掘进机截齿失效形式与对策分析

Pickers’ failure form of roadheader and analysis of countermeasure

为了更好的进行掘进机可靠性研究,为掘进机设计提供的依据,通过对掘进机截齿的失效形式的分析,得出了截齿失效的主要原因,为开展截齿可靠性研究奠定了基础,只要解决截齿在设计、制造、选择和使用等方面存在的问题,就能够明显地提高截齿的可靠性,大大降低截齿损耗,很好地适应高产、高效矿井建设和发展的需要。

The major reason of the pickers＇ failure will be obtained according to the analysis of the pickers＇ failure forth of the roadheader in order to study the reliability of the roadheader well and support the foundation to the roadheader design. It can lay a foundation for the reliability of the roadheader reaserch .There are problems in picker＇s design, manufacturing, option and application. The reliability of the pickers will be improved and the pickers＇ deterioration will be reduced greatly by solving these problems. And then the roadheader can be adapted to the development and needs of high-yielding and efficient mine construction.
