Abstract (en)
[origin: WO0224411A1] The invention concerns a method for transverse ultrasound peening of blades (2) on a rotor which consists in driving in rotation the wheel (3) bearing the blades (2) about its geometrical axis (6) arranged substantially vertically and in causing the blades (2) to pass through a mist of microbeads produced by a vibrating surface (20) in an active chamber (12) arranged laterally relative to the wheel. The active surface (20) is located beneath the path of the blades (2). Preferably, the active chamber (12) comprises a second vibrating surface above the path of the blades (2). The invention also concerns a machine for implementing said method.
Abstract (fr)
Le procédé de grenaillage transversal par ultrasons des aubes (2) sur un rotor consiste à faire tourner la roue (3) portant les aubes (2) autour de son axe géométrique (6) disposé sensiblement à la verticale et à faire passer les aubes (2) dans un brouillard de microbilles entretenu par une surface vibrante (20) dans une enceinte active (12) disposée latéralement à la roue. La surface active (20) se trouve sous le chemin des aubes (2). De préférence l'enceinte active (12) comporte une deuxième surface vibrante au-dessus du chemin des aubes (2). L'invention concerne également une machine pour la mise en oeuvre du procédé. <IMAGE>
