Asymmetrical triple-row anti-friction bearing
View Patent ↗The invention relates to an anti-friction bearing comprising a first bearing race, a second bearing race and a plurality of anti-friction bodies that are located between the first bearing race and the second bearing race. According to the invention, the anti-friction bearings are arranged in several rows, which are asymmetrical in the longitudinal direction of the anti-friction bearing in relation to any plane that runs perpendicularly to said longitudinal direction of the anti-friction bearing.
1. An anti-friction bearing, comprising:
a first bearing ring
a second bearing ring; and
a plurality of rolling bodies arranged between the first bearing ring and the second bearing ring,
wherein the rolling bodies are ball bearings arranged in an uneven number of rows and the rows are arranged asymmetrically in a longitudinal direction of the anti-friction bearing about an arbitrary plane which is perpendicular to the longitudinal direction of the anti-friction bearing, and
wherein the rolling bodies of each row have different diameters resulting in different pitch circle diameters for each of the rows.
2. The anti-friction bearing as claimed in claim 1 , wherein the plane about which the rolling bodies are arranged asymmetrically is a central plane of the anti-friction bearing.
3. The anti-friction bearing as claimed in claim 1 , wherein at least three rows are provided.
4. The anti-friction bearing as claimed in claim 1 , wherein the pitch circle diameter of at least one row which is situated at the outside with respect to the anti-friction bearing is greater than each of the pitch circle diameters of one of the other rows.
5. The anti-friction bearing as claimed in claim 1 , wherein the axial spacing between a first row and a second row which is adjacent to said first row is smaller than the axial spacing between the second row and a third row which is adjacent to said second row.
6. The anti-friction bearing as claimed in claim 1 , wherein the pitch circle diameter of a carrier-side outer row is greater than each of the pitch circle diameters of one of the other rows.
7. The anti-friction bearing as claimed in claim 1 , wherein the pitch circle diameter of a carrier-side outer row is greater than each of the pitch circle diameters of one of the other rows.
8. The anti-friction bearing as claimed in claim 1 , wherein at least the first bearing ring has a predefined flange-side outer diameter and a carrier-side outer diameter which differs from said flange-side outer diameter.
9. The anti-friction bearing as claimed in claim 1 , wherein the diameters of the rolling bodies of at least two rows are different.
10. The anti-friction bearing as claimed in claim 1 , wherein all the rows have the same pressure angle.
11. The anti-friction bearing as claimed in claim 1 , wherein at least one bearing ring is formed in two parts.
12. The anti-friction bearing as claimed in claim 1 , wherein the raceways of at least one row are arranged on a flange body.
13. A wheel carrier having an anti-friction bearing as claimed in claim 1 .
14. An anti-friction bearing, comprising:
a first bearing ring;
a second bearing ring; and
a plurality of rolling bodies arranged between the first bearing ring and the second bearing ring,
wherein the rolling bodies are ball bearings arranged in an uneven number of rows and the rows are arranged asymmetrically in a longitudinal direction of the anti-friction bearing about an arbitrary plane which is perpendicular to the longitudinal direction of the anti-friction bearing,
wherein the rolling bodies of each row have different diameters resulting in different pitch circle diameters for each of the rows, and
wherein the pressure angles of at least two rows are different.
