Embodiment Construction

[0031] figure 1 A rolling bearing 1 according to the invention is shown. The rolling bearing 1 comprises an outer ring 3 , an inner ring 5 and rolling elements, which are balls 7 in this example. Each of the outer ring 3 and the inner ring 5 has a raceway for balls 7 arranged in a cage 8 which keeps the balls 7 equidistantly spaced and placed between the outer ring 3 and the inner ring 5 between. The inner ring 5 is solid and comprises concave depressions on its outer surface forming a raceway 50 for the balls 7 . The raceway of the outer ring 3 is formed by two half-raceways. exist figure 1 In the example of , the half raceways of the outer ring 3 are wires 30 and 32 . The outer ring 3 comprises a housing 34 in which the wires 30 and 32 are arranged. The housing 34 comprises an axial portion 340 extending along the axis of rotation XX′ of the rolling bearing 1 . The housing 34 also includes two radial portions 342 and 344 connected to the edges of the axial portion 340...

Abstract

This rolling bearing (1) comprises an outer ring (3) and an inner ring (5), both having a raceway (30, 32, 50) for rolling elements (7) placed between said inner and outer rings (3, 5) in contact with said raceways (30, 32, 50). At least one of the rings (3) comprises an envelope (34) having an axial portion (340) and, connected to the edges of the axial portion (340), two radial portions (342, 344), and two half-raceways (30, 32) arranged in said envelope (34) to form the raceway of this ring (3). The rolling bearing (1) further comprises at least one annular preloading element (9) made of an elastic material and arranged inside the envelope (34) to be preloaded axially between a first radial portion (342) of the envelope (34) and a lateral face (300) of a first half-raceway (30). The rolling bearing (1) comprises at least one damping element (11) radially arranged between the axial portion (340) of the envelope and each of the half-raceways (30, 32).

Description

technical field [0001] The invention relates to a rolling bearing and a method for producing such a rolling bearing. Background technique [0002] From EP-B-1956254 is known a rolling bearing comprising at least one ring provided with two raceways, for example formed of toroidal wire, mounted in a housing and preloaded by an elastic element. Such rolling bearings are commonly used in steering columns to mitigate the effects of column deflection. [0003] The wire used for this type of rolling bearing is made of a linear wire deformed to obtain a circular shape. The ends of the wires engage each other, and the joints generate noise and vibration as the rolling elements roll onto them. It is also known to use raceways with spherical surfaces formed from stamped sheet metal. Noise and vibration can be caused by other causes such as the roughness of the metal contact surfaces. Therefore, the noise emission of rolling bearings of this type should be reduced. Contents of the...
