在矿山上进行作业的装载机,经常会遇到塌方现象,此时装载机出现等挡而来不及后退是非常危险的。针对用户反映强烈的行星式变速器等挡问题,以市场三包反馈故障为课题,通过台架试验分别对不同间隙配合的液压缸与活塞,以及市场返回的故障变速阀进行对比测试,分析造成等挡问题的根源,并据此从液压缸与活塞的配合间隙、活塞油孔数量、变速阀调压弹簧的性能,以及用户使用、保养等方面提出改进措施,通过这些措施的实施,收到明显的效果,有效地改善变速器等挡问题,提高了装载机的作业效率,消除不安全隐患。
Loaders operating on the mines often encounter landslides, and it is dangerous for the loader to wait in the opposite direction without backing back. According to the user’s strong planetary gearbox and other gear problems, the market Three Guarantees feedback fault as the subject, respectively, through the bench test with different clearances with the hydraulic cylinder and piston, and the market returned fault gear valve comparison test, analysis caused by such Based on this, we put forward improvement measures from the aspects of the clearance between the hydraulic cylinder and the piston, the number of the piston oil holes, the performance of the pressure-regulating valve spring and the users’ use and maintenance. Through the implementation of these measures, the obvious The effect of effectively improving the stalls such as transmission and improve the operating efficiency of the loader to eliminate unsafe hidden dangers.
