摘要

为了研究齿面微观形貌对齿轮运动稳定性的影响,引入分形理论,通过真实齿面的特征数据,实现圆柱直齿轮齿面形貌的模拟;借助W-M函数、M-B分形接触模型和Hertz接触公式,建立考虑齿面凹凸不平的刚度和阻尼数学模型;分析不同加工方法对齿面法向接触刚度和阻尼的影响,运用MATLAB和ADAMS研究齿面法向阻尼对齿轮啮合振动特性影响的规律。结果表明,齿面微观形貌影响齿轮运动平稳性;加工方法影响齿轮的啮合刚度和阻尼;电化学光整加工与磨削和铣削加工相比,法向接触阻尼更大,更有助于减少齿轮振动,提高齿轮运动稳定性。

Abstract

In order to study the influence of tooth surface microstructure on gear motion stability,the fractal theory is introduced to realize the simulation of the shape of the cylindrical straight gear tooth surface through the characteristic data of the real tooth surface. With the help of W-M function,M-B fractal contact model and Hertz contact formula,the stiffness and damped mathematical model considering the uneven surface of gear surface is established. The influence of different machining methods on the normal contact stiffness and damping of the tooth surface is analyzed,MATLAB and ADAMS are used to study the influence of normal contact stiffness and damping of tooth surface on the vibration characteristics of gear meshing. The results show that the microstructure of tooth surface affects the stability of gear motion. The machining method affects the meshing stiffness and damping of gears. Compared with grinding and milling,the normal contact damping of electrochemical finishing method is more larger,the method is more effective to reduce the vibration of gears and improve the stability of gear.
