Constant force spring is made by winding the steel strip into a coil. The stress added to the spring determines its diameter, strength, and life. The action of a constant force spring is very similar to the action of stretching a ribbon. Spring stretching and rewinding, the part of the work with the spring itself circle formed tangent, as long as the diameter of the spring is certain, the force of the spring is constant. In extremely long spring designs, varying diameters have an advantage, and the tension increases slightly as the spring is stretched. However, this increase is small relative to the length of the stretch and can be ignored in many applications.Constant force spring is made by winding the steel strip into a coil.

According to the application principle of constant force springsconstant force springs can be divided into linear motion constant force springs and rotary motion constant torque springs. When linearly stretched: the unit of force value is: kilogram, newton, pound, etc.

        Constant force spring has the characteristic of maintaining constant force during long stroke. Its function can be used in LED computer screen and fan height adjustment, store display rack or nail gun push device, etc., which need to go back and forth, slide, stretch, and return. , Balance or labor saving and other linear motion product applications.

When a constant force spring provides rotational torque, the unit is inch-pound (N-meter) and so on.
Constant torsion spring can be used for automatic winding, balancing heavy objects, power sources, such as automatic winding of power cord, Cordless curtain, generator radio and toys.

In some areas, the force of the constant force spring is required to change. As the spring stretches, the force is reduced by the negative slope (gradient) spring; as the spring is stretched, the force increases by the positive slope spring; the constant force spring includes two springs, positive slope and negative slope. Cordless curtain springs are the most common application of constant force spring with negative gradient slopes.
The application of constant force springs in product design can save space and provide sufficient force for the product. By cooperating with Qianye, you can shorten the production lead time and get high-quality and price-competitive springs.

  Constant force springs are mechanical devices used in applications that typically require some kind of balance or retraction mechanism. In design and function, constant force springs differ from the more common types of coil springs. They apply a consistent linear force or torque that remains constant over a wide range of motion. When a coil spring is under force, whether it...

The constant force spring of the industrial door mainly plays a balancing role and reduces the burden on the motor. The force of the spring is equivalent to the force of the industrial door, which is the most ideal configuration state. If the spring force is too large or too small, it will affect the operation of the industrial door....
