一种长短轴半径无级可调的椭圆规研制

A Kind of Ellipsograph Which's Long and Short Shaft's Radius' Length can be Ajusted Steplessly

目前的椭圆规结构复杂,长短轴长度调整及携带很不方便。基于一椭圆参数方程,研制了基于锥齿轮传动的长短轴半径无级可调的椭圆规。实际应用表明,该仪器结构简单,便于携带,操作方便,长短轴半径无级可调,可绘制不同尺寸的椭圆。

The structure of current ellipsographs is complicated, and it is difficult to adjust the length of long and short shaft’ s radius and inconvenient to carry. A new kind of ellipsograph developed based on a parametric equation of ellipse.The ellipsograph’ s dirive system is composed of the bevel gears, and its length of long and short shaft’s radius are steplessly adjustable. The actual practice shows that the structure of the ellipsograph is simple, and it is portable and convenient. The length of long and shot shaft’ s radius can be steplessly ajusted. So the different size of ellipse can be drawn by it .
