However, during the matching test of the main shaft performance test and during operation, since the small hole restrictor that plays a throttling role is placed inside the bearing, when the restrictor needs to be replaced, the main shaft needs to be assembled and disassembled, which brings inconvenience. In addition, multiple assembly and disassembly of the main shaft will reduce the dynamic balance accuracy of the main shaft and affect the rotation accuracy of the main shaft. Therefore, in order to facilitate the replacement of the small hole restrictor, a simple device for installing and disassembling the small hole restrictor is needed.
