Abstract

L'invention concerne un mécanisme de conversion de mouvement, plus précisément un mécanisme de transmission mécanique qui utilise une combinaison de crémaillères et d'éléments d'engrenage composites pour convertir un mouvement linéaire de va-et-vient et une oscillation en une rotation unidirectionnelle continue. Le mécanisme de conversion de mouvement comprend : un cadre d'engrenage (1), une crémaillère (2), des éléments d'engrenage avant et arrière (3 et 4), un arbre (5), un composant de limitation de cadre d'engrenage (601), un bâti de machine (7) et un composant de limitation de crémaillère (602). Les éléments d'engrenage avant et arrière sont respectivement reliés en parallèle à l'arbre par le biais de paliers unidirectionnels. Les deux paliers unidirectionnels ont une même direction de blocage de la rotation. Le cadre d'engrenage est formé en reliant de manière fixe des crémaillères gauche et droite (101 et 102) disposées de chaque côté. Les crémaillères gauche et droite sont décalées l'une par rapport à l'autre à des positions dans la direction axiale de l'arbre et correspondent respectivement aux positions des éléments d'engrenage avant et arrière montés sur l'arbre. Une direction de non-mouvement du cadre d'engrenage est limitée à l'intérieur d'un composant de positionnement de cadre d'engrenage fixé sur le bâti de machine. L'élément d'engrenage arrière est non seulement engrené avec la crémaillère droite du cadre d'engrenage mais il est également engrené avec la crémaillère.
