曲軸的制造,有鑄造和锻造二种。鑄造曲轴在国內还比較少,但在國外很早就生產应用。事实上,早在58年前,亦卽在動力机械製造工業發展的初期就已有用鑄铁曲軸了。如在1934年9月,美國金属协会在紐約举办的展览会中,便有一根使用在礦山机械中的鑄铁曲軸。这根曲軸造於1898年,至展览時已安全的运用了36年,它是以加大曲軸的尺寸製造应用的。从文獻上看,英國在1935年也已開始生产孕育鑄铁的曲軸了。近來最大的曲軸已用到2400馬力的柴油机上,主軸頸的直徑达254公厘。苏联和民主德國在这方面的工作也有很大成绩和進展。如苏联的俄罗斯柴油机厂以鑄造的球墨
The crankshaft is manufactured by casting and forging. Casting crankshaft is still relatively small in China, but it is produced and applied very early in foreign countries. In fact, as early as 58 years ago, the cast iron crankshaft was used in the early stage of the development of the power machinery manufacturing industry. As in September 1934, the American Metal Association’s exhibition in New York had a cast iron crankshaft used in mining machinery. This crankshaft was built in 1898 and has been safely used for 36 years at the exhibition. It is manufactured by increasing the size of the crankshaft. From the literature point of view, the United Kingdom also began production of cast iron crankshafts in 1935. The largest crankshaft has recently been used on a 2400-horsepower diesel engine. The main journal has a diameter of 254 mm. The work of the Soviet Union and Democrats in this area has also achieved great results and progress. Such as Soviet Union’s Russian diesel plant to cast ball ink
