内圈径向跳动值的幅值减小，内圈大径向跳动值呈现出递减的趋势；当谐波阶次为滚子个数的整数倍时，内圈大径向跳动值达到极大值。2）随着圆度误差幅值的增大，内圈径向跳动值及其幅值都明显增大，内圈大径向跳动值呈现出明显上升的趋势。这表明内圈滚道圆度误差幅值是影响轴承旋转精度的主要因素之一。

(3)在超精工序中，油石沿滚道素线方向往复振动，增大了滚道中部的超精量，滚道素线会出现向下凹的情况，影响成品滚道凸度量。总结：轴承滚道凸度的加工过程中。砂轮修整是一个核心问题，砂轮修整频次与砂轮硬度、粒度、工件尺寸、形状、材质、冷却状况等众多因素有关。谐波阶次对轴承旋转精度的影响图1为内圈滚道谐波阶次为10阶和42阶时轴承内圈旋转一周其径向跳动历程。

但对轴承设备的运行数据收集、退化故障特提取、健康状态评估、剩余寿命预测等关键技术的研究则开展很少，因此加大这方面的研究对进一步提升轴承的寿命使用性能具有重要的理论意义及应用价值。关键词：滚动轴承；可靠性；大数据；健康监测；寿命预测滚动轴承是决定机械健康状态与寿命的关键部件之一。轴承寿命及其健康状态的研究存在影响因素多、寿命分散度大、试验费时、数据积累难、理论建模难等特点。
