The effect of various forms of damping on the vibration of gear body is studied.Firstly

the periodic meshing force of gear drive is obtained by the FEA software ANSYS.Secondly

the gear model is simplified

the meshing force is added to the gear body and the vibration before and after damping are compared.The result shows that

the single-web gear with constrained damping layer is better than the one with non-constrained damping layer

for constrained damping layer can effectively decrease web vibration and reduce noise.
