摘要：
A three-dimensional nonlinear dynamic model of a double helical gear pair with 16-DOF was established taking teeth surface sliding friction, time-varying meshing stiffness, gear backlashes and gear mesh errors into account. The dynamic equations of the system were established with Newton Second Law. The tooth meshing force, tooth friction and friction torque were calculated with numerical integration according to the meshing characteristics of the double helical gear pair. The teeth surface friction coefficient was calculated with the model based on EHL. The effects of teeth surface friction on the dynamic behaviors of the system were analyzed. The results showed that the teeth surface sliding friction can lead to increase in vibration displacements in the direction perpendicular to the line of action and decrease in vibration along the line of action; the bifurcation of the system becomes blurred at higher meshing frequencies and the chaotic motion of the system appears earlier and infirmly due to the effect of teeth surface friction. The study was helpful for the further understanding the effect of teeth surface friction on periodic vibration and nonlinear vibration of double helical gear pairs. The results provided a technical basis for the design of double helical gear transmission. © 2016, Editorial Office of Journal of Vibration and Shock. All right reserved.
