Abstract

L'invention concerne un ensemble palier générateur d'énergie (100) comprenant un sous-ensemble générateur d'énergie (200, 300) intégré dans un palier (110). Le sous-ensemble générateur d'énergie (300) utilise le mouvement relatif entre une bague intérieure (112) et une bague extérieure (116) du palier (110) pour générer de l'énergie électrique. Un élément d'étanchéité (136) est fixé à une extrémité des paliers (112, 116). Le sous-ensemble générateur d'énergie (300) comprend un générateur (320) monté à travers une ouverture (137) de l'élément d'étanchéité (136) dans une partie intérieure du palier (110) et positionné de manière à coopérer fonctionnellement avec un matériau polarisé magnétiquement (324). Le matériau polarisé magnétiquement (324) est intégré dans une bague magnétique (138) fixée à la bague du palier qui ne comporte pas l'élément d'étanchéité. Le mouvement relatif entre les bagues (112, 116) coopère avec le générateur (310) et le matériau polarisé magnétiquement (324) de façon qu'un noyau (312) du générateur (320) génère un courant électrique.
