Torsion Spring Design
Torsion spring can store and release angular energy or statistically hold a mechanism in place by deflecting the legs about the body center line axis. They offer resistance when twisting or rotation ally applying force. A spring of this type will reduce in body diameter and increase slightly in body length when deflected in the prefabricated wind. Depending on the application, torsion springs can be designed to work in a clockwise or counter clockwise rotation, thus determining the direction of the wind. Common torsion springs are those used in a clothes pin or a garage door.
Data Required for Torsion Springs
It is important to note that while every spring manufacture will have a variety of torsion spring testing equipment and procedures, there is no “standardized method” to test loads for torsion springs (see “Encyclopedia of Spring Design Manufacturers Institute”).
