普通活顶尖里的轴承需要更换时,因为圆锥滚子轴承与顶尖锥柄部分间隙太小,轴承不易取出。我厂李在洪师付想出了一个如图所示的简便方法,在顶尖内部增加了一个螺母垫圈,更换轴承时,把螺栓套进螺母垫圈,旋转螺栓,迫使圆锥滚子轴承被推出。 Ordinary live in the top bearing needs to be replaced, because the tapered roller bearing taper shank and the top part of the gap is too small, the bearing is not easy to remove. In our factory, Mr. Li Zhaofu came up with a simple method as shown in the figure, adding a washer in the top. When replacing the bearing, the bolt was put into the nut washer and the bolt was rotated to force the tapered roller bearing to be pushed out.
