PARABOLIC SNAIL AND OTHER SIMILAR CURVES DRAWN BY A MECHANISM

Abstract

An Artobolevskii mechanism that generates the parabolic snail is being studied. The structural analysis of the mechanism proved to be difficult, finally establishing that one element and two kinematic couples with which it binds are structurally parasitic. By the contour method the calculation relations were established obtaining the desired curve. The mechanism for different values of the angles between the sides considered initially constant was further studied, obtaining a range of curves generated by this mechanism. The positions of the straight segments (horizontal and vertical) which are guides of the sliders have also changed.
