| 航空轴承是航空发动机的核心部件之一，具有高温、高速、载荷大、受力复杂、工作环境苛刻等特点。从理论上说，目前提高航空发动机推力和燃油效率的最直接方法依然是提高涡轮进口温度和转子转速，而提高转速对航空轴承的极限转速性能、耐温能力、润滑性能和承载能力均提出了更加严峻的要求。 Aviation bearing is one of the core components of aeroengine. It has the characteristics of high temperature, high speed, large load, complex force and harsh working environment. In theory, the most direct way to improve thrust and fuel efficiency of aero-engine is still to increase the inlet temperature of turbine and rotor speed. Increasing the speed requires more stringent performance of aero-bearing in limiting speed, temperature resistance, lubrication and load-carrying capacity. 我国的轴承工业虽经过多年快速发展，目前已成为轴承产量和销售金额位居世界第3的轴承大国，但是关键技术领域还有待加强，特别是航空轴承技术与世界轴承强国相比差距比较明显，不能满足我国航空装备型号迅猛发展和性能大幅提升的要求。 After years of rapid development, China's bearing industry has become the third largest bearing country in the world in terms of output and sales volume, but the key technical fields need to be strengthened, especially the gap between aviation bearing technology and the world's powerful bearing countries is obvious, which can not meet the rapid development and performance of China's aviation equipment types. Requirements that can be substantially upgraded. |
