Title
(EN) METHOD FOR REMOVING A ROTOR MEMBER FROM A TURBOENGINE, AND INSTRUMENTATION USEFUL TO CONDUCT THE METHOD
(FR) PROCÉDÉ POUR RETIRER UN ÉLÉMENT DE ROTOR D'UN TURBOMOTEUR, ET INSTRUMENTATION UTILE À LA MISE EN ŒUVRE DU PROCÉDÉ
Abstract
(EN)
Disclosed is a method for removing a rotor member from a turboengine (1). A rotor member (11) of the turboengine comprises a rotor body (110) equipped with running blades provided in running blade rows (112), and a trunnion (113, 114) at each axial end of the rotor body. The method comprises providing the turboengine removing a casing provided around the rotor body, installing a rotor support device (3) below the rotor body to support the rotor member (11), removing the central casing (13), providing a suspension device (5, 51) and connecting the suspension device (5, 51) to the rotor member (11) so as to suspend the rotor member, removing the rotor support device (3), and removing the rotor member (11) by a movement along an axis of the rotor member while at least essentially maintaining an inclination of the axis of the rotor member with respect to the ground.
(FR)
L'invention concerne un procédé pour retirer un élément de rotor d'un turbomoteur (1). Un élément de rotor (11) du turbomoteur comprend un corps de rotor (110) comportant des aubes fonctionnelles disposées en rangées d'aubes fonctionnelles (112), et un tourillon (113, 114) à chaque extrémité axiale du corps de rotor. Le procédé consiste à disposer le turbomoteur, à retirer un carter disposé autour du corps de rotor, à installer un dispositif de support de rotor (3) au-dessous du corps de rotor pour supporter l'élément de rotor (11), à retirer le carter central (13), à disposer un dispositif de suspension (5, 51) et à relier le dispositif de suspension (5, 51) à l'élément de rotor (11) de façon à suspendre l'élément de rotor, à retirer le dispositif de support de rotor (3), et à retirer l'élément de rotor (11) par un mouvement le long d'un axe de l'élément de rotor tout en maintenant au moins sensiblement une inclinaison de l'axe de l'élément de rotor par rapport au sol.
