摘　　要：作为飞机螺旋桨重要的承力零件,桨根推力轴承在提供桨叶转动功能的同时,还承担了重要的受力角色。其故障会对飞机的运行安全造成严重隐患。本文通过对推力轴承座的冲击失效进行研究,分析其失效特征,深入研究故障机理,对螺旋桨厂家的检查标准进行优化,并总结出一套安全可行的维修建议。As an important load-carrying part of aircraft propeller,propeller thrust bearing not only provides the function of blade rotation,but also plays an important role in bearing force.Its failure will cause serious hidden danger to the safety of aircraft operation.This paper studies the impact failure of thrust bearing seat,analyzes its failure characteristics,deeply studies the failure mechanism,optimizes the inspection criteria of propeller manufacturers,and provides safe and feasible maintenance suggestions.
