摘 要： This study presents a combined preventive maintenance strategy for bearings to accomplish the failure prevention of rotating equipment. The concepts of preventive maintenance and trend chart are introduced in the beginning. Next, as an illustration, this strategy installs four accelerometers at selected locations of the equipment to acquire vibration amplitude data periodically. Only if any one of amplitudes exceeds the corresponding prescribed warning value, the acquired time-domain signal then is sent to the vibration analyzer to establish the corresponding frequency spectrum by the Fast Fourier Transform method. Contrasting the frequency of the highest amplitude among the amplitudes of harmonic frequencies in the spectrum with the calculated defect frequencies of the bearings, the defective bearing can be accurately located. Consequently, the abnormality of the defective bearing is early detected such that failure of the rotating equipment is prevented by executing preventive maintenance. At the end, the defective bearing is taken out from the monitored equipment to verify this investigation. The reliability improvement of rotating equipment is illustrated as well. This study was performed in a real workshop.

本研究提出了一种轴承综合预防性维护策略，以实现旋转设备的故障预防。首先介绍了预防性维护和趋势图的概念。随后，通过实例说明，该策略在设备选定位置安装四个加速度计，定期采集振动振幅数据。只有当任一振幅超过相应设定的预警值时，才将采集到的时间域信号发送至振动分析仪，并采用快速傅里叶变换法生成对应的频率谱。通过将频谱中谐波频率振幅最高的频率与轴承计算出的缺陷频率进行对比，即可准确确定存在缺陷的轴承位置。因此，缺陷轴承的异常可被早期发现，从而通过实施预防性维护避免旋转设备发生故障。最后，将出现故障的轴承从监控设备中取出，以验证上述检测方法。同时，也展示了旋转设备可靠性的提升效果。本研究是在一个真实的工作坊中进行的。[%$#@*]防错； 预防性维护； 频率谱； 轴承； 振动
