滚动轴承内圈滚道表层残余应力分布实验研究
Experimental study on residual stress distribution in surface layer of rolling bearing inner ring raceway
摘要
Abstract
Taking the B7008C/P4 bearing inner ring raceway for example ,the residual stress distribu‐tions in the surface layers were measured by layer removal and X‐ray diffraction .Finite element meth‐od was used to analyze the stress relaxation due to layer removal ,which can correct the stress meas‐urements .The results show that the maximum relative error between measured residual stress and corrected residual stress is 3 .9% ,w hile the thicknesses of the removed layers are micron scale .Be‐sides ,the errors increase with the increasing thicknesses of removed layers .The comparative analysis between domestic and foreign B7008C/P4 bearings show that the foreign bearing inner ring raceways have greater surface compressive residual stress and deeper depth of severely reduced compressive re‐sidual stress ,w hich is more conducive to improve bearing fatigue life .关键词
