矿车是煤矿运输设备中数量最多、维修量最大的一种 设备，在矿车损坏中，轮对损坏又是最严重的。本人走访了福建省许多煤矿，发现由于轮对故障而引起矿车损坏的比例高达７０％以上。因此，分析矿车轮对常见故障，加强矿车维修管理工作，提高轮对的可靠性和使用寿命，延长服务年 Mine car is the largest number of coal transport equipment, the largest amount of maintenance of a device in the car damage, the wheel is the most serious damage. I visited many coal mines in Fujian Province and found that as a result of the failure of the wheel car damage caused by the proportion of up to 70%. Therefore, the analysis of mine wheel on the common fault, strengthen the management of tub maintenance, improve wheelset reliability and service life, extended service years
