Abstract

UN CUERPO (1) HUECO CON AL MENOS DOS CASQUILLOS (3) OVALADOS Y DE FORMA RESPECTIVA UNA BARRA (4) DE UNION DE FORMA ANULAR QUE SE DISPONE ENTRE LOS CASQUILLOS (3). LA SUPERFICIES PERIMETRICAS EXTERIORES DE LOS CASQUILLOS SE DISPONEN AL MENOS EN LA ZONA DEL RADIO MAS PEQUEÑO A TRAVES DE LA BARRA (4) DE UNION. EL PASO (6) ES MAYOR EN EL PUNTO DEL VERTICE DEL RADIO MENOR QUE EN LAS ZONAS RESTANTES Y EL PERIMETRO DE LA BARRA (4) DE UNION DE FORMA ANULAR ES MENOR QUE EL PERIMETRO DE LOS CASQUILLOS (3) OVALADOS. ESTE CUERPO (1) HUECO SE COMPONE DE MATERIAL DUCTIL. LOS CASQUILLOS (3) Y LA BARRA (4) DE UNION MUESTRAN DE FORMA RESPECTIVA REFUERZOS DE PARED ESENCIALMENTE REGULARES A TRAVES DEL PERIMETRO, DE MODO QUE EL ESPESOR DE PARED DE LA BARRA (4) DE UNION ES MAYOR AL MENOS PARCIALMENTE QUE LA DE LOS CASQUILLOS (3), INCLUSO DE ACUERDO CON UNA CANTIDAD TAL, QUE LA SUPERFICIE DE SECCION TRANSVERSAL DE LOS CASQUILLOS (3) Y DEL BRAZO (4) DE UNION ES IGUAL. LA INVENCION SE REFIERE ADEMAS A UN PROCEDIMIENTO PARA LA ELABORACION DE UN CUERPO (1) HUECO DE ESTE TIPO.
