It was also investigated by Steiner in 1856 and is sometimes called Steiner's hypocycloid. |
An astroid is a specialized case of the general hypocycloid family of curves. |
The present invention relates to a hypocycloid gear assembly used in internal combustion engines. |
The piece is based on a set of parametric equations that create a deltoid, a type of hypocycloid which looks like a triangle with concave sides. |
With this cinematic solution the tip of the tool describes a hypocycloid curve. |
If the describing circle is half the diameter of the pitch circle, the hypocycloid is a radial straight line. |
