<p>The invention relates to a system which transmits the rotation motion from one shaft to another one by increasing or decreasing the transmission ratio, while maintaining the same sense of rotation or changing the sense of rotation of the driven shaft as compared with the driving shaft without using the classic gear wheel systems, intended for any mechanism requiring the transmission of a rotation motion. According to the invention, the transmission system comprises a driving shaft () on which a circular eccentric () is rigidly fixed to engage and keep in motion a circular plate () mounted on a bearing () by means of some guiding rollers (), moving along the outline of some circular recesses () within a chassis (), the plate () transmitting the motion forward, by some driving rollers () to a wheel () which exhibits some curves () in the shape of internal or external evolvent alternating with some nests (), the wheel () being integral with a disc () by means of some screws () and the disc () being wedged on a driven shaft () located inside the driving shaft ().</p> |
