1.故障现象哈尔乌素露天煤矿1台比塞洛斯(BUCYRUS)495HR型电铲自身质量为1412t,斗容量为60.4m~3,主要用于矿区剥离岩石和开采矿石。该电铲于2007年开始使用,在长期使用过程中,其回转减速器支架产生晃动,造成回转减速器不能正常运行。为此,我们分析回转减速器支架晃动原因,制定并实施修复工艺。495HR型电铲回转减速器支架如图1所示。2.原因分析经分析,我们认为该电铲回转减速器支架产生晃动的原因有5个方面,如下所述。一是长期满负荷运行产生严重磨损。该电铲
1. Symptom One Buick opencast coal mine BUCYRUS 495HR shovel has a mass of 1412t and a bucket capacity of 60.4m ~ 3, which is mainly used for stripping rock and mining ore in the mining area. The shovel began to be used in 2007, in the long-term use, the slewing reducer bracket sway, resulting in rotary retarder can not be normal operation. To this end, we analyze the reasons for slewing reducer bracket shake, develop and implement the repair process. 495HR shovel rotary reducer bracket shown in Figure 1. 2. Analysis of the Cause After analysis, we think there are five aspects to the sloshing of the power shovel slewing reducer bracket as follows. First, long-term operation at full capacity have serious wear and tear. The shovel
