摘要
针对齿轮传动中的振动和噪声问题,以Masta为仿真分析平台,通过对某变速箱主减速齿轮修形的仿真计算,得到了齿顶修缘量、齿形和齿向鼓形量等修形参数的变化对齿轮传动特性的影响规律。在对齿轮传动误差和齿面最大接触应力变化规律研究的基础上,选取了目标机型主减速齿轮的最佳修形参数。噪声试验结果表明,变速箱主减速齿轮修形后,齿轮啸叫得到了明显改善。
Focusing on the vibration and noise of gear transmission,taking Masta software as the analysis platform,by simulating and computing the modification of main reduction gear of a transmission,the effect relations between change of modification parameters such as tip relief,barreling relief and crowning relief with characteristic of gear transmission is obtained.The optimum modification parameters are selected based on the study of the law of gear transmission error and max contact pressure.Noise test result shows that the squeal of the transmission is reduced effectively after gear modification.
