摘要
建立加工中心丝杆轴承Weibull寿命分布模型,并利用其寿命分布模型给出轴承最佳周期维修策略,该策略能够应用于轴承等耗损型零部件。对周期模型进行了数学推导,同时也证明了周期维修策略不适用于早期和偶然失效型零部件。
The Weibull life distribution model of screw bearings in CNC center was built, with which an optimal periodic mainte- nance strategy for bearings was proposed subsequently. This strategy could be applied to. wear type components including bearings. Mathematical induction also shows that this periodic model is not suitable for early and random failure type components.
