The Kinematics Modeling and Analysis of the Series Mechanism with Oval Gear and Geneva

提出一种运动系数可调的槽轮机构,利用卵形齿轮机构作为槽轮机构的前置机构,将槽轮机构中的主动件与从动椭圆齿轮固连,实现槽轮的变速间歇运动.建立了串联机构的运动学模型,分析了槽轮作间歇运动的角速度和角加速度并可视化,最后推导出串联机构的运动系数计算公式.

In this paper, a geneva mechanism with the adjustable motion coefficient is presented, the oval gear mechanism is used as the front mechanism of the Geneva mechanism, and the driving part and the driven elliptical gear are fixedly connected to realize the intermittent motion of geneva wheel. The kinematic model of the series mechanism is established, and the angular velocity and angular acceleration of the intermittent motion of geneva wheel are analyzed and visualized. Finally, the calculation formula of the motion coefficient of the series mechanism is deduced.
