The gearbox (29) comprises an annular support (31), on which pairs of gears (33A-33J) for the input of motion to the gearbox are rotatably supported. Each pair of gears comprises a first gear (35) adapted to receive an input motion, and a second gear (37); the first gear and the second gear being coaxial and angularly coupled to each other to rotate integrally. Each pair of gears defines a transmission ratio different from the transmission ratios defined by the other pairs of gears. The annular support is angularly movable around a selection axis to selectively bring one of said pairs of gears into an angular take-off position of the motion in input to the transmission ratio gearbox. The gearbox further comprises a mechanical connection between the second gear of the pair of gears which is in the angular take-off position of the motion in input to the transmission ratio gearbox, and an output shaft (45) having an axis of rotation (A-A) parallel to the selection axis or coincident therewith, wherein the output shaft passes inside the annular support.
