Abstract :
Double helical gear transmission is a very important transmission component. A lot of dynamic models of spur and helical gears for studying dynamic characteristics have been put forward, but the studies on double helical gears are scarce. To study the nonlinear dynamic characteristics of the double helical gear system, the nonlinear dynamic model of double helical gear system was established. Then the dimensionless dynamic model was summarized. Through numerical computation, the nonlinear dynamic characteristic was revealed in some aspect. The vibration amplitude of gear is smaller than the vibration amplitude of pinion at the same direction and the vibration amplitude of the same component at direction is larger than the amplitude of gear at direction. Through the numerical method, we find that there is a plenty of nonlinear dynamic characteristics in the double helical gear system, and thus more research is needed.
