某发动机返厂后分解检查,先后发现多台发动机高压前轴颈锁簧槽单侧磨损问题。该问题的发生,不仅影响发动机正常生产进度,严重的还会危及外场飞行安全。通过对高压前轴颈锁簧槽装配原理、设计尺寸对比、装配间隙计算等方面进行深入分析,并且提出了一些有针对性的改进和控制措施,以期从本质上彻底排除该类故障,确保外场使用安全。
After the engine back to the factory decomposition inspection, has found more than one engine high pressure front axle lock spring groove unilateral wear problems. The occurrence of this problem not only affects the normal progress of engine production, but also seriously endangers the flight safety in the field. Through in-depth analysis on the assembly principle, design dimension comparison, assembly clearance calculation and other aspects of the high-pressure front journal lock spring groove, and some targeted improvements and control measures, in the hope of thoroughly eliminating such failures in essence, to ensure that the external field Use safe.
