Abstract
The reduction unit comprises an input stage S or S' having the function of converting the angular velocity ω1 of the input member into two rotary movements in opposite directions and with suitable slip of the angular velocities, namely with angular velocities +ω', -ω'' which are slightly different from each other in terms of absolute value. The reduction unit also comprises an output stage D or D' consisting of a speed differential, to the planetary gears 4, 4' of which the rotary movements in opposite directions and at the said angular velocities +ω',-ω'' are sent by means of the gearings of the input stage. According to a constructional variant, the slip in the angular velocities may be performed inside the output stage D'. The output member of the reduction unit 206, which is the output shaft of the differential, rotates at an angular velocity ω2 in accordance with the equation: <IMAGE> <IMAGE>
