Abstract

Un ensamble de bloque para una hilera de paletas de entrada radiales (62) de una turbo-maquina. Una paleta de entrada (66) incluye una porcion de raiz (74) que tiene una forma de union axial (78) para acoplarse con una ranura orientada axialmente que tiene una forma de union axial (78) para el acoplamiento con la ranura orientada axialmente que tiene una forma de union axial (76) formada en la posicion de ranura de entrada (34) para la entrada radial del disco de rotor (56). Para aplicaciones que utilizan paletas con caras de plataforma curvas (112), la paleta anterior (108) y la siguiente paleta (110) en la hilera se disenan con una cara curva para empotrar con las paletas de entrada radial adyacentes y una cara plana (129) para empotrar las caras de paleta de cierre planas (116). La paleta de cierre (84) puede estar disenada con una porcion de raiz (88) que tenga dos patas (90, 92) que se separan por medio de un llave (86) para que hagan contacto estrecho con las paletas adyacentes. Una paleta de cierre (62) substancialmente identica a las paletas de entrada radial puede fijarse en la posicion de la ranura de entrada con un miembro de conexion (96) que tiene una porcion interna radial (98) que tiene una forma de union axial y una porcion exterior radial (100) que tiene una forma de union radial. Una falla en una porcion perimetrica de una disco de rotor de entrada radial (56) puede repararse sin soldadura al remover la falla adjunto con el material colindante para formar una forma de union axial en el disco del rotor, y luego instalar la paleta de cierre con una forma de union axial complementara en la zona de reparacion.
