摘要:
转向架齿轮箱为地铁车辆传动系统的重要部件，若其零部件发生非正常磨损，产生的金属粉末进入润滑油中循环，会导致齿轮齿面产生磨粒磨损、疲劳凹坑等问题，也会加剧轴承磨损导致运转不良等情况。分析了转向架齿轮箱分油环异常磨耗原因，验证了齿轮箱输入轴系装配工艺，对输入轴端盖压紧量进行了建模计算，查明了分油环非正常磨损的原因。在此基础上提出了相应的优化改进措施，有效解决了转向架齿轮箱分油环异常磨耗问题。
Abstracts:
Bogie gearbox is an important part of metro vehicle transmission system. If its parts are abnormally worn and the generated metal powder enters into the lubrication oil circulation, it will lead to problems such as abrasive wear and fatigue pit on the gear tooth surface, and will also aggravate the bearing wear leading to poor operation. The causes of abnormal wear of oil distribution ring of bogie gearbox are analyzed. The assembly process of gearbox input shaft system is verified. The compression amount of input shaft end cover is modeled and calculated, and the causes of abnormal wear of oil distribution ring are discovered. On this basis, the corresponding optimization and improvement measures are put forward, which effectively solves the problem of abnormal wear of oil distribution ring of bogie gearbox.
