摘要

为了提高煤炭开采效率及采煤机的使用寿命,分析了截齿的失效形式及原因,阐述了截齿失效造成的影响,针对截齿在不同地质条件下的选择、研发设计、制造工艺和使用进行了对策探讨,并提出了通过合理选择截齿类型及几何参数、优化截齿安装角及叶片螺旋升角、应用摩擦学理论、使用新型截齿材料、进行表面强化、加强工人操作规范等措施提高截齿的质量,为截齿的生产提供参考依据。

Abstract

In order to improve the efficiency of coal mining and the service life of shearer,the failure mode and the reasons of cutting teeth were analyzed,and the influence caused by cutting tooth failure was described,in view of the selection,research and development design,manufacturing process and use of cutting teeth in different geological conditions,the countermeasures were discussed,and the quality of cutting teeth is improved by means of reasonable selection of the type of cutting tooth,the geometrical parameters,the optimized blade spiral angle,the application of tribology theory,the use of new cutting material,the surface strengthening and the operation of the workers. Which providing reference for the production of cutting teeth.
