Abstract

Ressort de torsion (2) haute densité de couple à faible raideur, pour réducteur à engrenages à axes concourants, comportant;une pluralité de lame (5) équireparties autour d'un axe Y et s'étendant radialement; chacune desdites lames (5), comportant un bord intérieur (5a) et un bord extérieur (5b), parallèle à l'axe Y; le bord extérieur (5b) coopérant avec un pignon denté (3) d'axe de rotation Y; le bord intérieur (5a) coopérant avec un arbre (4) d'axe de rotation Y;chacune desdites lames (5) comportant en outre, de part et d'autre du bord intérieur (5a), une face biaisée (5a1;5a2) s'étendant parallèlement à Y, caractérisé en ce que chacune desdites face biaisée (5a1;5a2), de ladite lame (5), de ladite pluralité de lame (5), est en contact coplanaire et alignée, avec la face biaisée (5a1;5a2) jouxtante de la lame (5) adjacente, de manière que ladite pluralité de lame (5), forme une forme annulaire d'axe de révolution Y. La pluralité desdites face biaisée (5a1;5a2) étant rattachées entre elles. « Figure pour l’abrégé : Figure 1 »Torsion spring (2) high torque density with low stiffness, for gear reducer with concurrent axes, comprising;a plurality of blades (5) evenly distributed around a Y axis and extending radially; each of said blades (5), having an inner edge (5a) and an outer edge (5b), parallel to the Y axis; the outer edge (5b) cooperating with a toothed pinion (3) of axis of rotation Y; the inner edge (5a) cooperating with a shaft (4) of axis of rotation Y; each of the said blades (5) further comprising, on either side of the inner edge (5a), an angled face (5a1; 5a2 ) extending parallel to Y, characterized in that each of said biased face (5a1; 5a2), of said blade (5), of said plurality of blades (5), is in coplanar and aligned contact with the biased face ( 5a1; 5a2) adjoining the blade (5) adjacent, so that said plurality of blade (5) forms an annular shape of axis of revolution Y. The plurality of said biased face (5a1; 5a2) being attached to each other. "Figure for abstract: Figure 1"
