传动中心快速找正──同步法

Synch Method to Fast Align Driving Center

以N3──Z4型3000KW汽轮机组检修过程为实例，介绍只用百分表就能进行汽轮机主轴与减速器小齿轮轴、减速器大齿轮轴与发电机主轴间联接的中心找正调整方法。这种传动中心的测量调整过程称为同步法。通过实践证明，用同步法进行调整后的机组，系统传动精度是确保的，消除了机组原来存在的问题，设备运行正常，经济效益明显地提高。

On basis of oxamination & repair of a N3-24 3.000kWsteam turbine set ,is introduced a way to align and regulate by percentage the connection of the steam shaft ,and of the box's big gear -shall with the generator s major shaft ,Such a way to mcasure and regulate the drive centerline is called synch method. It is proved in practice that the the driving precision is high .the equipment work better ,and the economic benefit raises more notably when the sct being regulated so
