Abstract
SE PRESENTA UN METODO Y UN DISPOSITIVO PARA CONTROLAR EL HUECO DE LA PUNTA DE LA PALA EN UNA MAQUINA GIRATORIA EN LOS QUE LA MAQUINA COMPRENDE UNA PARTE DE TURBINA (1) Y UNA PARTE DE COMPRESOR (4) SEPARADA DE LA PARTE DE LA TURBINA. EL ALOJAMIENTO DEL ESTATOR (15) DE LA PARTE DE LA TURBINA ESTA FORMADO DE UN CONO ESTACIONARIO (16). LA INVENCION SE CARACTERIZA EN QUE UNO O MAS DISCOS DE TURBINA (2) PROVISTOS DE PALAS (5), DURANTE UN FUNCIONAMIENTO NO CONSTANTE, POR EJEMPLO DURANTE EL ARRANQUE, LA PARADA Y LOS CAMBIOS DE CARGA, SE MUEVEN FUERA DEL CONO DEL ESTATOR DE MANERA QUE EL HUECO DE LA PUNTA DE LA PALA SE INCREMENTE Y DE QUE LOS DISCOS DE LA TURBINA DURANTE EL FUNCIONAMIENTO CONTINUO SE MUEVAN AL INTERIOR DEL CONO DEL ESTATOR DE MANERA QUE SE REDUZCA EL HUECO DE LA PUNTA DE LA PALA.
