发动机凸轮轴的维修

Maintenance of Engine Cam Axis

刷镀在零件表面磨损修复中具有很好的适应性和灵活性,表面修复方便快捷。堆焊则可以利用焊材与母材的熔合进行较大的表面缺陷修复。将两者结合起来修复一些轴类零件不仅会带来更好的修复效果,还具有较好的经济性。本文以发动机凸轮轴为例,详细说明了刷镀与堆焊相结合进行综合修理的工艺过程。

Brush electroplating and built-up welding are the repair technique which are normally used on the parts due to abrasion or partial failure. Brush electroplating has good adaptability and flexibility in the parts surface maintenance,and can repair the surface quickly and easily. Built-up welding can be used in the large areas surface defects repair with the welding materials and the parent metal fusion. Combination of the two kinds of repair technique can obtain the better repair effects,and also generates significant economic benefit in repairing the parts like axis. Based on the comprehensive repair of the engine cam axis,a detailed description of integration of the brush electroplating and built-up welding and their repair process are introduced in this paper.
