高速列车轴承和齿轮的润滑

Lubrication of High - speed Train Bearing and Gear

良好的润滑是高速列车安全运行的基本保证,介绍了高速列车轴承和牵引齿轮的润滑情况和润滑剂。随着列车速度的提高,轴承和牵引齿轮的负荷和温度也升高,要求轴承和牵引齿轮润滑剂的性能不断提高,甚至必须使用合成润滑剂才能满足润滑要求。国外在这方面已做了大量的工作,值得我们借鉴。

Good lubrication is the basic guarantee of high - speed train secure operation, the lubrication conditions and the lubricants of bearing and traction gear of high - speed train are introduced. The load and temperature of bearing and traction gear promote along with the train speed elevates, the performances of lubricants to bearing and traction gear are asked to upgrade continuously, even synthetic lubricants must be used to satisfy lubrication requirement. And plenty of work has been done in this respect abroad, which is worth referring for us.
