Spiral Spring

Uses of Spiral Springs

Spiral Springs, also known as spiral wound springs or clock springs, are a type of torsion spring that is formed by winding a flat strip of material in a spiral shape. They are characterized by their ability to store and release rotational energy when twisted or wound. Here's some information about spiral springs and their uses:

1. Power Springs: Spiral springs are commonly used as power springs in applications where rotational or torsional energy needs to be stored and released. Power springs are found in devices such as retractable cords, spring-driven motors, and rewind mechanisms. When the spiral spring is wound, it stores energy, and when released, it provides rotational force or torque.

2. Clocks and Watches: Spiral springs have a long history of use in clockwork mechanisms and watches. They serve as the power source for the timekeeping mechanism, providing the necessary rotational energy to drive the hands or other components. The spring is typically wound using a key or crown, and it gradually unwinds to regulate the movement of the clock or watch.

3. Automotive Applications: Spiral springs find applications in the automotive industry, particularly in steering systems. They are used in mechanisms like clock springs or spiral cable assemblies to provide continuous electrical connectivity while allowing rotational movement. These spiral springs are used in steering wheel-mounted controls, such as airbag systems, horn contacts, and audio control switches.

4. Seat Belt Retractors: Spiral springs are employed in seat belt retractors to provide the necessary force for the automatic retraction of seat belts. The spring is wound when the seat belt is extended and then unwinds to retract the belt when released. The spiral spring ensures that the seat belt is properly retracted and stored when not in use.

5. Industrial Applications: Spiral springs find use in various industrial applications. They can be used as counterbalance springs in weighing scales or industrial machinery to provide a balanced and controlled rotational force. Spiral springs are also used in cable reels, which allow cables or wires to be wound and unwound smoothly while maintaining tension.

6. Exercise Equipment: Spiral springs are utilized in exercise equipment to provide resistance and assist with muscle strengthening and conditioning. They can be found in equipment such as exercise bikes, rowing machines, and resistance trainers. Spiral springs offer adjustable resistance levels and smooth, controlled movement.

7. Electrical Applications: Spiral springs are utilized in certain electrical devices and equipment. They can be found in retractable cords, such as those used in vacuum cleaners or power tools. The spiral spring provides the necessary torque to retract and extend the cord, ensuring convenience and proper cable management.

8. Mechanical and Industrial Applications: Spiral springs find use in a variety of mechanical and industrial applications. They can be used in torque limiters, counterbalances, and other mechanisms where controlled rotational force or energy storage is required. Spiral springs can be custom-designed to meet specific torque or load requirements.

9. Custom Applications: Spiral springs can be designed and customized to suit specific requirements in different industries and applications. The dimensions, materials, and characteristics of the spring can be tailored to meet the specific needs of the application, including the desired torque, angular deflection, and load capacity.

These are some of the common uses of spiral springs. Their ability to store and release rotational energy makes them valuable in various applications where controlled rotation or torque is required.
