摘　　要：轴承寿命内失去其应有的使用性能,导致故障或不能正常工作的现象,称轴承失效．轴承的失效分为两类,止转失效和丧精失效。航空发动机轴承的失效模式主要有,滚动接触失效、开裂和断裂失效、旋转爬行失效、轴承磨损失效、塑性变形失效、微动磨损失效等。分析研究轴承的失效模式目的是为制定预防失效措施提供理论依据。Losing its use capability in the life-span of the axletree, it causes the phenomenon of faults or work abnormally, that called axletree failure. The failure is divided into two kinds, they are stop rotating failure and losing extract failure. The main failure modes of the aero-engine axletree are rolling and contacting failure, fracture and rupture failure, rotating and creeping fail- ure, axletree abrasion failure, plasticity distortion failure, jiggle abrasion and so on. The purpose to research the failure mode of the aero-engine axletree is offering the theoretical foundation for making and preventing the invalid measure.
