|
摘要
以某微车后桥主减速器主、被动齿轴承安装距引起后桥振动为研究对象,为了优化主、被动齿轴承安装距对振动噪声的影响和提高主、被动齿轴承使用寿命。通过三维建模和ADAMS动力学仿真,将不同安装距在不同转速下分别进行仿真分析,得到最佳安装距,并通过试验验证了在该安装距下,主减速器减振降噪得到很大的改善,而且轴承寿命也得到很大的提高,同时也为该微车主减速器的结构设计和减振降噪提供方法指导。
Taking the vibration of rear axle caused by bearing mounting distance of a mini car rear axle main reducer driving gear and driven gear as the research object,in order to optimize the impact of the bearing mounting distance of driving gear and driven gear on the vibration noise,and improve the service life of the bearing of the driving gear and driven gear. The different mounting distance at different speeds are analyzed by simulation respectively by 3D modeling and ADAMS dynamics simulation,the optimal installation distance is obtained,and through the test on the mounting distance,the vibration and noise reduction of the main reducer are greatly improved,and the bearing life is greatly improved. At the same time,it can provide a certain method guidance for the structure design and the vibration and noise of the main reducer of the mini car.
