Abstract

Se describe un ensamble de sello para una turbina de gas que se configura en ranuras de un blindaje de calor del rotor (4) que tienen varios dobleces. El ensamble comprende cuatro porciones de sello (11a, b hasta 14a, b) traslapados uno al otro y extendidos en la dirección axial, radial, y circunferencial con respecto al rotor de la turbina. Un medio de retención (15) mantiene las secciones radiales de una porción de sello (13a) que permite un movimiento limitado de la porción de sello (13a) independiente de la otra porción de sello (12a). El movimiento independiente asegura el contacto de las porciones de sello individuales (11a, b-14a, b) con todas las superficies ajustadas del blindaje de calor del rotor (4) y mejora la función de sellado sin tener en cuenta los desplazamientos del blindaje de calor del rotor y las tolerancias de las partes de turbina.
