摘要
数控机床主轴系统是数控机床的关键子系统,其故障较多,而每次故障现象又比较单一,因此,单纯通过故障现象往往不能作为故障诊断和排除的依据。应用FMECA分析方法,分析数控机床主轴系统各组成部分的故障模式及故障原因,并进一步计算各组成部分的危害程度,得到的危害程度为制定设备维修策略提供了参考。
The spindle system is the key subsystem of CNC machine tools, it has lots of failure and has compari- son of a single failure phenomenon. Therefore, failure phenomenon often cannot be used to failure diagnosis and troubleshooting. In this paper, FMECA analysis methods was used, to determine the failure mode and causes of the components of the spindle system of CNC machine tools, and further calculate the damage degree of each component. Finally, the damage degree provides the reference for equipment repair strategy.
