摘要
为了尽量减少露天挖掘机机电故障率与提高其运行效率,对东北某露天煤矿挖掘机齿轮失效进行了统计分析,得出了齿面点蚀与齿轮磨损是挖掘机齿轮失效的主要形式。对4种齿轮失效形式的具体原因进行了分析,在此基础上提出了关于配件采购、保养维护、油液监测等一系列的预防措施,对于改善露天挖掘机运行效率具有显著实践意义。
In order to minimize the failure rate and improve the operating efficiency of excavators, this article carries out the statistical analysis on excavator gear failure and obtains that pitting corrosion and gear wear is the main form of excavator gear failure. The author analyzes the specific reasons of 4 kinds of gear failure forms, on this basis, and presents a series of preventive measures on procurement, maintenance, oil monitoring, which has practical significance to improve the excavator operating efficiency in open-pit mine.
