Natural Frequency Analysis based on RV Reducer Theory Model
Abstract
In order to analyze the resonance response of RV gear reducer system，the natural frequency of RV gear reducer system should be determined first. Taking RV-320E gear reducer as the research object and considering tangential degrees of freedom of crank shaft and cycloid wheel rotation motion，the 16 degrees of freedom dynamic model of RV gear reducer is established by centralized mass method. The dynamics differential equation of the system is established by Newton's second law and the differential equation of fixed axis rotation，and the natural frequency of the system is calculated. The influence of the material properties of the parts on the first-order natural frequency is analyzed and the influence graph is drawn.
