目前,国内外小功率柴油机已广泛采用球铁曲轴,而在大功率高速柴油机上一般仍采用合金钢锻造曲轴.我国四方机车车辆厂生产的“东方红”内燃机车12V 175E大功率高速柴油机设计功率为1000马力,转速1500转/分,曲轴原设计为42CrMo合金钢纤维挤压曲轴.遵照伟大领袖毛主席关于“打破洋框框,走自己工业发展道路”、“备战、备荒、为人民”的教导,我们于1966年开始进行12V175E大功率高速柴油机球铁曲轴的试制工作,在战无不胜的毛泽东思想指引下,试制出了一批球铁曲轴,并进行了装车运行试验,经走行30多万
At present, the domestic and foreign low-power diesel engines have been widely used ductile iron crankshaft, and high-power high-speed diesel engines are still generally used forged steel crankshaft.China Sifang Locomotive Works produced “Dongfanghong” diesel locomotive 12V 175E high-power high-speed diesel engine design power 1000 horsepower, speed of 1500 rev / min, the original design of the crankshaft 42CrMo alloy steel fiber extrusion crankshaft.According to the great leader Chairman Mao on “breaking the ocean frame, take the road of industrial development,” “prepare for the shortage, for the people” teaching , We started the trial production of 12V175E high-power high-speed diesel ductile iron crankshaft in 1966. Under the guidance of invincible Mao Zedong Thought, we made a batch of ductile iron crankshafts and carried out the loading running test. After running more than 30 Million
