在设备维修过程中,拆轴承、卸衬套是司空见惯的,而盲孔中的衬套的退出就比较困难。针对这一问题,我们设计制作了拔盲孔衬套工具,经过长时间的生产检验,证明效果很好。 该工具由弹性勾爪螺母、螺栓顶杆、止动扳手以及旋转扳手等主要部件构成(图1)。 In the equipment maintenance process, it is commonplace to disassemble the bearings and unload the bushing, and the bushing in the blind hole is more difficult to exit. In response to this problem, we designed and manufactured a blind hole bushing tool, after a long period of production testing, proved effective. The tool is made up of the main components of a flexible check claw nut, bolt plunger, stop wrench, and a rotary wrench (Figure 1).
