Abstract

Abstract A clutch release bearing assembled with a holding ring axially fixed on a sliding sleeve, and with the outer race of the bearing encircling the sleeve; recesses in the outer race engage projections in the holding ring, thereby allowing the outer ring to have relative radial movement without relative rotational movement with respect to the sleeve, and thus permitting self-centering of the bearing on the sleeve.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 99 words
In a clutch release bearing including a sliding sleeve, an outer race encircling said sleeve and provided with a flange oriented toward the axis of the bearing, and a holding ring fixedly mounted on the outer surface of said sliding sleeve, with the outer race being radially displaceable on the sliding sleeve, the improvement in combination therewith wherein said flange includes circumferentially spaced recesses opening toward the axis of the bearing, and said holding ring has projections distributed around and extending from its circumference, which engage said recesses for preventing rotation of the outer race relative to said sleeve.
Claim 2
Dependent Claim 99 words
In a clutch release bearing including a sliding sleeve, an outer race encircling said sleeve and provided with a flange oriented toward the axis of the bearing, and a holding ring fixedly mounted on the outer surface of said sliding sleeve, with the outer race being radially displaceable on the sliding sleeve, the improvement in combination therewith wherein said flange includes circumferentially spaced recesses opening toward the axis of the bearing, and said holding ring has projections distributed around and extending from its circumference, which engage said recesses for preventing rotation of the outer race relative to said sleeve.
Claim 3
Dependent Claim 18 words
A clutch release bearing according to claim 1, wherein said projections extend generally axially from said holding ring.
Claim 4
Dependent Claim 25 words
A clutch release bearing according to claim 2, wherein said holding ring comprises an elastic material, and said projections are integral extensions of said ring.
Claim 5
Dependent Claim 53 words
A clutch release bearing according to claim 3, wherein said bearing includes an inner race with a sealing face, and the elastic holding ring has a substantially axially oriented sealing lip for contacting said face and thus sealing the space between said inner race and the sleeve on which said ring is mounted.
Claim 6
Dependent Claim 36 words
A clutch release bearing according to claim 2, wherein said holding ring is made of thinwalled material and has a radially extending flange which is machined to define said projections which extend integrally from said flange.
Claim 7
Dependent Claim 22 words
A clutch release bearing according to claim 5, wherein said projections machined out of the holding ring are bent to extend axially.
Claim 8
Dependent Claim 14 words
A clutch release bearing according to claim 1, wherein said projections extend radially outward.
Claim 9
Dependent Claim 29 words
A clutch release bearing according to claim 7, wherein said holding ring has an axial flange which is machined to define said projections which extend integrally from said flange.
Claim 10
Dependent Claim 162 words
In a clutch release bearing including a sleeve and outer and inner race rings and captive rolling elements, the improvement in combination therewith wherein said sleeve has a first portion with a first outer diameter and adjacent thereto a flange extending radially outward, said outer race ring has a flange extending radially inward with a bore of second diameter greater than said first diameter and situated radially outward of said first portion with an annular space defined therebetween, and said flanges having radial faces in mutual contact for preventing relative axial movement in a first direction, said bearing further comprising a holding ring axially fixed on said first portion of said sleeve, situated in said annular gap, and having an outer diameter and projections extending from the circumference thereof for engaging said outer race ring flange for preventing relative rotational movement therebetween, said outer race ring bore diameter being greater than said holding ring outer diameter for permitting relative radial movement therebetween.
Claim 11
Dependent Claim 162 words
In a clutch release bearing including a sleeve and outer and inner race rings and captive rolling elements, the improvement in combination therewith wherein said sleeve has a first portion with a first outer diameter and adjacent thereto a flange extending radially outward, said outer race ring has a flange extending radially inward with a bore of second diameter greater than said first diameter and situated radially outward of said first portion with an annular space defined therebetween, and said flanges having radial faces in mutual contact for preventing relative axial movement in a first direction, said bearing further comprising a holding ring axially fixed on said first portion of said sleeve, situated in said annular gap, and having an outer diameter and projections extending from the circumference thereof for engaging said outer race ring flange for preventing relative rotational movement therebetween, said outer race ring bore diameter being greater than said holding ring outer diameter for permitting relative radial movement therebetween.
Claim 12
Dependent Claim 14 words
A bearing according to claim 9, wherein said holding ring projections extend radially outward.
Claim 13
Dependent Claim 13 words
A bearing according to claim 9 wherein said holding ring projections extend axially.
Claim 14
Dependent Claim 64 words
A bearing according to claim 9, wherein said outer ring race flange has a second radial face remote from the face engaging the flange of said sleeve, and wherein said holding ring includes a flange extending radially outward for engaging said second radial face for preventing relative axial movement of said sleeve and outer ring race in a direction opposite said first axial direction.
Claim 15
Dependent Claim 144 words
In a clutch release bearing including a sleeve and outer and inner race rings and captive rolling elements, the improvement in combination therewith wherein said sleeve has a first portion with a first outer diameter, said outer race ring has a flange extending radially inward with a bore of second diameter greater than said first diameter and situated radially outward of said first portion with an annular space defined between adjacent surfaces of said bore and said first portion, said bearing further comprising a holding ring axially fixed on said first portion of said sleeve, situated in said annular gap, and also comprising means extending from one of said adjacent surfaces for engaging the other of said surfaces for preventing relative rotational movement therebetween, said outer race ring bore diameter being greater than said holding ring outer diameter for permitting relative radial movement therebetween.
Claim 16
Dependent Claim 144 words
In a clutch release bearing including a sleeve and outer and inner race rings and captive rolling elements, the improvement in combination therewith wherein said sleeve has a first portion with a first outer diameter, said outer race ring has a flange extending radially inward with a bore of second diameter greater than said first diameter and situated radially outward of said first portion with an annular space defined between adjacent surfaces of said bore and said first portion, said bearing further comprising a holding ring axially fixed on said first portion of said sleeve, situated in said annular gap, and also comprising means extending from one of said adjacent surfaces for engaging the other of said surfaces for preventing relative rotational movement therebetween, said outer race ring bore diameter being greater than said holding ring outer diameter for permitting relative radial movement therebetween.
