ABSTRACT:
A gearbox with a driving shaft connected to a cone which is opposed to a second cone and is parallel thereto. An actuating mechanism of both cones includes a rolling axial crown, and a plurality of rollers of a curve-concave generatrix, mounted on a common support. The rollers are mounted with a freedom of rotation on their own axles, which sufficiently facilitates the axial movement of the crown with regard to the couple of contrapositioned cones, while at the same time they are coated with a material having a high coefficient of friction, to ensure the dragging of the crown through a part of the actuating cone and the dragging of the cone driven by a part of the crown.
