一、绪论 1965年10月,利用在东北干线实行交流电气化的机会,在本段使用了ED75型电力机车。现已有普通型18台,高速型30台共48台机车承担着繁重的运输任务。本段自电力机车投入运行以来,作为电力机车心脏部分的牵引电动机不断出现故障,成了关键问题。而且这个问题不仅是本段的,也是全国性的大问题,迫切需要查明原因,找出对策,为此,於1968年11月成立了牵引电动机管理组。为查明故障原因和研究对策,我们对过去的牵引电动机进行了种种分析研究,结果查明,由驱动装置产生的振动是牵引电动机产生故障的主要原因之一。如果能够控制它的振动就能大大减少牵引电动机的故障。
I. INTRODUCTION In October 1965, the ED75 electric locomotive was used in this paragraph by taking advantage of the opportunity of AC electrification in the Northeast Main Line. Now there are 18 ordinary type, 30 high-speed type a total of 48 locomotives undertake heavy transport tasks. This paragraph has been the key issue since the electric locomotive put into operation, as the heart of electric locomotive traction motor failure. And this issue is not only this paragraph, but also a national big problem, there is an urgent need to identify the cause, identify the countermeasures, for which, in 1968 November set up traction motor management group. In order to find out the cause of the malfunction and the countermeasures, we have carried on various kinds of analysis and research to the past traction motor. The result shows that the vibration caused by the driving device is one of the main causes of the traction motor failure. If you can control its vibration can greatly reduce traction motor failure.
