摘　　要：直升机减速器润滑系统出现故障,齿轮轴承将处于无润滑油工作状态,使减速器在短时间内破坏,造成灾难性的后果。对直升机减速器润滑系统提出多种应急方案:如选用耐高温材料;增加齿轮齿侧间隙;改进减速器内部结构;采用含抗磨剂的润滑剂进行油气润滑和油雾润滑和;增加液压应急润滑系统;采用固体润滑代替液体润滑;采用冷风冷却代替液体冷却。If the lubrication system of a helicopter reducer is compromised, its gears ann Deanngs wui ne at non-monca- ting oil work state,which will cause the reducer to be damaged in a very short time and result in disastrous consequences. Many kinds of emergency measures of helicopter reducer lubrication system were presented, such as using high temperature resistant materials, increasing the gear backlash ; improving the internal structures of helicopter reducer; adopting oil/air lu- brication and oil/mist lubrication with the lubricating oil containing anti-wear additives;increasing a hydraulic emergency lubrication system;using solid lubrication instead of liquid lubrication, cold air cooling instead of liquid cooling.
