Embodiment Construction

[0018] Such as figure 1 , which shows an embodiment of a rolling bearing 10 according to a first example of the invention, said rolling bearing (having an axis 12) comprising an outer ring 14, an inner ring 16, a plurality of rolling elements arranged between said rings 18 (balls in this case), and a cage 20 for keeping the rolling elements circumferentially spaced apart. The rolling bearing 10 also comprises an annular seal 22 and an annular seal assembly 24 on each side to close the radial gap existing between these rings 14 , 16 .

[0019] Said inner ring 16 and outer ring 14 are concentric and symmetrical with respect to a transverse radial plane passing through the center of the rolling bearing 10 . The ring is of solid type. One of the rings rotates while the other ring is fixed or also rotates. The outer ring 14 comprises an annular circular raceway formed onto its bore and two annular recesses or grooves formed radially from the bore towards the outside and arrange...

Abstract

The rolling bearing comprises an inner ring 16, an outer ring 14, at least one row of rolling elements 18 disposed between the rings, and at least one sealing subassembly 24 mounted on one o f the rings 16 and provided with a shield 40 extending towards the other ring and with a sealing element 42 axially disposed between said ring and the shield and coming into friction contact against said ring.

Description

technical field [0001] The invention relates to a rolling bearing. Background technique [0002] In rolling bearings, one or more seals or seals are usually used to keep lubricants, such as grease, inside the bearing and to prevent the ingress of foreign bodies. Typically, such a seal or seal is attached to one of the bearing rings and cooperates with the other ring. [0003] International patent application WO-A1-2011 / 121385 (SKF) discloses a rolling bearing comprising an inner ring, an outer ring and two sealing means closing the radial gap existing between these rings. Each sealing arrangement comprises a seal disposed radially between the rings and an annular shroud secured to the inner ring and arranged transversely to the seal so as to define a gap therebetween. The shroud comprises a radial portion in axial contact with the radial surface of the inner ring, which is extended by a curved inner portion arranged in an annular groove formed in the bore of said ring. ...
