This paper puts forward a new type of gear anti-backlash drive mechanism, in view of traditional’ manufacturing is difficult and production cost is high. This mechanism uses the structure of a pair of worm gears which are against each other and double gears to eliminate the back clearance volume. The dynamic model of the mechanism in this paper is established by the method of lumped mass, and the model’s numerical solution is solved by fourth-order Runge-Kutta. Then the nonlinear dynamic characteristics of system are simulated and analyzed. The studies show that this mechanism whose backlash has been eliminated has a good dynamic characteristics, and increasing system’s meshing damping can shorten the vibration attenuation time and improving the average meshing stiffness can reduce vibration amplitude of the system. |
