| 摘 要： |
The dynamic performance of angular contact ball bearings is greatly affected by preload force and preload mechanisms. In the present research, a comparison model is built to analyze the stiffness of angular contact ball bearings under different preload mechanisms. In the first part, the elastic deformation of inner ring of bearing produced by assembling stress and centrifugal stress is calculated. Then the differences of two different types of preload on the action mechanism of bearings are discussed. Based on these, a comparative model of ball bearing and stiffness with respect to different preload mechanisms is proposed. Finally, the influences of the inner ring interference value, rotating speed and radial load on the bearing characteristics and stiffness-are discussed in detail. The results show that under fix-positon preload, the bearing have a better stability of stiffness, and the inner ring interference value and rotating speed also have a significant influence on the bearing dynamic properties and stiffness. In addition, the proposed model is validated by comparing the results obtained by the proposed method with those from the other literatures and experiments. (C) 2017 Elsevier Ltd.

角接触球轴承的动态性能受到预载力和预载机制的显著影响。本研究建立了一个对比模型，用于分析不同预载机制下角接触球轴承的刚度特性。首先计算了由装配应力和离心应力引起的内圈弹性变形，然后讨论了两种不同预载方式对轴承工作机理的影响差异。在此基础上，提出了针对不同预载机制的轴承与刚度的对比模型。最后，详细探讨了内圈干涉值、转速和径向载荷对轴承性能及刚度的影响。结果表明，在固定位置预载条件下，轴承的刚度稳定性更优，而内圈干涉值和转速也对轴承的动态特性和刚度具有显著影响。此外，所提出的模型通过将本方法得到的结果与其他文献及实验数据进行比较得到了验证。(C) 2017 Elsevier Ltd.版权所有。 |
