Abstract
Abstract A cage for rolling elements of a double row rolling bearing comprising a circumferentially-extending annular member, a plurality of generally parallel fingers projecting axially from said annular member and circumferentially spaced apart to define a plurality of pockets for the rolling elements, each of said pockets including a means for spacing the rolling elements in side-by-side relation to form the two rows of rolling elements, each of said fingers being spaced apart adjacent the terminal ends remote from said annular member and being formed adjacent to the terminal ends thereof to retain the rolling elements in sideby-side relation, said fingers being resilent so that the cage may be assembled axially relative to the rolling elements.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
137 words
A cage for the rolling elements of a double-row rolling bearing comprising a circumferentially extending annular member, a purality of generally parallel fingers projecting axially from said annular member and circumferentially spaced apart to define a plurality of pockets for the rolling elements, each of said pockets including means for spacing the rolling elements in sideby-side relation to form the two rows of rolling elements, each of said fingers being spaced apart adjacent the terminal ends remote from said annular member and being formed adjacent the terminal ends thereof to retain the rolling elements in side-byside relation, said fingers being resilient so that the cage may be assembled axially relative to said rolling elements, the portion of said fingers confronting said rolling elements being concave so that the cage is carried and centered by the rolling elements.
Claim 2
Dependent Claim
137 words
A cage for the rolling elements of a double-row rolling bearing comprising a circumferentially extending annular member, a purality of generally parallel fingers projecting axially from said annular member and circumferentially spaced apart to define a plurality of pockets for the rolling elements, each of said pockets including means for spacing the rolling elements in sideby-side relation to form the two rows of rolling elements, each of said fingers being spaced apart adjacent the terminal ends remote from said annular member and being formed adjacent the terminal ends thereof to retain the rolling elements in side-byside relation, said fingers being resilient so that the cage may be assembled axially relative to said rolling elements, the portion of said fingers confronting said rolling elements being concave so that the cage is carried and centered by the rolling elements.
Claim 3
Dependent Claim
20 words
A cage according to claim 1, characterized thereby that the fingers partly surround the rolling elements, thereby centering the cage.
Claim 4
Dependent Claim
37 words
A cage according to claim 1, characterized thereby that the distance between the free ends of the fingeRs are diminished by projections, abutments or like which are elastically compressed or deformed during the mounting of the cage.
