VARIABLE MECHANICAL TRANSMISSION OF A MOVEMENT OF VA AND COMES IN ROTATION MOTION

摘要

The transmission transforms the back and forth of a rack in rotation of an output wheel, by two mechanical links with freewheels which are each assigned to the transfer of movement during one of the two phases of the comings and goings . Each of the back and forth movements of the rack is transmitted to a rotation of the same direction at the output wheel. A rack can pivot about the axis of rotation of said output wheel, while remaining connected to the element that causes its movement back and forth, regardless of this movement. This transmission makes it possible to vary the evolution of the transmission ratio between the movement of the rack and the rotation of the output wheel, both during a cycle of back and forth of the rack and for a set of successive cycles.
