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,...

Everything You Need to Know About Seat Belts Springs: 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,...

Facteurs affectant la rupture des ressorts moteurs: 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...

Design technology of high precision spring: Spring to ensure good elastic performance, that is, absorb a lot of elastic energy without plastic deformation; Sufficient plasticity and toughness to prevent impact fracture.

According to the shape, it can be divided into dish spring, ring spring, plate spring, spiral spring and truncated cone scroll spring. The design process of spring has the following points: 1. 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...

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...

How to choose double torsion springs suppliers, what is double torsion springs: 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...

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...

Application de Power Spring dans une station-service: The gas station is a familiar place for everyone. Do you find that the lines of the gas gun are all exposed when passing through the gas station or entering the gas station to refuel? They look messy and unsafe. The car needs to refuel, so you have to go to the gas station to refuel. With the continuous growth of car owners, the passenger flow of gas stations is also increasing. Have you seen the news of the gas station explosion? After a car in a gas station was refueled, due to the negligence of the Refueller, the Refueller did not take out the refuelling gun from the fuel tank port, and the driver of the owner did not check the surrounding conditions of the car, so he started the car. Then the car drove the refueling gun and oil line, pulled down the refueling end connected with it, and caused an explosion. This kind of news is very sad. Once an explosion accident occurs in the gas station, it may cause the explosion of the whole oil tank in the station. Its power is very huge, and the personnel in a certain range around may be seriously threatened. It is understood that the lines of gas guns in foreign gas stations use money collection devices. Now there are a small number of applications in China. At present, there is no large-scale application in gas stations. It uses the characteristics of winding up. It can bring a free contraction process to the line group, and make its winding easier...

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. Hand power generation is a green way of energy supply. The generator powered by the radio contains a constant torque spring motor. When tightening the spring, the spring is gradually wound onto the larger drum, and the mechanical energy obtained during winding is converted into potential energy and stored in the spring. When the spring is released, the stored energy passes through the gear transmission device and the rotating motor to generate output voltage, which is then adjusted by the zener diode to supply power to the radio in the form of a plug. Constant torque spring motor is a prestressed spring material belt, which forms a coil and is stored on a small storage drum. Then fix the free end and wind it back to the larger output drum; This is the "winding" part of the constant torque spring cycle. When the output drum is released, the spring will return to the storage drum to present its natural curvature, rotating the output drum and providing almost constant torque. When the spring is coiled around a smaller storage drum, a constant torque spring motor is formed. The terminal is then rewound and secured to a larger output drum. The spring part on the output drum is called the "winding part", and you can assemble the spring into a single or multiple configurations.The function...

Variable Force Springs In New Point Of Purchase Display: Automatic advance shelves are more widely used in stores and people's lives, and are more often used for displaying and placing goods (incense hata, rosemary, etc.). However, the conventional shelf propeller has one end of the baffle on both sides fixed and the other end movable. Although in use, after the first row of goods is taken away, the second row of goods will be automatically pushed to the first row, which can save the staff's finishing time, but in the process of pushing the goods, it is easy to cause the goods in the back row to pop out of the display slot due to the activity of the ends of the shelf advancer on both sides of the stopper, which brings inconvenience to the use. To provide a new type of shelf propeller for the problem of the shortcomings of the existing technology. The new shelf propeller includes a base plate, a side plate, a push plate and a baffle plate, the base plate, the side plate, the push plate and the baffle plate are enclosed to form a shelf slot for placing goods.

Does your nail gun have the problem of not hitting the nail?: Because there is no tension in the constant force spring that pushes the nail, naturally, no nail can be driven. The pushing device of the nail gun uses the constant force spring, because the constant force spring has the characteristic of keeping the constant force in the long stroke, and it can achieve a very high elasticity output in a very small device space. The constant force spring in the nail gun cannot be pushed too small, otherwise it will be difficult to drive the nail inside into the substrate, but it cannot be too large either, otherwise the substrate will be damaged and cracked. So when it comes to choosing constant force springs, choose a spring manufacturer with good quality. More info： www.qianyespring.com E-mail: cici_cao@qianyejm.com Whatsapp: +86-183 7490 5808

Application of constant force spring in lifting window: 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 d'un ressort de balai de charbon dans un porte-balai à bague collectrice d'éolienne: 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...
