Two dynamic models of meshing contact in gear transmission are established. The transient dynamic characteristics of the gear transmission along line of action were analyzed based on deformable-body model and discrete parameter model. The curves on the displacement, the speed and the meshing force of the gear tooth meshing node with the change of time were gotten. Dynamic transmission error curves and teeth loads were computed within a wide range of rotational speed for different torques and working conditions with and without friction force. The results of the dynamic transmission error and dynamic teeth loads are validated by comparing the calculating results with that of the former experimental data. The research provides basic data for analyzing the gear impact and predicting the fatigue life of gear tooth, and it is also beneficial for the optimum design of gear parameters and the understanding of the dynamic phenomenon of gear meshing impact.
