Influence of Combined Load on Dynamic Behavior of Angular Contact Ball Bearing with Various Conditions

The traditional analysis of dynamic characteristics inside a ball bearing mainly focuses on the kinematic trajectory in the steady condition, while various working conditions are often neglected in investigations. A general approach for dynamic modeling and analysis of an angular contact ball bearing (ACBB) considering combined load effects is proposed in this work. In the analytical model, the characteristics of contact-impact are considered and a dissipative contact model is employed to represent energy loss effects. A dynamic performance experiment of an ACBB is performed, which illustrates that the proposed model can be satisfied with the evaluation of dynamic behavior for an ACBB. The characteristic distribution of kinematics and mechanics for an ACBB are calculated, which reveals that there is the correlation between dynamic behavior and working conditions in an ACBB. Clear contact characteristics always appear in the worst working condition. Based on the dynamic stability, the optimal design of structural parameters for an ACBB is outlined, which will prove helpful to achieve a better bearing performance.
