Abstract
A reduction gear with two reduction stages including a first reduction stage consisting of a wheel and worm screw system. The system has a screw and a first wheel. A second stage includes a pinion meshing with a second toothed wheel. The wheel of the wheel and worm screw system includes two lateral parts spaced axially and equipped with teeth adapted to mate with the thread of the screw. A center part is located between the lateral parts, and includes teeth with an outside diameter less than the diameter of the teeth of the first wheel, this center part forming the pinion of the second reduction stage.
