Computer Simulation for Dynamic Meshing Force of Involute Gears

In order to obtain the data of dynamic meshing force of involute gears in meshing transmission process , computer simulation of involute gears meshing transmission simulation is proposed on the basis of MSC-ADAMS software. Considering the high speed and large torque of the gears transmission as well as the variation of meshing point of involute gears in the transmission process, the formula for the calculation of the contact stiffness based on Hertz elastic contact theory was devised and a simulation model was built for the meshing process of involute gears. The meshing process of a pair of gears was simulated in three running situations and their dynamic meshing force responses were calculated. The results showed that the gear meshing forces in the meshing process of involute gears were obviously dynamic. The dynamic loads were not symmetric forces. Moreover, the dynamic forces and their time ratio in a running loop increased with the rise of the rotational velocity of the gears.
