Design and experimental study of the rolling-enhanced acoustic system for gear tooth surface

Parameters of gear flanks, such as roughness, hardness, and residual stress, impact their working performance. Therefore, it is essential to optimize these parameters for increasing gears’ life. Thus, this study combined the meshing theory ultrasonic surface rolling technology presented an innovative design realize burnishing. First, dimensions burnishing device with two nodes integrated a at bottom were calculated using frequency equations by numerical method. Second, correctness calculating results was verified simulations experiments. Third, influence ratio between width diameter on acoustic system studied. Finally, experimental platform rolling-enhanced tooth built successfully. A series experiments conducted, showed that roughness can be reduced 76% most, hardness stress increased 53% 415%, respectively. provided new machine complicated surfaces flanks.
