本文讨论了电化学齿端圆弧修形中金属蚀除厚度变化与电流密度分布规律之间的关系；对电化学齿端修形齿轮进行了测量，齿端修形量和修形长度都随电流的增大而线性增大，修形区域过渡圆滑，修形齿轮对称性好。 In this paper, the relationship between the thickness of metal erosion and the distribution of current density is discussed. The tooth profiled gear is measured, Increasing the current linearly increases, the smooth transition region repair, repair gear symmetry.
