Abstract

Se describe un montaje de paleta de turbina, en particular para una turbina de gas, que comprende un disco (1) con un eje de rotación (6), paletas de turbina (22) cada paleta de turbina (22) tiene un ala (7), una raíz de paleta (11) y una plataforma (14) entre el ala (7) y la raíz de la paleta (11) por medio de la cual esta se puede fijar al disco (1), a placas de aseguramiento (9) y a bandas de sello dobladas (10). Las paletas de turbina (22) están dispuestas adyacentes una a la otra sobre el disco (1), están presentes espacios entre las plataformas (14) y las paletas de turbina adyacente (22) y las cavidades de raíz (8) entre las porciones de la raíces (11) de las paletas de turbina adyacente (22). Las paletas de turbina (22) están aseguradas axialmente en disco (1) por medio de placas de aseguramiento (9). Las bandas de sello (10) están dispuestas en los espacios entre las plataformas (14) de las paletas de turbina vecinas (22) para sellar el espacio y limitar axialmente sobre la raíz de la paleta (11) y sobre la placa de aseguramiento (9). Adicionalmente, se describe una turbina de gas con un montaje de paleta de turbina de la invención. Además, se describe una banda de sello (10), en particular para uso en un montaje de paleta de turbina de gas, la cual comprende una porción recta (15) y una porción (16) con un doblez. La porción (16) con el doblez es más estrecha con relación a su ancho que la porción recta (15).
