What is a Torque Spring?

Torque springs are mechanical parts used to store and release rotational energy. Their operation involves a twisting action. When a torque spring is twisted, it creates torque, or twisting force, in a counter direction of the applied force. This unique feature, torque springs are utilized in a wide range of applications, ranging from simple household items to complex machinery.

Varieties of Torque Springs

Torque springs are available in different types, each intended for a particular use:

Helical Torque Springs: These are the most common type of torque springs. Usually, they are crafted from a wire that has been coiled and twisted into a helical shape. Helical torque springs can be designed with an open or closed wound configuration, depending on specific needs.
Spiral Torsion Springs: These springs are made from a strip of flat material wound into a spiral. Commonly used in devices like measuring tapes and clocks, where small form factor is needed.
Solid Bar Springs: Made from solid bars, these springs are twisted lengthwise. Bar torque springs are usually employed in industrial applications, requiring high torque is needed.
Double Torque Springs: These springs comprises two torsion springs coiled together, often used to provide a balanced force.

Building and Materials
Torque springs are usually crafted from high-carbon steels, stainless steels, or various alloys preferred for their strength and resistance to fatigue. The wire diameter, coil thickness, number of coils, and overall length influence the strength and characteristics of the spring.

In the creation of a torque spring, the material is wound around a central rod to create coils that can resist torsional forces. The ends of the spring are commonly made into loops or hooks to facilitate attachment to other systems. The precision of the winding and material choice are critical in guaranteeing performance and durability of the spring.

Applications of Torque Springs
Torque springs are utilized in many industries, due to their capability to provide consistent rotational force. Frequent uses include:

Timepieces: Torque springs play a vital role in keeping accurate time. They provide the torque needed to turn the cogs and ensure accurate time.
In the automotive sector: Torsion springs are found in various automotive components, such as trunk lids, throttle return mechanisms, and reclining seats. They provide the reliable performance of these mechanisms.
Aerospace: Torque springs play a key role in aeronautical control systems, because precise and reliable torque is essential for safe flight.
Industrial Machinery: Machines rely on torque springs in functional systems such as clutches, brakes, and valves. These springs provide the force needed to activate or deactivate components.
In electronic devices: Torque springs are commonly used in electronics including computers, printers, and cameras to ensure reliable functioning.
In doors: Torque springs are integral in door hinge systems, generating the force to keep doors closed.
Workout gear: Torsion springs are incorporated into fitness devices to generate resistance and enable effective workouts.
