滚动轴承振动与加工质量的灰色理论分析

Grey Theory Analysis on Relation Between Vibration and Machining Quality of Rolling Bearings

运用灰色理论的广义关联度概念分析了滚动轴承的振动与加工质量各因素之间的关系。结果表明:宏观尺寸误差参数对轴承振动的影响比较大,宏观形状误差参数和微观形貌参数已达到比较高的质量水平,对轴承振动的影响比较小。而轴承的宏观尺寸参数及其公差在设计方法上存在一些问题,是影响轴承振动的主要因素。

The relationship between the vibration and machining quality of rolling bearing is analyzed with general relation degree. The results show that parameters of macroscopic dimension error exert greater effect on the vibration of rolling bearings than that of macroscopic shape parameters error and microscopic surface topography parameters which are of high quality level, while parameters of macroscopic dimension errors and its tolerance are to be the main factors.
