Finite Element Modes Analysis of Involute Planetary Gear in RV Reducer
Paper built the solid model of RV involute planetary gear with three dimensional modeling software Pro/E, dumped this model into ANSYS with IGES middle exchange file, define the three crankshaft solid connect with the three involute gear, carried on the modal analysis with finite element method, obtained the natural frequency and the vibration mode,. Results put out the danger frequency focus on 3645Hz, 8610Hz ,16729etc., then paper examined the different natural frequency and contrast them with the natural frequency of whole RV reducer, results shows that when the input speed of reducer turning at 1500r/min, for the three involute gear it’s not easy to cause resonance, but being the incentive frequency is 525Hz, it should to pay attention to avoid 451.63Hz, which was a key natural frequency of RV reducer, finally paper laid the system's dynamic response calculation and analysis of RV reducer.
