Torsion Spring Dimensions
Correct dimensions are crucial in identifying the right spring for your application. Use the steps and diagram below to measure accurately measure your torsion springs.
- Hold the spring in one hand, and the calipers in the other hand.
- Place the caliper “teeth” on the inside diameter. This is called the Inside Diameter (I.D.).
- Place the calipers on the “leg” to measure the wire. This is called Material Size (or Wire Diameter).
- Place the calipers on the working coils of the spring. This is called the Body Length. Place the calipers on the working coils of the spring. This is called the Body Length.
- 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 the Number of Coils and determines leg position. i.e. 90°, 180°, etc.
- Determine the direction of the coil (Wind Direction). See diagram for hand/finger illustration. Right Hand Wind or Left Hand Wind.
About Torsion Springs
Overview
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.
MW offers a selection of stock and standard torsion springs with legs of equal length oriented at varying unloaded angles, as well as custom torsion spring manufacturing.
Torsion Springs Characteristics
The torsion spring configuration is created for the purpose of storing and releasing angular energy or for the purpose of statically holding a mechanism in place by deflecting the legs about the body centerline axis. 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.
The direction of the fabricated wind can also be important for torsion spring applications due to the leg bearing/attachment location having to be on the left or right side upon assembly.
A torsion spring is normally supported by a rod (mandrel) that is coincident with the theoretical hingeline of the final product.
Typical Tolerances
Tolerance values for torsion springs depend on the body-diameter to wire-diameter ratio and are about +/- 10% in torque and +/- 5% in diameter.
