Spiral coil spring
A spiral coil spring is a type of spring made of rectangular metal strips wound into a flat spiral. These springs are designed to store and release rotational energy in the form of torque. One of the most popular types of helical springs is the constant helical spring, so named because they exert a nearly constant binding force that is resistant to expansion, so that when the bar is stretched, the inherent stress is resistant to the load at a technically constant rate.
Spiral coil spring in the process of production, will form a concentric spiral, this mechanical device by the application of rotating force to store and release energy. The torque generated per revolution is linear for the first 360°. If the deflection exceeds 360°, the coils will usually “close” or touch each other. This leads to a rapid increase in torque.
Spiral coil spring characteristics and advantages:
- Small stiffness: The stiffness of the Spiral coil spring is relatively small, suitable for working under static load.
- Storage energy: The Spiral coil spring can store more energy in a smaller volume, thanks to its flat spiral structure.
- Reliable operation: The Spiral coil spring has reliable working performance and convenient disassembly and repair, so it is widely used in many fields.
Spiral coil spring are available in a variety of materials for development projects or prototypes, including carbon steel, stainless steel and specialty alloys, each with the following unique advantages:
- Carbon steel: Carbon steel is widely used in engineering springs and may require pre-galvanized layers or additional corrosion protection.
- Stainless steel: Stainless steel has excellent heat and corrosion resistance and is an essential metal alloy for the manufacture of spiral torque springs.
- Specialty alloys: Metals such as chromium and cold-drawn nickel are best suited for applications that require high corrosion resistance at extreme temperatures.
Application of the spiral spring
Sports applications requiring short rotations use helical torsion springs, where torque is required but the number of rotations is less than three at most, usually one or fewer. They achieve large amounts of torque with less rotation than power springs and are widely used in the following industries and applications:
- Medical equipment
- aerospace
- industry
- motor
- trucking
Spiral coil spring have several advantages, these mechanical devices are very durable and have a long practical life, they are cost-effective, they are also easy to use and adjustable for use in vehicles and other applications, they are relatively small and can be installed in a variety of environments, especially where space is limited.
A Spiral coil spring is a spring made of a rectangular strip of material that is smoothly wound around itself. These springs have special fixing holes or bends at both ends that allow them to be fixed or secured in place. Then, when a force is applied to pull or extend the free end of the spring, the spring will act like a stretched spring. The torque-deflection characteristics of coil springs are usually nonlinear. This condition is caused by the friction between the coils and the change in the amount of material that becomes active when the spring deflects.
As with all of our custom springs, each Spiral coil spring we manufacture delivers high quality and reliable performance. We ensure that each spring meets the quality and tolerance requirements you set for your project.
Spiral coil spring is the same section of slender material wound into a plane spiral linear spring, its one end is fixed, the other end under the action of torque bending elastic deformation, so that the spring in its own plane torsion.
