摘　　要：在航空发动机等高速运转的机械中,保持架的断裂是轴承失效的重要原因之一,保持架的失效又和保持架的频率有关。对保持架的模态进行了分析,包括保持架兜孔数变化对轴承固有频率的影响,为避免保持架共振提供了理论依据,为高速轴承保持架的设计提供了参考。In high speed machinery such as aero-engine, the fracture of cage is one of the important reasons of bearing failure, and the failure of cage is related to the frequency of cage. In this paper, the modal of the cage is analyzed, including the effect of the change of the pocket number of the cage on the natural frequency of the bearing, which provides a theoretical basis for avoiding the cage resonance and provides a reference for the design of the high speed bearing cage.
