The invention belongs to the technical field of aviation, and relates to an undercarriage wheel disassembling and assembling device which comprises a three-jaw chuck, a flange plate, a sliding frame, an alignment lead screw, a two-way manual pump and the like. When the front landing gear wheel dismounting device reaches the position near the aircraft wheel needing to be dismounted, the alignment contact head extends out of the center shaft of the three-jaw chuck, and the alignment contact head is inserted into the axle of the front landing gear wheel after the height of the alignment contact head is adjusted to be consistent with that of the axle hole of the front landing gear wheel through the two-way manual pump; the frame assembly is provided with three traction trundles, and each trundle can independently rotate, so that the airplane wheel lifting device is accurately and quickly aligned with an airplane wheel tire needing to be disassembled before disassembly; the two-way manual pump extends after being pressurized to drive the three-jaw chuck assembly, and therefore the nose landing gear airplane wheel is disengaged from the nose landing gear airplane wheel shaft. The device is practical and novel, and overcomes the defects of low efficiency, inconvenience in disassembly and assembly, poor safety and the like of a traditional method for disassembling and assembling the nose landing gear wheel.
本发明属于航空技术领域,涉及一种拆装起落架机轮装置,包括三爪卡盘、法兰盘、滑架、对正丝杠、双向手动泵等。当拆卸前起机轮装置到达需要拆卸机轮附近位置后,对正接触头从三爪卡盘中心轴中伸出,用双向手动泵调整对正接头高度与前起机轮轴孔保持一致后,插入前起落架机轮轮轴中;车架组件装配有3个牵引脚轮,每个脚轮都可以独立转动方向,使得拆卸前起机轮装置准确、快速对正需要拆卸的机轮轮胎;双向手动泵加压后伸长,带动三爪卡盘组件,从而将前起落架机轮从前起落架机轮轴上脱出。本装置实用、新颖克服了传统拆装前起落架机轮方法效率不高、拆装不便、安全性欠佳等缺点。
