保持架的旋转频率的非重复跳动（NRRO）主要是由包含在一个轴承中的球的直径差异引起的。此外，已知球的不等轨道间隔会影响保持架的旋转频率的NRRO。然而，关于这一点的定量研究很少。在这项工作中，我们研究了球的轨道间隔不相等对故意拔出球的保持器旋转NRRO的影响。我们澄清了如果球的轨道间隔之间的差异大，则保持架的旋转频率的NRRO变大。
The nonrepetitive runout (NRRO) of rotational frequency of a cage is caused mainly by the diameter differences of balls contained in one bearing. In addition, it was known that unequal orbital intervals of balls could influence the NRRO of the rotational frequency of the cage. There were few quantitative studies about this, however. In this work, we investigated the influence of unequal orbital intervals of balls on the NRRO of retainer rotation by pulling out balls intentionally. We clarified that the NRRO of rotational frequency of the cage became large if the difference between orbital intervals of balls was large.
