摘　　要：转轴失效是指转轴在使用中因某种原因不能完成设计功能或断裂。断裂失效往往会引起灾难性的飞行事故。转轴的失效模式主要有疲劳失效、磨损失效、腐蚀失效、变形失效等。文章对此进行了详细的分析叙述,为判断转轴的失效提供了理论依据。The failure of revoling axle is that revoling axle can＇t finish plan function or rupture when it is used. ruptured and failed causes catastrophic flight accidents. The failure modes of revoling axle are fatigue failure, abrasion failure, corrode failure, deformed failure and so on. This paper offers the theoretical foundation for judging the failure of revolving axle.
