Abstract

L’invention se rapporte à un palier (20) à roulement comprenant une cavité (60) formant des compartiments (60A, 60B) qui se succèdent axialement de manière à former un film d’amortissement fluidique ayant plusieurs sections adjacentes. Figure pour l’abrégé : Fig. 2The invention relates to a rolling bearing (20) comprising a cavity (60) forming compartments (60A, 60B) which succeed one another axially so as to form a fluidic damping film having several adjacent sections. Figure for abstract: Fig. 2
