Torsion Springs
Torsion springs are often suited to situations where torque is applied from two directions, as they are designed to offer resistance to externally applied pressures. Torsion refers to the twisting action of the coils. Although the wire itself is subjected to bending stresses rather than torsionally applied stresses. These springs perform at a maximum when supported over a tube or rod.
Description
A torsion spring can be closed or open wound and are usually designed to wind up. As a torsion spring winds up, the coil diameter will decrease and the body length will increase. Though this type of spring is most often made of round wire, we are capable of producing parts out of:
- Round wire
- Square wire
- Rectangular wire
- Special section wire
Direction of Helix
Good design dictates that torsion springs should be used in the direction that winds the coil. When enquiring and ordering torsion springs, be sure to specify either a left or right hand wind.
Mandrel size
Torsion springs are normally used over a supporting mandrel (shaft or arbor). Suggested mandrel sizes allow approximately 10% clearance at the deflections listed. If greater deflection is required, the mandrel size should be reduced.
Specifications
We require the following information for manufacturing purposes.
- Size of material
- Mean diameter
- Body length
- Outside diameter
- Inside diameter
