【摘要】：工程实际中的很多场合,都需要用到往复转动。随着现代工业自动化水平的提高以及产品品种多样化发展的趋势,对实现往复运动的机构提出了新的要求。首先要求其自动化程度高便于控制,同时要求往复运动的速度和动程均可控以适应产品多样化的需要。文章内容主要有如下三个部分：第一部分,提出了采用双伺服驱动差动轮系将单向回转运动合成为可控往复输出运动,文中通过理论推导和运动仿真证明了其可行性,并在此基础上提出三种可实现方案,对应推导出了三种方案的等效转动惯量的计算式,为在工程实际中的具体应用选择何种方案提供了参考。第二部分,对非圆行星轮系和非圆差动轮系将电机的单向回转输入转化为往复转动输出进行了相关研究,提出了非圆齿轮的节曲线的设计方法并给出了几个非圆齿轮节曲线设计的相关实例。第三部分,将具有电子凸轮功能的伺服驱动轮系应用于工程实际中,同时为了使其具有更好的动态性能,对电子凸轮曲线进行了优化设计,并进一步对差动轮系伺服电机的驱动方式进行选择,采用优化设计的方法得出伺服电机的输入曲线,并使其具有较好的动态性能。
[Abstract]:In engineering practice, many occasions need to use reciprocating rotation. With the improvement of modern industrial automation level and the trend of diversification of product varieties, A new requirement is put forward for the mechanism to realize reciprocating motion. Firstly, it is required that its high degree of automation be easy to control, and at the same time, the speed and range of reciprocating motion can be controlled to meet the needs of diversification of products. The main contents of the article are as follows:. In the first part, the unidirectional rotary motion is synthesized into controllable reciprocating output motion by double servo drive differential gear train. The feasibility is proved by theoretical derivation and motion simulation. On the basis of this, three feasible schemes are put forward. The equivalent moment of inertia of the three schemes is derived, which provides a reference for the practical application of the three schemes. In the second part, the non-circular planetary gear train and the non-circular differential gear train are studied to transform the one-way rotary input of the motor into the reciprocating output. The design method of pitch curve of non-circular gear is put forward and some examples of non-circular gear pitch curve design are given. In the third part, the servo driving gear train with electronic cam function is applied to engineering practice, and in order to make it have better dynamic performance, the curve of electronic cam is optimized. Furthermore, the drive mode of the servo motor of differential gear train is selected, and the input curve of the servo motor is obtained by using the method of optimization design, and the servo motor has better dynamic performance.
