<p>Mechanical continuous speed variator defined by at least one multiplier group (50) comprising: a drive shaft (1) and a driven shaft (9) parallel to the drive shaft, a gear (2) keyed on drive shaft (1); at least two pinions (5) meshing with the gear (2) and revolvingly mounted to the driving shaft (1) at a fixed distance from it, a pin (4) of the pinion (5) and a freewheel mechanism (3) interposed between each pinion (5) and its pin (4); at least two thrust elements (20), each mounted at a first end of the relative pinion pin (4), a transfer element (7), rigidly coupled to the driven shaft (9) and comprising a guide (42) for each of the pinion pin (4), with each thrust element (20) slidably inserted in a guide (42) in order to to rotate the transfer element (7) when the relative pin (4) is rigidly coupled to the pinion (5); and translation regulation means (32) on which the driven shaft (9) is rotatably mounted.</p> |
