As a key component to increase torque and reduce rotation speed in automobile transmission system, the quality of final drive assembly is related to the working performance of the whole transmission system. As the core component of the rear drive axle of an automobile, the main reducer of the automobile bears the functions of decelerating and increasing the driving torque. Its quality directly affects the safety and comfort of the automobile. The transmission stability and transmission noise of the main drive bevel gear of the main reducer are one of the important factors that affect the performance parameters of the whole system. The order analysis can transform the equal time sampling of vibration signal into equal angle sampling, and transform the non-stationary signal in time domain into the stationary signal in angle domain. Then, the frequency of rotation speed and the position of each harmonic can be determined by spectrum analysis. Starting from the function and structure of the main reducer of the automobile rear axle, this paper explains the necessity of analyzing its vibration signal, and expounds the mechanism and source of the vibration of the main reducer.
