Abstract (en)

[origin: FR2777216A1] The invention concerns a system for eliminating reactions caused by torque in a tool-carrying machine, which consists in incorporating in the machine an inertia element. The invention is characterised in that the rotary drive tool-carrying machine further comprises a rotating energy source (8) for a rotating shaft (2a) bearing tool equipment about an axis (X'X), a flywheel (6) which is temporarily driven in rotation by the rotating energy source (8) and restores stored kinetic energy for driving in rotation the tool equipment bearing shaft (2a) via a speed reduction unit (5) and a torque limiter (4).
