Abstract
Abstract A bearing assembly incorporating at least one planetary race element between sets of bearings which are radially spaced and differentially sized. A preferred embodiment utilizes raceways the bearing surfaces of which are equidistantly and successively offset from a common plane of reference.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
232 words
A bearing assembly, including inner and outer race elements and at least one intermediately disposed planetary race element, one of said inner and outer race elements being adapted to be rotatably driven and the other to be fixed, said rice elements being constructed as segments of cylinders and orienting concentrically of one another with their geometric centers essentially in a common plane perpendicular to the assembly axis, first and second sets of rolling bearings positioned respectively between the inner race element and the planetary race element and between the planetary race element and the outer race element placing said race elements in a disconnected, radially spaced relation, and raceways in said race elements receiving said sets of bearings and positioning them to occupy said common plane, the raceways in said planetary race element being formed to provide an inclining sUrface on each of the inner and outer peripheries of such element, each inclining surface terminating at its one end generally in said common plane and extending therefrom in a direction opposed to the direction of extension of the other surface, said planetary race element having on each periphery radially displaced but adjacent surfaces parallel to one another and to the assembly axis merging at adjacent ends with the ends of a respective inclining surface to define relatively shallow inversely disposed raceways at the inner and outer peripheries of said planetary race element.
Claim 2
Dependent Claim
232 words
A bearing assembly, including inner and outer race elements and at least one intermediately disposed planetary race element, one of said inner and outer race elements being adapted to be rotatably driven and the other to be fixed, said rice elements being constructed as segments of cylinders and orienting concentrically of one another with their geometric centers essentially in a common plane perpendicular to the assembly axis, first and second sets of rolling bearings positioned respectively between the inner race element and the planetary race element and between the planetary race element and the outer race element placing said race elements in a disconnected, radially spaced relation, and raceways in said race elements receiving said sets of bearings and positioning them to occupy said common plane, the raceways in said planetary race element being formed to provide an inclining sUrface on each of the inner and outer peripheries of such element, each inclining surface terminating at its one end generally in said common plane and extending therefrom in a direction opposed to the direction of extension of the other surface, said planetary race element having on each periphery radially displaced but adjacent surfaces parallel to one another and to the assembly axis merging at adjacent ends with the ends of a respective inclining surface to define relatively shallow inversely disposed raceways at the inner and outer peripheries of said planetary race element.
Claim 3
Dependent Claim
31 words
A bearing assembly according to claim 1 wherein said rolling bearings are ball bearings, said inclining surfaces are arcuate and formed on radii having their centers generally in said common plane.
Claim 4
Dependent Claim
27 words
A bearing assembly according to claim 1, wherein the inner and outer race elements have raceways substantially diametrically opposed to respective raceways in said planetary race element.
Claim 5
Dependent Claim
125 words
A bearing assembly according to claim 1, wherein a subassembly comprising the inner race element and the said first set of rolling bearings has a slip fit in said planetary race element with said first set of bearings seating between the raceway in the inner element and the raceway in the inner periphery of the planetary element, and wherein said subassembly with the said second set of bearings mounted thereon and seating to the raceway in the outer periphery of said planetary race element has a slip fit in said outer race element with said second set of bearings seating to the raceway therein, and there are means for maintaining the defined elements and bearings in an assembled relation to form a unitary bearing assembly.
Claim 6
Dependent Claim
44 words
A bearing assembly according to claim 3, wherein said last named means provides a connection between said inner and outer race elements and forms therewith an enclosure in protective relation to said planetary race element and said first and second sets of rolling bearings.
Claim 7
Dependent Claim
47 words
A bearing assembly according to claim 3, wherein said last-named means comprises annular plate elements interengaged at their inner and outer peripheral edges with said inner and outer race elements respectively to be in an interconnected relation thereto and in end closing relation to the bearing assembly.
Claim 8
Dependent Claim
115 words
A bearing assembly according to claim 6, wherein said inner race element is constructed as a hub for securing to a rotary shaft or the like and said outer race element is constructed for application as a relatively stationary bearing case, said hub having on its exterior longitudinally spaced-apart circumferential grooves aligning with corresponding grooves formed in the inner periphery of the outer case, the edges of said plate elements interfitting in said grooves and placing said plate elements in confining relation to said planetary race member, said planetary race member being so dimensioned and disposed to lie within the boundaries of planes occupied by said plate elements and as defined by said aligning grooves.
Claim 9
Dependent Claim
90 words
A bearing assembly according to claim 6, wherein said inner race element is formed with a set of longitudinally spaced-apart circumferential grooves aligned with a corresponding set of grooves in the outer race element, said inner and outer elements having radially displaced surfaces on opposite sides of respective raceways therein wherein said sets of grooves are formed, the grooves of each set being spaced apart a distance exceeding the length of the cylinder segment defining said planetary race member, the peripheral edges of said plate elements interfitting in said grooves.
