摘  要椭圆是最常见的几何图形之一，在工程和数学上都有着广泛的应用,但手工作图颇为困难,而且不容易准确。目前的市场上的手工绘图工具基本只能绘制直线和圆，对于椭圆的绘制，虽然多年来国内外有不少人从事这方面的研究，但至今还没有一种非常理想的椭圆绘图工具。本文依据行星齿轮机构的运动原理，设计了该椭圆规机构。本设计具有操作便捷,作图精确的优点,具有广阔的市场前景和应用范围。在确定设计方案后，本课题重点对椭圆规的齿轮、旋转轴、连接杆等重要零件利用三维绘图软件进行设计和装配，并将设计好的椭圆规机构导入仿真软件进行运动学分析。

Oval design regulations

Abstract The ellipse is the most common geometries in engineering and mathematics have a wide range of applications, but the manual drawing quite difficult, but not easy and accurate。 Hand drawing tools currently on the market basically only draw lines and circles, for drawing ellipses, although there are many people at home and abroad for many years engaged in research in this area, but has not yet been an ideal ellipse drawing tools。 In this paper, based on the principle of movement of the planetary gear mechanism, the design of the regulatory agency ellipse。 This design has the easy operation, accurate mapping of the advantages of having a broad range of applications and market prospects。 In determining the design, the emphasis on the important parts of this task oval gear regulations, the rotating shaft, connecting rods, etc。 using three-dimensional graphics software for the design and assembly, and the regulatory mechanism designed oval import simulation software for kinematic analysis。
