摘　　要：以双列调心滚子轴承为研究对象,基于ANSYS Workbench对其等效应力、总变形和内、外圈接触应力以及内、外圈沟曲率半径系数对内、外圈最大接触应力的影响进行仿真分析。仿真结果表明,双列调心滚子轴承最大接触应力主要分布在内、外圈与双列滚动体接触位置;随着内圈沟曲率半径系数增加,内圈最大接触应力呈现增加的趋势,而外圈最大接触应力却呈现逐渐减小的趋势;随着外圈沟曲率半径系数增加,外圈最大接触应力呈现增加的趋势,而内圈最大接触应力却呈现逐渐减小的趋势。该研究为双列调心滚子轴承接触疲劳寿命的延长提供了理论依据。A double-row spherical roller bearing has been regarded as research object,the equivalent stress and total deformation,the contact stress of the inner and outer rings,and the influence of radius curvature coefficients of the inner and outer ring grooves on the maximum contact stress of the inner and outer rings have been simulated and analyzed by ANSYS Workbench.The simulation results show that the maximum contact stress of double-row spherical roller bearing is mainly distributed in the contact position between the inner and outer rings and the double-row rolling elements;with the inner ring groove curvature radius increasing,the maximum contact stress of the inner ring appears to increase,while the maximum contact stress of the outer ring gradually decreases;with the outer ring groove curvature radius increasing,the maximum contact stress of the outer ring is increasing,but the maximum contact stress of the inner ring is gradually decreasing.The research provides a theoretical basis for the extension of contact fatigue life of double-row spherical roller bearing.
