中央传动锥齿轮共振破坏的实验研究
BEVEL GEAR RESONANCE FAILURES IN CENTRAL GEARING SYSTEM OF AN AEROENGINE
-
摘要: 本文通过某型机的排故实践,总结了航空发动机中央传动锥齿轮共振破坏的特征,失效模式和结构动力特性;分析了共振激发因素;提出了排故措施;指出了这类齿轮动强度设计今后应遵循的几个基本准则。Abstract: The resonance failures of the bevel gear in the central gearing system of an specific aeroengine have been investigated experimentally. The features of the resonance failures, the failure modes and structural dynamic characteristics are summarized, and the reasons for resonance are clarified. Some preventive measures against the failures are suggested and criteria for the dynamic strength design of this type of gear are specified.
