Abstract
L’invention concerne un dispositif (100) de montage d’un axe (1) sur une chape (2) pour une turbomachine d’aéronef, comportant une chape (2) comportant deux oreilles (3, 4) comprenant des alésages de passage (5, 6) de l’axe (1), une première douille (7) engagée de manière ajustée et coulissante dans un premier des alésages (5, 6), une seconde douille (8) engagée de manière ajustée et coulissante dans un second des alésages (5, 6), l’axe (1) comportant une tête (10) serrée axialement contre la première douille (7) et un écrou serré (11) axialement contre la seconde douille (8). Selon l’invention, les alésages (5, 6) ont des diamètres internes (Di1, Di2) différents et le premier alésage (5) comprend un épaulement annulaire (15) ayant un diamètre interne (Di15) inférieur au diamètre interne (Di1) de cet alésage (5). L’invention concerne aussi une turbomachine d’aéronef, comportant au moins un tel dispositif (100). Figure pour l’abrégé : Figure 1The invention relates to a device (100) for mounting an axle (1) on a yoke (2) for an aircraft turbomachine, comprising a yoke (2) comprising two lugs (3, 4) comprising passage bores. (5, 6) of the axle (1), a first bush (7) fitted and slidably engaged in a first of the bores (5, 6), a second bush (8) fitted and slidably engaged in a second of the bores (5, 6), the axis (1) comprising a head (10) clamped axially against the first sleeve (7) and a nut tightened (11) axially against the second sleeve (8). According to the invention, the bores (5, 6) have different internal diameters (Di1, Di2) and the first bore (5) comprises an annular shoulder (15) having an internal diameter (Di15) less than the internal diameter (Di1) of this bore (5). The invention also relates to an aircraft turbomachine, comprising at least one such device (100). Figure for the abstract: Figure 1
