内燃机车在线路上运行时发生牵引电机小齿轮松缓、大齿轮崩齿甚至牵引电机断轴后将对机车电机等关键部件造成破坏,从而引发特大行车事故。分析了牵引电机齿轮故障的原理,根据牵引电机齿轮所处的特殊位置,研制了一种新型的机车牵引电机齿轮故障监控报警装置,正确判断电机齿轮故障,及时提醒乘务员,保证机车安全行驶。
When the diesel locomotive running on the line, the pinion of the traction motor is loosened, and the broken gear of the big gear or even the broken shaft of the traction motor will cause damage to the key components of the locomotive motor and the like, thereby causing a special traffic accident. Based on the special position of traction motor gear, a new type of monitoring and warning device for gear fault of locomotive traction motor was developed to correctly judge the gear failure of the motor and promptly notify the flight attendants to ensure the safe running of the locomotive.
