Double Torsion Springs

Double Torsion
A double torsion spring is just as the name suggests. It is simply a spring that is designed to incorporate two torsion springs within one unit. It consists of one set of coils, wound in a right hand fashion and another set of coils, wound in a left hand fashion and are bridged through the center. The total force of a double torsion spring is the sum of the two springs added together.

Torsion springs or torsional springs and double torsion springs are used in many different applications and you can typically find them in all major household appliances, medical devices, military/aerospace applications plus many more.

Tips for Designing a Torsion Spring:

Some of the key considerations in the design phase are the effects of friction and the arm deflection on the torque. To reduce the effects of friction, the design may include a pitch (the amount of space between each coil), and the inside diameter should be sufficient to provide clearance when maximum deflection is applied. The leg end configurations are limitless here, but careful consideration should be used if cost is a factor. The design ends can be as simple straight legs, hooks, or angular bends and may assist or aid with part retention. More complex geometries are possible such as full or multiple loops or a number of offsets in order to fit the assembly designs. Any design considerations can be discussed with one of our design consultants.
