Abstract

L'invention concerne un rouet (1) de compresseur centrifuge comprenant une jante (2) qui se prolonge dans la direction axiale du rouet et vers l'amont par une virole annulaire amont (3) et qui se prolonge, dans la direction radiale du rouet, vers l'extérieur, par un voile (5) muni d’aubes (53, 54) solidaires de sa face amont et vers l'intérieur, par un premier anneau de fixation radiale (6), qui s'étend dans un plan perpendiculaire à l'axe longitudinal du rouet et qui présente, en section axiale, une forme en queue d'aronde. Ce rouet est remarquable en ce qu'il comprend un deuxième anneau de fixation radiale (7), qui s'étend dans un plan perpendiculaire à l'axe longitudinal du rouet, en amont dudit premier anneau de fixation radiale (6) et depuis la face radialement intérieure du voile, ce deuxième anneau de fixation radiale présentant en section axiale, une forme en queue d'aronde. Application dans les compresseurs de turbomachines. Figure pour l’abrégé : figure 7The invention relates to an impeller (1) for a centrifugal compressor comprising a rim (2) which extends in the axial direction of the impeller and upstream by an upstream annular ring (3) and which extends in the radial direction of the impeller. impeller, outwards, by a web (5) provided with vanes (53, 54) integral with its upstream face and inwards, by a first radial fixing ring (6), which extends in a plane perpendicular to the longitudinal axis of the impeller and which has, in axial section, a dovetail shape. This spinning wheel is remarkable in that it comprises a second radial fixing ring (7), which extends in a plane perpendicular to the longitudinal axis of the spinning wheel, upstream of said first radial fixing ring (6) and from the radially inner face of the web, this second radial fixing ring having, in axial section, a dovetail shape. Application in turbomachine compressors. Figure for the abstract: figure 7
