摘要

摘要: 角接触球轴承是涡轮泵发射系统中的关键元件之一。轴承的径向支撑刚度对涡轮泵发射系统的性能有着十分重要的影响, 为了获取可靠的轴承径向支撑刚度, 以Hertz接触理论和轴承几何关系为基础, 推导了角接触球轴承径向刚度计算模型, 考虑了系统轴向预紧载荷与径向载荷的耦合作用、径向间隙和过盈量, 分析了不同因素对轴承径向刚度的非线性影响规律。文中的分析结果可为旋转机械整体分析提供参考。

Abstract: Angular contact ball bearing is one of the key components in turbopump launch system, and its radial stiffness is vital for the performance of the turbopump launch system. To obtain reliable radial stiffness of the angular contact bearing, this paper derives a formulas for calculating the radial stiffness according to the Hertz contact theory and the geometrical relationship of the bearing. This formula considers the coupling of axial preload and radial load, the radial clearance, and the interference magnitude. Moreover, the nonlinear influences of different factors on the radial stiffness are analyzed. This study may provide a reference for integral analysis of rotating machine.
