一、旧矿车在结构上存在的问题我国煤矿生产战线上正在使用的矿车大约有100万辆左右,承担着煤矿的主要运输任务。其中85%以上是MGC1.1-6型1 t铁矿车,这种矿车在结构和性能上都比较落后,存在以下主要问题。1.轮与轴之间的密封不严,矿水和泥沙容易进入轴承室,涮走了润滑脂并加剧滚动轴承的磨损。个别严重的会使轴承寿命减少半年(一般矿车的轴承寿命大约一年左右)。2.矿车连接器与碰头和碰头座之间在挂车时常产生冲击,常使橡胶碰头破损,有时
First, the old mining car in the structural problems China’s coal production front is about the use of the tub about 1 million vehicles, the main transport tasks bear. More than 85% of them are MGC1.1-6 1t iron car, which is relatively backward in structure and performance and has the following major problems. 1. The tight seal between the wheel and the shaft, easy entry of mine water and sediment into the bearing chamber, rinsing away the grease and aggravating the wear of the rolling bearing. Some serious will reduce the bearing life six months (the general bearing life of the tub about a year or so). 2. Between the car connector and the meet and meet the first seat in the trailer impact, often make the rubber break, sometimes
