Abstract

L'invention concerne un coupleur de transmission à vis sans fin. Le coupleur comprend un manchon extérieur tubulaire à rainure intérieure et un élément allongé intérieur à rainure extérieure qui sont couplés de façon à définir plusieurs conduits sans fin permettant la circulation de billes, chaque conduit étant formé par deux spires adjacentes d'un conduit hélicoïdal défini par le manchon extérieur et l'élément intérieur allongé et un conduit de retour s'étendant à partir d'un trou respectif ménagé au travers du manchon et chevauchant lesdites deux spires adjacentes, ledit conduit de retour étant défini par une cavité ménagée dans une plaque fixée sur la surface extérieure du manchon et obturant ledit trou.
