Abstract

Se muestra un ensamble de turbomáquina, que comprende un rotor (1) y un anillo de aspas (7A; 7B) montadas en el rotor; cada aspa comprende una porción aerodinámica (7F) y una porción de raíz (7R) insertada en una ranura de retención de aspa circunferencial (5) del rotor (1); la ranura de retención de aspa (5) comprende una porción de ranura alargada; las aspas en la porción de ranura alargada son giratorias alrededor de un eje generalmente radial respectivo (Y-Y), para tomar una posición de dimensión tangencial mínima; por lo menos un inserto desmontable (21) se coloca a lo largo de la porción de ranura alargada, entre la porción de raíz de las aspas (7B) localizadas en la porción de ranura alargada y una pared lateral de la ranura de retención de aspa, para forzar y bloquear las aspas en una disposición ensamblada final.
