Abstract

L'invention concerne un procédé de montage de plusieurs injecteurs (24) de turbomachine (10) sur un carter (14) externe d'une chambre (12) à combustion de la turbomachine (10), un joint (46a, 46b) annulaire étant intercalé entre une bride (34) de fixation de chaque injecteur (24) et le carter (14) externe, la turbomachine (10) comportant des joints (46a, 46b) d'au moins deux modèles différents, le procédé comportant pour chaque injecteur (24) une étape (E1) de préhension d'un joint (46a, 46b) du modèle correspondant, caractérisé en ce qu'il comporte une étape (E2) de détrompage suivant chronologiquement l'étape (E1) de préhension qui consiste à vérifier que le joint (46a, 46b) saisi lors de l'étape (E1) de préhension est conforme au modèle de joint requis pour le montage dudit injecteur (24). Figure pour l'abrégé : Figure 8The invention relates to a method for mounting several injectors (24) of a turbomachine (10) on an outer casing (14) of a combustion chamber (12) of the turbomachine (10), an annular joint (46a, 46b) being interposed between a flange (34) for fixing each injector (24) and the external casing (14), the turbomachine (10) comprising seals (46a, 46b) of at least two different models, the method comprising for each injector (24) a step (E1) of gripping a joint (46a, 46b) of the corresponding model, characterized in that it includes a step (E2) of keying chronologically following the step (E1) of gripping which consists verifying that the joint (46a, 46b) entered during step (E1) of gripping conforms to the model of joint required for mounting said injector (24).
