轴承游隙的大小决定了轴承的旋转精度和承载能力,通过对游隙值的控制,可以达到降低传动系统振动和噪声的目的。文章针对ZUA200型城际动车组,提出了通用性齿轮箱轴承游隙调整工装设计方案,并使用UG软件对工装进行三维建模,同时利用软件高级仿真功能对该工装进行有限元分析,得到了工装的应力应变云图,验证了工装的合理性。 Bearing clearance determines the size of the bearing rotation accuracy and bearing capacity, by controlling the clearance value, you can achieve the purpose of reducing transmission system vibration and noise. In this paper, aiming at the ZUA200 intercity EMU, a universal gearbox bearing clearance adjustment tooling design is proposed, and the UG software is used to make 3D modeling of the tooling. At the same time, the tooling is analyzed by finite element method Tooling stress and strain cloud map, verify the rationality of tooling.
