Beschreibung
Zusammenfassung:	The utility model discloses a double-rigid-gear harmonic speed reducer with a flexible gear provided with a groove, which comprises a wave generator, a flexible bearing arranged on the wave generator, the flexible gear arranged on the outer ring of the flexible bearing, the flexible gear being in a straight cylinder shape, a first rigid gear and a second rigid gear arranged outside the flexible gear, wherein the tooth number of one rigid gear is the same as that of the flexible gear in the meshing area of the rigid gear, and the tooth number of the other rigid gear is larger than that of the flexible gear in the meshing area of the rigid gear. A groove is formed in the outer wall of the flexible gear and divides flexible gear teeth on the flexible gear into first meshing area flexible gear teeth and second meshing area flexible gear teeth in the axial direction, the first rigid gear is correspondingly meshed with the first meshing area flexible gear teeth, and the second rigid gear is correspondingly meshed w
