According to the split type hub sealing structure for the aviation aircraft wheel and the design method of the split type hub sealing structure, the space of a closed containing cavity formed by the split type hub sealing structure is smaller than that of a rectangular structure, and an arc sealing face with the same radius as the section of a sealing ring is designed at the bottom of the cavity; the contact area of the sealing ring and the sealing surface of the sealing cavity is increased, and the sealing ring is not easy to fall off. According to the technical scheme, when the two half hubs are connected through bolts, the sealing structure can be used for sealing high-pressure gas in an aviation aircraft wheel tire, it is verified through tests that the sealing gas pressure can be increased to 13 MPa from original 8 MPa, and the sealing structure has guiding significance on aviation aircraft wheel hub sealing design.

    用于航空机轮的对开式轮毂密封结构及其设计方法,提出的对开式轮毂密封结构形成的密闭容腔,空间相比矩形结构小,并且腔底设计有与密封圈截面半径相同的圆弧密封面,密封腔安装密封圈后,增加了密封圈与密封腔密封面的接触面积,不容易使密封圈脱出。采用本发明的技术方案,当两半式轮毂采用螺栓连接时使用该密封结构可以密封航空机轮轮胎中的高压气体,经试验验证密封气压可由原来的8MPa提升至13MPa,并且对航空机轮轮毂密封设计具有指导意义。
