REDUCTEUR MECANIQUE A VIS SANS FIN
The invention concerns a mechanical reduction gear (156) comprising: - an input shaft (158) rotated by a motor, - an output shaft (160) coaxial with the input shaft (158), - an endless screw (250) mounted coaxially on the input shaft (158), and - a gear train (200) comprising: - three first gears (252) uniformly distributed around the endless screw (250), each meshing with the endless screw (250) and moveably mounted to rotate about a first axis perpendicular to the axis of the endless screw (250), - for each first gear (252), a second conical gear (254) coaxially attached to the first gear (252), - for each second gear (254), a conical third gear (256), meshing with the second gear (254) and rotatable about a second axis of rotation parallel to the axis of rotation of the endless screw (250), - for each third gear (256), a fourth gear (258) coaxially attached to the third gear (256), and - a fifth gear (260) coaxially mounted on the output shaft (160) and which meshes with the or each fourth gear (258).
