运转设备对中找正及其计算方法

Equipment Alignment in Operation and Its Calculation Method

大型运转设备运行前都必须对联轴器进行对中找正,对中找正不合格的设备运行时,联轴器处会产生很大的应力,机器振动异常,严重影响轴承(轴瓦)和轴上其他零件的正常工作,设备不能长周期稳定运行。基于此详细介绍了找正表架和百分表(或千分表)法对中找正的计算方法及调整方法。

Before the operation,the coupler of large equipment must be in alignment so as to reduce stress there.The abnormal vibration can influence the bearing（bearing brush） and the regular work of the shaft＇s parts and the long-term stable operation of the equipment.The calculation and adjustment methods from both alignment table frame and dial indicator（or dial gauge） were expounded.
