Abstract
Abstract A rolling bearing having two coaxial elements rotatable one with respect to the other by way of two rings of rolling bodies which roll on races in these elements is described. The two rings are of different diameters and the rolling bodies of one ring are situated at an axial distance from the rolling bodies of the other ring of not greater than 20 percent of the diameter of a rolling body of the ring which comprises rolling bodies of small dimensions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
A rolling bearing comprising: a first and second coaxial elements rotatable one with respect to the other and provided with rolling races; two rings of rolling bodies which roll on said rolling races of each elements; said two rings being of different diameter and the rolling bodies of one ring being situated at an axial distance from the rolling bodies of the other ring of not greater than 20 percent of the diameter of a rolling body of the ring which comprises rolling bodies of smaller dimensions; on said first element there being formed two of said rolling races for said rolling bodies, one for each of said rings, the normals at the points of contact of each of the races with the relative rolling bodies pertaining to the same conical surface the vertex of which is situated on the other side of the vertex of the other conical surface with respect to a plane normal to the axis of the bearing; and on said second element there being formed other two of said rolling races for said rolling bodies on each of which the rolling bodies of one of said two rings roll.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
A rolling bearing as claimed in claim 1, wherein the centres of the rolling bodies of both said rings lie in a single plane normal to the axis of the bearing.
Claim 4
Dependent Claim
24 words
A rolling bearing as claimed in claim 1, wherein the semiangle of said two conical surfaces is the same and is equal to 45*.
Claim 5
Dependent Claim
29 words
