摘要：
In this paper, a method for the dynamic modification of tooth width is used to optimize the problem of uneven loading of helical gears. Considering the meshing error caused by gear manufacturing, installation, time-varying meshing stiffness, clearance, and shaft bending, the distributed meshing transverse-torsion-pendulum nonlinear dynamic model of a helical gear pair is established. A method to modify the tooth width of the helical gear pair is proposed to optimize the uniform load characteristics of the tooth surface. Through the research of dynamic tooth width modification, the optimal modification parameters are obtained so that the dynamic load distribution of the tooth surface is uniform and the load distribution centre is close to the centre of the tooth surface, which reduces the swing phenomenon. During experimental testing, the swing vibration response of the modified gear is reduced by a maximum of 26.15%, the dynamic load coefficient is reduced by a maximum of 20.84%, and the stress distribution on the tooth surface is uniform.
