파워 스프링의 파열에 영향을 미치는 요인
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...

The reason why the world we live in is so orderly is that there are precise links between large and small objects. So many things in life are crucial. Whether they are large or small, they are indispensable to our life, but some small parts in life are unknown, but there are tens of thousands of them. The spring I know is also one of them. It always exists in a position that people can't see and does their own thing silently. Moreover, he exists everywhere in life, even if we don't know it. Today, I will explain the functions of these small springs. Spring is a kind of mechanical part that uses elasticity to work. Generally made of spring steel. Although the spring is small, as a general basic part, it has large quantity, wide range and complex varieties. It is used to control the movement of mechanical parts, mitigate impact or vibration, store energy, measure the size of...

What is passivation? Does my product need it?
What is passivation? Does my product need it?
 "My new stainless steel product specification requires' passivation '. Do I need it?" Our answer is that you may not. That's why. Passivation is the process of protecting stainless steel from corrosion by adding an oxide layer on its outer surface. Although some stainless steel product specifications require passivation to reduce corrosion risk, most of them are unnecessary and expensive, and may damage some metal products, including flat bar springs, such as constant force, variable force and constant torque springs, all of which are uncommon products manufactured by Qianye precision.     The reason passivation is not a good idea for flat bar springs is because passivation involves the use of acids and harsh chemicals to initially clean the metal as part of the process. The geometry of these spring types means that many small cracks can form between the coil layers. The acid used in passivation can become trapped in these crevices. This resulted in longer-than-expected exposure of the...

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...

 When powered by a damped constant force spring mounted on the spool, there are several key principles that influence the design of linear motion applications. These principles support robust and consistent performance of products in a variety of applications, including automotive and aircraft interiors, industrial machine components, and many other user interface applications. The example components shown above will be cited as examples of the various design principles detailed below. This example assembly has a sliding drawer (shown in red) powered by a constant force spring mounted on a spool (spool in green; constant force spring shown in yellow) running within a mounting base (shown in grey), such as a central Console a car. A ratchet or door latch mechanism (not shown) can be implemented to allow the tray to be locked in place with a single press by the user. This example is a typical set of applications used in the automotive industry.        1. Preload spring        When a constant force spring is in its free state, it does not exert any force. As the spring stretches, the spring force rapidly increases from zero to nominal load. However, to avoid including this "accelerated" part of the work envelope, the design can use preloading. An example of preloading is shown in the figure below. Note that although the mechanism is retracted, the depicted spring is extended.        To include preload in the design, ensure that the spring extends a distance equal to the outer diameter of the coil during assembly in order to engage...

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...

Supermarkets and convenience stores can be seen everywhere. Now more and more people are developing retail. Traditionally, products on shelves are usually placed in order. Some merchants install automatic propellers. After customers buy products, the propellers will push The products at the back are automatically advanced, and when the customer wants to find this product, it is easier to see, which is convenient for the customer to find the desired product and stimulates the customer's desire to buy. Theft of small items in retail stores is a problem that occurs. An ideal form of anti-theft is to create time delays between the dispensing of multiple products. If there is a considerable delay between the distribution of individual products, thieves are less likely to steal the products.        A shelf-delayed pusher equipped with variable force springs can eliminate this problem. The propulsion system includes a pusher, a track and a stop mechanism. The propulsion system includes a resistance mechanism connected to the track and the pusher, and controls the forward movement of the pusher along the track, thereby controlling the speed at which the product is propelled for retrieval by the consumer. When engaged, the stop mechanism prevents the pusher from advancing the product, and the indexing mechanism also limits the forward travel of the pusher to a discrete distance.        The variable force spring can expand the negative gradient and the positive gradient into a spring. It breaks through the influence of the traditional spring affected by Hooke's law, so that the stroke and force are...
 Application of power spring in electric vehicle charging station
Application of power spring in electric vehicle charging station

시간:2022-9-14

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. It makes it easier for users to return the charging cable to the charging station after charging the vehicle, which ensures that the...
 Design steps of constant torque spring
Design steps of constant torque spring

Time:2022-9-15

Constant torque spring is a constant force spring with special force moving between two spools. The spring is stored on the storage spool and wound reversely on the output spool. When released, torque is obtained from the output spool when the spring returns to its natural curvature on the storage spool. The spring does not need to be connected to the storage spool. The spring can be installed in a cavity without storing the spool at all. However, friction will then be introduced and torque requirements will change. The torque generated by the constant torque spring will increase slightly after several revolutions. Constant torque, even negative torque, is also possible. Negative gradients of up to 50% can be achieved in some applications. As for the design of constant torque spring, when considering the use of constant torque spring, it is strongly recommended that you talk with Qianye engineers and study various design parameters. Some initial design calculations can be carried out according to the following eight steps. 1. Select materials Most of the springs we produce are made of type 301 stainless steel. This material is readily available and predictable. Thousands of industry engineers can assist in selecting standard sizes to speed up the process. We also use high carbon steel, Inconel and Elgiloy in various designs as needed. 2. Life expectancy This is one of the most important considerations because the life of constant torque springs is very predictable. Practical is important because it is estimated that high life cycle requirements may lead to larger and more expensive designs. Of...
 Motor brush spring and wind turbine maintenance
Motor brush spring and wind turbine maintenance

시간:2022-9-14

Research shows that to get the greatest return from turbines, whether onshore or offshore, the bigger the turbine, the better. Wind turbines have proven to produce reliable and pollution-free energy, and as technology innovates, the cost of developing and manufacturing them will only become more affordable.  Motor Brush Materials and Wind Turbine Maintenance     Motor brushes are consumables, which means there is significant wear and tear over time and will need to be replaced. While proper wind turbine operation and maintenance requires moderate wear, excessive wear can create carbon dust in the slip ring cabinet, reducing internal isolation.      Also, a useful tip to keep in mind is that motor brushes that are evenly worn indicate good performance. Since reliability is critical in wind applications that generate electricity for industrial tasks and homes, businesses and schools, it is important to work closely with your engineers and parts manufacturers to determine the best motor brush materials. Two common options include: Copper carbon brushes are very common and affordable. They can be used for up to two years, but due to the high amount of carbon dust, they need a lot of maintenance. On the other hand, silver motor brushes are more expensive, but cleaner, can withstand harsh weather, and can be used for up to five years. Slip ring compatibility and design is another component to consider. Although there is wear, your motor brush must maintain a stable surface finish to avoid overtime affecting the performance of the brush. Due to the high cost of repair or replacement of wind...
 Custom springs for medical devices
Custom springs for medical devices

시간:2022-9-14

For most of the past two decades, the medical device industry has been booming. Healthcare research has led to the rapid expansion of specific devices used to treat medical needs, from rare to common. These devices range from simple to surprisingly complex, often including automatic sensors, computer monitoring, and even remote monitoring by healthcare providers. When you are designing for a new medical device, it is essential to consider the components you must put together and the system they will create. This means breaking down your design to a level where you can visualize the components that need to go into the project. This means designing each spring assembly individually after evaluating the available options. To help you solve this problem, here are the four most commonly used springs for medical devices and their current common applications.    Constant force springs Constant force springs provide a smooth range of motion and a constant load in either extending or retracting direction. This spring design has no inertia to overcome when considering the initial position forces. Constant force springs are compact and mount easily to existing hardware. These types of springs can eliminate the need for costly and complicated motors, thus decreasing device size and cost.   Spiral torsion springs Spiral torsion springs are normally used in applications requiring less than 360 degrees of rotation. They are generally used to obtain a large amount of torque through a small amount of rotation. Spiral torsion springs allow for rotation in two directions and a “return to center” capability, like a dental X-ray head unit.   Spring reels Spring powered...
