inner race, a plurality of rollers disposed over the inner race, an outer race having an inner annular portion defining a flat inner surface To receive said rollers and an outer annular portion securable to a load, the inner annular portion being in engagement with the rollers, the inner and outer annular portions being resiliently and pivotally interconnected along a first side to produce a cantilevered suspension of said inner annular portion and to permit pivotal flexure of the inner annular portion relative to the outer annular portion, and stop means extending partially and substantially radially between the inner and outer portions along a second side to define the limit of said pivotal flexure.
Claim 3
Dependent Claim
13 words
The roller bearing assembly defined in claim 1 wherein the rollers are straight.
Claim 4
Dependent Claim
14 words
The roller bearing assembly as defined in claim 1 wherein the rollers are tapered.
Claim 5
Dependent Claim
19 words
The roller bearing assembly defined in claim 1 including a separator for maintaining a predetermined relationship between the rollers.
Claim 6
Dependent Claim
21 words
The roller bearing assembly defined in claim 1 wherein the inner and outer annular portions of the outer race are integral.
Claim 7
Dependent Claim
16 words
The bearing assembly defined in claim 1 wherein the inner and outer annular portions are parallel.
Claim 8
Dependent Claim
23 words
The bearing assembly defined in claim 1 wherein the planes of the inner and outer annular portions intersect at a predetermined acute angle.
Claim 9
Dependent Claim
35 words
The bearing assembly defined in claim 1 wherein the inner and outer annular portions are integrated with one another by means of a resilient joint which is of lesser thickness than the outer annular portion.
Claim 10
Dependent Claim
22 words
The bearing assembly defined in claim 1 wherein the outer annular portion is axially slotted at spaced intervals about the circumference thereof.
Claim 11
Dependent Claim
18 words
The bearing assembly defined in claim 1 wherein the thickness of the inner annular portion is axially nonuniform.
Claim 12
Dependent Claim
24 words
The bearing assembly of claim 1 wherein the stop means for limiting comprises a radially extending lip portion integral with said inner annular portion.
Claim 13
Dependent Claim
80 words
An outer race for use in a tapered roller bearing assembly comprising an outer annular portion and an inner annular portion, the inner annular portion having a flat inner surface to receive tapered rollers in contact therewith, the outer and inner annular portions being integrally formed to define a stress-relieved flexural joint along one common side thereof to permit essentially pivotal displacement of the inner annular portion relative to the outer annular portion in the fashion of a cantilevered beam.
Claim 14
Dependent Claim
80 words
An outer race for use in a tapered roller bearing assembly comprising an outer annular portion and an inner annular portion, the inner annular portion having a flat inner surface to receive tapered rollers in contact therewith, the outer and inner annular portions being integrally formed to define a stress-relieved flexural joint along one common side thereof to permit essentially pivotal displacement of the inner annular portion relative to the outer annular portion in the fashion of a cantilevered beam.
Claim 15
Dependent Claim
18 words
The race defined in claim 12 wherein the inner and outer annular portions intersect at an acute angle.
Claim 16
Dependent Claim
21 words
The race defined in claim 12 wherein the outer annular portion is axially slotted at spaced intervals about the circumference thereof.
Claim 17
Dependent Claim
16 words
The bearing race defined in claim 12 wherein the inner and outer annular portions are parallel.
Claim 18
Dependent Claim
22 words
The race defined in claim 12 including stop means for limiting the essentially radial displacement between the inner and outer annular portions.
