The invention provides a safety anti-clamping stagnation structure suitable for an ultra-high-speed electric steering engine, and the structure comprises a power assembly, a transmission assembly, a body and a stop block assembly; the transmission assembly is mounted on the body, the stop block assembly is arranged between the transmission assembly and the body, the power assembly is in driving connection with the transmission assembly, and the stop block assembly is in driving connection with the transmission assembly. The stop block assembly comprises a base, a damping piece and an upper supporting seat; the damping piece is installed on the base through the upper supporting seat. The elastic damping piece is adopted, so the collision between worm gear teeth and mechanical limiting is gentle, and the elastic damping piece deforms so as to absorb most kinetic energy, so the impact force borne by a worm gear and a worm is smaller, the probability that the structure is stuck is reduced, and the universality is good.
本发明提供了一种适用于超高速电动舵机的安全防卡滞结构,包括动力组件、传动组件、本体以及挡块组件,所述传动组件安装在所述本体上,所述挡块组件设置在传动组件和本体之间,所述动力组件与所述传动组件驱动连接,所述挡块组件包括底座、阻尼件以及上支撑座,所述阻尼件通过上支撑座安装在所述底座上,本发明通过采用弹性阻尼件,使得蜗轮轮齿与机械限位的碰撞较为缓和,弹性阻尼件发生形变从而吸收大部分动能,蜗轮蜗杆受到的冲击力较小,从而降低了结构卡死的几率,普适性好。
