| 摘要: |
| 分析了偏心链轮传动机构的运动学与动力学特性，确定了偏心链轮的振动方程、速度与加速度计算方程和从动轮的运动规律。在动力学分析中，讨论了链条与链轮的啮入冲击、附加载荷、共振频率及铰链的爬高与跳齿的计算。结果认为，偏心链轮传动的齿面磨损量大，易跳齿、只宜用于轻负荷的操纵机构；瞬时传动比is的变化范围较大；链条对轴的作用力为周期性的脉动载荷，其振动和跳齿问题限制了该机构的传动比，其在削皮机中能不否应用，取决于刀具的转速。 |

| The characteristic analysis on transmission of cam chain wheel gearing |
|
|
| Abstract: |
| This article analyzed the kinematic and dynamic characteristics of cam chain wheel gearing,and put forward the vibrancy equation,speed equation and acceleration equation of cam chain wheel.By discussing the gnawing impact,affixation load,synchronic vibration and tooth-leap calculation between chain and wheel,the study showed that the tooth surface wear hard,tear hard and the tooth leap hard.So it is suitable for light load gearing.The force to shaft is seasonal load,then,it conduces libration and tooth-leap,so the driving ratio is limited. |
