Embodiment Construction

[0013] Refer now figure 1 A gasket for rolling bearings, especially for rolling bearings of automobile wheels, is described.

[0014] The bearing includes a fixed component, a rotating component and some rolling elements. The rolling elements are placed in a rolling space formed between the components so that they can rotate relatively.

[0015] In order to seal one side of the rolling space, the bearing is equipped with a gasket, which includes a rigid ring frame 1 combined with the bearing, so that the frame is connected to a member of the bearing in rotation. In particular, the frame 1 can be realized with a metal material, especially a stamped steel plate. According to an embodiment, each side of the rolling space can be sealed with a gasket.

[0016] In the illustrated embodiment, the skeleton 1 includes an axial support surface 1a and a radial support surface 1b, which are connected by a connecting fillet 1c. In this way, by assembling on the corresponding supporting surface ...

Abstract

The invention relates to a roller bearing comprising a fixed body and a rotating body and roller bodies arranged in a roller space, formed between said bodies to permit relative rotation thereof, at least one side of the roller space being provided with a sealing joint having a sealing element (2) associated with a rigid annular assembly (1) fixed to a bearing body, said sealing element having an outer lip (4) and an inner lip (3) in sliding contact with a respectively outer (8b) and inner (8a) surface fixed to the other bearing body, said lips being arranged to define between them an annular housing in which a lubricant (9) is arranged, in which the outer surface (8b) has a bearing capacity of more than 60% and a roughness of 0.5 ¢mu!m, the bearing capacity and the roughness of the inner surface (8a) are respectively always larger and always smaller than that of the outer surface (8b).

Description

Technical field [0001] The invention relates to a rolling bearing, at least one side of the rolling space is equipped with a gasket, and also relates to a gasket used for the rolling bearing. [0002] The invention is particularly suitable for sealing at least one side of the rolling space of automobile rolling bearings, especially wheel bearings. Background technique [0003] In order to avoid the leakage of lubricant in the rolling space on the one hand and the pollution of the space by external contaminants on the other hand, it has been known to use gaskets, which include a flexible sealing element combined with a rigid skeleton for use with Bearing combination. [0004] In particular, the flexible element may have an outer lip and an inner lip, defining an annular groove therebetween in which the lubricant is placed. In this way, by frictionally contacting the lip connected to one member of the bearing with the supporting surface connected to the other member of the bearing, t...
