| In this paper, based on the auto industry from China's national conditions and done a full investigation of the situation with domestic and foreign automobile final drive assembly industry is currently, researching the main gear assembly of the rear axle gasket assembly technology and optional features of the simulation analysis and optimized.The article is based on the structure of the main gear assembly, Analysis the most important points process of the rear axle assembly: installation and bearing preload adjustment bevel gear meshing method to determine the bearing preload assembly process requires control of the target variable - - preload torque, To find ways improve the quality of assembly --- by adjusting the bearing preload spacer thickness control, And ultimately comes down to use the finite element method to analyze the problem of gasket thickness.Through the main gear assembly and explore the preload force, there are two key factors come to affect the final drive assembly quality and life: First, the size of the force with active bevel gear (the main cone) components bearing preload. if the preload too much, it will accelerate bearing wear; the other hand, it will generate noise and vibration. Second, the gear gap of main final drive, driven spiral bevel. if the gap is too large, it will produce noise and vibration; but the contrary, it will increase gear wear, broken teeth or even killed there gear phenomenon.These factors can be adjusted with control the thickness of the main gear gasket. Therefore, this study research the main gear assembly process and to adjust the thickness of the gasket and tightening the link between force and torque, and ultimately, improve the quality of the main gear assembly in theory, This combination of theory and design for the theoretical analysis provides a method and basis, the main gearbox gasket optional improvements to optimize the accumulation of experience. |
