曲轴是动力机械的重要零件。几年来,我们用焊接方法修复了几百根折断了的各种曲轴。修复后,使用情况良好。现将修复方法介绍如下,供大家参考。一、曲轴折断部位及焊接前的准备工作1.折断部位:曲轴折断部位经常发生在以下三处:1.由曲拐中部折断(图1);2.由曲拐与轴颈圆角处折断(图2);3.由轴颈圆角处折断(图3)。

Crankshaft is an important part of power machinery. In recent years, we have used welding methods to repair hundreds of broken crankshafts. After repair, the usage is good. The repair methods are introduced below, for your reference. First, the crankshaft broken parts and preparation before welding 1. Broken parts: crankshaft breaks often occur in the following three places: 1. Breaking from the middle of the crank (Figure 1); 2. Break from the crank and the journal fillets (Figure 2); 3 by the journal fillet broken (Figure 3).
