KQD-80多方位潜孔钻机回转减速箱(图1)中,回转输出轴与调整堵的内孔常出现互研现象,维修时必须将回转输出轴与调整堵内孔的互研处进行机加工整修。这给用户带来很大不便,且有时卸下调整堵导致回转输出轴与调整堵内孔互研严重而需报废。本钻机的冲击器有“劲”不能充分发挥,使效率受到影响。下面对这些进行一些分析和提出改进意见。一、造成回转输出轴与调整堵内孔互研的原因分析:
In the KQD-80 multi-directional submersible drilling rig gyration gearbox (Figure 1), the rotating output shaft and the inner hole of the adjusting plug often exhibit mutual development phenomenon. During the maintenance, the mutual machining of the rotating output shaft and the adjusting plug hole must be machined and repaired. . This brings great inconvenience to the user, and sometimes the removal of the adjusting plug causes the rotary output shaft and the adjusting plug bore to be severely interrogated and needs to be scrapped. The impactor of this rig is not able to give full play to the impact and the efficiency is affected. Here are some of the analyses and suggestions for improvement. First, the cause of the analysis of the rotation output shaft and adjust the plug hole mutual analysis:
