摘要:为优化深沟球轴承-转子系统性能,提高其稳定性,以单列深沟球轴承为基础,使用SolidWorks和ADAMS软件联合建立了深沟球轴承-转子系统的多体动力学仿真模型。分析在相同转速、相同外力条件下,分别改变深沟球轴承滚动体的直径、数量时,转子在竖直方向的振动及达到稳定状态所需时间。在将结果对比分析后发现,在相同条件下,滚动体数量越多,滚动体半径越接近内外沟道曲率半径的较小值、转子振幅越小,到达稳定值的位移越小、时间越短。

Abstract: Aiming at optimizing the performance of the deep groove ball bearing-rotor system and improving its stability, a multi-body dynamics simulation model of a deep groove ball bearing-rotor system was established using SolidWorks and ADAMS software based on a 6206 single-row deep groove ball bearing. With the same rotational speed and external force, we analyzed the vibration of the rotor in the vertical direction and the time required to reach the steady state when changing the diameter and number of the deep groove ball bearing rolling bodies. Comparing the results, we found that in the same conditions, the greater the number of rolling elements and the closer the radius of the rolling element is to the smaller value of the radius of curvature of the inner and outer channels, the smaller the amplitude of the rotor, the smaller the displacement reaching the stable value, and the shorter the time.
