Les engrenages externes (16a, 16b) sont engrenés un par un avec les dents internes (18) et tournés en faisant tourner l’arbre rotatif (11) pour faire tourner les engrenages externes (16a, 16b) selon une quantité équivalente à une différence du nombre de dents entre les dents externes (17) et les dents internes (18) pour chaque rotation de l’arbre rotatif (11), et le mouvement rotatif des engrenages externes est transmis à un élément intérieur (21) par l’intermédiaire d’un moyen de transmission de couple (30) pour faire tourner l’élément intérieur (21) à une vitesse réduite. L’élément intérieur (21) est supporté de façon rotative par des rangées doubles d’éléments roulants (26a, 26b) assemblés entre l’élément intérieur et un élément extérieur (19) installé sur l’extérieur de l’élément intérieur et relié au carter (1). Les diamètres de cercle primitif des doubles rangées d’éléments roulants (26a, 26b) sont différents les uns des autres, et les éléments roulants (26a) avec le plus grand diamètre de cercle primitif sont disposés sur le côté des engrenages externes (16a, 16b) pour augmenter la rigidité de support de l’élément intérieur (21). L’autre extrémité de l’arbre rotatif (11) est supportée de façon rotative par l’élément intérieur (21) pour empêcher l’autre extrémité de l’arbre rotatif (11) de pivoter.
