Abstract

To make the gear better adapt to the high temperature environment, the effects of tooth surface friction and thermal deformation on the dynamic characteristics of the gear were studied. First, based on the basic theory of gear nonlinear dynamics, the backlash model is established considering the effects of thermal deformation. Then, an improved multi-degree-of-freedom nonlinear dynamic model of gears is established taking into account the effects of thermal deformation and friction. The effect of tooth surface friction and thermal deformation on the system motion state is analyzed. Finally, to better analyze the relationship between impact vibration and transmission efficiency, the percussion vibration index is introduced. Compared with the existing research, a gear multi-degree-of-freedom dynamic model is established by considering the influence of tooth surface friction and thermal deformation. The percussion vibration index is introduced as an indicator of gear running health. The research result can provide reference for the optimization and cooling of the gear transmission system.

考虑齿面摩擦和热变形的齿轮传动系统非线性动力学分析

为了使齿轮更好地适应高温环境，研究了齿面摩擦和热变形对齿轮动态特性的影响。首先，基于齿轮非线性动力学基本理论，建立了考虑热变形影响的齿隙模型;然后，考虑热变形和摩擦的影响，建立了改进的齿轮多自由度非线性动力学模型。分析了齿面摩擦和热变形对系统运动状态的影响。最后，为了更好地分析冲击振动与传动效率之间的关系，引入了冲击振动指标。在现有研究的基础上，建立了考虑齿面摩擦和热变形影响的齿轮多自由度动力学模型。介绍了冲击振动指标作为齿轮运行健康度的指标。研究结果可为齿轮传动系统的优化和冷却提供参考。
