包钢白云鄂博铁矿主采场共有KY-310A型牙轮钻机6台,在使用过程中,经常出现结合体颈部被减速箱内的铁屑磨损,导致密封圈失效,减速箱润滑油大量外漏,维修与更换频繁,影响设备的正常使用。1原结合体的密封方式原结合体的密封方式如图1所示,结合体内壁有一凹槽,用于放置O形密封圈5,与中空轴3进行配合密封,以防漏油。
There are 6 KY-310A-type cone drills in the main stope of Baonang Bayanobo Iron Mine. In the process of using, the iron neck of the combination body neck is often worn by the iron in the reduction gearbox, resulting in the failure of the seal ring and the large amount of gearbox lubricating oil Leakage, frequent maintenance and replacement, affecting the normal use of equipment. 1 original combination of the sealing method The original combination of sealing as shown in Figure 1, the combination of the body wall has a groove for placing O-ring 5, with the hollow shaft 3 with the seal to prevent oil leakage.
