In this paper, a purely axial torsional—translational model of helical planetary gear set is proposed. The model is acceptable for the research of planetary gear transmission whose ratio of radial support stiffness to mesh stiffness is greater than 10. The gear-shaft bodies were modeled as rigid bodies and all of the planets were uniformly distributed. Compared with previous planetary gear models, presented model greatly reduced the number of degrees of freedom. All vibration modes were classified into one of two types: overall modes and planet modes. The properties of these mode types were presented.
