Spiral spring design: the forgotten part of mechanical design: Spiral springs are often taken for granted in mechanical design, but they are an essential component in many applications. In fact, spiral springs can be used to achieve a wide range of motion and force characteristics, making them a versatile choice for many applications. What are spiral springs and what are they used for? Spiral springs are one of the most common types of springs. They are made from a coiled wire that is formed into a spiral shape. Spiral springs are used in a variety of applications, including automotive, industrial, and consumer products. They are used for a variety of purposes, including providing compression, tension, and torsion. The history of spiral springs The spiral spring is a unique invention that has a long and interesting history. Though the first spiral springs are believed to have been invented in China, they didn't become popular until the 1700s, when they were used in clocks and watches. In the 1800s,...

Всичко, което трябва да знаете за пружините на предпазните колани: Seat belts and springs are both important parts of a car. Seat belts keep you safe in case of an accident, while springs keep the car in shape. It's important to know how to use both of these parts properly. What are seat belts and springs, and what do they do? A seat belt is a device used to secure the occupant of a vehicle in a sitting position. A seat belt consists of two straps, one running over the shoulder and chest, the other between the legs. The purpose of a seat belt is to distribute the force of a collision over the entire body, thereby reducing the likelihood of injury. A spring is a device used to store energy and release it in a controlled manner. Springs are used in a wide variety of applications, including automotive suspensions, door hinges, and shoe laces. How do seat belts and springs work? When you press down on a seat belt,...

Фактори, влияещи върху разкъсването на силовите пружини: 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: 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...

Device space: design a compression spring, clearly understand the space required to install the spring, and then you can master the basic manufacturing conditions, outer diameter, inner diameter and free length of a compression spring. 2. Movable stroke load: the design of compression spring to clearly understand the position to be actuated and the elastic force to be carried. Determine the position and know the required elasticity, then you can determine the material, wire diameter and number of...

Как да се определи дължината на пружина с постоянна сила: 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...

Какви фактори ще повлияят пряко на използването на пружини?: A power spring is a mechanical part that uses elasticity to work.

Qianye Precision’s design on industrial doors: As the building access door of modern plant, the industrial door must be familiar to everyone. The industrial door has a variety of lifting door modes. It slides upward according to the track installed on the wall, which is fast and stable. At present, the industrial door mainly uses the torsion spring balance system to stabilize the industrial door in the process of operation, so that it can be opened quickly. Principle of torsion spring balance system: torsion spring balance is the principle that the weight of the door body is balanced by the torsion torque of the torsion spring. The torsion spring balance system of industrial doors is mainly composed of supporting seat shaft, spring, wire hub, steel wire rope and other components, in which the material of torsion spring is more important. Generally speaking, the torsion spring of the torsion spring balance system needs to be made by computer-aided design and professional equipment. Industrial door balance system analysis what are the small problems of torsion spring balance? In practice, it is difficult to meet the standard requirements due to the influence of spring material and manufacturing process. When the area and weight of the door are increased, the diameter of the torsion spring and the diameter of the steel wire will be thickened, which will affect the sensitivity of the balance of the torsion spring and increase the difficulty in adjustment. The installation of torsion spring balance on the door opening with large height width ratio increases the difficulty in designing the torsion spring balance due...

Приложение на електрическа пружина в станция за зареждане на електрически превозни средства: As the times change, gas stations are gradually replaced by electric vehicle charging stations. We have always been a natural partner for designers and manufacturers of electric vehicle charging stations, because they need to be compact, clean and provide trouble free cable management solutions for their electric vehicle charging stations around the world. By applying our power spring to the retractable cable drum, the cable wear is reduced, the tangled cable is eliminated, and the cable can be neatly stored when not in use. In this way, we help EV charging station developers shape the future of safe and trouble free charging of electric vehicles. The natural expansion trend of the power spring gives a torque to the spindle or case, resulting in a usable torque. The generated torque is cumulative, so the torque will increase as the spring is tightened and decrease as the spring is loosened. Torque and total number of turns are the most important output requirements in the design of power spring. The performance of the power spring depends on the size of the spring material (thickness, width and length) and the available space (shell and spindle diameter). Qianye precision can provide customized spring design solutions. Use our design to specify your requirements,as a spring manufacturer, our customized spring performance meets your expectations. Make the product balance various charging cables. When the user walks back to the charging end, the cable drum pulls back the middle of the charging cable.

Do you know function of the spring in fire damper?: What do you think when you see the fire damper? I believe many people will think of "fire". In fact, the word "fire" must be familiar to everyone! What do you think of when you hear this word? People trapped by the raging fire? Or the scene of our brave firefighter uncle fighting the fire? The following are the fire events in recent days. At 14:00 on March 12, 2022, a fire broke out in the oil fume pipeline of a hotel in Huazhou City. At 3:46 on March 8, 2022, a fire broke out at the construction site of Jinke Xiangsheng Yueyuan at the intersection of chegang road and Xiyun road in Zhenjiang new area. In the early morning of March 14, 2022, a fire broke out in Kundulun District of Baotou City, which has killed 7 people so far. Do you feel very sad at this time? Uncontrolled fire is always a serious risk. In an emergency situation a fire can spread via a ventilation ductwork. Therefore it is essential that the ventilation ductwork is equipped with high-quality and robust fire dampers that also prevent smoke from spreading and therefore enable safety for escape routes. But what is a fire damper? Fire Dampers are used in air transfer openings, ducts and other places where fire rated structures (e.g. walls, floors or other fire barriers) are penetrated. If these openings wouldn’t be protected, the fire would easily spread to other spaces and damage the property and pose a danger to people working/being in this environment. The idea...

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 reliability of the system. In order to overcome the shortcomings of the prior art, a novel slip ring brush holder collector of wind turbine generator with simple structure, reduced wear of grounding carbon brushes and reliable operation is provided. The slip ring brush holder collector of wind turbine includes slip ring, brush holder, main carbon brush and grounding carbon brush, and the pressure end of the grounding carbon brush with alarm pressure piece is pressed by a coiled constant pressure spring. The constant pressure spring grounding brush holder structure greatly improves the force on the carbon brush during operation and...

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, so the shape of the car cover retracting device is larger, It reduces the convenience of use: Third, it may not be able to completely stow the hood cloth. Only one power spring is needed to solve the above series of problems. The power spring designed by Qianye precision can be applied to the car cover. The power spring retracts the car cover to realize the rapid retraction of the car cover. At the same time, it solves the problems of large wear, large device shape and high operation intensity caused by the direct retraction of the car cover cloth by the reel, as well as the problem...

[Qianye precision]Physical design and recoil force of constant force spring: In most types of springs, when the spring is compressed and then relaxed, the force applied is proportional to the distance the spring is stretched. Unlike ordinary springs, constant force springs do not comply with this rule. Due to the physical design of constant force spring, its return force remains constant. Therefore, constant force springs are useful in many applications that require consistent recoil. The behavior of ordinary springs can be described by a mathematical equation called Hooke's law. The law points out that the force of the recoil spring in the recoil direction is equal to the distance between the spring displacement and the equilibrium point. In other words, it is how much the spring is elongated and multiplied by the mathematical constant, that is, the spring stiffness. The spring recoils in the direction opposite to the stretching direction. Because many elastic materials work in this way, Hooke's law has a wide range of applications in the field of physics. Hooke's law does not apply to constant force springs because their recoil force remains constant over the entire range of motion. This is achieved through its unique physical design, which consists of thin and curly steel strip. The constant force spring is in a relaxed state when it is fully rolled up, and is loaded when it is partially or fully unfolded. After release, the spring rebounds by pulling the extended carbon belt back into the tight coil. Since the recoil force mainly comes from the part closest to the coiling roll, a constant force can be maintained. Common applications of constant force...

Exposed Power Cord Solutions: As people are becoming more and more picky about the beauty of home appliances, the problems of dirt, vulnerability and difficult placement caused by the exposure of power lines have been unsatisfactory. However, with the take-up device, the wires are completely stored in the internal space after use, and these problems are solved. Its core component is the use of winding up. Take-up spring refers to a kind of rotary spring that puts the steel strip crimped once or twice into the fixed box, and then connects it through the middle mandrel to tighten it to the predetermined position. After releasing the preload when necessary, it uses the rebound force of the rolled steel strip to achieve the design purpose. The utility model has the advantages that the utility model is designed for rotary use, and can be widely used in the circular design device, and forms a coaxial design with the take-up device, which saves space very much. Under the condition of well-designed, its maximum service life can reach 300000 times. Parameters that must be provided for the design of take-up spring: 1. Inner diameter of installation box (d) 2.
