Torsion Springs

S R Spring offers a selection of torsion springs with legs of equal length oriented at varying unloaded angles. Torsion springs can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centerline axis. They offer resistance to twist or rotationally applied force. A spring of this type will reduce in body diameter and increase slightly in body length when deflected in the preferred direction of the fabricated 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.

1. Hold the spring in one hand, and the verniercalipers in the other hand.
2. Place thevernier caliper “teeth” on the inside diameter. This is called the Inside Diameter (I.D.).
3. Place thevernier calipers on the “leg” to measure the wire. This is called Material Size (or Wire Diameter).
4. Place thevernier calipers on the working coils of the spring. This is called the Body Length.
5. Count the total coils, beginning at one end, just under where the leg leaves the body. Count to the other end, all full coils, and any fraction thereof. This is called Number of Coils and determines leg position. i.e. 90°, 180°, etc.
