Abstract
A mechanical reducer with high reduction ratio, includes a box-like case (C), an input shaft (I), rotatably supported by the case and adapted to be brought into rotation at an input angular speed (VI), and an output shaft (U), mechanically connected to the input shaft via reduction members (1) and adapted to provide an output angular speed (VU) that is reduced with respect to the input speed. In the reducer device (300), the reduction members include: an input movable drive group (310), conducted in rotation by the input shaft and including one first secondary toothed wheel (Z2) and one second secondary toothed wheel (Z3) integral therewith; a reference fixed drive group (320), including a reference toothed wheel (Z1) which engages the first secondary toothed wheel; an output movable drive group (330), mechanically connected to the output shaft and including an output toothed wheel (Z4) which engages the second secondary wheel.
