Abstract
Abstract A rolling bearing comprising two coaxial elements rotatable one with respect to the other by way of two rows of rolling bodies which roll in rolling races in these elements is described. The rolling bodies of one row are located at an axial distance from the rolling bodies of the other row of greater than 20 percent of the diameter of one rolling body; a first of said two rotatable elements consists of two rings of sheet metal joined together on each of which is formed a rolling race for said rolling bodies, and the second of said two rotatable elements is formed from a single ring of sheet metal on which the other two rolling races for said rolling bodies are formed, one of said other two rolling races of the second rotatable element being formed on an annular part of the second element which is bent over on the inside of the element.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
208 words
A rolling bearing comprising: a first and a second coaxial element rotatable one with respect to the other and provided with rolling races; two rows of rolling bodies which roll in said rolling races, the rolling bodies of one row being located at an axial distance from the rolling bodies of the other row of greater than 20 percent of the diameter of one rolling body of the rows and the normals at the points of contact of each of the rolling races with the relative rolling bodies pertaining to one conical surface the vertex of which is located on the opposite side of the vertex of the other conical surface with respect to a plane normal to the axis of the bearing; said first rotatable element consisting of two rings of sheet metal joined together on each of which is formed a rolling race for said rolling bodies; said second rotatable element being formed from a single ring of sheet metal on which two rolling races for said rolling bodies are formed, and one of said two rolling races of the second rotatable element being formed on an annular part of the second element which is bent inside of a central substantially cylindrical part of the element.
Claim 2
Dependent Claim
208 words
A rolling bearing comprising: a first and a second coaxial element rotatable one with respect to the other and provided with rolling races; two rows of rolling bodies which roll in said rolling races, the rolling bodies of one row being located at an axial distance from the rolling bodies of the other row of greater than 20 percent of the diameter of one rolling body of the rows and the normals at the points of contact of each of the rolling races with the relative rolling bodies pertaining to one conical surface the vertex of which is located on the opposite side of the vertex of the other conical surface with respect to a plane normal to the axis of the bearing; said first rotatable element consisting of two rings of sheet metal joined together on each of which is formed a rolling race for said rolling bodies; said second rotatable element being formed from a single ring of sheet metal on which two rolling races for said rolling bodies are formed, and one of said two rolling races of the second rotatable element being formed on an annular part of the second element which is bent inside of a central substantially cylindrical part of the element.
Claim 3
Dependent Claim
109 words
A rolling bearing as claimed in claim 1, wherein said central substantially cylindrical pArt, and a flanged part orthogonal to said cylindrical part and said annular part, said annular part defining, with said central cylindrical part, an annular cavity internal to the second rotatable element, the other of said two races of the second rotatable element being formed between said central cylindrical part and said flanged part and the second rotatable element being configured in such a manner that its profile in a section taken on a diametrical plane of said element is intersected at only one point by a straight line parallel to the axis of the element.
Claim 4
Dependent Claim
71 words
A rolling bearing as claimed in claim 1, wherein each of said two rings of the first rotatable element comprises a flanged part orthogonal to the axis of the element, each of said rings being configured in such a manner that its profile in a section taken on a diametrical plane of said ring is intersected at only one point by a straight line parallel to the axis of the ring.
Claim 5
Dependent Claim
50 words
A rolling bearing as claimed in claim 1, wherein one of said rings of the first rotatable element is provided with a substantially cylindrical part on which a ring of soft material is mounted provided with an annular lip arranged to rest on the flanged part of said second element.
