Fattori che influenzano la rottura delle molle di potenza
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...

Come determinare la lunghezza di una molla a forza costante
  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...

 Power springs used in recoil start systems
Power springs used in recoil start systems

Ora: 14-9-2022

 Small engines are well known and are commonly used in lawn mowers and garden tractors and various other garden and lawn maintenance tools, in addition to other environments. Typically, each of these engines is equipped with a recoil starting system that includes a rope that rotates the starting mechanism to engage a flywheel that is connected to the engine for starting purposes. Once the rope starter is pulled, the recoil mechanism is always provided with the engine to reel the starter rope back to the starting mechanism.   The recoil portion of the starter mechanism is operated by a power spring that tensions when the operator pulls on the starter rope. Once the rope is fully pulled, the operator releases it. Most power springs on the market often fail, so the recoil rewinding mechanism needs to be disassembled and the spring replaced. And replacing the spring is a tedious task because the operator needs to keep the spring in the cavity inside the recoil starter pulley and then coil the spring into the pulley mechanism while keeping the spring in the coiled position and under sufficient tension. Such a procedure requires not only skill, but sometimes infinite patience. That's why the quality of the power spring is a top priority - after all, no one wants to change the power spring inside too often.   Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 20 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable...

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...
 The Advantages of Torsion Springs over Other Spring Types
The Advantages of Torsion Springs over Other Spring Types

Time:2023-3-22

Springs are essential components in many mechanical systems, serving to store and release energy in response to applied forces or changes in position. There are various types of springs available, including compression springs, extension springs, and torsion springs. In this article, we will focus on the advantages of torsion springs over other spring types.   What are Torsion Springs?   Torsion springs are a type of helical spring that exert torque or rotational force when twisted. They work by storing mechanical energy when twisted, which can be released when the torque is released. Torsion springs are commonly used in a wide range of applications, including garage doors, clothespins, and balance scales.   Advantages of Torsion Springs:   Greater Load-Bearing Capacity: Torsion springs have a greater load-bearing capacity than other spring types. This is because the load is distributed more evenly across the coils, allowing for greater force to be applied without causing damage to the spring. The ability to withstand higher loads makes torsion springs an excellent choice for heavy-duty applications.     Compact Size: Another advantage of torsion springs is their compact size. Torsion springs can store a considerable amount of energy in a small space, making them ideal for applications where space is limited. This is because torsion springs store energy by twisting, rather than compressing or extending, which means they do not require as much space as other spring types.   Greater Durability: Torsion springs are also more durable than other spring types. This is because they are typically made from high-quality materials that are resistant to...
 Application of constant force spring in lifting window
Application of constant force spring in lifting window

Ora: 14-9-2022

The lifting window is different from the traditional internal opening, external opening and ordinary push-pull mode, but adopts the opening mode of lifting up and down. Because it is mainly popular in North America, it is also called American lifting window. It is one of the two major door and window categories in the world. The lifting window is more compact than the left and right lifting windows, which is determined by the structure of the window. The traditional lifting window is a sash frame structure, that is, when the window sash is opened left and right, it is realized by sliding the lower pulley on the sliding rail of the window frame. However, there is a gap between the pulley and the slide rail, and the smoothness of the opening must be taken into account, which will inevitably lead to the decline of the sealing performance. The lifting window is a frame-encased sash structure. The sash is wrapped in the window frame and runs vertically up and down. Through the multiple seals of high-quality siliconized tops, the sash frame is tightly fitted around it, and the sealing performance is significantly better than that of the left and right lifting windows, second only to Fixed and casement windows.       The advantages of the sliding doors and windows are: 1. The characteristics of large ventilation, the lifting windows can be opened by 2/1, and the air entering the room can be convected. The European-style lifting windows and casement windows basically cannot open more than half of the area. Second, there can be different...

Application of constant force spring in refrigerator door

Ora: 14-9-2022

In order to make the refrigerator operate effectively, the door should be kept closed. Keep the door open for a short time when putting or taking out food. However, opening it for a long time will affect its cooling and endanger food safety. It will also lead to excess power consumption. Fortunately, the modern refrigerator door can be added with a constant force spring to automatically close after you open the refrigerator for use. Nowadays, this kind of design is relatively rare in the market. It is generally a magnetic refrigerator door, which explains why the magnet is attached to it.   We have seen that it is essential to keep the refrigerator door closed all the time. If the door remains open for a long time, it will counteract the internal temperature balance and affect the quality of the food stored in it.When this situation continues for a long time, the compressor cannot maintain a low internal temperature. This undermines its operational efficiency. In addition, the longer the door is opened, the hotter the inside of the refrigerator will become.   Because it is very important to keep the door closed, a constant force spring is added to the refrigerator door. If you open them, they will close automatically.A constant force spring is added, which pulls the door back and seals it tightly to the frame when the door is opened. Constant force springs are often the best spring type for this application and can be manipulated in a number of ways to ensure your design works. Constant force springs are characterized by a...

Leisure, shopping traditional products only meet material needs, people began to pursue diversified products. Let me feel deeper, such as display lifting design, this design to work and life has brought a lot of convenience. The reason why the display can rise and fall is the internal use of constant force spring free lifting principle, designed to adjust the display height of the elevator. With the help of the spring tension, the height can be freely adjusted. Compared with the traditional manual adjustment, the spring is simpler to use and more convenient to operate. The constant force spring is made of stainless steel strip. The high-strength steel strip is shaped by a specific production spring equipment. When the external force straightens it, the hair will naturally roll back and generate elasticity. However, to achieve our goal, we can return to the starting point after displacement. The advantages of the Qianye constant force spring over the traditional wire spring are: 1. In a very small installation space, a very high elastic output can be achieved. 2. A constant spring force is maintained throughout all strokes. 3. The pre-force stroke is short, and only a short stroke is needed to achieve the required elastic force. 4. The original length is smaller than the wire spring, and the stroke is unlimited. In general company venues, a large amount of information and materials need to be processed in the meeting, and different people...
