轨道交通用齿轮箱圆柱滚子轴承减摩技术研究

Research on anti-friction technology of cylindrical roller bearings in gearbox for rail transit vehicles

对于轨道交通车辆来说,轴承寿命不再是轴承疲劳失效的主要因素,温升和报警已经成为影响列车运行安全的主要因素,通过对圆柱滚子接触的工作表面进行减摩设计,降低轴承温升,提高列车安全运行的可靠性。

For rail transit vehicles,bearing life is no longer the main factor of bearing fatigue failure,and temperature rise and alarms have become the main factors affecting train operation safety.The anti-friction design of the working surface contacted by cylindrical rollers reduces the bearing temperature rise and improve the reliability of train operation safety.
