| 由于制造误差与装配误差难以避免，减速器在运行过程中通常会存在振动、噪声等问题，为保证设备工作性能，减速器应具有高速、稳定、低噪声、长寿命等特性，以AGV驱动轮行星减速器为例对降噪问题进行研究，提出了一种基于弹性流体动力学润滑(EHL)的微观修形方法：通过数学模型推导考虑弹流润滑摩擦-动力学耦合的齿轮微观修形量计算式，利用ROMAX和Hypermesh对减速器进行参数化建模，联合LMS Virtual. Lab对修形后的传动性能和声压值进行仿真分析，仿真结果表明，EHL微观修形后的接触应力、传动误差和声压值均有所降低，并进行接触斑点对比试验和样机噪声测试，实验结果证明EHL微观修形能够有效降低噪声。 |

| As manufacturing errors and assembly errors are difficult to avoid, the reducer usually has vibration, noise and other problems during operation. In order to ensure the working performance of the equipment, the reducer should have the characteristics of high speed, stability, low noise and long life. Taking the AGV drive wheel planetary reducer as an example, the noise reduction problem is studied. A microscopic modification method based on elastohydrodynamic lubrication (EHL) is proposed: A calculation formula for the micro-shape modification of the gear considering the friction-dynamic coupling of elastohydrodynamic lubrication was derived through the mathematical model. The parametric modeling of the reducer was carried out by using ROMAX and Hypermesh, and the simulation analysis of the transmission performance and sound pressure value after the modification was carried out in conjunction with LMS Virtual.Lab. The contact stress, transmission error and sound pressure are reduced after EHL micromodification, and the contact spot calibration test and prototype noise test are carried out. The experimental results show that EHL micromodification can effectively reduce noise. |
