Torsion springs are mechanical components that store and release energy by twisting. They are commonly used in various applications, such as door hinges, clothespins, and toys, to provide a force that opposes the applied torque.
This article explores how torsion springs work, their benefits, and their applications in different industries.

A torsion spring is a type of spring that exerts a torque or rotational force when twisted. It is typically made of metal, such as steel or music wire, and is designed to store energy when twisted and release it when untwisted.
Torsion springs are used in various applications, including mechanical devices, toys, and tools. They come in different shapes and sizes, depending on the specific application requirements.
There are two main types of torsion springs: double torsion springs and single torsion springs.
Double torsion springs
Double torsion springs have two coils that twist in opposite directions. They are commonly used in applications that require a constant torque, such as in clock mechanisms.
Single torsion springs
Single torsion springs have one coil that twists in one direction. They are used in applications that require a variable torque, such as in clothespins and door hinges.
Torsion springs are designed to withstand repeated twisting and untwisting without losing their shape or strength. The design and construction of torsion springs depend on the specific application requirements, such as the amount of torque needed, the space available, and the material used.
The wire diameter, coil diameter, and number of coils are critical factors in determining the spring’s torque capacity. The spring’s material also plays a significant role in its performance, with high-carbon steel and stainless steel being the most common materials used.
A torsion spring works by storing energy when twisted and releasing it when untwisted. The amount of energy stored in the spring depends on the amount of twist and the spring’s stiffness.
The torque exerted by the spring is proportional to the amount of twist and the spring’s stiffness. The torque can be calculated using the following formula:
Where:
– Torque (T) is the force exerted by the spring in Newton-meters (Nm)
– Spring constant (k) is a measure of the spring’s stiffness in Newton-meters per radian (Nm/rad)
– Twist (θ) is the angle of twist in radians
The spring constant depends on the spring’s design and construction. It can be calculated using the following formula for a cylindrical torsion spring:
Where:
– k is the spring constant in Nm/rad
– G is the modulus of rigidity of the spring material in Pascals (Pa)
– r is the coil radius in meters (m)
– L is the length of the spring in meters (m)
– n is the number of active coils
The modulus of rigidity is a material property that measures the material’s resistance to deformation under shear stress. It can be found in material property tables for the specific material used.
The performance of a torsion spring is affected by several factors, including the material used, the spring’s design, and the operating conditions.
The material used in the spring affects its stiffness, strength, and fatigue resistance. High-carbon steel and stainless steel are the most common materials used for torsion springs due to their high strength and fatigue resistance.
The spring’s design, including the wire diameter, coil diameter, and number of coils, also affects its performance. A larger coil diameter and more active coils result in a lower spring constant and a higher torque capacity.
The operating conditions, such as temperature and humidity, can also affect the spring’s performance. High temperatures can cause the spring to lose its stiffness, while high humidity can cause corrosion and reduce the spring’s lifespan.
Torsion springs are widely used in various applications due to their numerous benefits. Some of the key benefits of using torsion springs include:
Torsion springs are designed to store and release energy efficiently. When twisted, the spring stores potential energy, which is released when the spring untwists. This property makes torsion springs ideal for applications requiring a consistent force or torque, such as in toys, door hinges, and mechanical devices.
Torsion springs provide precise control over the force or torque applied. The amount of torque exerted by the spring can be easily adjusted by changing the twist angle. This feature is particularly useful in applications where accurate positioning or control is required, such as in clock mechanisms and measuring instruments.
Torsion springs are made from high-quality materials, such as high-carbon steel and stainless steel, which provide excellent strength and fatigue resistance. When properly designed and manufactured, torsion springs can withstand repeated twisting and untwisting without losing their shape or strength. This durability ensures a long lifespan, reducing the need for frequent replacements and maintenance.
Torsion springs are versatile components that can be used in various applications. They come in different shapes and sizes, allowing them to be easily integrated into different mechanical systems. Whether it’s a small toy or a large industrial machine, there is a torsion spring suitable for the application.
Torsion springs are used in various industries for different applications. Some of the key applications of torsion springs include:
