Dynamic simulation of meshing force in broken tooth involute gear meshing process based on ADAMS

In order to obtain the changing pattern of meshing force for broken tooth gear meshing and evaluate quantitatively the battle damage degree of involute gear transmission system, a computation method based on dynamic simulation was proposed. The 3D model of broken gear is established through Pro/E and the dynamic model of involute gear transmission system is established by using the dynamic simulation software ADAMS based on the Hertz contact theory. The model of the gear with different number and position of broken tooth is established when the coincidence degree is known. The simulation results show the meshing force fluctuation frequency and fluctuation amplitude of the gear transmission system show significant differences when the broken tooth number is different or the tooth breaking in different position, and the broken tooth leads the meshing force appears the lag phenomenon.
