Abstract

Ensemble électriquement conducteur (10) pour un palier (1) disposé autour d'un arbre (2) et disposé à l'intérieur d'un logement (3). L'ensemble conducteur (10) comporte un élément de retenue annulaire (12) pouvant être accouplé à une bague extérieure (5) de palier (1) ou au logement (3) de palier (1) et ayant un axe central (LC) et une extrémité intérieure ouverte définissant une rainure annulaire (13). Au moins deux et de préférence plusieurs conducteurs (14) présentent chacun une extrémité radialement extérieure (14a) disposée à l'intérieur de la rainure (13) de l'élément de retenue (12) et une extrémité radialement intérieure (14b) pouvant être mise en contact avec l'arbre (2). Chaque conducteur (14) est formé d'une pluralité de fibres conductrices (20) agencées de manière à s'étendre radialement vers l'intérieur depuis l'extrémité intérieure de l'élément de retenue (12). Les au moins deux conducteurs (14) sont espacés circonférentiellement autour de l'axe central de manière à définir au moins deux passages axiaux (22) entre l'élément de retenue (12) et l'arbre (2). De préférence, les conducteurs sont séparés par des éléments d'espacement (16) formés de fibres conductrices (24) ayant chacune une longueur plus courte que la longueur des fibres (20) des conducteurs (14).
