摘要
在许多机械设备中，尤其是自动和半自动机中，由于生产工艺的需求，往往需要机构实现周期性的转位、分度以及作带有瞬间停歇或有停歇区的断续性运动。
总的来说，间歇运动机构根据其不同的结构特征和运动原理，可以分为两大类：一类是实现步进运动的间歇运动机构，如棘轮机构、槽轮机构、不完全齿轮机构、共轭盘形分度凸轮机构等；另一类是实现瞬间停歇或停歇区的间歇运动机构，如凸轮-连杆组合机构以及差动链轮机构。
由于间歇机构传动的间歇特性以及设计难度较大，所以现实生活中，对于间歇机构运动分析的试验平台还是比较少见的，本文着重对常见的几种可以实现步进运动的间歇机构进行设计，通过理论初设计时确定机构的动停比，在试验台上安装相应传感器，对运动的间歇机构进行数据的采集，绘制出间歇机构的运动曲线，对机构进行运动的分析，确定机构在理想工况下的传动特性，从而对后期机构的矫正与优化提供一定的帮助。

Abstract
In many machinery and equipment，Especially in automatic and semi-automatic machines , Due to the demand of the production process, Often requires agencies to achieve a cyclical translocation, indexing and with instantaneous stop or stop intermittent motion.
Overall, Intermittent mechanism can be divided into two categories according to their different structural characteristics and movement principle, One is stepping movement intermittent motion mechanism, such as Ratchet mechanism, Geneva mechanism, incomplete gear mechanism, conjugated disc-shaped indexing cam mechanism and so on; The other is instantly stop or rest area intermittent motion mechanism, such as Cam - connecting rod combination mechanism and differential sprocket mechanism.
Due to the intermittent transmission characteristics of intermittent institutions as well as design more difficult,, in real life, the test platform for intermittent motion analysis is still relatively rare. This article focuses on several common stepper motion can be achieved intermittent  do a parametric design. Determined by the theory of the early design agency of the  Proportion of movement and rest. Sensor installed on the test stand, collect the data of the Intermittent movement mechanism, Measuring the angular displacement of its movement, the angular velocity, Analysis of the motion of the institutions, Determining mechanism in the transmission characteristics of the ideal conditions, Correction and optimization of the late institutions to provide some help.
Key words:Intermittent mechanism;Sensor;stepper motion；Test bench
