Abstract

UN APARATO Y UN METODO PARA USO EN TURBINAS DE VAPOR, DEL TIPO QUE EMPLEA ALABES DE ENTRADA AXIAL, COMPRENDE UNA PLURALIDAD DE ANILLOS ELASTICOS DISPUESTOS EN UNA HENDIDURA EXTENDIDA EN GENERAL AXIALMENTE EN LA BASE DE CADA RAIZ DE ALABE. LOS ANILLOS PRESIONAN CADA RAIZ RADIALMENTE HACIA FUERA DE MODO QUE REDUCEN AL MINIMO EL ALETEO DEL ALABE DURANTE EL FUNCIONAMIENTO DEL MECANISMO EN GIRO.
