摘要
在隧道盾构掘进过程中,渗漏的地下水与渣土形成的泥水混合物对输运电机车组的传动部件会产生渗透堵塞的状况。本文分析研究了后轴结构密封系统泥水渗漏和磨损失效的因素,并基于强化动静结合处的抗磨性和耐用性的机理要求,提出了增加浮动油封、同时将轴承密封系统中的所有密封圈换成耐用性更强的唇型密封圈等优化措施,有效减轻了泥水环境下的后轴轴承泥水的渗漏,提高了密封结构的耐用性和使用年限,提高了泥水盾构用电机车组的使用效率。
In the process of shield tunneling,the mixture formed by mud and leaked groundwater caused seepage and blockage on the transmission parts of electric locomotives.In this paper,the factors of mud leakage and wear failure of the sealing system of rear shaft structure were analyzed and studied.Based on the mechanism requirements of strengthening the wear resistance and durability of the dynamic and static joint,the optimization measures such as adding floating oil seal and replacing all sealing rings in the bearing sealing system with more durable lip sealing rings were put forward.The methods effectively reduced mud leakage of the rear shaft bearing in the muddy water environment,improved the durability and service life of the sealing structure,and improved the efficiency of the slurry shield electric locomotive crew.
