摘　　要：使用磁粉探伤来检测大型磨机齿轮时,因其效率低和耗时长等问题限制了对齿轮全方位的检测。笔者使用涡流阵列对澳大利亚大型球磨机齿轮进行试验性检测,检测结果证明:涡流阵列较磁粉探伤可节约80%的检测时间,且检测结果以扫描图像形式显示,可快速有效地判定其缺陷,有助于对磨机齿轮状态进行分析。The magnetic particle testing method is used to detect the girth gear of the large-scale mill, while its low efficiency and long consuming time limit the omni-directional detection of the girth gear. In the paper, the eddy current array detection was applied to detect the girth gear of a large-scale in Australia. The detection results showed: the eddy current detection saved by 80% detection duration compared with the magnetic particle testing method, and the detection results displayed in the form of scanning images. Thus the defects were rapidly and effectively identified, which was conducive to the analysis of the girth gear of the mill.
