【摘要】：在轴承几何关系和运动关系分析基础上,建立了考虑内圈滚道廓形的圆柱滚子轴承径向跳动数学模型,分析了内圈滚道圆度误差幅值、谐波阶次、滚子个数以及径向游隙对轴承旋转精度的影响规律,并验证了模型的正确性.结果表明:内圈滚道的圆度误差对轴承旋转精度的影响较大,内圈滚道圆度误差幅值对轴承旋转精度影响较大,内圈滚道低阶谐波对轴承旋转精度的影响较高阶谐波显著;当内圈滚道谐波阶次为滚子个数的整数倍时,轴承旋转精度显著下降;减小内圈滚道圆度误差幅值能有效提高圆柱滚子轴承的旋转精度.
[Abstract]:Based on the analysis of the geometric and kinematic relations of the bearing, a mathematical model of radial runout of the cylindrical roller bearing considering the inner ring raceway profile is established, and the amplitude of the roundness error of the inner ring raceway and the harmonic order are analyzed. The effect of roller number and radial clearance on bearing rotation accuracy is verified. The results show that the roundness error of the inner ring raceway has a great influence on the bearing rotation accuracy, the amplitude of the inner ring raceway roundness error has a great influence on the bearing rotation accuracy, and the lower order harmonics of the inner ring raceway have more significant influence on the bearing rotation accuracy than the high-order harmonics. When the harmonic order of the inner ring raceway is integer times of the number of rollers, the rotation accuracy of the bearing decreases significantly, and the rotation accuracy of the cylindrical roller bearing can be improved effectively by reducing the amplitude of the raceway roundness error of the inner ring.
