In this, can use repair drive shaft and bushing method to recover its normal fitclearance.
遇此，可采用修主动轴或衬套的方法恢复其正常的配合间隙。

If the drive shaft wear mild, just press the old bush changed after standard size bushing, fitclearance can be restored to allow range.
若主动轴磨损轻微，只需压出旧衬套后换上标准尺寸的衬套，配合间隙便可恢复到允许范围。

This paper describes the structural design of a vertical shafting, analyses and calculates the wobble error and fitclearance in the developed ballistic camera.
