The power spring is made of stainless steel strip. A spring box is required to limit its outer diameter. The spring center is connected with the shaft. When an external force is applied to make the shaft rotate relative to the spring, the spring will roll on the shaft center and store the torque. When the external force disappears, the spring will produce the torque on the shaft or spring box.     The advantage of power spring is that it can be divided into natural power spring and pre force power spring according to its relaxed shape. In contrast, the preloaded power spring can store 25% to 55% more torque and provide more effective turns. Power springs are mainly used in products such as clockwork toys, timers and automatic rewinding devices (such as power cord, dog puller, pipe winder and automobile safety belt)     It is often seen that the scroll spring purchased will break soon after it...
How to make the constant force spring produce more force
How to make the constant force spring produce more force
A common way to install a constant force spring is to use two or more springs to obtain greater force in a narrow space. This may be necessary if the diameter or width of a single spring exceeds the allocated space, but there is room to add multiple smaller springs. When engaging multiple springs, a much smaller spring design can be used. The total force is the sum of the spring forces.       When combining springs, it is recommended to use the same spring for multiple installation. Compared with using two or more completely different springs to realize the load, this method is more economical and the design will be simpler. Since the force is the sum of the springs, the total force required should be evenly distributed between the number of springs used. We will discuss three different mounting methods for use with multiple springs.         1、 Back to back method The back-to-back method uses two...

How to determine the length of a constant force spring
How to determine the length of a constant force spring
  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 is stretched, compressed, or rotated, it produces a force proportional to its stretch. How a spring responds when a force is applied or released is called spring deflection. Years of experience tell us what happens when a spring is released from its temporary state. We know that the spring will return to its original position, but it will be proportional to the force exerted on it before releasing. A spring has a restoring force that allows the elastic material to return to its original state - the equilibrium position after the applied force is removed. Stretching, squeezing or twisting, what...

 Physical principle behind constant force spring
Physical principle behind constant force spring

When you walk into your office building on your way to work every day, or into your local bank, or any commercial facility, you may open a heavy glass door. When you cross the threshold, the door closes behind you, and you don't think about it. However, the heavy glass door was probably closed by a constant force spring. Constant force springs are widely used in daily applications. From door closers to rope and hose retractors, to sports equipment, toys, motors, etc., constant force springs exert force at an amazing high frequency and consistency. Let's take a closer look at the basic physics behind the constant force spring. In the 17th century, the British physicist Robert Hooke proposed a formula for force and elasticity, which is now called Hooke's law. Hooke's law states that the force (f) required to stretch or compress a spring for a distance (x) varies linearly in proportion to that distance. The formula is f=kx, where k is a constant and represents the stiffness of the spring.   Constant force springs in terms of actual spring performance, Hooke's law is nominal. In the equation, the distance X that the spring moves is a relatively small number. Finally, any elastomer that is stretched or compressed beyond the stress limit of its material composition will show signs of deformation. Therefore, the force properties that depend on the consistent shape and tension state will change in the deformation state. Ideally,constant force springs will exert a consistent force over a given range of motion, repeating without changing. In fact, constant force springs, like all elastomers, are limited...

A torsion spring is a coil spring that stores and releases angular energy or holds a mechanism in place. They feature two legs extending from each end of the coil and are used in applications requiring torque or rotational force. This is accomplished by attaching the legs to external components. Then, as the elements rotate around the spring, the spring tries to push them back to their original position. Torsion springs come in a variety of different shapes and sizes, with different leg configurations and lengths, for a wide range of applications. Typical uses include automotive door handles, garage doors, clothespins, bulldog clips and hinges. In some cases, a single torsion spring cannot exert enough force. In these cases, a double torsion spring may be required.     What is a double torsion spring? As the name implies, a double torsion spring is characterized by two torsion spring coils joined at the center to form one spring. The two coils are made of a wire wound in opposite directions, one counterclockwise and the other clockwise. The two parts work in parallel, like a torsion spring, with the spring legs normally pressing against the outer assembly, which pushes the outer assembly back, creating resistance. The shaft or rod usually passes through the center of the two coil bodies.   Dual torsion springs are stronger than single torsion springs and can apply more force. The resulting force is equal to that of two separate springs combined. Depending on the application, the bridge and legs connecting the two coils can be made in...

Smooth Range of Motion: Constant Force Springs Constant force springs provide a smooth range of motion and constant load, meaning they do not follow Hooke’s law. They are uniform in length and coiled into a permanent diameter. Constant force springs are frequently used for applications that require counterbalancing, including windows. In fact, window balance springs are one of our most successful products. In addition, the springs we manufacture are often designed for medical devices and aerospace applications. Their smooth range and steady motion control enhance instrument articulation.   High Torque with Little Rotation: Spiral Torsion Springs Spiral torsion springs are another popular product we manufacture.These springs are ideal for applications that require high torque and less than 360 degrees of rotation. (270 degrees maximum is preferred). Spiral torsion springs are commonly used in applications that require a “return to center” function, like a medical instrument joystick. They’re also ideal for electric motors and automotive applications. If your application requires this “return to center” function, developing a custom spiral torsion spring may be the best solution. Torque with Significant Rotation: Power Springs Power springs (also referred to as clock springs) are appropriately named due to their rotational energy that takes the form of torque. The torque increases as the spring is wound tighter. They are wound around an arbor or shaft and are retained in a housing. Their large rotation capabilities make them an ideal spring for a number of automotive applications or medical devices. Power springs are also frequently used for counterbalance mechanisms in industrial sectors.

   Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while pre-stressed power springs use pre-stressed steel to produce a larger range of usable torque than conventional power springs.        During the manufacturing process, the spring is wound into the retaining ring or the customer's housing (the retaining ring is pictured below). When ready for final installation, carefully install the spring into its housing with the outer end attached to the outer edge and the inner end attached to the mandrel (see photo below). During operation, the housing or mandrel will be fixed while the other component is free to rotate. Depending on the requirements of your specific design, it may be beneficial to use a fixed mandrel/free box or free box/fixed mandrel arrangement.        These springs are typically used to retract the cord or cable of the spool. You might see it in lawn mowers, retractable lanyards, or dog leashes. This is also the type of spring used to drive many mechanical clocks and timers, which is why they are sometimes called "clock springs". The load provided by the spring increases with the cross-sectional area of ​​the material. The number of turns the spring can provide depends on the space available between the mandrel and the...

As everyone who knows our company knows, our company also has another product, that is, dog walker! The power spring is the core and main component of the dog walker. The power spring is made of 301 stainless steel with high precision and high hardness. Its thickness tolerance is controlled in the range of 0.01mm and its hardness is hv580 degrees. The service life of the dog walker can be extended to 30000 to 100000 times. When this power spring is applied to the dog walker, the quality of the dog walker has been greatly improved. When walking the dog, we need to pay attention to bring the dog's little partner - the dog walker, and then the obedient dog should also bring the dog walker. Don't expect the bridge section of the dog looking for the master in the movie to happen. Before using this kind of traction rope, I always used a fixed 1.5m long rope. Usually I use the traction rope to prevent dogs from running around and attacking pedestrians. But there was once a time when walking a dog. Now many shared bicycles and electric vehicles often shuttle back and forth at a fast speed when walking around the corner. An electric motorcycle brushed past the dog. Fortunately, after the rope was shortened, it was able to effectively protect the dog and prevent accidents. However, many friends would say that it would be good to buy a shorter rope? But in fact, many times we need to give dogs enough range of activities, so this time can reflect...
