矿用减速器运行过程中,齿面偏载会削弱齿轮啮合性能,增加齿轮系统的振动与噪声,需对其进行优化。首先运用Romax软件对矿用减速器齿轮系统进行啮合性能分析。再以齿轮传动误差波动最小化为目标,以齿轮齿廓、齿向修形参数为设计变量,运用遗传算法对齿轮副齿面进行优化。通过分析各设计变量对齿轮传动误差波动的影响,得到了最佳设计变量组合。然后对齿轮副齿面进行二次优化,获得了最佳修形优化方案。最后利用齿轮接触分析验证优化结果的正确性。结果表明:遗传算法优化得到的修形齿面可以有效减小齿轮传动误差波动量,改善齿面载荷分布,提高齿轮啮合性能。
During the operation of mine retarder, the tooth surface partial load will weaken the gear meshing performance and increase the vibration and noise of the gear system, which needs to be optimized. First, using Romax software to analyze the meshing performance of gearboxes for mining retarder. And then the gear transmission error minimization is the goal. Taking the gear tooth profile and tooth orientation modification parameters as the design variables, the gear tooth flank is optimized by genetic algorithm. By analyzing the influence of each design variable on gear transmission error, the best combination of design variables is obtained. Then, the gear tooth flank is optimized for the second time, and the optimal solution is obtained. Finally, the correctness of the optimization results is verified by using gear contact analysis. The results show that the modified tooth surface optimized by genetic algorithm can effectively reduce the fluctuation of gear transmission error, improve the tooth load distribution and improve the gear meshing performance.
