Abstract

La invención se refiere a un procedimiento para producir un árbol del cigüeñal, en especial para motores diesel, en el que se produce un árbol del cigüeñal de fundición a partir de hierro fundido dúctil templado bainíticamente, estando sometida la pieza de fundición a tratamiento térmico adaptado al hierro fundido dúctil templado bainíticamente, por lo que la pieza de fundición adquiere una elevada dureza y resistencia. De acuerdo con la invención, superficies que forman superficies de soporte para bielas y cojinetes del árbol son de menor tamaño antes del tratamiento térmico ADI. Tras el tratamiento térmico, se aplica un recubrimiento a las superficies de soporte, adaptándose el espesor de la capa a la disminución de tamaño y desviaciones dimensionales como resultado del tratamiento térmico. Las superficies de soporte recubiertas se someten finalmente a un mecanizado de acabado al tamaño final sin necesidad de mecanizar las superficies de soporte de la pieza de fundición tras el tratamiento térmico.
