1. A gearbox with gears, comprising:
a driving wheel and a driven wheel, the driving wheel and the driven wheel rotating on a common shaft, and with a cursor arranged transversely to the common shaft of the driving wheel and the driven wheel and sliding with respect to the driving wheel and the driven wheel,
wherein the driving wheel has a surface facing the driven wheel and the driven wheel has a surface facing the driving wheel,
wherein the driving wheel has crown gears arranged on different diameters of the driving wheel, and the crown gears of the driving wheel have teeth protruding from the surface of the driving wheel facing the driven wheel,
wherein the driven wheel has crown gears arranged on different diameters of the driven wheel, and the crown gears of the driven wheel have teeth protruding from the surface of the driven wheel facing the driving wheel,
wherein the cursor has a first end and a second end opposite the first end and further comprises a first gear arranged at the first end of the cursor and a second gear arranged at the second end of the cursor,
wherein the cursor has an axis and the first gear at the first end of the cursor and the second gear at the second end of the cursor rotate around the axis of the cursor and are configured for transmitting motion from the driving wheel to the driven wheel,
wherein the first gear at the first end of the cursor engages in one of the crown gears of the driving wheel arranged on different diameters of the driving wheel and the second gear at the second end of the cursor engages in one of the crown gears of the driven wheel arranged on different diameters of the driven wheel, and
wherein the cursor slides inside a seat formed in the common shaft of the driving wheel and the driven wheel.
