Abstract

EL EJE DEL CIGUEÑAL PARA UN MOTOR DE COMBUSTION INTERNA COMPRENDE GUALDERAS DOTADAS DE ESCOTADURAS, LAS CUALES ESTAN CONFORMADAS, SIMETRICAMENTE RESPECTO A UN PLANO VERTICAL LONGITUDINAL CENTRAL Y OPUESTAS ENTRE SI, DENTRO DE UN CONTORNO EXTERIOR DELGADO DE LAS GALDERAS. EN LA ZONA DE LAS ESCOTADURAS, LOS TRAMOS ESTAN CONFORMADOS CON UN PERFIL DE SECCION CON FORMA DE U CON FLANCOS LATERALES. ENTRE LAS ESCOTADURAS CONFORMADAS EN DISPOSICION SOBREPUESTA, SE DISPONE UNA NERVIACION RIGIDIZANTE EN LA ZONA DE SOLAPAMIENTO DEL VASTAGO DEL CIGUEÑAL Y DEL VASTAGO DEL RODAMIENTO. UNA PRECISA DISPOSICION DE LAS ESCOTADURAS EN CADA GUALDERA POSIBILITA UNA REDUCCION DE PESO CON UNA EFECTIVA COMPENSACION DE MASA. LAS ESCOTADURAS ESTAN ESPECIALMENTE SOBREPUESTAS, DE MODO QUE SE CREA UNA SECCION LO MAS GRANDE POSIBLE EN LAS ZONAS DE PELIGRO DE CADA GUALDERA, A PESAR DE SER LAS ESCOTADURAS MAXIMAMENTE GRANDES. ESTAS SECCIONES PUEDEN ABSORBER DEFINIDAMENTE LA RIGIDEZ DE FLEXION Y DE TORSION.
