Abstract

Procédé d'assemblage d'un secteur d'anneau de distributeur sur une structure fixe d’une turbine, et secteur d’anneau associé L’invention concerne un procédé d'assemblage d'un secteur d'anneau (10) d'un distributeur d’une turbine, le secteur d’anneau comprenant un aubage fixe (11) et un mât (26) à insérer dans un logement intérieur (20) de l’aubage fixe, le mât comportant une platine à fixer à une structure fixe (24) de la turbine, le procédé comportant : une étape de mesure, au cours de laquelle un positionnement du secteur d’anneau par rapport à la structure fixe est déterminé ;une étape de détermination d’une rectification à appliquer à une interface entre la platine du mât et la structure fixe pour obtenir un positionnement nominal du secteur d’anneau; etune étape de rectification de l’interface entre la platine du mât et la structure fixe, conformément à la rectification à appliquer déterminée précédemment. Figure pour l’abrégé : Figure 1Method for assembling a distributor ring sector on a fixed structure of a turbine, and associated ring sector The invention relates to a method for assembling a ring sector (10) of a distributor of a turbine, the ring sector comprising a fixed blading (11) and a mast (26) to be inserted into an internal housing (20) of the fixed blading, the mast comprising a plate to be fixed to a fixed structure (24) of the turbine, the method comprising: a measuring step, during which a positioning of the ring sector relative to the fixed structure is determined; a step of determining a rectification to be applied to an interface between the plate of the mast and the fixed structure to obtain a nominal positioning of the ring sector; and a step of rectification of the interface between the plate of the mast and the fixed structure, in accordance with the rectification to be applied determined previously.
