用滚动轴承式抱轴承来取代现有机车上的滑动轴承式抱轴瓦 ,这是俄罗斯铁路机车现代化改造中的迫切任务之一。文内对 196 3～ 196 5年间开始的这次现代化改造工作未取得成功的原因作了分析 ,并针对现有内燃机车和电力机车给出了两种滚动轴承式抱轴承的牵引电动机 轮对组件的结构及其试验结果。试验表明 ,装用滚动轴承式抱轴承后 ,内燃机车可节约柴油 5 %～ 6 % ,电力机车至少可节约电能 4% The use of rolling bearing bearing to replace the existing locomotive bearing bearing axle, which is the modernization of the Russian railway locomotive one of the urgent tasks. The article analyzes the reasons for the failure of the modernization that started in 1953-1956 and gives two types of traction motor wheelsets for rolling stock and electric locomotive for existing diesel locomotives and electric locomotives Structure and test results. Tests show that with roller bearing bearings installed, the diesel locomotive can save 5% to 6% diesel, electric locomotive can save at least 4%
