摘　　要：滚动轴承作为航空发动机的关键部件,必须依靠高效润滑冷却技术保障其在高速、高温和重载的严苛工作环境下稳定运转。与传统喷射润滑相比,环下润滑技术具有诸多优势,已成为现代发动机主轴轴承的主流润滑方式。本文围绕航空发动机主轴轴承的高效润滑冷却技术,对比了典型润滑方式,系统梳理并总结了环下润滑技术的发展现状,讨论了环下润滑轴承的润滑冷却效果,对航空发动机主轴高速轴承润滑冷却技术的未来发展趋势进行了展望,为航空轴承高效润滑冷却和精细化热管理提供参考。Rolling bearings are the critical components of aircraft engines,which require the efficient lubrication and cooling technologies to ensure stable operation under the harsh conditions of high speed,high temperature,and heavy load.Compared to traditional jet lubrication,the under-race lubrication because of numerous advantages has become the mainstream lubrication method for modern engine main shaft bearings.According to the efficient lubrication and cooling technology for aircraft engine main shaft bearings,the typical lubrication methods are compared.The current development status of under-race lubrication technology is systematically reviewed and summarized,and the lubrication and cooling effects of under-race lubricated bearings are discussed.The future development trends in lubrication and cooling technology for high-speed bearings in aircraft engines are explored,which can provide the reference for efficient lubrication,cooling,and refined thermal management of aviation bearings.
