Abstract

SE INDICA UN DISPOSITIVO PARA LA SEGURIDAD DE FUNCIONAMIENTO AXIAL DEL ALABE Y PARA LA ELIMINACION DE LA DESCOMPENSACION DEL ROTOR PARA EL COMPRESOR AXIAL O TURBINAS DE MOTOPROPULSORES DE TURBINAS DE GAS, EN EL QUE LOS ALABES (1) DE FUNCIONAMIENTO CON SUS BASES (2) SE ANCLAN EN RANURAS (3) AXIALES DEL DISCO (4) DE LA RUEDA DISTRIBUIDOS POR LA PERIFERIA; POR LO QUE CADA RANURA AXIAL INCLUYE UNA CAVIDAD (T) FORMADA ENTRE LA BASE DE LA RANURA Y EL EXTREMO DE LA BASE; EN CADA CAVIDAD SE COLOCA UNA PIEZA (5) DE RELLENO INSTALADA SOBRE LA BASE DE LA RANURA Y UNA CHAPA (6) DE SEGURIDAD QUE PUENTEA ENTRE EL EXTREMO DE LA BASE Y LA PIEZA DE RELLENO UNA GRIETA (S) QUE PASA A LO LARGO DE LA CAVIDAD, QUE SE DOBLA EN AMBOS EXTREMOS ALINEADOS DE FORMA OPUESTA Y QUE SOBRESALEN DE LA CAVIDAD FRENTE A LA SUPERFICIE FRONTAL, EL DISCO DE RUEDA Y LA BASE DEL ALABE, POR LO QUE UNA DESCOMPENSACION DEL ROTOR SE COMPENSA EN PESO A TRAVES DE UNA PIEZA DE RELLENO.
