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。
In order to optimize the main and passive gear bearing installation distance vibration noise and improve the service life of the main and passive gear bearings, the main and passive gear bearing installation of the rear derailleur of the rear axle of a micro-vehicle is taken as the research object. Through three-dimensional modeling and ADAMS dynamic simulation, the different installation distance at different speeds were simulated and analyzed respectively, and the optimal installation distance was obtained. It was verified through experiments that under the installation distance, the main reducer vibration and noise reduction was very large , And the bearing life is also greatly improved. At the same time, it also provides the method guidance for structural design and vibration reduction and noise reduction of the micro-car reducer.
