伟大领袖毛主席教导说:“中国人民有志气,有能力,一定要在不远的将来,赶上和超过世界先进水平.”我们的内燃机车牵引从动齿轮,原采用国外设计中的钢种45CrNi;1964年左右,铁道科学研究院与大连机车车辆工厂协作选用42CrMo钢代替了45CrNi钢,为国家节约了稀缺的元素镍.但是,铬仍是我国稀缺的元素,而且它的用途较广.为了把铬用于更重要的方面,并且利用我国所富有的合金资源,建立自己的齿轮用钢,自1966年开始,我们进行了以锰、钼、钒为基的中碳低合金钢调质新钢种的研究工作,以进一步取代42CrMo钢. 内燃机车牵引从动齿轮,是内燃机车上的
Great Leader Chairman Mao taught: “The Chinese people, with ambition and ability, must catch up with and surpass the world’s advanced level in the near future.” Our diesel locomotive traction driven gear originally used steel in foreign designs 45CrNi; around 1964, the Institute of Railway Research cooperated with Dalian Locomotive and Rolling Stock Works to replace 42CrMo steel with 45CrNi steel, saving the country a scarce element of nickel, however, chromium is still a scarce element in our country and its use is broader. In order to use chromium for more important aspects, and to utilize our rich alloy resources to build our own gear steel, we started with medium-carbon low-alloy steels based on manganese, molybdenum and vanadium since 1966 New types of steel research work to further replace the 42CrMo steel. Diesel locomotive traction driven gear, the diesel locomotive
