Abstract: The effectiveness of mesh phasing to suppress certain orders of harmonic responses of RV reducer is investigated with Fourier series method. The lumped-parameter method is used to develop a transverse-torsional dynamic model, which considers key factors such as mesh stiffnesses of involute and cycloidal gears, bearing stiffnesses and support stiffnesses. The Fourier series method is used to solve dynamic response excited by the mesh stiffness. According to characteristics of the central components, each order of harmonic responses belongs to one of three typical types: rotational, translational and planetary component response modes. The typical response mode is related to mesh phasing factor. The law of mesh phasing is revealed by exploring the relationship between suppression of certain harmonic and mesh phasing factor, which is due to inherent symmetrical structure. Finally, the influence of the stiffness and torque on dynamic response is studied. The research provides some referential value for the reduction of vibration and dynamic design of RV reducer.

Keywords: RV reducer; dynamic response; mesh phasing; influence factor.
