摘要
针对某型航空交流发电机轴承故障形貌特征,分别从结构参数、材料、润滑脂性能及填脂量等4个方面对轴承损坏的原因进行了排查和分析。结果表明,润滑不良是导致轴承失效的主要原因。通过采取相应的改进措施,取得了良好效果。
According to the fault characteristics of the bearing for a certain type of aviation AC generator, the reasons of the bearing damage are analyzed from four aspects, including the structural parameters, material, the performance and the filling amount of the grease. The results show that the bad lubrication is the main cause of the failure of the bearing, and good results have been achieved by taking the corresponding improvement measures.
