我公司许多大零件需要进行静平衡校正，为此需设计制造很多平衡轴，大大增加了制造成本。为了节约费用，我们对常规设计进行了改进，现介绍如下：１常规设计方法如图所示静平衡校正结构中，以前没有连接圈６，而是用定位圈４直接与轴档　ｄ１过盈配合，这样只能使用一次，下次 Many large parts of our company need to be static balance correction, this need to design and manufacture a lot of balance shaft, greatly increased manufacturing costs. In order to save costs, we have improved the conventional design, are introduced as follows: 1 Conventional design method As shown in the static balance correction structure, there is no previous connection ring 6, but the positioning ring 4 directly with the shaft d1 interference fit , This can only be used once, next time
