由于1995年美国CR6588机车牵引电动机电枢轴承严重损坏,曾造成货物列车脱轨事故。事故后分析结果表明,故障发生是由于电枢轴承润滑失效造成。通过对牵引电动机走行公里统计及轴承故障分析后得出结论:牵引电动机电枢轴承保守的使用寿命是80万km,低于这个数时出现的问题通常与不合适的安装、电气造成的伤损、腐蚀和电机与轴承过
As in 1995 the United States CR6588 locomotive traction motor armature bearings seriously damaged, had caused the goods train derailment accident. The analysis after the accident showed that the failure occurred due to the failure of the armature bearing lubrication. Through the traction motor running kilometer statistics and bearing fault analysis concluded that: Traction motor armature bearings conservative service life is 80 million km, below this number of problems are usually associated with improper installation, electrical damage , Corrosion and motor and bearing too
