摘要/Abstract

摘要： 建立了鼠笼柔性支撑一体化轴承的FEM-拟动力学迭代分析模型,采用FEM模型计算支撑结构和轴承滚道的变形,采用非圆滚道的拟动力学模型分析轴承动态特性。研究了一个鼠笼支撑一体化球轴承在载荷作用下的内部载荷分布,分析了柔性支撑一体化结构对球轴承动态特性的影响。结果表明,鼠笼支撑一体化结构使轴承内部最大接触载荷减小了10.94%,疲劳寿命增加了11.3%,轴承刚度大幅降低,打滑率上升了15.8%。并且,轴承套圈壁厚越厚,结果越接近刚性支撑假设的计算结果;轴承套圈壁厚越薄,鼠笼支撑带来的影响越显著。

Abstract: An integrated squirrel-cage flexible support ball bearing quasi-dynamic iterative Finite Element Model (FEM) is established, which is used to calculate the deformation of the support structure and raceway. The dynamic characteristics of the bearing are analyzed using the noncircular raceway quasi-dynamic model. The internal load distribution of the integrated squirrel-cage flexible ball bearing is studied, and the influence of the integrated flexible support structure on the dynamic characteristics of the bearing is analyzed. The results show that the integrated squirrel-cage flexible support structure reduces the maximum bearing internal contact load by 10.94%, increases the fatigue lifetime by 11.3%, reduces the bearing radial stiffness by an order of magnitude, and increases the slide ratio by 15.8%.
