Abstract

L'invention concerne un système de couplage pour des arbres de transmission de couple ayant des éléments de couplage et permettant d'aligner facilement ces éléments de couplage quand les arbres présentant les éléments de couplage sont serrés ou libérés par l'application d'un couple. Le système de couplage pour arbres de transmission de couple comprend des parties saillantes convexes en forme de croix (111) sur l'arbre moteur (101) et des rainures concaves en forme de croix (211) dans un arbre rotatif (201), l'arbre moteur (101) étant pourvu d'une partie saillante convexe, centrale, arrondie (120) et l'arbre rotatif (201) étant pourvu d'un trou central concave (130). Dans ces conditions, quand les arbres présentant les éléments de couplage sont serrés ou libérés par le couple, la partie saillante convexe centrale arrondie (120) sur l'arbre moteur (101) est d'abord insérée dans le trou central concave (130) avec les axes des arbres alignés, et ensuite l'arbre moteur (101) est tourné pour que les parties saillantes convexes en forme de croix (111) entrent facilement dans les rainures concaves en forme de croix (211) dans l'arbre tournant (201).
