Abstract
Un palier en élastomère comprenant une cage interne, une cage externe et une alternance de couches d'élastomère et d'armatures de séparation interposées entre les cages est caractérisé en ce que le palier (10) est sensiblement sphérique, il peut tourner autour d'un axe longitudinal (20), il comprend deux extrémités axiales (22, 24) , il est tronqué à l'une au moins de ses extrémités (22, 24) pour permettre le fixation d'un organe rotatif à la cage interne (12) et les couches d'élastoère ont une section droite transversale non circulaire dans un plan normal à l'axe, en donnant lieu ainsi à la formation de lobes axiaux 25. Application au système rotor pour hélicoptère.
