ABSTRACT
At high rotational speed operating condition, there is much significance to analyze the bearings dynamic rigidity, especially when the supporting precision is required. Based on classic analysis methods and essential theories of ball bearing, including Hertz contact theory and raceway control theory, develop a solving procedure to analyze the dynamic rigidity of high-speed angular contact ball bearing, according New-Raphson method. This procedure is greatly simplified and easy to be realized by program, since the correlations of the variables are founded. Selecting HP7005CTA under the fixed-pressure preload, used in high-speed motorized spindle as an example, we calculate the contact deformation, stress and angle between ball and raceway, then conclude the bearings dynamic rigidity. The results show the effects of axial preload, rotational speed, inner and outer raceway curvature on bearings axial, radial and angular rigidity.
