Abstract

L'invention concerne une roue mobile de turbine (20) pour turbomachine d'aéronef, la roue comprenant un disque (21) et un anneau (16) de rétention axiale des aubes, l'anneau étant équipé d'un système de verrouillage (80) configuré pour retenir l'anneau axialement par rapport au disque. Dans une configuration verrouillée de l'anneau, le système de verrouillage (80) adopte une position verrouillée dans laquelle ses premier et second éléments de butée (76, 86) enserrent axialement l'anneau (16) et une bride de fixation (60) solidaire du disque, le système de verrouillage étant déplaçable de cette position verrouillée à une position déverrouillée amenant le second élément de butée (86) axialement en regard d'un orifice de passage (66) traversant la bride (60), de manière à autoriser l'introduction du second élément (86) dans cet orifice de passage.The invention relates to a mobile turbine wheel (20) for an aircraft turbomachine, the wheel comprising a disc (21) and a ring (16) for axial retention of the blades, the ring being equipped with a locking system ( 80) configured to retain the ring axially relative to the disc. In a locked configuration of the ring, the locking system (80) assumes a locked position in which its first and second stopper members (76, 86) axially enclose the ring (16) and a clamp (60). integral with the disc, the locking system being movable from this locked position to an unlocked position bringing the second stop element (86) axially facing a passage orifice (66) passing through the flange (60), so as to allow the introduction of the second element (86) into this passage orifice.
