Abstract

L'invention concerne un palier comportant une bague extérieure rotative (1) supportée sur un jeu de rouleaux (3) par rapport à une bague intérieure (2) avec un ou plusieurs dispositifs de charge de lubrifiant (7) adaptés pour faciliter la purge contrôlée de la graisse usagée en provenance des cages de palier (3A). Chaque dispositif de charge de lubrifiant (7) est assujetti sur une pièce rotative du palier, en une relation opérationnelle avec une surface fixe adjacente (2A), et comprend une surface de prise au piège (14A) définissant une région de prise au piège de graisse (14). Quand le dispositif de charge de lubrifiant (7) est porté par rotation devant un ou plusieurs orifices de ports de purge de graisse (9), la graisse usagée accumulée à l'intérieur de la région de prise au piège de graisse (14) est forcée dans l'orifice (9) par la surface de prise au piège (14A) à des fins d’extraction ultérieure au travers du port de purge (8).
