Abstract

L'invention concerne une roue dentée, une machine pour fabriquer une roue dentée et un procédé pour fabriquer la denture d'une roue dentée. La roue dentée présente une denture plane qui recouvre une première zone de distance radiale, en particulier par rapport à l'axe médian et/ou à l'axe de rotation de la roue dentée. La roue dentée est réalisée sous la forme d'un moyeu et/ou présente un évidement ménagé de manière centrale, est donc en particulier creuse, de telle sorte que la roue dentée peut être emboîtée sur un arbre. La roue dentée, dans la première zone de distance radiale, recouvre une première zone axiale. La roue dentée, dans une deuxième zone de distance radiale, recouvre une deuxième zone axiale. La deuxième zone de distance radiale est espacée radialement de la première zone de distance radiale. La deuxième zone de distance radiale est agencée radialement à l'intérieur de la première zone de distance radiale, la deuxième zone axiale comportant la première zone axiale ou chevauchant au moins la première zone axiale. La roue dentée présente dans la deuxième zone de distance radiale, en particulier sur un col de moyeu de la roue dentée, une épaisseur de paroi et/ou une épaisseur radiale diminuant dans la direction axiale, en particulier à mesure que croît la distance avec la denture plane, diminuant en particulier en douceur et/ou constamment de manière différenciable en fonction de la position axiale.
