Abstract

La présente invention se rapporte à un joint d'étanchéité rotatif globalement circulaire qui crée une étanchéité entre des pièces mécaniques relativement rotatives pour la rétention de lubrifiant et l'exclusion d'agents contaminants de l'environnement, et qui incorpore une géométrie de joint d'étanchéité qui interagit avec le lubrifiant pendant une rotation relative afin de distribuer un film lubrifiant dans l'interface d'étanchéité dynamique. Les caractéristiques d'une taille d'entrée variable, d'une inclinaison de flanc de lèvre dynamique variable, et d'une réduction de l'amplitude et de la partie circonférentiellement orientée de la zone de pression à contact interfacial du côté lubrifiant dans la partie la plus étroite de la lèvre, individuellement ou en association, servent à maximiser la lubrification interfaciale dans des conditions de fonctionnement rudes, et servent également à minimiser la zone de cisaillement de lubrifiant, le couple du joint d'étanchéité, le volume du joint d'étanchéité, et l'usure, tout en garantissant une capacité d'adaptation dans les rainures de joint de l'équipement existant.
