摘要：

The center of gravity of the crown cage directly affects the cage's dynamic performance in high-speed deep groove ball bearings, which in turn affects the high-speed performance and service life of the bearings. Aiming at a new type of modified crown cage, the equations between modified radius and the center of gravity were given. Combining the dynamics theory, the nonlinear dynamic differential equations of deep groove ball bearings were established. In addition, the predict-correct integral algorithm with variable step was applied to solve dynamic equations. On this basis, the relationship between modified radius and the vibration performance was analyzed. Results show that the crown cage modified radius can reduce the additional moment, and effectively reduces the vibration of the cage through changing the distance between the center of gravity and the center surface of the cage pocket. Too large or too small modified radius is not conducive to reducing the vibration of the cage. When the modified radius is 8.3 mm, the cage acceleration level reaches the minimum and the cage vibration is the lowest. As the service conditions of the bearing change, the vibration results show a trend which first increase and then decrease with the change of radial load. The vibration acceleration level of the cage increases with the increase of the bearing speed. Under the condition that the bearing operating speed is unchanged, the appropriate modified radius of the cage can be selected to reduce the vibration effect. When the ratio of the axial load to the dynamic load rating of the bearing is in the range of 0.6%-0.8%, the cage vibration result is smaller and the bearing life is longer. © 2022, Editorial Office of Journal of Vibration and Shock.
