Abstract
Un palier hydrodynamique comporte un arbre (21) monté rotatif dans un logement cylindrique (31), un jeu étant ménagé entre l'arbre (21) et le logement (31) pour qu'un film de lubrifiant s'interpose pendant le mouvement relatif de l'arbre et du logement. L'arbre (21) comporte au moins une zone de courbure réduite (24) orientée de telle sorte qu'un effort maximal (40) prévu soit dirigé vers ladite zone de courbure réduite (24).
