A spiral spring delivers torque as it unwinds — ideal for drives, returns and toy or instrument mechanisms. Stiffness depends on the strip thickness, width and total length.
Set the strip thickness and width, outer diameter, arbor and number of turns; the tool computes the angular rate and max safe torque.
