Rotational speed and torque mechanical transducer

A rotational speed and torque mechanical transducer, comprising:

• (a) a epicyclic gearing presenting a sun gear (6) secured on a main shaft (5), at least one planet gear (40, 46) and a planet carrier (T) for carrying the said planet gears, rotatably mounted around the axis of the said main shaft (5);
• (b) an active mass (42, 48) connected with each planet gear (40, 46), whose alternating torques produced by the inertia forces are transmitted to the main shaft (5), and whose barycenter lies on the axis of rotation of the respective planet gear;
• (c) coupling means to couple the driving shaft (60, 460, 600) to the said planet carrier (T) for driving the said carrier (T) into swinging rotational movement around its rotational axis (5);
• (d) at least a pair of freewheel couplings (RL1,RL2, RL3,1RL1,1RL2,1RL3) which provide their locking action in opposite rotational directions, limiting the angular speed of the main shaft (5), and at least one output shaft (77,177,277,377,477,577) coupled, through at least one freewheel coupling, with the main shaft (5).
