摘要
针对MG900/2210-GWD型采煤机在进行采煤作业期间出现的摇臂中心水路泄露、润滑油乳化、齿轮失效以及行走箱花键轴频繁断裂的问题,提出了改进方案。实践表明:改进后的采煤机在实际运行中效果良好,不仅故障发生的可能性大大减少,而且实现了煤矿的安全高效生产。
Aiming at the problems such as the leakage of the cen ter water of rocker arm,the emulsification of lubricating oil,the failure of gear and the frequent fracture of spline shaft in the walking box of MG900/2210- GWD shearer during the coal mining operation,the improvement scheme is put forward. The practice shows that the improved shearer has a good effect in practical operation,which not only reduces the probability of failure greatly,but also realizes the safe and efficient production of coal mine.
