Power spring in the design of the car covers: Car covers are commonly used automotive protective articles, but the folding and storage of car covers is a troublesome thing. In order to solve this problem, invention lovers have done a lot of useful exploration and put forward many solutions. One kind of scheme is to use power to drive the reel to directly roll up the car cover cloth. Using the reel to directly roll up the car cover cloth can achieve the purpose of rapid retraction of the car cover, but there are the following problems in actual use: first, the winding and friction of the reel when directly rolling up the car cover cloth wear the car cover cloth greatly; second, in order to adapt to the width of the car cover cloth, the width of the car cover retracting device must be close to the width of the car cover cloth. If it is too narrow, it will increase the winding of the car cover cloth,...

Application of carbon brush spring in wind turbine slip ring brush holder: In order to prevent accidents caused by excessive wear of the carbon brushes on the collector device of the slip ring brush holder of the wind turbine, a normally closed switch-type alarm unit is configured for each carbon brush, and these alarm units are connected in series to the alarm. In the prior art, the grounding brush is held on the structure using a coil spring pressure finger lever structure. In order to ensure sufficient pressure after the carbon brush is worn, the initial pressure of the spring has to be increased, which aggravates the wear of the carbon brush. However, in the later stage of carbon brush wear, the tension of the coil spring becomes insufficient again, resulting in poor contact between the carbon brush and the slip ring, frequent beating, resulting in breakage; at the same time, from the carbon brush to the alarm unit, the intermediate link is complex and easy to Lead to false alarm or no alarm, reducing the...

Application of constant torque spring in wireless radio: With the increasing attention of human beings to environmental issues in the process of social progress, green and low-carbon has become a popular new trend, and energy-saving and environmental protection technologies and products continue to emerge, which are affecting and changing our lives.

Do you know what springs are used as stop mechanisms?: We often find that the spring we make is wrongly used as a stop mechanism in the design. This design defect can occur in all types of springs, including constant force spring, constant torque spring and power spring. For example, consider a simple cable extension product in which the spring retracts the cable into the housing. If the spring is completely wound before the cable is fully deployed, the spring will be used as a stop mechanism. This action will damage the function of the spring and components and should be avoided at all costs. Here are some useful tips when considering the stop mechanism. Constant Force Spring Application: Initial designs often show the inner end of a Constant Force Spring attached to its’ spool. This is not necessary. If the spool is larger than the natural spring diameter, the spring will automatically fit tightly on the spool. In the case when a screw is attached to the spool, additional concerns arise. If the spring is pulled tight on the screw, a hump will result that will not only make the retraction difficult but will cause a fracture point and reduce life cycles. To avoid this, we recommend that the spool maintain 1-1/2 wraps of spring material at the furthest extension. If these additional wraps are not practical in the design, another method of stopping the rotation is required. Constant Torque Spring Applications: This type of motor spring is commonly used to retract a cable or to keep a constant torque rotational force on a spool. It is extremely important not...

The new computer monitor spring design offers greater durability and flexibility: Computer monitors are an essential component of any modern computing system. They allow us to see and interact with the graphical user interface that enables us to use our computers for a wide range of applications, from word processing and data analysis to gaming and entertainment. Over the years, computer monitors have undergone significant improvements in design and functionality, leading to the development of high-resolution displays, curved screens, and other features that enhance the user experience. One area where monitors have often fallen short, however, is in their durability and flexibility. Many users have experienced problems with cracked screens, broken hinges, and other hardware issues that can render their monitors unusable. To address this problem, a new spring design has been developed that offers greater durability and flexibility. The new design is based on a series of interlocking springs that are integrated into the frame of the monitor. These springs are designed to provide a level of flexibility that allows the monitor to bend and twist without breaking, while also providing a high degree of durability that makes it resistant to damage from impacts and other forms of wear and tear. The result is a monitor that can withstand a wide range of environmental conditions, from extreme temperatures to high humidity, and is less likely to suffer from the types of hardware problems that can plague traditional monitors. One of the key advantages of the new spring design is its ability to absorb shock and vibration. This is particularly important in applications where the monitor may be...

The power spring makes the tape measure shrink freely: Tape measure, I believe everyone is familiar with it. Tape measure is a common measuring tool in our daily life and work. After the tape measure is pulled out, it can be rolled up because there is a power spring in the tape measure. When pulling out to measure the length, it actually lengthens the length of the scale and spring. Once the measurement is completed, the spring in the tape measure will automatically shrink, and the tape will also shrink under the action of spring force, so the tape measure will roll up. The power spring is an elastic fitting in the tape measure. The end of the steel bar scale is connected to the front end of the spring, and the end of the spring is fixed in the middle of the tape measure. The tape measure mainly uses the energy storage characteristics of the spring, which can be said to be the conservation of mechanical energy .When you pull the tape measure, you work on the internal spring, and the energy is stored by the power spring; when you release it, the spring relaxes, releasing energy and causing the tape measure to retract automatic contraction uses the lever torque principle: in the stretching state, the force arm is the smallest and the spring output is the largest; in the retracted state, the force arm is the largest and the spring output is the smallest. When the scale is pulled out, the spring is tightened to produce a force to roll back. When the tension of the scale is released,...

[Qianye precision]Spring on motor car curtain: When taking the high-speed railway, everyone should like to look at the scenery outside the window. I don't know if you have paid attention to the curtains on the bullet train. When I take the bullet train, I often find that there is no buckle on the curtain slide rail on the bullet train, but I can still go up and down freely and won't fall or bounce back. That is to say, when I pull down 1 / 3, it will stop at 1 / 3, and when I pull down half, it will stop at half; If you want to put it away, just push it up and stop where you push it? It's different from the curtains I usually see at home. Isn't it affected by gravity? With this curiosity, let me show you that the bullet train should be a spring roller shutter. The elasticity of the spring roller shutter can adjust the rise and fall of the fabric within a certain range and can stop at any position. Gently pull down and let go. The fabric can bounce back to the top of the curtain leisurely and freely. The operation is light, the operation time is short, and the stay position is arbitrary. Compact structure, flexible and convenient operation. Because the addition of variable force spring makes the roller shutter achieve this effect, many variable force springs on the market can not achieve the effect that the force is changing in any section, so many electric roller blinds will add some components (deceleration device, damping device, this...

Una molla a coppia costante può svolgere un ruolo così importante nel dispositivo di raccolta: Constant torque springs can help take up the wire and are used in many products. All electrical products have a cord set that is connected to the power supply, but this power cord will bring some trouble to our arrangement. The function of the constant torque spring is this, it can bring a free shrinkage process to the electrical cord set , making it easy to take up the line, very practical. When the external force reverses the constant torque spring from the natural state to the output wheel, once the external force is removed, the constant torque spring will be rolled back to the natural state, and a constant torque will be generated in the output wheel at the same time. Constant torque spring can be used in automatic winding, balance weight and power source, such as automatic winding device of power line. Advantages of constant torque spring over power spring: 1. The torque will not change as the number of turns increases. 2. There is no limit on the number of available turns, and the design of multiple turns mostly adopts constant torque spring. 3.

Application of power springs in construction protective devices: With the development of society, buildings and roads are the cornerstone of the development of human society. People will choose to lay waterproof materials during waterproof maintenance, but people face some problems when laying waterproof materials. When laying waterproof materials, people inadvertently trample on the materials because they do not know that the materials have been laid, resulting in uneven laying of materials and economic losses. Therefore, we need to protect the sites under construction and just completed construction when laying. Many of the existing protective devices are large, which is not conducive to people's carrying, and the protective devices can't be seen by people at night, causing people's damage. The laying of water-proof materials is wasted, and the placement of protective devices is unbalanced, causing collapse and damage to people. The utility model relates to a wet laying waterproof coiled material construction protective device equipped with a power spring, which can solve the above problems. The power spring requires a housing to limit its outside diameter. The spring stores force during the rotation of the power spring relative to the central axis of the spring housing. When the force disappears, the power spring will produce a torque on the central shaft of the spring housing. The protective device comprises two expansion columns 1, a contraction device 21, a second fixing block 4 and two expansion columns 1, one of which is provided with a contraction device 21. The retracting device 21 is composed of two rotating discs 12, the first fixed column 13 and the power spring 14. The rotating disc 12 is installed in the...

Constant Force Springs Design Guide: There are many mechanical components to choose from for your device or application. If your device requires a spring, consider constant force springs. These are a type of extension spring. They do not obey Hooke’s law, so their force remains constant, even when deflected. Because of their flat force curve, constant force springs are suitable for applications that require a smooth range of motion and a constant load. Learn more about this type of spring to see if it could work in your device or application. Constant Force Spring Benefits There are many benefits of constant force springs that make them suitable for a number of applications: Have small space requirements Provide a smooth range of motion Have no inertia to overcome Mount to existing hardware Produce a counterbalance effect For these reasons, constant force springs are versatile enough to work for a number of applications in which a constant load is required to counterbalance, tension, retract or dispense. This is why they’re frequently used to enhance surgical devices, deploy and retract doors on aircrafts, and counterbalance windows. Design Considerations If you decide that constant force springs are ideal for your application, here are some considerations to think about in the design phase of your project. Load Conditions Constant force springs produce a force as the material is extended. Constant force springs are rated at a maximum operating length. This means that the maximum travel must be lower than the difference between the spring’s unextended length and maximum safe operating length. Material Another important design consideration is material. 301 stainless steel is commonly used for standard-issue...
