在过去二十五年或更长的时间内对于消灭热轴的课题谈了如此之多,应如何改进铁路车辆滑动轴承的性能,则不易达到目的。因此,本文企图考虑这个问题,并对新造车、重造车与修理后车辆的滑动轴承创造一条途径使在现有改进方法上有较好的性能。下表所示系美国铁路由于减少货车热轴甩车数而每年所得的节省。 So much has been talked about in the past twenty-five years or so about the issue of eliminating the hot shaft and how to improve the performance of railway vehicle sliding bearings is not easy to achieve. Therefore, this article attempts to consider this issue and to create a way for new, rebuilt and repaired vehicles’ sliding bearings to provide better performance on existing improvements. The table below shows the annual savings for the U.S. railways as a result of reducing the number of truck hotspots dropped.
