Disclosed is a low reaction oscillating mass-based torquing tool (1) wherein an oscillating mass (4) is excited into near resonant oscillation by reversing pulses resulting increased oscillation about a torsion spring (3) to the point where the torque associated with the energy stored in the torsion spring exceeds the torque required to further tighten a fastener and the torque released from the torsion spring tightens the fastener while a biasing torque assures application of the released torque in the tightening direction only.
Outil de serrage (1) basé sur une masse oscillante (4) à réaction basse qu'on excite afin de lui imprimer une oscillation pratiquement résonante, par des impulsions inversées, ce qui permet d'obtenir une augmentation de l'oscillation autour d'un ressort de torsion (3) jusqu'à un point auquel le couple associé à l'énergie accumulée dans le ressort de torsion dépasse le couple nécessaire pour continuer à serrer un élément de fixation et auquel le couple libéré du ressort de torsion serre l'élément de fixation, tandis qu'un couple de sollicitation permet d'appliquer le couple libéré uniquement dans le sens de serrage.
