摘　　要：通过对某型和谐号动车组齿轮箱轴承故障原因及结构机理分析,针对特定工况下齿轮箱轴承润滑不良问题制定了齿轮箱结构优化方案,从而提升齿轮箱的受油量,降低轴承干磨的概率。同时该方案通过了台架试验、模拟仿真、型式试验等一系列的试验验证,证明在保证原有结构可靠性基础上,对于改善轴承润滑不良的问题效果明显,现方案已经进入批量改造实施阶段,改造完成后动车组经跟踪应用效果良好。Through the analysis of the cause and structural mechanism of the gearbox bearing failure of a certain type of high-speed EMU,the gearbox structure optimization scheme was formulated for the poor lubrication of the gearbox bearing under specific working conditions,so as to improve the oil absorption of the gearbox and reduce the probability of dry grinding of the bearing.At the same time,the scheme has passed a series of tests such as bench test,simulation and type test,which proves that on the basis of ensuring the reliability of the original structure,it has obvious effect on improving the problem of poor bearing lubrication.
