Title (EN) CONNECTING ROD FOR A TURBINE ENGINE, WITH AN INTEGRATED FILTER, AND PRODUCTION METHOD THEREOF
(FR) BIELLE DE TURBOMACHINE A FILTRE INTEGRE ET SON PROCEDE DE REALISATION
Abstract:
(EN) The invention relates to a connecting rod (100), in particular for a turbine engine, comprising an intermediate body (102) with a general elongate shape, connected at the longitudinal ends thereof to connecting heads (104) comprising holes (106) having axes (A) that are, for example, substantially parallel. The connecting rod is characterised in that the heads are assembled or formed as a single piece with at least one part of the body and at least one of the heads comprises an alveolar annular part (108), about the axis of the hole, forming a vibrating filter and having a flexural and/or compressive deformation capacity greater than that of the rest of the connecting rod and, in particular, that of the body.
(FR) Bielle (100), en particulier pour une turbomachine, comprenant un corps intermédiaire (102) de forme générale allongée et reliée à ses extrémités longitudinales à des têtes de liaison (104) comportant des orifices (106) dont les axes (A) sont par exemple sensiblement parallèles, caractérisée en ce que lesdites têtes sont assemblées ou formées d'une seule pièce avec au moins une partie dudit corps et au moins l'une d'entre elles comporte, autour de l'axe de son orifice, une partie annulaire alvéolaire (108) formant un filtre vibratoire et ayant une capacité de déformation en compression et/ou en flexion supérieure à celle du reste de la bielle et en particulier à celle dudit corps.
