用谐波分布理论诊断滚动轴承磨削工艺过程

Diagnosis of Grinding Process of Rolling Bearing Using Harmonic Distribution Theory

滚动表面的谐波分布对轴承的振动和噪声有重要影响 ,而谐波是在制造过程中经过不断突变和遗传形成的。结合 6 2 0 2轴承的磨削过程 ,研究用谐波分布参数诊断工艺过程的合理性问题。试验表明 ,使用该方法可以有效地控制工艺过程中轴承表面的谐波分布 。

There is an important influence of the rolling surface harmonic distribution on the vibration and noise of rolling bearings,and the harmonic is continuously generated by the mutation and heredity in the manufacture process.The rationality of the technological process is studied by the application of harmonic distribution parameters in process diagnoses,taking the grinding process of 6202 bearings as an example.The results show that the harmonic distribution on the bearing surfaces can be controlled effectively,and the processing procedures are becoming more rational by controlling harmonic distribution parameters.
