Title (EN) RING FOR CONTROLLING A STAGE OF VARIABLE-SETTING VANES FOR A TURBINE ENGINE
(FR) ANNEAU DE COMMANDE D'UN ÉTAGE D'AUBES À CALAGE VARIABLE POUR UNE TURBOMACHINE
Abstract: front page image
(EN)The invention relates to a ring (36) for controlling a stage of variable-setting vanes for a turbine engine, including at least one member (40) for resting on the casing and attachment means (52, 64) for attaching said member, which comprise a socket (64) including an axial bore (66) for passing said member or a supporting element (52) for supporting said member, a through-slot (68) leading into said bore and configured to allow a substantially radial deformation of the socket, and an outer thread (70) for screwing the socket into a complementary thread (58) of an opening (56) of said body, said socket being configured such that, during the screwing thereof, it deforms from a first position in which said member or mounting can be mounted and moved in said bore, until a second position in which said socket is radially stressed and tightly mounted on said member or mounting, which is thus immobilised with respect to the socket. The invention also relates to a stage of variable-setting vanes (14) for a turbine engine and to a turbine engine comprising such a control ring (36).
(FR)Anneau (36) de commande d'un étage d'aubes à calage variable pour une turbomachine, comportant au moins un organe (40) d'appui sur le carter et des moyens de fixation (52, 64) de cet organe, qui comprennent une douille (64) comportant un alésage axial (66) de passage dudit organe ou d'un élément (52) de support dudit organe, une fente (68) traversante débouchant dans ledit alésage et configurée pour autoriser une déformation sensiblement radiale de la douille, et un filetage externe (70) de vissage de la douille dans un filetage (58) complémentaire d'un orifice (56) dudit corps, ladite douille étant configurée de sorte que, lors de son vissage, elle se déforme depuis une première position dans laquelle ledit organe ou support peut être monté et déplacé dans ledit alésage, jusqu'à une seconde position dans laquelle ladite douille est contrainte radialement et montée serrée sur ledit organe ou support qui est ainsi immobilisé vis-à-vis de la douille. Etage d'aubes à calage variable (14) pour turbomachine et turbomachine comprenant un tel anneau de commande (36).
