Abstract

On produit un rotor (19) cyclique épitrochoïdal intégral à deux étages selon un procédé d'usinage produisant les tolérances désirées dans les deux étages du rotor, sans retirer cette pièce de l'élément (22) la supportant tout au long du procédé de fabrication. Au cours du procédé de fabrication, la pièce (9a) d'ébauche de départ, qui est de préférence un disque circulaire, est fixée sur un élément de support (22), par exemple par mandrin magnétique (22). La surface extérieure d'ensemble (32) de la pièce à usiner (9a) est ensuite mise en rotation selon une trajectoire orbitale, afin de produire le contour épitrochoïdal du premier étage du rotor (9). Ensuite, sans libérer la pièce (9) de la surface de support (22), on procède à une seconde opération d'usinage de précision, à nouveau avec rotation sur une trajectoire orbitale sur la moitié supérieure de la pièce (9a) pour réaliser le contour épitrochoïdal du second étage du rotor (9). Cet agencement offre un procédé peu coûteux permettant de réaliser un rotor (9) cyclique épitrochoïdal intégral à deux étages, dans lequel on obtient la précision requise de chaque contour tout en parvenant à réaliser, et à maintenir les tolérances entre les surfaces épitrochoïdales des deux étages. Un système d'entraînement épicyclique utilisant le rotor cyclique épitrochoïdal intégral à deux étages est également décrit.
