自行车轴碗易磨损,因轴碗孔径与轴皮孔径相差不多,故拆卸时较困难,现介绍两种简易方法。 电焊法 将一段φ10mm长约200mm的圆钢插入轴碗内(图1),前端略突出轴碗内孔,焊接圆钢与轴碗之间及轴碗开裂处,迅速敲打圆钢另一端,轴碗即可卸下。此法特别适用于轴碗开裂严重时,但 Bicycle shaft bowl easy to wear, because the shaft bowl aperture and shaft skin aperture almost the same, it is more difficult to disassemble, are introduced two simple methods. Welding method will be a section of φ10mm about 200mm round bar into the shaft bowl (Figure 1), the front slightly protruding shaft bore hole, welded bar and shaft bowl and shaft bowl cracking at the other end of the rapid beat on the shaft Bowl can be removed. This method is particularly suitable when the shaft bowl cracking serious, but
