In designing chain drive is applied other than using worm wheel drive as the imported equipment does. Using two-end bearing support will greatly increase the thickener's running cycle.

用制造和安装精度要求不高的链传动取代了原进口设备采用的蜗轮蜗杆传动，采用双端支承方式和滚动轴承，有效地提高了设备的运行周期。

Besides, at the non-drive-end of the primary shaft, 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。
