| 摘要: |
| 为了降低人字齿轮传动的振动噪声,对其动态特性进行研究.在综合考虑轮齿刚度激励、误差激励和啮合冲击激励的基础上,应用集中参数法建立人字齿轮弯-扭-轴耦合的动力学模型.根据牛顿力学定律,推导出相应的运动微分方程.讨论了各种激励和轮齿修形对人字齿轮动态特性的影响.以一对人字齿轮为例进行动态试验,结果表明,修形前后齿轮箱的结构振动与理论分析结果相符合,验证了理论分析的正确性. |

| Abstract: |
| To reduce the vibration and noise of double helical gears transmissions,its dynamic behavior was studied.Considered the internal dynamic excitation produced by stiffness excitation,error excitation and mesh impact excitation,a bending-torsional-axial coupling dynamic model of double helical gears was established by the method of concentrated parameter.The dynamic equation of this system was deduced by the Newton method.The effect of excitations and tooth modification on dynamics behavior was discussed,and the corresponding conclusions were obtained.Finally,a test was carried out and the result agrees well with the theory analysis,which validates the correctness of the dynamic model. |
