摘要
通过FMEA分析方法,对电主轴的冷却系统进行设计,并对工艺过程潜在失效模式和后果进行分析,得出影响冷却系统可靠性的关键因素为冷却结构内表面磨削质量,对此潜在的风险从控制预防及控制探测两方面采取预防控制措施,初步验证生产过程试漏工序合格率由82%提高至96%。FMEA可靠性分析方法为电主轴其他系统功能可靠性的设计提供了参考,对电主轴整体可靠性设计的提高具有重大意义。
Through FMEA analysis,the cooling system of the spindle was designed,and the potential failure modes and consequences of theprocess were analyzed.The key factors affecting the reliability of the cooling system were the grinding quality of the inner surface of the coolingstructure.The prevention and control measures were taken for this potential risk from two aspects of control prevention and control detection.The qualified rate of the leak test procedure in the production process was improved from 82% to 96%.FMEA reliability analysis methodprovides reference for the design of other system function reliability of spindle,and it is of reference significance to improve the overallreliability design of spindle.
