Abstract

L'invention porte sur un dispositif de transporteur configuré de telle sorte que, afin de réduire la pulsation de la vitesse de déplacement horizontal d'une chaîne du dispositif de transporteur, la chaîne est entraînée par un pignon. Le dispositif de transporteur comporte un guide pour guider des broches de la chaîne. La surface de guidage du guide guide les broches le long de la trajectoire de l'intersection, entre une ligne radiale traversant le centre d'une rainure de pignon et un arc circulaire présentant un rayon qui est la distance entre les première et seconde broches d'un certain maillon. A la partie d'entrée du guide, une broche est reçue à une position sur le cercle primitif du pignon, après quoi la broche est déplacée vers une position à l'extérieur du cercle primitif dans la direction radiale, de façon à éliminer un balancement d'un pas et une pulsation de la chaîne. La pulsation du dispositif de transporteur utilisant la chaîne peut être éliminée.
