Abstract: Taking the tooth stiffness distribution, transmission error distribution, translational stiffness, twist stiffness and the center of stiffness into account, a dynamic model for general helical gear pairs is developed. Then the rotors and bearing flexibility are introduced to the model, and a finite element model for the rotor system of helical gear is determined. Finally, dynamic responses are analyzed based on the gear rotor systems. The results show that the model is effective and accurate for general helical gear rotor systems. Moreover, through studying the fast Fourier transform of the dynamic mesh force, the 1×mesh frequencies of the system has a main influence on the response the rotor system.

Key words: helical gear, integral model, load distribution, rotor system, vibration characteristic
