Abstract
Gear transmission system is widely used in mechanical systems, such as joints in manipulator system. However, the vibration and noise caused by the backlash in gear pair are significant to the manipulator system. The effects of backlash on vibration characteristics the gear-rotor system are investigated numerically. First, the dynamic model of gear system is established considering the variable meshing stiffness and damping. Then, the dimensionless method is used and the dimensionless differential equations are obtained and then calculated numerically. Finally, a numerical example is presented to study the effects of backlash on the vibration of the gear-rotor system. The results indicate that the vibration characteristics of gear mechanism with backlash are significant, which will provide the basis for the design and control of manipulator system.
