Abstract

La invención se refiere a una disposición de alabes (40), con un soporte de alabes (56) y una ranura de fijación (58) allí colocada, la cual en sus paredes laterales (60) presenta protuberancias (62) que se extienden longitudinalmente para formar cortes posteriores (64) y en la cual se utiliza un número de alabes (25, 27) para formar una corona de alabes de una turbomáquina, en la cual cada alabe (25, 27) junto a una paleta del alabe (48) presenta una base de alabe (50) que se introduce en cortes posteriores (64) para fijarla y mediante un elemento (46) colocado entre el lado inferior de la base de la paleta (68) y una base de ranura (70) de la ranura de fijación (58) que se introduce en las protuberancias (62) Para obtener una fijación especialmente segura, confiable, duradera y de bajo desgaste, que permita un montaje y desmontaje especialmente sencillo se provee que cada elemento (46) tenga forma de placa, presente al menos una canaleta (52, 55) para oprimir hacia abajo y en dirección longitudinal de la ranura de fijación (58) está cubierta parcialmente por la base de alabe (58) que la oprime.
