根据深沟球轴承元件运动几何关系建立数学模型，空载下对轴承运动状态进行数值仿真和模拟，分析了深沟球轴承滚球直径误差、内外圈滚道圆度误差对回转精度的影响规律。结果表明，随着单一滚球误差的增加，轴承回转精度变差；多个滚球存在误差时，随着滚球的误差梯度增加，轴承回转精度变差；内外圈滚道分别存在几何形状误差时，误差阶次不变，随着误差幅值的增加，轴承回转精度变差；误差幅值不变，随着误差阶次的增加，内外圈滚道误差阶次与滚球数目具有周期性的映射关系。

Based on the relationship between the movement and geometry of deep groove ball bearing ele-ments, a mathematical model was established to simulate the motion state of deep groove ball bearing under unloaded. Taking the ball diameter error, inner and outer ring raceway roundness error into consideration to analysis the influence of the rotation accuracy . The results show that the rotation accuracy of bearing would be low when with the increasing of single ball errors;the rotation accuracy of bearing would be low when multiple ball exist error which with the increasing of the error gradient; the rotation accuracy of bearing would be low with the increasing of the amplitude of error when the inner and outer ring raceway geometry errors exist,but the flaps number of error was constant;there has been a periodic mapping relationship be-tween inner/outer ring raceways flaps number of error and the number of ball when the flaps number of error was increased,but the amplitude of error was constant.
