Abstract
(EN)
A rolling bearing, comprising an outer ring (1), an inner ring (5), and a first rolling body (2) located between the outer ring (1) and the inner ring (5). The first rolling body (2) is designed as a tapered roller. The rolling bearing further comprises at least one second rolling body (6; 6'; 6'') located between the outer ring (1) and the inner ring (5), wherein the first rolling body (2) has a first self-rotation axis, and the second rolling body (6; 6'; 6'') has a second self-rotation axis. On at least one same axial position of the rolling bearing, the diameter of the second rolling body (6; 6'; 6'') in a cross section perpendicular to the second self-rotation axis is greater than the diameter of the first rolling body (2) in a cross section perpendicular to the first self-rotation axis. The rolling bearing is capable of preventing slippage when the load borne by the rolling bearing decreases.

La présente invention concerne un palier à roulement comprenant une bague externe (1), une bague interne (5) et un premier corps de roulement (2) situé entre la bague externe (1) et la bague interne (5). Le premier corps de roulement (2) est réalisé sous la forme d'un rouleau conique. Le palier à roulement comprend en outre au moins un second corps de roulement (6 ; 6' ; 6'') situé entre la bague externe (1) et la bague interne (5), le premier corps de roulement (2) présentant un premier axe d'auto-rotation et le second corps de roulement (6 ; 6' ; 6'') présentant un second axe d'auto-rotation. Sur au moins une même position axiale du palier à roulement, le diamètre du second corps de roulement (6 ; 6' ; 6'') dans une section transversale perpendiculaire au second axe d'auto-rotation est supérieur au diamètre du premier corps de roulement (2) dans une section transversale perpendiculaire au premier axe d'auto-rotation. Le palier à roulement est capable d'empêcher un dérapage lorsque la charge portée par le palier à roulement diminue.

一种滚动轴承,包括外圈(1)、内圈(5)和位于外圈(1)和内圈(5)之间的第一滚动体(2),第一滚动体(2)被设计为圆锥滚子,其中,滚动轴承还具有至少一个位于外圈(1)和内圈(5)之间的第二滚动体(6;6';6"),其中,第一滚动体(2)具有第一自旋转轴线,第二滚动体(6;6';6")具有第二自旋转轴线,其中,在滚动轴承的至少一个相同的轴向位置上,第二滚动体(6;6';6")在垂直于第二自旋转轴线的截面内的直径大于第一滚动体(2)在垂直于第一自旋转轴线的截面内的直径。该滚动轴承能够防止在其所承载的载荷变小时发生打滑。
