大型水轮机主轴车削加工质量关键点控制

Turning Quality Control of Main Shaft in a Large Hydraulic Turbine

大型水轮机主轴是水轮发电机组关键部件,与转轮、水导轴承、发电机主轴等零部件紧密配合。良好的加工质量是保证轴系优良的摆度值及较小振动的前提,可确保机组长期稳定运行。文中从公司设备资源、主轴结构及制造技术角度出发,介绍了大型水轮机主轴车削加工质量关键点及控制措施,可为类似大型水轮机主轴加工提供借鉴与参考。

The main shaft is a key component of a large hydro-generator unit,and it is closely matched with the runner,the water guide bearing,and the main shaft of the generator.Good machining quality can ensure the excellent swing value and small vibration of the shaft system,which can ensure the long-term stable operation of the unit.According to equipment resources,spindle structure and manufacturing technology,the key points and control measures of turning quality of the main shaft of a large hydraulic turbine are introduced,which can provide reference and reference for the main shaft processing of similar large hydraulic turbines.
