Abstract

L’invention concerne un roulement (1) à rouleaux comprenant une première bague (3), une seconde bague (2), lesdites bagues (2, 3) étant coaxiales et en rotation relative autour d’un axe central (X1), une rangée de rouleaux (4). La première bague (3) comprenant également une rainure circonférentielle (81, 101, 201, 301) pourvue à une surface (37) radialement opposée au premier chemin de roulement (32), et d’au moins un trou (82, 83, 102, 103, 202, 203, 302, 303) traversant sensiblement radialement ladite bague (3) et débouchant à proximité du premier chemin de roulement (32). La première bague (3) comprend également une rainure secondaire (84, 85, 104, 105, 204, 205, 304, 305) s’étendant selon une direction sensiblement radiale et connectant la rainure circonférentielle (81, 101, 201, 301) au trou (82, 83, 102, 103, 202, 203, 302, 303), du lubrifiant pouvant être acheminé depuis la rainure circonférentielle (81, 101, 201, 301) vers le trou (82, 83, 102, 103, 202, 203, 302, 303) par l’intermédiaire de ladite rainure secondaire (84, 85, 104, 105, 204, 205, 304, 305).
