摘要
大型机械的主轴在使用过程中可能出现轴颈磨损,轴承出现所谓的"跑内沿"现象,给设备的安全运行带来很大隐患。目前修复的方法较多,但施工难度、费用、工期、可操作性等方面差异很大。实践证明,采用冷焊处理方法,工艺简单、费用低、达到了主轴修复的目的。
The crankshaft journal of the large machine spindle may worn during the operation. The ＂running around the inside＂ phenomenon may occur of the bearings, which leads to accident. Currently, there are lots of repair methods, but the construction difficult, cost, work period and the operation are different. According to practice, adopts the cold welding process method, the technical of which is simple, the cost is low and achieves the aim of spindle repair, spindle of large machine may worn crankshaft journal during the operation.
