| Abstract: | Considering the torsional vibration only, a dynamic model of the RV-6AⅡ reducer is formulated by lumped-parameter method. Furthermore, the natural frequency of first order is evaluated. It is revealed that the stiffness of the bearings in the carrier gives the most great influence upon the natural frequency. Finally, the established model is verified by an experiment. |
