摘　　要：考虑离心力、陀螺力矩、滚子偏斜以及套圈挡边与滚子球基面之间的润滑,建立联合载荷作用下圆柱滚子轴承力学分析模型,基于该模型分析了滚子球基面半径对轴承接触特性及发热量的影响,结果表明:随滚子球基面半径增大,接触点距离滚道表面越近,最大接触应力越小,发热量越少。基于轴承寿命理论对不同偏差的内、外圈挡边倾角和滚子球基面半径进行匹配优化,轴承寿命可提升约34%。Considering centrifugal force,gyroscopic moment,roller misalignment and lubrication between ribs of rings and spherical reference surfaces of rollers,a mechanical analysis model of cylindrical roller bearings under combined load is established.Based on this model,the influence of radii of spherical reference surfaces of rollers on contact characteristics and heat generation of the bearings is analyzed.The results show that with the increase of radii of spherical reference surfaces of rollers,the closer the contact point is to raceway surface,the smaller the maximum contact stress and the less the heat generation.Based on theory of bearing life,the matching and optimization of tilt angles of ribs of inner and outer rings and radii of spherical reference surfaces of rollers with different deviations improve the bearing life by about 34%.
