为了探究半球型锥齿轮参数变化对其系统动态特性的影响,基于集中质量法建立了该半球型锥齿轮副的动力学模型;基于高质量的六面体网格模型,采用刚柔耦合柔体动力学仿真分析了半球型锥齿轮的动态传动性能;分析了半球型锥齿轮尺寸、轴交角等参数变化对系统运动状态的影响。仿真结果表明,系统在不同参数条件下会导致传动准确性、平稳性和强度有规律的变化且互为负相关;半球型锥齿轮在分度圆直径为65 mm、相交轴角度为120°时综合性能最优。柔体动力学仿真分析为研究半球型锥齿轮的设计、制造以及实现齿轮传动最优化,提供了重要的参考价值。
In order to explore the influence of the variation of hemispherical bevel gear parameters on the dynamic characteristics of the system, a dynamic model of the hemispherical bevel gear pair is established based on the lumped mass method. Based on high-quality hexahedral mesh model, the dynamic transmission performance of hemispherical bevel gears is analyzed by rigid-flexible coupling flexible body dynamics simulation. The influence of parameters such as the size of hemispherical bevel gears and the shaft angle on the motion state of the system is analyzed. The simulation results show that the transmission accuracy, stability and strength of the system change regularly and are negatively correlated with each other under different parameters. The comprehensive performance of hemispherical bevel gears is the best when the diameter of indexing circle is 65 mm and the angle of intersecting shaft is 120°. The flexible multi-body dynamics simulation analysis provides an important reference for the model design, processing and manufacturing of hemispherical bevel gears.
