笔者于1989年有机会附带实地观察并了解到一些苏联铁路车辆用空心轴的生产及试验运用情况。苏联在七十年代后期有两家钢铁厂曾各自试生产了一批铁路车辆用空心轴。一家是德聂伯捷尔任斯基钢铁厂,该厂有一个专门轧制车轴的车间,于1978年采用纵向螺旋轧制法,轧制了一批共300根空心车轴,其内径尺寸为:两端轴颈部分均为42mm,轴身为90mm。其生产 In 1989, I had the opportunity to observe and understand the production and experimental use of hollow shafts for some Soviet railway vehicles. In the late 1970s, two steel mills in the Soviet Union tried to produce a number of hollow shafts for railway vehicles. One is the Dnepropetrovsk plant, which has a workshop dedicated to rolling axles. In 1978, a series of 300 hollow axles were rolled using a longitudinal helical rolling method, with inner diameters of two ends The journal part is 42mm, shaft body is 90mm. Its production
