摘　　要：高速动车组齿轮箱的润滑是高速列车运行安全的关键技术之一。为了研究高速动车组在用齿轮油的衰变特性,指导现场定置换油,提出了高速动车组齿轮油换油周期方法。通过在京沪专线动车组上选取CRH6444车6部齿轮箱在用油连续9次的跟踪监测,采用理化指标评估法、污染变化评估法、添加剂消耗评估法、磨损情况评估法对CRH动车组齿轮箱在用润滑油的换油周期进行了评估。研究结果表明,高速动车组齿轮箱在用的车辆齿轮油平均换油周期里程不超过35万公里为宜。研究结果可以为我国CRH动车组齿轮箱检修和安全运行提供在用润滑油更换技术参考。Lubrication of high speed electric multiple unit （EMU） gear box is one of the key technologies of high speed train operation safety. Drain interval method of gear oils was proposed on the high speed EMU in order to study the decay characteristics for used gear oil and guide changing oil on site. In the test,6 Gearboxes of CRH6444 compartment on the Beijing-Shanghai line were monitored for 9 times, and the oil drain interval was estimated by four measures, physical and chemical properties evaluation method, contaminated properties evaluation method, additives consumption evaluation meth- ods and wear characteristics evaluation method. The results show that it is appropriate for the used gear oil drain interval of high speed EMU gearbox with no more than 350 000 km on average. The research results provide technical reference for the high speed train-set gearbox maintenance and safe operation in China.
