Abstract

L’invention concerne un rotor dont un disque aubagé monobloc pourvu d’au moins une masselotte (170) d'équilibrage. La partie amont de la plateforme du disque présente une bride (72). La masselotte (170) présente une surface (171) pouvant venir en butée sous pression contre une surface radialement intérieure (660a) de la plateforme et est montée sur la bride par l’intermédiaire d’un élément de fixation (76) qui traverse un orifice de la bride (72) et la masselotte (170). L’élément de fixation (76) comprend une vis (78) venant en appui contre une surface amont de la jante (68) du disque aubagé. Figure à publier avec l’abrégé : [Fig. 5]The invention relates to a rotor having a single-piece bladed disc provided with at least one balancing weight (170). The upstream part of the platform of the disc has a flange (72). The weight (170) has a surface (171) capable of abutting under pressure against a radially inner surface (660a) of the platform and is mounted on the flange by means of a fixing element (76) which passes through an orifice of the flange (72) and the weight (170). The fixing element (76) comprises a screw (78) bearing against an upstream surface of the rim (68) of the bladed disc. Figure to be published with the abstract: [Fig. 5]
