For the drive shaft balancing machine, the hard bearing can achieve the accuracy is far beyond the actual needs.

对于传动轴平衡机来说，硬支承所能达到的精度也远远超出了实际需要。

If it is found that the accuracy of a drive shaft balancing machine can not meet the requirements, it must be the result of other factors.

如果发现一台传动轴平衡机的精度不能满足要求，那一定是其它因素造成的结果。

And the main influencing factors are two, 1, the transmission shaft and the balance machine connection way. 2, balancing machine spindle processing accuracy.

而主要影响因素有两项，1、传动轴与平衡机的联接方式。2、平衡机主轴加工精度。
