Torsion
General Information Required
When ordering Torsion springs it’s always best to provide a sample or a drawing.
The minimum information needed to quote is listed below:
- Type of material (can be discussed or described)
- Wire diameter
- Outer diameter
- Total coils (TC)
- Direction of wind
- Type of ends (a drawing or sample is most beneficial if your spring has bends in the tails/legs)
- Body length (important if there is spacing between the coils)
- Quantity needed
Definition
Torsion springs are helical coil springs that exert a torque or rotary force. They can be coiled either left hand wind, right hand wind or in the case of double torsions, both hand winds.
Spring Action
The deflection/travel of torsion springs are determined by the diameter of the body, size of the wire and the number of coils. When torque is applied to a torsion spring, the body length grows (because the spring is winding up and increasing body coil count) and the body diameter decreases. Torsion springs should always wind up during operation and never unwind from the free/relaxed position and should be supported over a rod/mandrel whenever possible.
Direction of Wind
Left Hand Wind
Right Hand Wind
Double Torsion
(Left & Right Hand Wind)
Counting Coils (total coils)
End Styles
The most common and economic type of end is tangential legs, picture “b” (straight off the body of the spring) which require less set up. They can also be radial external, picture “c” (hooked), radial over-center, picture “d” (hinged) and axial, picture “a” (offset or lateralized).
These ends can be used in any combination along with different lengths, with bends and positioning.
