摘要
销轴是连采机主要零部件连接的关键零件,为提高连采机工作效率,降低销轴故障率,对目前采用的整体淬火方式与改进后的调质表面淬火工艺进行了对比分析。实践证明:采用后一种热处理方式可明显提高销轴的机械性能,延长其使用寿命。
The pin shaft is the key part for connecting the main parts of the continuous mining machine.In order to improve the working efficiency of continuous mining machine,reduce pin shaft failure rate,the whole quenching method which is currently used and the surface quenching process after quenching and tempering were analyzed.Practice proves that,the latter heat treatment method can improve the mechanical properties of the pin shaft,and prolong its service life.
