经十余年使用观察,发现该机的轮毂与轴套配合不合理,润滑黄油往往从轮毂与轴套之间的间隙跑掉,致使轴与轴套得不到润滑,造成早期磨损。并只靠二十螺钉无法固紧轮毂与轴套。根据以上存在的问题,我们做了改进,经使用效果良好。改进方法:将轮毂2内孔改为锥形孔;轴套1外径制成锥形体与轮毂内孔配合;轴套前端车有螺纹用固定挡圈固定在轮毂上;外端带有防尘盖4,黄油从防尘盖注入即可。
After more than ten years of using the observation, it was found that the hub of the aircraft did not cooperate with the hub. Lubricating butter often ran away from the gap between the hub and the hub, resulting in no lubrication of the shaft and the hub, resulting in early wear. And only by twenty screws can not tighten the hub and sleeve. Based on the above problems, we made improvements, the use of good results. Improved method: change the inner hole of the hub 2 into a conical hole; the outer diameter of the hub 1 is made into a conical body and is matched with the inner hole of the hub; the front end of the hub is threaded with a retaining ring fixed on the hub; Cover 4, butter can be injected from the dust cover.
