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.关键词
