臂架式斗轮堆取料机回转轴承及配重优化改进

Optimization improvement of swing bearing and balance weight of outrigger bucket-wheel stacker-reclaimer

采用液压顶升法对臂架式斗轮堆取料机回转轴承进行了更换,分析了堆取料机回转轴承外圈连接螺栓较大面积断裂以及前臂架不能正常起升的原因,提出了对堆取料机回转轴承以及后臂架配重进行优化改进的方案。

The hydraulic jacking method is used to replace the swing bearing of the bucket wheel stacker / reclaimer.The paper analyzes the causes of large bolting breakage of swing bearing outer ring of the stacker / reclaimer and forearm failing to normally rise,and puts forward schemes to optimize and improve the swing bearing outer ring of the stacker / reclaimer and forearm balance weight.
