IT ENG Torsion springs are either simple or complex in shape. The former are torsion cylindrical helix springs stressed, by means of two terminals integral with the ends of the helix itself, by a torque acting on a plane perpendicular to the axis of the spring body. The couple causes tensions, of which the bending tension is predominant. More complex are the double torsion springs consisting of two cylindrical helical springs obtained from a single suitably folded wire. The terminals are a central one that joins the two windings and the two side ones. Machined wire diameter The dimensional range of the wire used goes from a diameter of 0.30 mm to 3.00 mm.
