采煤机在工作过程中,机器的零件在工作中要相互摩擦、磨损,加之其恶劣工作环境中的磨粒,特别是煤粉尘,加剧了零件表面的刮伤和磨损,加快了零件的失效。针对这一类型的损伤现象,提出了电刷镀技术修复方法,分析了其工艺过程。这样做,可以达到恢复尺寸,改善摩擦表面,延长零件寿命的目的。 Shearer in the work process, the parts of the machine in the work to be mutual friction, wear and tear, coupled with its harsh working conditions of abrasive particles, especially coal dust, exacerbated the parts surface scratches and wear and accelerate the failure of parts . Aiming at this type of damage, a method of repairing the brush plating is proposed and its process is analyzed. In doing so, you can achieve the resumption of size, improve the friction surface, to extend the life of parts purposes.
