| 摘 要： | 某型号液压泵在进行疲劳试验过程中发生主轴断裂。采用扫描电镜等方法对其进行分析,结果表明该主轴的断裂是在受到较大的剪切弯曲作用力下形成的疲劳断裂;由于该主轴所用材料内存在大量的非金属硫化物夹杂,从而对裂纹的形成及扩展起到了推进作用。

| 关 键 词： | 主轴 疲劳裂纹 硫化物夹杂 |

| Abstract: | A spindle of hydraulic pump was cracked in fatigue test. Analyzed by electron microscopy scanning ,it showed that the spindle fatigue fracture was due to great radial power at torsion. Meanwhile, the material of spindle contains a lot of non-metallic sulfide. It causes cracks and their spread. |

| Keywords: | spindle fatigue crack sulfide |
