Abstract

A rotor - bearing model of 5 degrees of freedom was established by finite element method, and a gear pair meshing model of 5 degrees of freedom was established by Newton’s second law. By introducing the azimuth, the gear rotor system could be designed with the gear pair arranging at will. Then through the transformation of coordinate system, the coordinate system of rotor-bearing model and gear pair model were unified, and the two were coupled together, and a complete gear-rotor model with uniform coordinate system was established.
