Abstract

L'invention concerne des joints d'étanchéité, notamment pour arbres tournants. Ce joint, à membrane souple 4 en forme de coupole percée pour le passage de l'arbre, avec un profil continu, est caractérisé par le fait que ladite coupole présente une épaisseur décroissante depuis sa base jusqu'à l'arête de contact 1 avec l'arbre, l'élasticité nécessaire au maintien du contact pouvant être obtenu de par la rigidité propre de la membrane. Application : joints pour arbres en rotation.
