摘 要： An investigation was carried out to explain the ball bearing stiffness which took into account the bearing ring flexibility, and the relationship between the deformation of the bearing ring and the stiffness of the ball bearing under an axial load. In this study, first, the axial stiffness of the ball bearing under the axial load and the deformation of the outer ring were measured. Second, the calculation method of the bearing stiffness incorporating the bearing ring flexibility was proposed. Third, the validity of the presented calculation method was discussed. Fourth, the deformation of the bearing ring was discussed. From the results of experiments and analysis, the conclusions were obtained as follows: (1) The calculation method of the hearing stiffness incorporating the bearing ring flexibility was proposed. The axial stiffness of the ball bearing under the axial load can be estimated using the presented calculation method. (2) The outside surface of the outer ring of the hearing under the axial load causes a deformation in the pyramid with the polygonal number a. The polygonal number a is equal to the number Z of balls. The bottom face of the pyramid is where the axial load is applied. (3) The out of roundness of the periphery of the outer ring of the ball hearing under the axial load changes with the axial position of the outer ring. The axial position where the out of roundness is maximized coincides with the axial position of the contact point between the ball and the outer ring.

为了解释轴承刚度，本研究考虑了轴承环的柔性和轴向载荷下轴承环变形与球轴承刚度之间的关系。首先，测量了球轴承在轴向载荷下的轴向刚度以及外圈的变形； 其次，提出了考虑轴承环柔性的轴承刚度计算方法； 第三，讨论了该计算方法的有效性； 第四，分析了轴承环的变形情况。通过实验结果和分析，得出以下结论：（1）提出了一种考虑轴承环柔性的轴承刚度计算方法，可利用该方法估算球轴承在轴向载荷下的轴向刚度。（2）在轴向载荷作用下，轴承外圈的外表面会产生一个边数为a的多边形变形，其中边数a等于滚珠数量Z。金字塔的底部是轴向载荷作用的位置。（3）在轴向载荷作用下，外圈球轴承边缘的偏心度会随外圈的轴向位置变化。当偏心度达到最大值时，其轴向位置与球和外圈接触点的轴向位置一致。
