摘要

井下采煤机摇臂是采煤机械的核心设备,摇臂齿轮传动系统具有重载、齿轮传动难以润滑等特征,其工作可靠性对井下采煤安全和采煤经济效益具有重要影响。为此,针对某型摇臂齿轮传动系统故障特征,通过对传动齿轮断齿和点蚀、轴承磨损和胶合等部位的失效分析,以及润滑油的物理特性试验测试分析,揭示其故障机理。研究结果表明,选用润滑油的物理特性对传动系统具有重要影响,如果其选用和维护不当,易导致润滑油运动黏度无法满足润滑需求,从而引起传动系统发热量过大,造成轴承破坏,齿轮局部过载,发生齿面点蚀和局部断齿,进而导致摇臂齿轮传动系统失效。研究工作为重载齿轮传动系统设计、使用和维护提供了十分有价值的参考。

Abstract

The rocker arm of underground shearer is the core equipment of coal mining machinery. The transmission system of rocker arm machine has the characteristics of heavy load,and the gear transmission system is difficult to lubricate,its working reliability has an important influence on the coal mining safety and the economic benefit of coal mining. Therefore,through the typical parts failure analysis of gear breaking and pitting corrosion of the transmission gears,bearing wear and gluing,and the physical characteristics test analysis of lubricating oil,the fault mechanism for the transmission system of rocker arm machine is studied. The results show that the physical properties of the selected lubricating oil have an important influence on the transmission system. Due to improper selection and maintenance of lubricating oil,the viscosity of the lubricating oil can not meet the lubrication requirements,which leads to the over-heating of the transmission system,bearing failure and partial overloading of the gear,even tooth pitting and partial broken teeth occurs,and further leads to the failure of the rocker gear transmission system. The research work provides a valuable reference for designing,using and maintaining of heavy-duty gear transmission systems.
