众所周知,曲轴是柴油机上最重要的部件之一。曲轴锻件毛坯的优劣又是决定曲轴质好坏的先决条件。在采用自由锻扭转方法制造大型柴油机曲轴毛坯中,锻造扭转变形量的大小对曲轴机械性能到底有多大影响?少量的反扭会不会严重影响曲轴的机械性能?现将这方面有关试验与结果简要的介绍如下。
As we all know, crankshaft is one of the most important parts of diesel engine. The pros and cons of crankshaft forgings is a prerequisite for determining the quality of crankshafts. In the free forging torsion method for manufacturing large diesel crankshaft rough, the amount of forging torsional deformation of the mechanical properties of crankshaft in the end how much? A small amount of anti-torsion will not seriously affect the mechanical properties of the crankshaft? Now in this regard the test and results A brief introduction is as follows.
