常见机车车轴实物对比试块的新应用

介绍利用目前现有的几种常见机车车轴实物对比试块,校验DF8B(滚抱)和DF7G型内燃机车分体轮、SS6B型电力机车整体轮、8K型机车轮对的车轴齿轮座镶入部横波探伤灵敏度的方法,以实现齿轮座镶入部和内侧卸荷槽的全面扫查。

The paper introduces how to use the common locomotive axle-kind reference blocks to verify transversal wave flaw detection sensitivity on the split wheels of DF8B （roll-hold） and DFTG diesel locomotives, mono-bloc wheels of SS6B electric locomotive, the wheel axle gear housing inlaid part of 8K type locomotive, and the full scan on gear inserted portion and the medial unloading tank. can be realized.
