PCT No. PCT/FR87/00516 Sec. 371 Date Oct. 31, 1988 Sec. 102(e) Date Oct. 31, 1988 PCT Filed Dec. 23, 1987 PCT Pub. No. WO88/05009 PCT Pub. Date Jul. 14, 1988.A mechanism based on a reduction gear assembly which produces two torques of equal intensity, both counter-rotational, applied to rotating shafts which may or may not be positioned coaxially. This torque force is achieved without transmitting any torque to the supporting structure. The mechanism comprises two reduction gearboxes with planetary gear trains consisting of internal planet gear wheels linked to the counter-rotating input shafts, satellite gear wheels, freely rotating on their planet pinion cage which is connected to the counter-rotating output shafts, as well as external planet gear wheels interlocked and hence constrained to rotate in the same direction, thereby balancing the torques by reducing speed on one output shaft and accelerating speed on the other shaft.
