Torsion Springs – Function, Structure & Design Considerations

  A torsion spring is a mechanical spring that stores energy through twisting deformation when subjected to rotational torque. It is commonly used in mechanisms requiring rotational force return, such as door hinges, clamps, switches, and automotive components.

Function & Structure:

A torsion spring consists of helical coils and two legs (spring arms). When the legs are rotated inward or outward, the spring generates torque and a restoring force. Although capable of bi-directional rotation, torsion springs are typically designed to operate in one direction for optimal performance.

Design Considerations:

  1. Wire Diameter: Affects the spring’s stiffness and torque capacity.

  2. Number of Coils: More coils allow greater angular deflection and flexibility.

  3. Leg Length and Angle: Customizable into L-shape, U-shape, Z-shape, or hook form to suit installation space and force direction.

  4. Winding Direction: Left-hand or right-hand winding is determined based on the application’s rotational requirements.

  5. Material Selection: Choose materials such as SUS304, carbon steel, phosphor bronze, or Inconel based on operating environment (e.g., corrosion, temperature, fatigue).

Types of Torsion Springs:

1.Single Torsion Spring: Designed for applications requiring torque in a single direction.

       2.Double Torsion Spring: Two springs wound in opposite directions and connected by a central straight section, offering greater

         or balanced torque output for symmetrical force distribution.
