Improvement of Riveting Process for Impeller of Centrifugal Fan

针对铆钉与孔之间的间隙偏大,铆钉时的先后顺序不同而引起的叶轮轴向跳超标问题,通过改变间隙和铆铆钉的先后顺序改变了重心位置,解决了跳动超标的难题。

According to the larger clearance between rivet and hole and the problem of shaft runout of impeller over standard caused by the different sequence during riveting,it can be solved through changing the clearance and the sequence of rivet,and then changing the position of gravity center.
