Abstract
L’invention concerne un ensemble (100) pour un roulement comprenant :- un palier (20) ayant un axe de rotation (X-X) et comprenant une bague interne fixée à un arbre (1) et une bague externe fixée à un moyeu (2), - une entretoise intra-palier interne (7) annulaire agencée entre la bague interne et l’arbre (1),- une entretoise intra-palier externe (6) annulaire agencée entre la bague externe et le moyeu (2),dans lequel au moins l’une de l’entretoise intra-palier interne (7) et de l’entretoise intra-palier externe (6) présente un coefficient de dilatation thermique d’au moins 10% supérieur au coefficient de dilatation d’une ou plusieurs pièces environnantes de l’entretoise intra-palier interne (7) et/ou de l’entretoise intra-palier externe (6).
