Torsion Springs

Torsion Springs

Torsion springs used to transmit torque or to store torsional energy are referred to as torsion springs. Since the load is by and large always transmitted via the long legs at the end of the springs, they are also referred to as leg springs.

Torsion/leg springs are only cold-formed. Depending on the application, different materials (spring steel wire and spring wire made of non-rusting wires) are used.

Key Features of Torsion Springs:

• Functionality: They work by twisting along their axis to store energy, rather than extending or compressing.
• Load Application: The load is generally applied sideways to the long legs, causing the coil diameter to decrease as it tightens.
• Leg Styles: Legs can be configured with various bends, hooks, or loops to attach to components like hinges, levers, or shafts.
• Stress Type: Although called torsion springs, they are actually subjected to bending stress rather than torsional stress during operation.
• Design Considerations: They must be loaded in a direction that decreases their coil diameter to avoid excessive stress, and a mandrel is often used to support
