Background

The torsion spring belongs to a spiral spring. The ends of the torsion spring are fixed to the other components, and as the other components rotate about the spring center, the spring pulls them back to the original position, creating a torque or rotational force. The torsion spring can store and release angular energy or statically hold a device by rotating a moment arm about the central axis of the spring body. Such springs are typically solid, however, the coils are spaced to reduce friction. They produce resistance to rotational or rotational external forces. The handedness (clockwise or counterclockwise) of the torsion spring is designed to determine the handedness of the spring, depending on the application requirements. The turns are either tightly wound or wound separately, and are able to accommodate torsional loads (at right angles to the spring axis). The end of the spring may be wound as a hook or straight torsion arm.
