基于高分子复合材料齿轮啮合传动过程的热力学分析和动力学分析,建立了其热力耦合模型,研究了齿轮本体温升和摩擦界面瞬态温升的变化规律。采用有限元软件LS-PrePost对齿轮进行摩擦热仿真分析,分析了影响分子复合材料齿轮啮合传动过程温升场分布的主要因素;并采用红外线热像仪对本体温升和瞬时温升进行实时测量。结果表明,摩擦因数越大,本体温升变化越显著,随着外载,G,的增大,接触界面瞬时温升变大,理论计算值与实测值基本吻合。
Based on the thermodynamics and dynamics analysis of polymer composite gear meshing transmission process, the coupling thermal-mechanical model is established, the changing rule of the gear body temperature rise and the transient temperature of friction interface is studied. The main factors influencing the temperature field distribution of molecular composite gear during gear meshing transmission are analyzed by using the finite element software LS-PrePost. The body temperature rise and instantaneous temperature rise are measured in real time by infrared thermograph. The results show that the greater the friction coefficient, the more significant the temperature rise of the body. With the increase of external ,G, the instantaneous temperature rise of the contact interface increases, and the theoretical calculation value is basically consistent with the measured value.
