Abstract
L’invention se rapporte à un palier (20) à roulement comprenant une cavité (60) d’amortissement radial par film d’huile délimitée par une surface (50) comprenant des évidements (70) de perturbation de l’écoulement d’huile qui se succèdent circonférentiellement. Figure pour l’abrégé : Fig. 4The invention relates to a rolling bearing (20) comprising a cavity (60) for radial damping by an oil film delimited by a surface (50) comprising recesses (70) for disturbing the oil flow which follow each other circumferentially. Figure for abstract: Fig. 4
