A circumferential seal for sealing (29) between a rotating shaft (12} and a stationary housing (34) circumscribing the shaft (12). The seal (29) comprises a stator (31) mounted to said housing (34) and having a radially inward facing carbon (36) portion and a rotor with a ceramic sealing (49) member having a radially outward facing surface in rubbing contact with said carbon portion (36). The rotor also includes a metal clamping means (52) for mounting the ceramic sealing member (49) to the shaft (12). The clamping means (52) includes an axial flexible clamping member and a radial flexible clamping member that together clamp onto a mounting flange (58) of the ceramic sealing member (49) when exposed to the compressive force of a lockup assembly.
Cette invention concerne un joint d'étanchéité circonférentiel conçu pour réaliser l'étanchéité (29) entre un arbre rotatif (12) et un carter fixe entourant ledit arbre (12). Ce joint (29) comporte un stator (31) monté sur ledit carter (34) et doté d'une partie en carbone (36) disposée radialement vers l'intérieur et un rotor doté d'un élément d'étanchéité (49) en céramique ayant une surface disposée radialement vers l'extérieur en contact par frottement avec ladite partie en carbone (36). Ledit rotor comporte également un organe de blocage métallique (52) conçu pour le montage de l'élément d'étanchéité (49) en céramique sur l'arbre (12). Cet organe de blocage (52) comporte un élément de blocage axial flexible et un élément de blocage radial flexible qui se bloquent ensemble sur une bride de montage (58) de l'élément d'étanchéité (49) en céramique lorsqu'ils sont exposés à la force de compression d'un ensemble de verrouillage.
