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

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.

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 of carbon brush spring in wind turbine slip ring brush holder

Tid: 2022-9-14

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...

How to determine the length of a constant force spring

Tid: 2022-9-14

  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 makes a coil spring a spring is its proportional restoring force. It's named after the 17th-century British physicist Robert Hooke who made the discovery, according to Hooke's Law. Essentially, this law describes a linear relationship where the amount of stress applied to a spring is proportional to the force applied to it.     Determine the length of the constant force spring Constant force springs differ from traditional helical wound springs. First, they are made from high-volume, thin pre-stretched stainless steel strips that are coiled into flat spirals. In contrast, coil springs are not flat, thin steel strips, but are...

As we all know, take-up spring can help take-up. It is used in many electrical products, and hair dryer is no exception. However, all such household appliances have a common feature, that is, they need a wire group to connect the power supply. However, this power line will bring some trouble to our sorting. The function of winding up lies in this. It can bring a free shrinkage process to the electrical wire group and make its winding up easy and practical. In fact, although the process of electrical wiring is not a high-end principle, it is better than cleverness. Its working principle is not complicated. It uses the spring box to limit the outer diameter, so that the center of the spring is connected with the power shaft. When the line is pulled out, it can make the shaft and the spring rotate relatively, and the spring will roll on the power shaft and store the corresponding kinetic energy. When the external force disappears, the spring will generate torque to drive the power shaft, so that the line can be retracted back into the box. In the take-up function of the reel, the effect of the power spring can not be underestimated. It can often help the required goods to take up the line quickly and simply, and become an auxiliary software favored by people. It is also due to the spring to store kinetic energy. It uses the characteristics made by the spring bearing force, and effectively uses its mechanical energy storage and driving force output, so that...

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.
