【Abstract】 The noise of electric vehicle reducer mainly comes from the vibration of gear pair, and the vibration of gear pair is closely related to the quality of gear processing. The machining quality of the gears affects the noise and efficiency of the gear meshing. By using correlation analysis, sensitivity analysis and other methods, the influence of gear processing quality on the noise and efficiency of gear meshing was studied by using manufacturing deviations such as tooth surface waviness, profile form deviation, profile slope deviation, helix form deviation and helix form deviation to simulate the processing quality difference in actual production. The results show that, in general, the profile form deviation and profile slope deviation of active gear and passive gear have a great influence on noise and efficiency. The analysis results reveal the internal relationship between machining quality and gear noise efficiency, and provide scientific basis for optimizing gear design and machining technology.更多还原
