What is a Spiral Spring?
A Spiral Spring (sometimes known as Clock Spring or Flat Spiral Spring) is a mechanical part consisting of a flat strip of metal or wire that is wound in a flat spiral around an axis. It is uniquely suited to the storage and discharge of mechanical energy in the form of rotational force, which is adaptable in the constitution of the angular movement of small objects.
Types of Spiral Spring:
Being as recommended spiral spring manufacturers in India, we provided different types of spring according to force which are given below.
Spiral Torsion Springs: This is a form of flat spiral spring, which is used to store and release rotational energy when it is twisted or wound. They are commonly applied to clockwork and rewind.
Constant Force Springs: Industrial Spiral Springs are used when it is desired to have the same level of force as the spring moves through its full range of motion or where a constant force is needed.
Power Springs: Power springs are much like constant force springs only that they are loaded with rotational force to be provided when needed.
Double Spiral Springs: Spiral Spring suppliers in India is the variation of spiral springs, but includes two spirals in them. They are available in complicated mechanical applications and equipment.
Clock Springs: A typical name of spiral torsion springs, commonly made of sheet metal, in clocks and other mechanical devices where room is a consideration.
Brush springs: Flat spiral springs are used in such devices such as the Brush.

Key Characteristics of Spiral Spring:
As recommended spiral spring suppliers in India, according to different assembly we provided different key characteristics which are given below.
Small Design: Spiral Spring dealers in India are able to hold a lot of energy in a small flat area. This renders them to be suitable in miniaturized and space-restricted electronic and mechanical assemblies.
Constant Torque: Spiral Spring manufacturers in India are designed so that they release a rotational force that is very consistent during their angular deflection. This is essential in applications where it needs constant and well flowing power.
Radial Operation: Unlike the helical springs which act in the direction of the axis the spiral springs act radially to exert pure torque. They have been designed to move in a rotary fashion.
Material Versatility: Typically produced out of high-carbon or stainless spring steel, they can be modified to be either corrosion-resistant or specific high-temperature needs.
High Precision: These demand finely tuned manufacturing tolerances in strip thickness and width in order to achieve constant performance.
Advantages of Spiral Spring:
As spiral spring dealers in India, we provided different advantages which are given below.
High Energy Density: These contain a great amount of energy storage when compared to the size of a particular object, which causes them to be extremely efficient non-electric power sources.
Effectless Process: The adequate design of the coils caused that they rarely come in contact with each other and, therefore, they have low friction thus rotate smoothly and quietly. This minimizes wear and tear on the other parts, and increases the life of systems.
Improved Durability: Spiral Spring manufacturers in India springs are highly fatigue resistant through special heat treatments and do not lose tension and shape. They are capable of operating through millions of cycles without the degradation of the material.
Integration Ease: Their planar shape can be fitted easily and easily into enclosed spring drums or housings. This simplifies the process of assembly within high volume assembly settings.
Applications of Spiral Spring
Serve as recommended spiral spring manufacturers in India, it is applicable in different sites which are given below.
Mechanical Watches & Clocks: These were utilised as the mainspring used to store the kinetic energy necessary to drive the timing gears.
Retracting Devices: The Retracting devices can be described as the rewind system in instruments such as measuring tapes and retractable cords.
Automotive Seat Adjusters: These are used in the internal reclining or locking system of passenger car seat and seat belt systems. It deploys a regulated rotational force to ensure that they remain in place or safe and controlled retractions.
Electric Motor Brushes: These are used as brush springs to provide uniform pressure on the carbon brushes within the motors or generators. Spiral Spring suppliers in India ensures constant electrical contact in order to transmit power reliably.
Circuit Breakers/ Switches: These are energy storage devices that are used to produce the high, fast switching torque required to open or close contacts fast. This guarantees high-load operation safety.

FAQs:
Ans: It accumulates and discharges rotational energy (torque) within a limited area. It is employed to perform such functions as retraction, counterbalancing, and creating movement.
Ans: It consists of a coiled strip of flat metal and made in a spiral form around an arbor. Strain causes it to tighten and it loosens up to give the stored energy.
Ans: These are capable of producing a high force output at an extremely compact, space saving design. They tend to offer almost constant drive or force throughout a brief rotation.
