由烏拉尔和西伯利亚铁路干綫貨运工作情况表明,使用滑动軸承的軸箱部件是不可靠的,因为它降低了电气和內燃牵引的效果。例如,每辆因热軸和軸頸划伤而甩車的車辆,其平均行走公里为85万軸·公里,而在个別月份甚至低至45万軸·公里。因此,我們曾在貨运量最大的干綫上进行了試驗,探求 The work carried out by freight routes on the Urals and the Trans-Siberian railways shows that the use of journal bearing components of the bearings is not reliable as it reduces the effects of electrical and internal combustion traction. For example, each vehicle that has been dropped due to scratches on hot shafts and journals has an average of 850,000 kilometers per kilometer traveled in kilometers and even as low as 450,000 kilometers per kilometer in individual months. Therefore, we conducted tests on the trunk lines with the largest volume of freight and explored them
