机 械修配厂检修时常常要拆卸装在盲孔轴承座内的轴承 ,取出这类旧轴承的工作是很困难的 ,如果使用图示芯轴就方便、容易了。1结构和工作原理芯轴4用冷轧钢棒料制成 ,其左端直径要大于欲取出旧轴承6的内径4～6mm;右湍车削加工到约比轴承6内径小0.025～0.05mm ;在棒料中心钻一个 Mechanical repair shop repair often remove bearings installed in the blind hole bearing, remove the work of such old bearings is very difficult, if the use of the illustrated mandrel convenient and easy. 1 structure and working principle Mandrel 4 made of cold-rolled steel bar, the left end diameter greater than the inner diameter of the old bearing 6 to be removed 4 ~ 6mm; right turret turning machining to about smaller than the inner diameter of the bearing 6 0.025 ~ 0.05mm; Drill a bar center
