On the basis of the model, we found ways to release the primaryshaft vibration's influence on the quality of the polish surface.
在理论分析的基础上，提出减轻由主轴的振动引起的抛光表面质量问题的方法。

Besides, at the non-drive-end of the primaryshaft, some mechanical fitting in the bearing case were detected loosen, through spectrum-zoom analysis and waveform comparison in the time-domain.
另外，由转频附近细化谱分析及时域波形比较，发现输入轴非电机端轴承座内机件还有径向配合松动故障。

Think of it as a rotating transformer, with the primary windings residing in a stationary casing (stator) and the secondary conductors attached to an inner shaft (rotor).
