Abstract
Disclosed is a low reaction oscillating mass-based torquing tool wherein an oscillating mass is excited into near resonant oscillation by reversing pulses resulting in increased oscillation about a torsion spring 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.
