Abstract:

The elastic dynamic model of gear is established according to the working conditions of gear, and the elastic dynamic characteristics are analysed. The shaft is treated as elastic support. Considering the influence of supporting shaft on the gear body vibration, the formula of the spring stiffness is deduced. In the elastic supporting condition, considering the influence of the elastic plate on the meshing tooth response, the dynamic model of gear supporting system and the response analytic model of meshing tooth are established, and the natural characteristics of the gear supporting system arc studied and compared with the experimental results. The dynamical response of the meshing tooth is calculated and simulated.  This research indicates that the analysis of the gear supporting system using elastic supporting is valid, and provides methods Ior the calculation of dynamic load and the dynamic design oI the gear body, as well as the accurate dynamical study of gear transmission system.
