Abstract

Joint (200) annulaire d’étanchéité pour une turbomachine d’aéronef, le joint s’étendant autour d’un axe (X) et étant compressible en direction axiale, le joint ayant en section axiale une forme générale en V et comportant deux lèvres annulaires (21, 22) reliées par leur périphérie interne (23), chacune de ces lèvres comportant une première surface (24a, 24b) annulaire en regard de l’autre des lèvres et une seconde surface (25a, 25b) annulaire opposée, les secondes surfaces annulaires des lèvres étant configurées pour prendre appui sur des surfaces annulaires afin d’assurer une étanchéité entre ces surfaces, le joint étant caractérisé en ce que la seconde surface d’au moins une des lèvres a une forme générale tronconique et s’évase radialement vers l’extérieur depuis sa périphérie interne, cette seconde surface comportant au moins deux repères (26, 27, 28) visuels de forme annulaire qui s’étendent autour de l’axe à des diamètres différents.
