Abstract

Perfeccionamientos introducidos en una turbina de circulación axial que comprende un rotor, una pluralidad de álabes montados circunferencialmente adyacentes unos a otros sobre dicho rotor, terminando cada álabe en una punta y teniendo sobre él una superficie delantera cóncava, una superficie trasera convexa, un borde delantero y un borde trasero, y teniendo cada álabe un orificio que se extiende a su través desde dicha superficie delantera hasta dicha superficie trasera, medios para amarrar entre sí dichos álabes, incluyendo dichos medios de amarre un miembro de alambre que se extiende entre álabes adyacentes, unos primeros y unos segundos miembros de manguitos anulares (50, 60) fijados a dichos álabes (18) junto a dichos orificios (44, 46), teniendo dichos miembros de manguito (50, 60) sobre ellos unas superficies de asiento semiesféricas (62, 64), y teniendo dichos alambres de amarre (66) junto a sus extremos unas cabezas semiesféricas (72, 74) alojadas por dichas superficies de asientosemiesféricas (62, 64) en dichos miembros de manguitos (50, 60) teniendo dichas cabezas (72, 74) y dichas superficies e asiento (62, 64) una cara intermedia generadora de fricción de manera tal que disipe la energía del movimiento relativo entre álabes adyacentes (18) y limite de este modo la vibración, caracterizados porque el diámetro de dichas cabezas semiesféricas (72, 74) es ligeramente menor que el diámetro de dichas superficies de asiento semiesféricas (62, 64).
