Abstract
Abstract An improved double-row bearing in which two pairs of ballreceiving raceways comprise a first pair of deep groove-bearing raceways, one of which is formed in a unitary ring which also provides a raceway of the other pair, and the other of which is formed by two ring sections, one of which provides the other raceway of the other pair, the other pair and its rolling elements making up an angular-contact bearing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
A double-row bearing including in combination a first unitary bearing ring having spaced generally spherical full-groove raceways therein, a second bearing ring comprising a first section having a partial-groove raceway with its outer shoulder at least partially removed and having a portion of a generally spherical full-groove raceway, a second bearing ring second section having another portion of a generally spherical fullgroove raceway, means for assembling said first ring and said second ring sections with said partial-groove raceway in cooperative relationship with one of said first ring raceways to form a first pair of raceways and with said raceway portions forming a full-groove raceway in cooperative relationship with the other first ring raceway to form a second pair of raceways, a first set of balls located in the raceways of the first pair to form an angular-contact bearing and a second set of balls located in the raceways of the second pair to form a deep-groove bearing.
Claim 2
Dependent Claim
157 words
A double-row bearing including in combination a first unitary bearing ring having spaced generally spherical full-groove raceways therein, a second bearing ring comprising a first section having a partial-groove raceway with its outer shoulder at least partially removed and having a portion of a generally spherical full-groove raceway, a second bearing ring second section having another portion of a generally spherical fullgroove raceway, means for assembling said first ring and said second ring sections with said partial-groove raceway in cooperative relationship with one of said first ring raceways to form a first pair of raceways and with said raceway portions forming a full-groove raceway in cooperative relationship with the other first ring raceway to form a second pair of raceways, a first set of balls located in the raceways of the first pair to form an angular-contact bearing and a second set of balls located in the raceways of the second pair to form a deep-groove bearing.
Claim 3
Dependent Claim
61 words
A double-row bearing as in claim 1 in which said second ring first section forms the inner part of a full-groove raceway, said inner part having an outer edge, the cooperating full-groove raceway of the other pair having an outer edge spaced from the outer edge of the inner part by a distance slightly less than the diameter of a ball.
Claim 4
Dependent Claim
28 words
A double-groove bearing as in claim 1 in which said sections are assembled at an interface, said interface being located adjacent the bottom of said one full-groove raceway.
Claim 5
Dependent Claim
16 words
A double-row bearing as in claim 1 including respective unitary cages for said sets of balls.
Claim 6
Dependent Claim
146 words
A double-row bearing including in combination, a unitary outer bearing ring having spaced full-groove raceways therein, an inner bearing ring comprising a first section having a partial-groove raceway with its outer shoulder at least partially removed and having a portion of a full-groove raceway, a second inner ring section having another portion of a full-groove raceway, means for assembling said outer ring and said inner ring sections with said partial-groove raceway in cooperative relationship with one of said outer ring raceways to form a first pair of raceways and with said raceway portions forming a full-groove raceway in cooperative relationship with the other outer ring raceway to form a second pair of raceways, balls located in the raceways of the first pair to form an angular-contact bearing and a second set of balls located in the raceways of the second pair to form a deep-groove bearing.
Claim 7
Dependent Claim
146 words
A double-row bearing including in combination, a unitary outer bearing ring having spaced full-groove raceways therein, an inner bearing ring comprising a first section having a partial-groove raceway with its outer shoulder at least partially removed and having a portion of a full-groove raceway, a second inner ring section having another portion of a full-groove raceway, means for assembling said outer ring and said inner ring sections with said partial-groove raceway in cooperative relationship with one of said outer ring raceways to form a first pair of raceways and with said raceway portions forming a full-groove raceway in cooperative relationship with the other outer ring raceway to form a second pair of raceways, balls located in the raceways of the first pair to form an angular-contact bearing and a second set of balls located in the raceways of the second pair to form a deep-groove bearing.
Claim 8
Dependent Claim
148 words
A double-row bearing including in combination, a unitary inner ring having spaced full-groove raceways therein, an outer bearing ring comprising a first section having a partial-groove raceway with its outer shoulder at least partially removed and having a portion of a full-groove raceway, a second outer ring section having another portion of a full-groove raceway, means for assembling said inner ring and said outer ring Sections to form two pairs of cooperating raceways, one of said pairs being made up of an inner ring raceway and said partial-groove outer ring raceway, the other pair being made up of the other inner ring raceway and a raceway formed by said raceway portions, a first set of balls in the raceways of the first pair to make up an angular-contact bearing, and a second set of balls located in the raceways of the second pair to form a deep-groove bearing.
Claim 9
Dependent Claim
148 words
A double-row bearing including in combination, a unitary inner ring having spaced full-groove raceways therein, an outer bearing ring comprising a first section having a partial-groove raceway with its outer shoulder at least partially removed and having a portion of a full-groove raceway, a second outer ring section having another portion of a full-groove raceway, means for assembling said inner ring and said outer ring Sections to form two pairs of cooperating raceways, one of said pairs being made up of an inner ring raceway and said partial-groove outer ring raceway, the other pair being made up of the other inner ring raceway and a raceway formed by said raceway portions, a first set of balls in the raceways of the first pair to make up an angular-contact bearing, and a second set of balls located in the raceways of the second pair to form a deep-groove bearing.
