What Are Torsion Springs?
Torsion springs are helical springs that work by twisting their ends along their axis to exert a rotational force, or torque. Unlike extension springs that stretch or compress, torsion springs operate through angular deflection. This unique property allows them to store and release energy efficiently, making them ideal for applications that require precise control of movement.
The design of a torsion spring involves coiling a piece of wire into a helical shape. The number of coils and the wire diameter significantly impact the spring’s performance. The ends of the torsion spring can be configured in various ways to attach to other components, providing flexibility in their application.
How Do Torsion Springs Work?
The working principle of torsion springs is based on the application of torque or rotational force. When one end of the spring is twisted, it exerts an equal and opposite force to return to its original position.
This stored energy is what makes torsion springs so effective in applications where controlled, reversible motion is required. For example, in a garage door mechanism, torsion springs provide the necessary torque to counterbalance the weight of the door, allowing it to be lifted easily. The amount of torque produced by a torsion spring depends on several factors, including the number of coils, the wire diameter, and the material used in manufacturing.
Torsion Spring Design Applications
Torsion springs are highly versatile and used in numerous applications due to their ability to store and release angular energy. Here are 10 examples of where and how torsion springs are used:
- Clothespins & Mousetraps:
Maybe the most recognized example of a torsion spring. These springs store energy and release it to hold clothing or close a trap mechanism. - Garage Doors:
Torsion springs provide the necessary counterbalance to lift and lower heavy garage doors smoothly and safely. - Clocks and Watches:
Used in the mechanisms to control the movement of the hands and maintain accurate timekeeping. - Automotive Industry:
Found in vehicle suspension systems, door hinges, and throttle return mechanisms for smooth operation and control. - Industrial Machinery:
Used in various machinery components to maintain tension and return parts to their original position after movement. - Toy Industry:
Incorporated into mechanisms of wind-up toys to store and release energy, enabling movement and functionality. - Aerospace Industry:
Utilized in aircraft control surfaces and landing gear systems to provide precise control and reliable operation. - Medical Devices:
Found in surgical instruments, inhalers, and other medical tools where controlled movement and return to position are essential. - Electronic Devices:
Used in switches, relays, and connectors to maintain contact and ensure reliable electrical connections.
These examples illustrate the wide-ranging applications of torsion springs, highlighting their importance in both everyday items and specialized industrial equipment.
The Importance of Custom Torsion Springs
Custom torsion springs are essential for applications that require specific torque characteristics, dimensions, or configurations. Torsion springs can be designed to accommodate unique load requirements, environmental conditions, and mechanical constraints.
This level of customization ensures that the springs provide the necessary performance and durability for demanding applications.
Understanding Torsion Spring Materials and Design
Designing a custom torsion spring involves several critical considerations, including:
- Material Selection:
The choice of material affects the spring’s strength, durability, and resistance to environmental factors. Common materials include steel, stainless steel, and high-carbon steel. - Wire Diameter:
The diameter of the wire used in the spring affects its torque capacity and overall strength. - Number of Coils:
The number of coils determines the spring’s ability to store energy and its overall torque output. - Leg Configuration:
The ends of the spring, or legs, can be bent into various shapes to fit the specific mounting requirements of the application.
Precision in torsion spring design is crucial to ensure that the spring performs as expected and has a long service life.
The Wide Range of Torsion Spring Configurations
Torsion springs come in various types, each suited to different applications:
- Single Torsion Springs: These springs consist of a single coil and are used in applications requiring moderate torque.
- Double Torsion Springs: Double torsion springs consist of two coils wound in opposite directions and connected in parallel. This configuration provides greater torque and stability.
- Spiral Torsion Springs: These springs are used in precision instruments like clocks and watches, where compact size and high torque are essential.
Each type of torsion spring offers unique advantages and is chosen based on the specific requirements of the application.
Torsion Spring Coil Configurations: Single vs. Double
Choosing between single and double torsion springs depends on the application’s torque and stability requirements. Single torsion springs are simpler and suitable for applications with moderate torque needs.
In contrast, double torsion springs provide higher torque and better stability due to their dual-coil configuration.
Double torsion springs consist of two springs wound in opposite directions. This configuration allows them to work in parallel, providing greater torque and reducing the risk of buckling under load.
Double torsion springs are ideal for heavy-duty applications where reliability and performance are critical.

Spiral Torsion Springs (Clock Springs):
Spiral torsion springs, also known as clock springs, are a unique type of torsion spring used in applications requiring compact size and precise torque control.
These springs are commonly used in timekeeping devices, such as clocks and watches, where they store and release energy to drive the movement of the hands.
Spiral torsion springs are made by winding a flat strip of metal into a spiral shape. This design allows them to provide a constant torque over a wide range of motion, making them ideal for applications requiring precise and consistent performance.
