【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。
[Abstract]:The vibration of the rear axle caused by the installation distance of the main reducer of the rear axle of a micro vehicle was studied. In order to optimize the vibration noise of the bearing the influence of the installation distance of the passive tooth bearing on the vibration noise and the service life of the active and passive tooth bearing were improved. Through 3D modeling and ADAMS dynamic simulation, the different installation distance is simulated and analyzed separately at different rotational speeds, and the optimum installation distance is obtained, and the test results show that the main reducer vibration and noise reduction is greatly improved under the installation distance. The bearing life is also greatly improved, and it also provides guidance for the structural design and vibration reduction and noise reduction of the micro-vehicle reducer.
