Abstract

Outillage pour extraire un anneau de retenue de turbomachine Outillage pour turbomachine, configuré pour extraire un organe de retenue d’une roue à aubes de turbomachine, la roue à aubes s’étendant autour d’un axe et comprenant un disque, l’organe de retenue (30) permettant le maintien axial d’aubes dans le disque, l’outillage comprenant un outil (10) présentant une surface de came (13) configurée pour coopérer avec l’organe de retenue (30), et l’outil (10) étant configuré pour que sa rotation autour de l’axe de la roue à aubes lorsque la surface de came (13) coopère avec l’organe de retenue (30) entraîne une translation de l’organe de retenue (30) selon la direction radiale. Procédé pour extraire un organe de retenue d’une roue à aubes de turbomachine. Figure pour l’abrégé : Fig. 2.Tooling for extracting a turbomachine retaining ring Tooling for a turbomachine, configured to extract a retaining member from a turbomachine impeller, the impeller extending around an axis and comprising a disc, the member of retainer (30) allowing the blades to be axially held in the disk, the tool comprising a tool (10) having a cam surface (13) configured to cooperate with the retainer (30), and the tool ( 10) being configured so that its rotation around the axis of the impeller when the cam surface (13) cooperates with the retaining member (30) causes a translation of the retaining member (30) according to the radial direction. A method of extracting a retainer from a turbomachine impeller. Figure for the abstract: Fig. 2.
