Constant Force Springs Design Guide

Тиме:2022-9-14

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...

Do you know how clockwork toys work?

Time:2023-3-6

Clockwork toys use constant torsion springs made of stainless steel coils. An external force rewinds the spring to the output wheel (energy storage) from its natural state. When the force is removed, the spring returns to its natural state. At the same time, a constant torque (stored elasticity) is generated (released) at the output wheel, hence the term constant torque spring. The torque is greatest when the barrel is fully wound so that the front end of the barrel needs to be output with less force. After a certain period of time, the winder, which is tightly coiled on the winding shaft, will slowly unwind and its energy will drop. When the energy is about to be exhausted, the torque at the end of the barrel is at its minimum and the force output is then reduced. Thus, the driving force needs to be increased to keep the movement running. This is why constant torque springs are so suitable for wind-up toys.

Torsion springs: where are they used and why did you choose to utilize them?

Time:2022-12-1

There are many types of springs, but the most common are torsion springs. The design of torsion springs is optimized to maintain maximum rotational pressure between two surfaces, these helical or helical springs are usually adhered to the coils at both suspended ends. These ends are connected to external components, which are then rotated to apply bending stress. Unlike other springs, torsion springs are ideally balanced and able to withstand twisting, giving them a place in many industries. Made of various coated metals such as stainless steel, carbon, titanium, nickel or copper alloys, torsion springs are usually wound around a shaft to further increase its stability. The basic principle of a torsion spring is to retain energy as the spring assembly twists. When this is applied, torque is applied in the opposite direction to the deformation angle. This allows energy to be stored and released when necessary, and the torsion spring also secures the mechanism when necessary.       Torsion springs are used in many applications; especially those using pop-up styles. They are used in various clamps and specific door mechanisms such as those found in CD players. One of the most obvious uses of torsion springs is undoubtedly in a mousetrap, which relies entirely on a centrally located torsion spring. They also sit in the center of traditional clothing clips. They are also used in heavier cases such as garage door balancers or car trunk opening mechanisms. Even in ancient times, primitive torsion springs were used as part of the giant catapults (or trebuchets) that were later used...

Да ли сте знали да је за решавање проблема паркирања бицикала потребна само једна опруга?

Тиме:2022-9-14

 Nowadays, the quality of life is getting higher and higher. Bicycle no longer exists as a means of transportation, but has become a fashionable fitness product. People who play with cars have a saying: if you want to keep your car, you don't need a car lock. Where do you put your car when you get home? Especially for people like me, who have two children and are very short of room, where to put the bike at home has become a headache.      In order to solve this problem, foreign designers have designed a parking rack, which can easily save you 40% of the use space in one step, and it is very labor-saving. The traditional hanging frame requires you to lift the car hard before you can put it on. As long as you push the hanging frame to the card slot, the hanging rack will rise automatically, and even the elderly can hang the car easily, When you need to ride, just pull your car back and the hook will fall automatically.      Of course, some people will certainly ask that there is a sensor. In fact, it is not so complex. There is a small mechanism inside and a long spring in the wall. Through the tension of the spring, your bicycle can automatically lift and lower. Some people must want to ask that a spring can be so harmful? Today brings you into the world of springs.      Spring is a kind of mechanical part that uses elasticity to work. It can...

Честитам на повратку свемирске летелице Шенџоу 13

Тиме:2022-9-14

At about 10 am on the 16th, the "Shenzhou 13" manned spacecraft landed smoothly, and the three astronauts who had been on a business trip for half a year also returned safely, and the hearts of many people also fell to the ground. At the same time, Yang Liwei's voice that appeared in the live broadcast room also made many people's soul wear 2003. Recalling that when the "Shenzhou V" was successfully launched in 2003, the first batch of post-90s generation was just thirteen years old. "Shenzhou No. 5" may already be a term with a sense of age for the late-born children of Generation Z and Generation Alpha. Mankind's curiosity and desire to conquer space have never stopped. What does the vast universe look like with human naked eyes? Is it really romantic and exciting to be in space as outlined in science fiction films? Is space really desolate and silent?      Because outer space is full of all kinds of mysteries, human beings may be afraid to see the deep universe in outer space, especially when they float in outer space when they get out of the cabin. Therefore, when the astronauts leave the cabin, they are tied to the astronauts with an 18 meter long rope and connected with an oxygen pipe to provide life support for the astronauts. If the astronauts do not grasp and drift, they can use this rope to return to the space station. Fortunately, our Qianye precision has also made a small contribution to the national aerospace industry. We are mainly involved in...

Application of variable force springs in fireplace up-down slide door

Тиме:2022-9-14

Fireplaces are freestanding or wall-mounted indoor heating devices, powered by combustible materials, with internal chimneys, originating from Western homes or palace heating facilities. Because its fuel is a renewable resource, modernized and improved, it is still commonly used in the West, and is especially popular among the higher education class, which advocates environmental protection. Fireplaces can also be installed in ordinary homes, and are perfectly achievable for small flats. The fireplace in modern homes is certainly not the firewood burning in the living room of a large villa that we see in the movies and TV, burning a fire and emitting the sound of a "blazing" star.   In colder climates, the fireplace has always been the main feature of a home, as it gives people warmth to survive the long winter hands. The feeling of warmth from the baking, and the jumping and flickering flames, even today, still make people feel happy in cold weather. The warmth of a fireplace is incomparable to that of an air conditioner, and I'm not talking about the psychological effect, which is in fact the case. Compared to air conditioners, fireplaces heat up quickly and the warmth of a real fire is comforting and relaxing. The variable force springs used in the fireplace up-down sliding doors because when the door is closed, the spring force is less than the weight of door; while the door in middle stroke, the spring force is equal to the door weight. When fully open, the spring exerts force greater than the door weight to secure the door does not...

Примена опруге константног момента у 3Д штампачу

Тиме:2022-9-14

3D printing, also known as three-dimensional printing, is a kind of rapid prototyping technology. It uses adhesive materials such as powdered metal or plastic to construct zero objects through multi-layer printing layer by layer. Mold making, industrial design is used to build models, and is now developing into product manufacturing, forming "direct digital manufacturing". Some high-value applications (such as hips or teeth, or aircraft parts) already have printed parts. The constant torque spring is applied to the 3D printer. This innovative case is a spring motor drive system. Like the common design, it is impossible for a spring to achieve the torque we need. As you can see we are using three constant torque springs in one mechanism with an output drum in the middle connecting the three springs. Therefore, it can generate three times the output torque of only one spring, and this design can achieve the purpose of providing maximum torque in a limited space. This connection method is easier to assemble than using screw connections.        When it comes to spring design, design engineers must consider many factors. These factors include not only part function and mechanism design, but also detailed material selection, part connection installation method and size. It's all about manufacturability. Feasibility analysis is required to ensure the functionality meets the customer's needs.        From the initial design stage of the spring set to production and final assembly, Qianye can save customers product development time, find optimized solutions beyond your expectations, no manufacturability constraints in product design, and the best product...

Do you have this problem when designing cordless blinds?

Time:2023-3-6

When the curtain is pulled to the top it sags and when it is pulled to the bottom it springs back a certain height.   Qianye Spring Company has succeeded in developing this cordless blinds spring. The steps in the design of a cordless curtain spring are as follows. 1. Determining the size of the winding spring force It is usually necessary to determine the weight of the curtain. It is usually possible to measure the force required to hold the cordless curtain at the top and to measure the force required to hold the cordless curtain at the bottom.   Determining the spring life It is usually necessary to determine the duration of use of the curtain. For example, a spring with a life of 8,000 strokes will not loosen or deform within the life of the spring.   Determining the space in which the spring is to be installed The space where the spring is to be placed, the distance between the two springs, the outer diameter of the spring, etc. should be taken into account.   4. Adjustment of the curtain spring after trial This stage is usually the adjustment of the force. For example, increasing the force of the spring at the beginning or decreasing the force of the spring at the end.   More info： www.qianyespring.com https://qyspring.net/ E-mail: sales@qianyejm.com Whatsapp: +86-183 7490 5808
