Rolling bearing assembly and rotary machine comprising such a rolling bearing assembly

摘要

This rolling bearing assembly (A) comprises a rotatable element (R) adapted to rotate with respect to a non-rotatable element (B) around a central rotation axis (X-X'), and rolling systems (20, 22, 40) arranged between the rotatable element (R) and the non-rotatable element (B), said rolling systems comprising at least one rolling system having rolling elements (20) arranged along radial axes (X2) with respect to the rotation axis (X-X') of the rolling bearing assembly (A). The rolling bearing assembly comprises at least one elastic ring (14) forming a raceway track mounted on the non-rotatable element (B) so that the rolling elements (20) cooperate with the elastic ring (14). The rolling bearing assembly comprises cooperating retaining means (140, 18; 146, 30) formed on the elastic ring (14) and the non-rotatable element (B) adapted to block the elastic ring (14) in radial translation with respect to the non-rotatable element (B).
