Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
77 words
In a bearing arrangement between a rotating part and a stationary part wherein said bearing arrangement includes an inner race secured to one of said parts and an outer race secured to the other of said parts and a retaining ring supporting a plurality of rolling elements intermediate said inner and outer races, the improvement comprising magnetic means mounted on said retainer ring and one of said parts for eccentrically loading said retaining ring to suppress instability.
Claim 2
Dependent Claim
77 words
In a bearing arrangement between a rotating part and a stationary part wherein said bearing arrangement includes an inner race secured to one of said parts and an outer race secured to the other of said parts and a retaining ring supporting a plurality of rolling elements intermediate said inner and outer races, the improvement comprising magnetic means mounted on said retainer ring and one of said parts for eccentrically loading said retaining ring to suppress instability.
Claim 3
Dependent Claim
36 words
In a bearing arrangement as set forth in claim 1 wherein said magnetic means is comprised of a magnet mounted on one of said parts and a ring of magnetic material mounted on said retaining ring.
Claim 4
Dependent Claim
25 words
In a bearing arrangement as set forth in claim 1 wherein said magnetic means are mounted to impart a radial bias to said retainer ring.
Claim 5
Dependent Claim
25 words
In a bearing arrangement as set forth in claim 1 wherein said magnetic means are mounted to impart an axial bias to said retainer ring.
