风电轴承FL-HSB2421 D表面硬度及有效硬化层深度的检测方法

Test Method for Surface Hardness and Case Hardened Depth of Wind Power Bearing FL-HSB2421D

据统计,大约有20%的风机故障是由于轴承失效引起的,而轴承工作面硬度及有效硬化层深度直接影响其使用寿命[1]。针对这个问题,我们使用维氏硬度检测方法对轴承表面硬度以及有效硬化层深度进行检测,最终准确测得硬度值及深度。

According to statistics,about 20%of wind turbine faults are caused by bearing failure.The surface hardness and case hardened depth directly affect the service life of bearing.To solve this problem,we use Vickers hardness testing method to test the surface hardness and case hardened depth of bearing and finally obtain accurate measurement results.
