Effect of Gear Installation Flatness in Main Reducer on Gear Mesh Vibration Based on <i>A</i><i>dams</i> Simulation

This paper takes spiral bevel gear installation planes of a main reducer in a rear axle of a certain car as the research object, using ug to establish three-dimensional model of the main reducer assembly, applies adams simulation and the quantitative and qualitative method to analyze the effect law of the spiral bevel gear installation flatness error on gear mesh vibration, obtains the reasonable area of gear installation flatness error , it provides the reference for parameter design and installation of the spiral bevel gear in the main reducer.
