摘要
在采煤机作业过程中,截齿是使用量最大最容易损坏的零部件之一。截齿失效会对煤炭开采带来很大的影响。因此,本文对采煤机截齿风险评价进行了研究,通过FMEA评价方法,分析了截齿的主要故障模式,并进行了定量计算。结合分析结果和现场实践,提出了延长采煤机截齿寿命的对策。
In the mining machine operation process, the cutting tooth is one of the most easily damaged parts. The failure of cutting tooth will bring great influence on coal mining. Therefore, this paper studied the risk assessment of shearer cutting tooth, analyzed the main fault mode of cutting tooth through FMEA evaluation method, and carried out quantitative calculation. Based on the analysis results and field practice, the measures to prolong the life of shearer cutter are put forward.
