Abstract

L’invention concerne un jonc (2) d’assemblage s’étendant circonférentiellement autour d’un axe (X), ledit jonc (2) étant destiné au couplage en rotation d’une première pièce (3) et d’une seconde pièce (4) d’une turbomachine, caractérisé en ce que le jonc (2) comporte une première partie (8) coopérant par emboitement avec la première pièce (3), et une seconde partie (9) coopérant par emboitement avec la seconde pièce (4), de façon à assurer le couplage en rotation de la première pièce (3) par rapport à la seconde pièce (4), ledit jonc (2) étant élastiquement déformable entre une position de fonctionnement dans laquelle ledit jonc (2) présente un premier diamètre et une position de montage ou de démontage dans laquelle ledit jonc (2) présente un second diamètre, inférieur ou supérieur au premier diamètre, le jonc (2) présentant un plan axial médian (P) et comportant au moins une zone creuse (14) qui s’étend circonférentiellement de part et d’autre du plan axial médian (P). Figure à publier avec l’abrégé : Figure 4The invention relates to an assembly rod (2) extending circumferentially around an axis (X), said rod (2) being intended for the coupling in rotation of a first part (3) and a second part (4) of a turbomachine, characterized in that the rod (2) comprises a first part (8) cooperating by interlocking with the first part (3), and a second part (9) cooperating by interlocking with the second part ( 4), so as to ensure the rotational coupling of the first part (3) relative to the second part (4), said rod (2) being elastically deformable between an operating position in which said rod (2) has a first diameter and a mounting or dismounting position in which said ring (2) has a second diameter, smaller or greater than the first diameter, the ring (2) having a median axial plane (P) and comprising at least one hollow zone ( 14) which extends circumferentially on either side of the median axial plane (P).
