Abstract
Abstract The present invention is concerned with improved ball bearings for clutch mechanism, wherein the bearing races engaged by the balls are impressed in annular members consisting of rolled steel sheet to which a suitable contour is given, members being provided for incorporating the bearings in the clutch mechanism and possibly imparting a self-centering characteristic thereto, means being also provided for making said bearing selflubricating and noiseless in actual service.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
A self-centering integral ball thrust clutch bearing comprising at least two rolled steel sheets with ball races impressed therein forming inner and outer races, a clutch mechanism having a transmission shaft and a control member, a carrier and guide member mounted on said transmission shaft and cooperating with said control member, and a thrust bearing control member cooperating with said mechanism to withdraw the clutch, the ends of each said sheet being bent to constitute spaced end walls with a cavity therebetween, a vibration damping resilient material filling at least one of said cavities, said carrier and guide member having a flange receiving the clutch mechanism control member, assembly means to apply said end walls against said flange, and at least one of the damping material filled cavities being spaced from said carrier member for selfcentering of the thrust bearing by means of said thrust bearing control member.
Claim 2
Dependent Claim
148 words
A self-centering integral ball thrust clutch bearing comprising at least two rolled steel sheets with ball races impressed therein forming inner and outer races, a clutch mechanism having a transmission shaft and a control member, a carrier and guide member mounted on said transmission shaft and cooperating with said control member, and a thrust bearing control member cooperating with said mechanism to withdraw the clutch, the ends of each said sheet being bent to constitute spaced end walls with a cavity therebetween, a vibration damping resilient material filling at least one of said cavities, said carrier and guide member having a flange receiving the clutch mechanism control member, assembly means to apply said end walls against said flange, and at least one of the damping material filled cavities being spaced from said carrier member for selfcentering of the thrust bearing by means of said thrust bearing control member.
Claim 3
Dependent Claim
16 words
A clutch bearing according to claim 1, further comprising baffle means crimped in said end faces.
Claim 4
Dependent Claim
28 words
A clutch bearing according to claim 1, wherein the cavity formed in the sheet having the inner race is filled with a self-lubricating and vibration-damping elastomeric synthetic material.
Claim 5
Dependent Claim
26 words
A clutch the according to claim 1, further comprising a plate secured to the inner race and adapted to be engaged by the clutch control member.
Claim 6
Dependent Claim
35 words
A clutch bearing according to claim 4, wherein said flange of the carrier and guide member is resiliently connected to the end face of the bent end portion of at least one of said sheets.
Claim 7
Dependent Claim
35 words
A clutch bearing according to claim 5, wherein said resilient connection of said flange to said end face comprises elastic clamp means engaging said flange and bearing against the end face of said bearing race.
Claim 8
Dependent Claim
36 words
A clutch bearing according to claim 5, wherein said resilient connection of said flange to said end face comprises at least three resilient members disposed at spaced angular intervals along the outer periphery of said flange.
