3D model description

Après les engrenages droits et hélicoïdaux, je voulais faire un engrenage paradoxal.
Voici le résultat : ça fonctionne.

C'est étonnant comment les roues tournent dans le même sens.
Mais c'est possible.
C'est le CNAM à PARIS ( Conservatoire national des Arts et Métiers) qui a fabriqué le premier un engrenage à deux dents, nommé paradoxal.
J'ai voulu faire quatre dents et ça marche aussi.
sympa à faire tourner, aucune difficulté pour imprimer, veiller simplement à bien ajuster les pignons sur les axes.

After the spur and helical gears, I wanted to make a paradoxical gear .
The result : it works .
It is amazing how the wheels turn in the same direction .
But it is possible.
This is the CNAM to PARIS that manufactured the first one gear with two teeth , called paradoxical.
I wanted to make four teeth and it works well.
nice to turn , no problem to print , simply ensure to properly adjust the gears on the axes.
