Key Features

 
Flat Wire Torsion Spring
  • Torque Generation

    Torsion springs primarily generate torque, or rotational force, when twisted or rotated.

  • Energy Storage

    They store mechanical energy when deflected, which can then be released to perform work or return a mechanism to its original position.

  • Direction of Wind

    Torsion springs can be designed to wind in either a clockwise or counter-clockwise direction, depending on the application.

  • Leg Configurations

    They can have various leg configurations, including straight, hooked, or custom-formed, allowing for different attachment methods.

 

Materials
 

Stainless Steel

Offers good strength, durability, and corrosion resistance.

High-Carbon Steel

Provides high strength and fatigue life.

Specialized Alloys

Such as beryllium copper, for specific properties like electrical conductivity or non-magnetic properties.

Music Wire

A common material for general-purpose torsion springs.

 

Types of Torsion Springs Available

 

 

1
productcate-1-1

Axial Torsion Springs

These springs apply rotational force along the central axis of the coils, ideal for applications needing rotational movement with limited space.

2
productcate-1-1

Double Torsion Springs

Featuring two sets of coils wound in opposite directions, they double the torque capacity for a given size, often used in counterbalancing mechanisms.

3
productcate-1-1

Tangential Torsion Springs

They apply force along the tangent of the coil, providing a direct and smooth force application, suitable for applications where a linear force along a curved path is needed.

4
productcate-1-1

Radial Torsion Springs

These springs exert force outwards from the center, useful for applications requiring expansion or counteracting inward forces.

 

 
 
Applications
01.

Industrial Machinery

Torsion springs are used in clamping devices, counterbalance systems, and automated assemblies.

02.

Aerospace

Essential for flight control mechanisms and landing gear components.

03.

Medical Devices

Used in surgical instruments and diagnostic equipment where precise force control is needed.

04.

Scientific Instruments

Torsion balances, like the one used by Cavendish, utilize torsion springs to measure very weak forces.
