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. Figure pour l'abrégé : Figure 2Annular seal (200) for an aircraft turbomachine, the seal extending around an axis (X) and being compressible in the axial direction, the seal having a general V shape in axial section and comprising two lips annular (21, 22) connected by their internal periphery (23), each of these lips comprising a first annular surface (24a, 24b) facing the other of the lips and a second opposite annular surface (25a, 25b), the second annular surfaces of the lips being configured to bear on annular surfaces in order to ensure a seal between these surfaces, the seal being characterized in that the second surface of at least one of the lips has a generally frustoconical shape and flares radially outwards from its internal periphery, this second surface comprising at least two visual markers (26, 27, 28) of annular shape which extend around the axis at different diameters.
