The invention discloses an airplane wheel hub, an airplane wheel and an airplane. The nipple-shaped structure is arranged on the butt joint face of at least one of the inner half hub and the outer half hub of the airplane wheel hub, the bending resistance of the hub radial plate can be improved, the stress of the radial plate and a bolt hole is reduced, the nipple-shaped structure is simple in forming process and free of complex milling, the service life of an airplane wheel is prolonged, the reliability of the airplane wheel is improved, and meanwhile the cost is low. The sealing ring groove on the inner half hub and the rim are in transition connection through a smooth transition structure, stress concentration at the sealing ring groove can be reduced, the sealing ring installation guide cone is further arranged at the outer half hub, the phenomenon that the sealing ring is twisted when the airplane wheel is installed can be avoided, and maintainability of the airplane wheel is improved. Through detailed design, the airplane wheel hub can meet the design requirements of light weight, long service life, high reliability, good maintainability, low cost and the like on the basis of meeting the basic technical requirements, and the problems existing in the prior art are solved.

    本发明公开一种机轮轮毂、飞机机轮和飞机。机轮轮毂的内半轮毂和外半轮毂中至少一者的对接面上设置奶嘴状结构,可提高轮毂辐板抗弯能力,降低辐板及螺栓孔应力,且奶嘴状结构成型工艺简单,无复杂的铣削加工,在提高了机轮寿命和可靠性的同时成本较低。内半轮毂上密封圈沟槽和轮辋之间采用圆滑过渡结构过渡连接,可减小密封圈沟槽处的应力集中,外半轮毂处还设置有密封圈安装导向锥,可避免机轮安装时密封圈发生扭曲现象,提高了机轮维修性。上述机轮轮毂通过细节设计,可在满足基本技术要求的基础上,还满足重量轻、寿命长、可靠性高、维修性好、成本低等设计要求,克服了现有技术存在的问题。
