How to determine the length of a constant force spring
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...
Constant Force Springs Design Guide
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...
Design of constant force springs
Design of constant force springs
 A constant force spring is a spring that exerts a constant force over its range of motion. That is, it does not obey Hooke's law. Typically, a constant force spring is constructed as a coiled band of spring steel so that the spring relaxes when fully coiled. When it is unrolled, the restoring force comes mainly from the portion of the belt that is close to the roll. Since the geometry of this region remains nearly constant as the spring unfolds, the resultant force is nearly constant.       By creating a spring with a variable pitch, you can make a push-shape spring with a constant velocity. Placing a larger pitch in a larger outer diameter coil and a smaller pitch in a smaller outer diameter coil will force the single spring to fold all coils at the same rate when compressed.       Design of Constant Force Springs: A constant force spring is a coil of prestressed...

Variable force springs are very common in the point-of-purchase or POP industry, especially in shelf pushers. Variable force springs provide variable force to precisely match increasing or decreasing force requirements, propelling the product horizontally forward. Due to their wide applicability, these springs can be seen in the tobacco, cosmetic, electronics and medical industries. So why use variable force springs in shelf thrusters?       1. Inventory Control        Variable force springs are commonly used in trays that push products forward in a controlled manner. Variable-force springs in the push-in trays aid product fronts, so the shelves are always well-stocked. These trays allow for more organized store inventory and help track inventory needs. This is even more critical in today's COVID-conscious environment.         2. Product Integrity        Variable force springs are designed around the weight of the product they push. This ensures that the product is never slammed or damaged when it is...

All curtain cords, whether installed on the side, caught in curtains, or placed on the back, can be dangerous to children. It is best to replace all corded curtains with cordless curtains in houses where children live or visit, especially in children's bedrooms and play areas. Cordless roller blinds with either a spring system or an electric system can improve the safety of the home.        Cordless roller blinds with spring system are similar to movie curtains. They use the elasticity of the springs. Under the action of the spring components, the roller blinds can be balanced at any position and can be stopped at any time.        At present, most of the spring components on the market are wire spring cordless curtain systems, which have a relatively short service life and a high degree of force attenuation. When pulling down, the curtain stops at each clip, and when rising, pulling down makes the curtain bounce...

The roller blinds are blackout roller blinds, soft yarn roller blinds, and Shangri-La roller blinds in appearance. They are mainly corded and cordless. Roller shutters have many advantages such as beautiful and simple appearance, firm and durable structure, etc. Roller shutters are suitable for various places, especially for large-area glass curtain walls. When the roller blind fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good shading effect. When the roller blind is raised, its volume is very small, so that it is not easy to be detected.        The bead roller blinds use the rope or chain to ascend and descend. The biggest problem of the rope/bead system is that the curtain will not be pulled when it is too big, and the rope will easily break. It is not very convenient to use, and the rope is easy to get dirty. It is very dangerous for...

 What is passivation? Does my product need it?
What is passivation? Does my product need it?

Время:2022-9-14

 "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 stainless steel, which in turn resulted in hydrogen embrittlement and eventual spring failure. Additionally, mechanically exposing all surfaces of the spring to acid can damage the spring, resulting in changes in force/torque output or defects. There are better, simpler, cheaper ways to avoid any need for corrosion and passivation of stainless steel components, and it's as simple as choosing a fussy material. Remember that the risk of corrosion of any stainless steel component is driven by the environment (such as the presence of water and other chemicals) and Qianye Precision typically uses high quality 301 stainless steel for our springs....

A constant torque spring motor is a strip of prestressed spring material that forms a coil and is stored on a small storage drum. The free end is then pinned and rewound onto 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 assume its natural curvature, rotating the output drum and providing an almost constant torque.        Constant torque springs are made of type 301 high quality stainless steel and are supplied in coil form for mounting on the motor drum. Its main features are: 1. Long time deflection under almost constant torque. Positive or limited negative gradients can be achieved. 2. Minimal inter-coil friction and resulting hysteresis, which is common in power springs. 3. Rotary motion is provided directly from the output drum or linear displacement by using cables and spools.        Many applications utilize constant torque spring motors, such as: cord retractors, balance retrieval and return applications, drive motors, cordless curtains, and more. The spring features a high turn design, making it ideal for balancing applications. When they are fully turned, the springs apply a constant torque. You can also guarantee high torque levels. This is due to their compactness and high efficiency.        The function of the constant torque spring motor depends on the design. The size of the spring can vary. Therefore, they make them suitable for use in a variety of applications. We strongly recommend that you consult...

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 is applied to the product. Once the scroll spring breaks, its service life will end. If spring manufacturers choose general materials and immature production technology, the service life of products will be greatly reduced. There are many factors leading to its rupture, mainly including the following factors: wrong scheme design, shortcomings of raw materials, poor production and processing and so on. The quality of power spring determines the quality of products and user experience. Take the dog leasher with scroll spring as an example. With the increasing improvement of living standards, raising pets has become a fashion. In the process...

 Constant force spring in vehicle ashtray
Constant force spring in vehicle ashtray

Время:2022-9-14

If the plush toys in the car are the favorite of female car owners, it is believed that the favorite of male car owners is the vehicle ashtray. Car ashtrays are indispensable car supplies for smokers. Although the vehicle ashtray is specially designed for smokers' car owners, it can also be used to place sundries for non-smoking car owners, which is very practical. When it comes to car ashtrays, I have to mention the problem of smoking in the car. In fact, smoking in the car is more dangerous than smoking outside. After all, the space in the car is limited, and the air circulation range is small. In this case, smoking will certainly cause air pollution in the car.      However, at present, the utilization rate of ashtrays on many models is not very high. Most smokers' car owners pop ashtrays out of the window directly. The function of on-board pop-up ashtrays can greatly improve this situation. Now many cars have ashtrays designed under the central control and in the rear row to facilitate smokers in the car. In addition, some luxury cars also have ashtrays designed under the door handle. Most of the vehicle ashtray structures are in the shape of cylindrical cups, and the sealing performance is also relatively good. Generally, cigarette butts are thrown in. Basically, there is no smoke smell floating out, and the sealing is more humanized. Pop up ashtray riders may worry about whether the car will be a little bumpy, and the ashtray will pop up automatically. The ashtray will fly everywhere,...

Application of constant force spring in lifting window

Время:2022-9-14

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...
 The Key Role Of Motor Brush Spring In Wind-Turbine Design
The Key Role Of Motor Brush Spring In Wind-Turbine Design

Время:2022-9-14

Wind-turbines are proven to create reliable and pollution-free energy, and as technology innovates, the cost to develop and manufacturer them is only becoming more affordable. Research demonstrates that to get the most return on turbines, whether onshore or offshore: the bigger the turbine, the better. There are two reasons for this: larger rotors and blades increase the total potential production capacity of the turbine, while higher fixtures and blades are higher in the atmosphere, increasing the power it can actually produce. These two factors are the driving forces behind the efficiency of wind turbines and their ability to create renewable energy. However, in order to achieve this goal, the manufacture of wind turbines requires the use of dozens of parts, components and materials. Motor brush or carbon brush is a small and important part of wind turbine design.  An important part of wind turbine motor brush is motor brush spring. These springs play a key role in the efficient operation of wind turbine generators and are used to push the brush towards the commutator in the motor to generate friction and transfer current between the rotating part of the machine and its power supply.     For high-performance wind turbines, the brush materials (or brush grades) and components used in the manufacturing process must be of high quality. In addition to the final details required for your application, some specifications to consider when selecting motor brush springs include:     Material: stainless steel is used in most applications. Life cycle and force: the force of the spring should be equal to...
