Abstract
L’invention se rapporte à une bride (80) de maintien en position axiale d’un anneau de retenue d’aubes d’une roue mobile de turbine. La bride (80) comprend des rainures (81) circonférentielles configurées pour augmenter le refroidissement d’une extrémité axiale d’appui (84) de cette bride (80) de manière à favoriser le phénomène de mise en tonneau d’un anneau (85) de cette bride (80). De telles rainures (81) permettent de préserver le contact de la bride (80) contre l’anneau de retenue lors du fonctionnement de la turbine et de faciliter le montage à froid de la bride (80). Figure pour l’abrégé : Fig. 3The invention relates to a flange (80) for holding in axial position a retaining ring for the blades of a moving turbine wheel. The flange (80) includes circumferential grooves (81) configured to increase cooling of an axial bearing end (84) of the flange (80) so as to promote barrel rolling of a ring (85 ) of this flange (80). Such grooves (81) help to preserve the contact of the flange (80) against the retaining ring during operation of the turbine and to facilitate the cold mounting of the flange (80). Figure for abstract: Fig. 3
