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...

 Nine factors that should be paid attention to in spring production
Nine factors that should be paid attention to in spring production

Tid: 2022-9-14

A spring is a mechanical part that works with elasticity. Generally made of spring steel. It is used to control the movement, buffering or vibration, energy storage, force measurement, etc. of mechanical parts, and is widely used in machines and instruments. (1) Elastic limit - the elastic limit is related to the tensile strength. Selecting a material with a high elastic limit is usually equivalent to selecting a material with a high tensile strength. (2) Spring coefficient - the stress applied to the spring material to produce a unit strain is called the elastic coefficient value, which mainly depends on its chemical composition.    (3) Fatigue strength - fatigue strength must be considered for springs subjected to dynamic loads.   There is a certain relationship between fatigue strength and tensile strength of materials. (4) Hardenability - in order to improve the quenching effect, the material is required to have good hardenability, and at least 50% of the central block iron structure shall be quenched. (5) Shape and size - the mechanical properties of the spring material change with the size. The manufacturing size of the spring material is allowed to have tolerances. Therefore, the material must be selected according to the accuracy of the spring load characteristics.(6) Heat resistance - some springs are used at certain high temperatures. Generally, the mechanical properties of spring materials decrease with the increase of temperature, and the spring performance decreases after a certain temperature.   (7) Corrosion resistance - when the spring is used in a corrosive environment, the corrosion resistance of the material mainly depends on its chemical composition.    There are many corrosion factors, so we...

The constant force spring of the industrial door mainly plays a balancing role and reduces the burden on the motor. The force of the spring is equivalent to the force of the industrial door, which is the most ideal configuration state. If the spring force is too large or too small, it will affect the operation of the industrial door. In severe cases, safety accidents may occur and endanger others.        Constant force springs are often used to provide balance to products, so what is balance?        Constant force springs are most useful in applications that require consistent recoil. Ordinary springs behave according to a mathematical equation called Hooke's law. Hooke's law states that the force of a recoil spring in the direction of recoil is equal to the distance the spring is displaced from equilibrium. Simply put, we look at how far the spring is stretched - multiplied by a mathematical constant, the rate of the spring. The recoil direction of the spring is opposite to the stretch direction. ,km        Hooke's Law does not affect constant force springs because their recoil remains constant throughout their range of motion. Their unique design consists of a thin, coiled steel strip that rests when fully coiled. Constant force springs are loaded when they are partially or fully deployed. When released, the spring springs back, pulling the extended ribbon back and rolling up properly. Since the recoil force is mainly obtained closest to the take-up roll, a constant force is maintained. A constant force spring can...

 I'm sure many of you know what a constant force spring is, right? A constant force spring is a spring that maintains a constant spring force for a specific stroke, also called a constant force spring, and is used in a linear motion, usually using its rebound force. A constant force spring consists of a spiral-shaped metal sheet that is bent on the inside so that each coil is wound tightly around the innermost coil of the metal sheet. When the metal sheet is stretched, the internal stress resists the load force, which is exactly the same as a normal extension spring, but the spring force is very constant and can output a nearly linear spring force.   The use of a constant force spring on the lift support enables the supported structure to hover over gravity at any position during the allowable travel.   However, in order to achieve a variety of functions and operations, the supported structure, such as a monitor, usually weighs more than the white body of the device. In order to ensure a large support force, the constant force spring needs to use a thick elastic metal sheet. However, the thick elastic metal sheet will lead to a short effective constant force spring travel.   The purpose of this constant force spring die set is to provide a constant force spring die set that is capable of maintaining a large constant force lift value and a constant force effective stroke within an effective mounting space. Another purpose is to provide a constant force spring lift mechanism that not only provides a greater constant lift force, but also reduces the mounting space of...

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...

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

Time:2022-11-21

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...

Smooth Range of Motion: Constant Force Springs Constant force springs provide a smooth range of motion and constant load, meaning they do not follow Hooke’s law. They are uniform in length and coiled into a permanent diameter. Constant force springs are frequently used for applications that require counterbalancing, including windows. In fact, window balance springs are one of our most successful products. In addition, the springs we manufacture are often designed for medical devices and aerospace applications. Their smooth range and steady motion control enhance instrument articulation.   High Torque with Little Rotation: Spiral Torsion Springs Spiral torsion springs are another popular product we manufacture.These springs are ideal for applications that require high torque and less than 360 degrees of rotation. (270 degrees maximum is preferred). Spiral torsion springs are commonly used in applications that require a “return to center” function, like a medical instrument joystick. They’re also ideal for electric motors and automotive applications. If your application requires this “return to center” function, developing a custom spiral torsion spring may be the best solution. Torque with Significant Rotation: Power Springs Power springs (also referred to as clock springs) are appropriately named due to their rotational energy that takes the form of torque. The torque increases as the spring is wound tighter. They are wound around an arbor or shaft and are retained in a housing. Their large rotation capabilities make them an ideal spring for a number of automotive applications or medical devices. Power springs are also frequently used for counterbalance mechanisms in industrial sectors.

 Application of constant force spring in refrigerator door
Application of constant force spring in refrigerator door

Tid: 2022-9-14

In order to make the refrigerator operate effectively, the door should be kept closed. Keep the door open for a short time when putting or taking out food. However, opening it for a long time will affect its cooling and endanger food safety. It will also lead to excess power consumption. Fortunately, the modern refrigerator door can be added with a constant force spring to automatically close after you open the refrigerator for use. Nowadays, this kind of design is relatively rare in the market. It is generally a magnetic refrigerator door, which explains why the magnet is attached to it.   We have seen that it is essential to keep the refrigerator door closed all the time. If the door remains open for a long time, it will counteract the internal temperature balance and affect the quality of the food stored in it.When this situation continues for a long time, the compressor cannot maintain a low internal temperature. This undermines its operational efficiency. In addition, the longer the door is opened, the hotter the inside of the refrigerator will become.   Because it is very important to keep the door closed, a constant force spring is added to the refrigerator door. If you open them, they will close automatically.A constant force spring is added, which pulls the door back and seals it tightly to the frame when the door is opened. Constant force springs are often the best spring type for this application and can be manipulated in a number of ways to ensure your design works. Constant force springs are characterized by a...
