Torsion springs can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the axis of the body’s centerline. They offer resistance to torsion or rotationally applied force. Such a spring will reduce the diameter of the body and slightly increase the length of the body when deflected in the preferred direction of the manufactured wind.

Torsion springs are helical springs that exert a torque or rotary force. The ends of a torsion spring are attached to other components, and when those components rotate around the center of the spring, the spring tries to push them back to their original position. Although the name implies otherwise, torsion springs are subject to bending stresses rather than torsional stresses.

This type of spring normally has a closed wound, but may have a pitch to reduce friction between the coils. They offer resistance to torsion or rotationally applied force. Depending on the application, torsion springs can be designed to run either clockwise or counterclockwise, thus determining the direction of the wind.



Torsion springs are designed to store and release rotational energy. Tension springs and compression springs work with push-pull force, while torsion springs work with torsion force.
