Abstract

La presente invención se refiere a una sección de rotor (10) para el rotor de una turbomáquina, en la periferia exterior de la cual se encuentran provistas ranuras de soporte de alabes (16) que se extienden en dirección axial del rotor y en los cuales está dispuesto un alabe de rotor (18) en cada caso, con una base de alabe (20) que corresponde a la ranura de soporte de alabe (16), con superficies de contacto (34) que apuntan radialmente hacia adentro y provistas en cada caso en los alabes (18), en donde para conducir un medio refrigerante a lo largo del lado frontal de la superficie del rotor (28), elementos hermetizantes en forma de láminas (30) se apoyan en la superficie de contacto (34) por medio de fuerza centrífuga y donde para asegurar los elementos hermetizantes (30) contra un desplazamiento en la dirección circunferencial al menos uno de los elementos hermetizantes (30) tiene una apertura (44) provista en el elemento hermetizante (30) para recibir un elemento de bloqueo (46, 62), y en donde se provee de un agujero (58) que coincide con el orificio (44), y para un elemento de bloqueo (46, 62) que se asienta de forma segura, el cual encaja en el agujero (58) y el orificio (44), caracterizada porque el agujero (58) está dispuesto en la base del alabe (20), y porque el elemento de bloqueo (62) está asegurado contra las pérdidas mediante una lámina de sujeción en forma de Z (66), cuyo primer extremo se encuentra entre el elemento hermetizante (30) y el lado frontal (26) de la base del alabe (20).
