Abstract

En un bloque 20 cilíndrico se proporciona una parte 26 de pared de soporte que soporta de forma giratoria un cigüeñal. La parte 26 de pared de soporte tiene una parte 28 de rebaje de ajuste a la que puede ajustarse una tapa 50 de cojinete. En cada una de las partes de la esquina izquierda y derecha donde una superficie 28a inferior y una superficie 28b de ajuste de la parte 28 de rebaje de ajuste se cruzan, se forma una ranura 29 de muesca que se extiende en la dirección de disposición de los orificios cilíndricos y tiene una sección transversal sustancialmente en forma de arco cuando es cortada por el plano virtual a lo largo de la dirección de extensión de la misma. Como resultado, la tensión que tiene un mayor valor a medida que la ubicación se acerca a la parte central en la dirección de extensión de la ranura 29 de muesca puede ser sustancialmente uniforme en la dirección de extensión de dicha ranura 29 de muesca, y es posible mitigar efectivamente la concentración de tensión.
