目前,100～180吨机械减速的露天矿电动轮自卸汽车得到了广泛应用。在汽车运行过程中,减速器承受相当大的动载荷,这将引起一系列故障,导致汽车逐渐失效或突然失效。根据亚库特煤炭生产联合公司车队的数据,美国尤尼特里格M-200型电动轮汽车电动轮减速器的故障间期为4～10万公里,日本小松ND-1200型车的为6～15万公里。据最新资料,-7420-9590、-7519和-7521型电动轮汽车轮边减速器的故障间期波动范围更大,为2～20万公
Currently, 100 ~ 180 tons of mechanical deceleration of open-pit electric wheel dump truck has been widely used. During operation of the vehicle, the reducer is subjected to a considerable dynamic load, which causes a series of malfunctions that lead to the gradual failure or sudden failure of the vehicle. According to the Yakut coal production company’s fleet data, the United States Junitrige M-200 electric car electric wheel reducer failure period of 4 to 100,000 km, Japan’s Komatsu ND-1200-type car is 6 ~ 150,000 km. According to the latest information, -7420-9590, -7519 and -7521-type electric wheel reducer wheel width range of greater fluctuations between 2 to 200,000 km
