Abstract

EL METODO CONSISTE EN LOS PASOS SIGUIENTES: SE PREPARA UN DISCO DE CHAPA METALICA (28) CON UN AGUJERO CENTRAL (299 COAXIAL A UN EJE (8); SE SOMETE AL DISCO (28) A AL MENOS UNA OPERACION DE ESTIRADO PARA FORMAR UN CUERPO ONDULADO (36) QUE TENGA AL MENOS UNA PRIMERA SERIE DE ONDULACIONES RADIALES (34) QUE DEFINEN UN PRIMER A PRIMERA SERIE DE PALETAS (7) DEL VENTILADOR (6); Y SE SOMETE AL CUERPO ONDULADO (36) A UNA SEGUNDA OPERACION DE ESTIRADO PARA CAMBIAR LA DIMENSION TRANSVERSAL DE CADA UNA DE LAS PALETAS (7) Y FORMAR ASI EL VENTILADOR (6). EN CONCRETO, EN EL PRIMER PASO DE ESTIRADO SE FORMAN PALETAS (7) CON LADOS AXIALMENTE CONVERGENTES, TENIENDO CADA UNA DE ELLAS UN PAR DE PAREDES LATERALES CONVERGENTES QUE SE MIRAN ENTRE SI (11) Y UNA PARED CONVERGENTE (12) QUE CONECTA LAS PAREDES LATERALES (11). Y LAS PALETAS (7) SE FORMAN DEFORMANDO PORCIONES DEL DISCO (28) EN LA MISMA DIRECCION.
