Abstract

UN METODO PARA REPARAR EL ROTOR DE UN TURBOGENERADOR. UN METODO PARA REPARAR EL ROTOR DE UN TURBOGENERADOR QUE PRESENTA AGRIETAMIENTO DE LA PUNTA DE LOS DIENTES, EN EL QUE DESPUES DE SACAR EL ROTOR DEL ESTATOR Y LOS ANILLOS DE RETENCION EXISTENTES, SE PROTEGE EL DEVANADO CON MATERIALES DE CUBIERTA ADECUADOS, INCLUYENDO SELLAR EL CONJUNTO CON PARAFINA, SE MECANIZA EN SECO TODA LA ZONA DE ENCAJADURA A UNA GEOMETRIA OPTIMA, SE QUITAN LAS REBABAS DE LA ZONA MECANIZADA Y, DESPUES DE QUITAR LAS REBABAS Y LOS MATERIALES CUBIERTA Y SELLADO, SE INSTALAN NUEVOS ANILLOS DE RETENCION. LA PRINCIPAL VENTAJA ES LA POSIBILIDAD DE REALIZAR EL METODO EN EL SITIO.
