The invention discloses an aircraft landing gear down lock guiding and deviation rectifying device and a down lock, the aircraft landing gear down lock guiding and deviation rectifying device comprises a lock arm and a lock shell, a guiding block assembly is installed on the lock shell, the guiding block assembly is installed at the final limiting position when the lock arm is locked, and the guiding block assembly comprises a guiding face; the guide surface is formed by the circumferential surfaces of the first pin rollers which are rotationally mounted in parallel; a deviation rectifying assembly is installed on the side, deviating from the heading direction, in a lock arm inlet of the lock shell and comprises a rotationally-installed second roller, a deviation rectifying face is formed by the circumferential face of the second roller, and when locking is conducted, when the motion trail of the lock arm deviates towards the rear side of the heading direction, the deviation rectifying face of the second roller is deviated towards the rear side of the heading direction. When the lock arm enters the lock shell, the lock arm firstly makes contact with the second pin roller of the deviation rectifying assembly, under the action of the second pin roller and the landing gear folding and unfolding load, the track of the lock arm gradually returns to the normal track, and then the lock arm makes contact with the first pin roller of the guide block assembly till the final limiting position.

    本发明公开了一种飞机起落架下位锁导向纠偏装置及下位锁,其包括锁臂和锁壳,所述锁壳上安装导向块组件,所述导向块组件安装在所述锁臂上锁时的最终限位位置,所述导向块组件包括导向面,所述导向面由并列转动安装的第一滚柱的圆周面形成;所述锁壳的锁臂入口内的背离航向侧安装纠偏组件,所述纠偏组件包括转动安装的第二滚柱,所述第二滚柱的圆周面形成纠偏面,上锁时,当所述锁臂的运动轨迹往航向后侧方向发生偏移时,所述锁臂在进入所述锁壳过程中先接触到所述纠偏组件的第二滚柱,在第二滚柱以及起落架收放载荷作用下,所述锁臂的轨迹逐渐往正常轨迹上回归,随后,所述锁臂与所述导向块组件的第一滚柱接触直到最终限位位置。
