| 中文摘要: |
| 设计了一种剪切型粘滞阻尼器结构，研究其对斜齿圆柱齿轮轴系的振动控制规律。对该剪切型粘滞阻尼器的结构特点和减振耗能特性进行了介绍，在此基础上，搭建了一级斜齿圆柱齿轮传动实验台，实验研究了粘滞阻尼器对斜齿圆柱齿轮轴系的减振特性。实验结果表明，在较宽的转速范围区间，粘滞阻尼器可以同时抑制斜齿圆柱齿轮轴系水平和轴向的振动，有效改善齿轮副的啮合状态，衰减其冲击振动，减小振动激励。粘滞阻尼器可以大幅抑制斜齿圆柱齿轮系统啮合频率的高次谐波成分的振动。阻尼器不同安装位置的振动数据表明，在主、从动轴上同时安装粘滞阻尼器的减振效果要优于单轴安装阻尼器，因此，在实际应用中，要尽可能将粘滞阻尼器安装于振动较大的轴系，以获得理想的减振效果。 |

| A shear viscous damper structure is designed to study the vibration control law of helical cylindrical gear shafts. The structural characteristics and energy dissipation characteristics of the shear viscous damper are introduced. On this basis, a first-grade helical cylindrical gear transmission test-bed is built, and the vibration reduction characteristics of helical cylindrical gear shafts with viscous damper are experimentally studied. The experimental results show that the viscous damper can suppress the horizontal and axial vibration of helical cylindrical gear shafts at the same time in a wide speed range, effectively improve the engaging status of the gear pair, attenuate the impact vibration and reduce the vibration excitation. This viscous damper can greatly reduce the vibration of high-order harmonic components of the meshing frequency of helical cylindrical gear system. The vibration data of different installation positions of the damper show that the damping effect of installing viscous dampers on the driving and driven shafts at the same time is better than that of the single shaft’s damper installation. Therefore, in practical application, the viscous damper should be installed on the shaft with larger vibration as much as possible to obtain the ideal vibration reduction effect. |
