<p>A mechanical reducer comprises a body (2) supported in rotation with respect to which are an input shaft (3) and an output shaft (4) kinematically coupled to each other through mechanical transmission means. The mechanical transmission means have a first inner gear comprising a first gearwheel (5) with outer toothing coupled so as to be intermeshed with a second gearwheel (6) with inner toothing. Advantageously, the first gearwheel (5) is supported by an eccentric portion (3a) having preset eccentricity (E 1 ) of the input shaft (3) so as to rotate idly. The pitch line diameter (Dp 2 ) of the second gearwheel (6) being equal to the pitch line diameter (Dp 1 ) of the first gearwheel (5) increased by twice the value of the abovementioned eccentricity (E 1 ).</p> |
