Maquette cinématique
Kinematic model
Il y a quelques années, je devais expliquer les principes de la transformation des mouvements de la rotation vers la translation... Une petite maquette valant mieux qu'un long discours, j'ai construit le montage suivant, montrant quelques unes des solutions simples possibles.
A few years ago, I had to explain the principles of the transformation of rotational movements into translation movements... A small model being better than a long speech, I built the following assembly, showing some of the possible solutions.
Transmission par roue/chaîne ; pignon/crémaillère ; galet / came parallèle ; galet / came normale ; vis / écrou ; bielle / manivelle
Chain & sprockets / pinion & toothed rack / screw rod & nut / various cams / cranck...
|
Each movement is controlled independently by a Power Drive Unit supplied with a transformer hidden in the base. |
