Abstract
Abstract Combined radial and thrust rolling bearing comprising a cylindrical ring of the radial bearing and a radial flange connected to the ring. A localized boss defining an annular face on the flange is adapted to transmit thrust, exerted by a machine part around which the radial bearing is mounted, to an element surrounding the bearing so as to avoid concentration of thrust forces in marginal zones of thrust-transmitting means interposed between the machine part and said flange. The radial flange bears against a plane force-distributing flange which is applied against the element and is part of a sleeve having a skirt portion which surrounds the thrust-transmitting means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
A combined radial rolling bearing and thrust rolling bearing comprising a cylindrical ring of the radial bearing, a radial flange which is connected to said cylindrical ring and has a localized boss defining an annular face and is adapted to transmit thrust, exerted by a shoulder integral with a machine part around which the radial bearing is mounted, to an element surrounding the bearing through said annular face so as to avoid concentration of thrust forces in marginal zones of thrusttransmitting means interposed between said shoulder and said flange, said radial flange bearing against a plane forcedistributing flange which is applied against said element and is part of a sleeve having a skirt portion which surrounds the thrust-transmitting means.
Claim 2
Dependent Claim
119 words
A combined radial rolling bearing and thrust rolling bearing comprising a cylindrical ring of the radial bearing, a radial flange which is connected to said cylindrical ring and has a localized boss defining an annular face and is adapted to transmit thrust, exerted by a shoulder integral with a machine part around which the radial bearing is mounted, to an element surrounding the bearing through said annular face so as to avoid concentration of thrust forces in marginal zones of thrusttransmitting means interposed between said shoulder and said flange, said radial flange bearing against a plane forcedistributing flange which is applied against said element and is part of a sleeve having a skirt portion which surrounds the thrust-transmitting means.
Claim 3
Dependent Claim
36 words
A combined bearing as claimed in claim 1, wherein said plane force-distributing flange has an inner edge which surrounds with clearance the cylindrical part of said ring so that said sleeve is free to move radially.
Claim 4
Dependent Claim
36 words
A combined bearing as claimed in claim 1, wherein said plane force-distributing flange has an inner edge in contact with the cylindrical part of said ring so that the sleeve is centered relative to the latter.
Claim 5
Dependent Claim
28 words
A combined bearing as claimed in claim 3, wherein said force-distributing flange has an inner edge which is an interference fit on the cylindrical part of said ring.
Claim 6
Dependent Claim
40 words
A combined bearing as claimed in claim 3, wherein said skirt portion has a free end portion, sealing means being carried by said free end portion and adapted to cooperate with a face adjacent an outer edge of said shoulder.
Claim 7
Dependent Claim
26 words
A combined bearing as claimed in claim 1, wherein said sleeve and said ring are interconnected by adhesion between said force-distributing flange and said radial flange.
Claim 8
Dependent Claim
32 words
A combined bearing as claimed in claim 1, wherein said thrust-transmitting means are needles and said skirt portion retains a rolling counterplate adapted to be interposed between said shoulder and said needles.
Claim 9
Dependent Claim
16 words
A combined bearing as claimed in claim 1, wherein said thrust-transmitting means is a plate member.
