摘　　要：针对航空发动机机械系统具有专业技术复杂,故障多发等特点,通过对国内外航空发动机机械系统的技术分析,阐述了传动、润滑、密封和主轴轴承4个专业的技术水平现状及未来技术发展趋势,并归纳总结了目前国内、外在航空发动机机械系统研制过程中的常规做法。认为提高从业人员技术能力,完善专业设计规范和提升机械系统技术水平是当务之急。从业人员应关注设计细节,注重经验积累,用数据说话,重视基础研究工作;同时建议积极开展国际技术合作,加强航空发动机机械系统专业技术交流。Aiming at characteristics of complicated technology and multiple failure for aeroengine mechanical system, the status and future development trends of four professional technologies including transmission, lubrication, sealing and bearing were illustrated by analyzing the aeroengine mechanical system technology in the world, and conventional method in the development process of the aeroengine mechanical system in the West was concluded and summarized. All in all, the urgent thing is improving the design capability, perfecting the technical design specifications and promoting the mechanical technology levels now. Practitioners should pay attention to detailed design, experience and data accumulation, and basic the fundamental research. Meanwhile,it is a good advice to develop the technological exchange and cooperation of the aeroengine mechanical system in the world.
