我矿采矿运输使用的3.5米~3双侧可卸式矿事,投入生产以后不到一年,就有80％由于零件损坏严重,陷于不堪使用状态。分析其原因是原设计的车箱重心过高,支撑车箱的支架位于底座中心,借助四角拉练平衡,装入矿石后由于重心位移,导致运行时不稳定。因此,轮组轴向窜动,加剧了滚动轴承磨损,增加了备件消耗;车箱强度不够,侧箱板变形成鼓状,促使两端联杆湾曲,因而在卸矿
In the less than one year after 3.5m ~ 3 bilateral detachable mining operations used in mine mining and transportation, 80% of them are in a state of being unbearable due to serious damage to the parts. Analysis of the reason is that the original design of the car center of gravity is too high, supporting the carriage bracket located in the center of the base, with the four corners of the training balance, due to the center of gravity after loading into the ore, resulting in unstable operation. Therefore, the axial movement of the wheelset exacerbates the wear of the rolling bearing and increases the consumption of spare parts. The strength of the vehicle box is not sufficient, the side box board is deformed into a drum shape, prompting the crank at both ends of the link rod,
