Abstract

La invención se refiere a un dispositivo que comprende un árbol del cigüeñal (100) y al menos una biela (200) que tiene una cabeza (202) montada sobre un apoyo de bancada (102) del árbol del cigüeñal (100). El apoyo de bancada (102) y la cabeza (201) de la biela (200) comprenden superficies de apoyo (108, 202) que están en contacto próximo entre sí en un área de soporte de cargas que soporta las fuerzas que actúan entre la cabeza (201) de la biela y apoyo de bancada (102) cuando el dispositivo es operado. De acuerdo con invención, la superficie de apoyo (108) del apoyo de bancada (102) en su área de soporte de cargas presenta un perfil curvado de modo cóncavo en la sección del árbol longitudinal y la superficie de apoyo de la cabeza (201) presenta un perfil convexo que está en contacto próximo con el perfil cóncavo del apoyo de bancada (102).
