Abstract

Le présent exposé concerne un dispositif de maintien pour la maintenance d’une roue à aubes (200) de turbine rotative autour d’un axe de révolution, la roue à aubes (200) comprenant - une pluralité d’aubes (202) configurées pour être montées circonférentiellement autour d’un disque et dont des pieds (203) sont engagés axialement, et radialement retenus sur le disque, et - un outillage de maintien desdites aubes à l’intérieur d’un carter de la turbine et dans une position de montage dans le disque; - une pluralité de secteurs d’anneau de retenue (204) agencés circonférentiellement bout à bout autour de l’axe de révolution et agencés en aval (AV) de la pluralité d’aubes (202) et prévus pour bloquer axialement vers l’aval les aubes (202) dans le disque dans une position de blocage, ledit dispositif comprenant une pluralité de cales de maintien (210) des secteurs en position de blocage des aubes (202). Figure à publier avec l’abrégé : figure 3This presentation relates to a holding device for the maintenance of a turbine blade wheel (200) rotating around an axis of revolution, the blade wheel (200) comprising - a plurality of blades (202) configured to be mounted circumferentially around a disk and whose feet (203) are axially engaged and radially retained on the disk, and - a tool for holding said blades inside a casing of the turbine and in a position of mount in disk; - a plurality of retaining ring sectors (204) arranged circumferentially end to end around the axis of revolution and arranged downstream (AV) of the plurality of blades (202) and provided to block axially downstream the blades (202) in the disc in a blocking position, said device comprising a plurality of holding wedges (210) of the sectors in the blocking position of the blades (202).
