摘要： 保持架是角接触球轴承的重要元件之一，其引导间隙和兜孔间隙设计不合理会导致轴承运动失稳与共振。针对上述问题，在理论分析的基础上，结合滚珠、保持架和滚道之间的动态接触与变形关系，在ABAQUS软件中建立了7005型角接触球轴承的显式动力学模型，并提取了特定工况下该轴承内圈、保持架与滚珠的动态响应曲线；同时，研究了不同引导间隙和兜孔间隙下保持架的打滑率、质心涡动速度偏差比和各阶振动模态的固有频率。为了验证所建立的角接触球轴承显式动力学模型的准确性，对高速角接触球轴承各元件线速度的仿真值与理论值进行了对比。结果表明：随着引导间隙的增大，保持架的打滑率、质心涡动速度偏差比和各阶振动模态的固有频率均减小，保持架的稳定性增强，但共振风险增大；随着兜孔间隙的增大，保持架的打滑率增大，质心涡动速度偏差比变化不明显，各阶振动模态的固有频率减小，保持架的稳定性减弱，共振风险增大。高速角接触球轴承各元件线速度的仿真值与理论值的最大误差仅为0.099 6%，验证了所建立的显式动力学模型的准确性。研究结果可为高速角接触球轴承保持架的优化设计提供理论依据。
Abstract: The cage is one of the important components of the angular contact ball bearing, and the unreasonable design of the guide clearance and pocket clearance will cause the instability and resonance of the bearing. Aiming at the above problems, on the basis of theoretical analysis, combined with the dynamic contact and deformation relationship among the ball, the cage and the raceway, the explicit dynamics model of 7005 type angular contact ball bearing was established in the ABAQUS software. The dynamic response curves of the inner ring, the cage and the ball of the angular contact ball bearing under the specific working conditions were extracted. At the same time, the slip rate, the deviation ratio of centroid whirl velocity and the natural frequency of each order vibration mode of the angular contact ball bearing cage with different guide clearances and pocket clearances were studied. In order to verify the accuracy of the established explicit dynamics model of angular contact ball bearing, the simulated values and the theoretical values of the linear velocity of each component of the high-speed angular contact ball bearing were compared. The results showed that with the increase of guide clearance, the slip rate, the deviation ratio of centroid whirl velocity and the natural frequency of each order vibration mode of cage decreased simultaneously, and the stability of cage was enhanced, but the risk of resonance increased; with the increase of pocket clearance, the slip rate of cage increased, the deviation ratio of centroid whirl velocity did not change significantly, the natural frequency of each order vibration mode decreased, the stability of cage decreased, and the risk of resonance increased. Furthermore, the maximum error between the simulated value and the theoretical value of the linear velocity of each component of the high-speed angular contact ball bearing was only 0.099 6%, which verified the accuracy of the established explicit dynamics model. The research results provide a theoretical basis for the optimal design of high-speed angular contact ball bearing cages.
