盲孔内的轴套拆卸时很棘手,在维修中即使借助专用拔具效果也不好。如何快速拆卸盲孔内的轴套,提高排故效率,应该对盲孔结构进行改进,办法是把盲孔深度加深,加深的尺寸等于拆卸垫的厚度。制作拆卸垫,其外径尺寸比盲孔直径小0.2mm。厚度根据轴套直径大小,按正比例关系确定尺寸。在拆卸垫的中心制出一个合适螺孔。改进后的结构如图所示。
Blind hole sleeve dismantling very difficult, even in the maintenance of the use of special drawing effect is not good. How to quickly disassemble the bush in the blind hole and improve the efficiency of troubleshooting should be improved blind hole structure by deepening the depth of the blind hole deepening the size equal to the thickness of the disassembly pad. Production disassembly pad, the diameter of the blind hole diameter smaller than 0.2mm. According to the thickness of the sleeve diameter, determine the size according to the proportional relationship. Make a suitable screw hole in the center of the disassembly pad. Improved structure as shown.
