The importance of springs to the aerospace industry
The importance of springs to the aerospace industry
       Springs are an important part of many different industries, including the aerospace industry. They form the backbone of many components and allow planes, drones, satellites, solar panels, aircraft controls, valves, throttles, and more to function their way. Without the spring, the industry would not be the same. Strict military and aviation guidelines mean that all components of the aircraft, including the springs, must be of the highest quality and precision; they support a wide range of applications and reduce part weight while maintaining the highest performance standards. This makes springs vital to the aerospace industry. Without springs, we wouldn't be able to have the essentials of aerospace. For example, retractable tray tables, trunk doors, handrails, stairs and cup holders require springs to function. They help open and close many components that wouldn't exist without them—and, more importantly, springs are some of the main elements of aircraft landing systems. They are also present in satellite dishes and probes...

 "Constant force spring" is a necessary component for cable accessory manufacturers at home and abroad
"Constant force spring" is a necessary component for cable accessory manufacturers at home and abroad

Time:2022-9-14

With the increasing application of cold shrinkable cable accessories, constant force spring has become a necessary component for cable accessories manufacturers at home and abroad. How to find a suitable constant force spring in practical application? How to determine the continuous elasticity, magnetism and corrosion resistance of constant force spring has become the first consideration for cable accessory manufacturers and customers. Whether imported brand or domestic brand, the use of constant force spring for standard cable accessories has become a standard configuration, but the quality is uneven. Faults often occur due to factors such as material, type selection or performance. The corrosion resistance of constant force spring is related to the material and processing technology. The corrosion resistance of stainless steel mainly comes from chromium. The corrosion resistance of steel will be greatly improved only when the chromium content exceeds 12%, and the addition of nickel will also improve the corrosion resistance. Constant force spring for cable is generally made of stainless steel 301 in China and x12crni17 in foreign countries 7 stainless steel is made of high tensile strength and hardness during cold processing, non-magnetic, but magnetic after cold processing. After heat treatment, the magnetism can be eliminated, and the surface will turn light yellow, but the corresponding hardness will decrease.   The application environment of constant force spring is the same as that of cable accessories. The outside is generally wrapped with some strips to prevent axial displacement along the cable. In the process of use, it is wrapped inside the whole joint or terminal and will not be in direct contact with moisture, but it...

A constant torque spring can play such a big role in the take-up device

Time:2022-9-14

Constant torque springs can help take up the wire and are used in many products. All electrical products have a cord set that is connected to the power supply, but this power cord will bring some trouble to our arrangement. The function of the constant torque spring is this, it can bring a free shrinkage process to the electrical cord set , making it easy to take up the line, very practical. When the external force reverses the constant torque spring from the natural state to the output wheel, once the external force is removed, the constant torque spring will be rolled back to the natural state, and a constant torque will be generated in the output wheel at the same time. Constant torque spring can be used in automatic winding, balance weight and power source, such as automatic winding device of power line. Advantages of constant torque spring over power spring: 1. The torque will not change as the number of turns increases. 2. There is no limit on the number of available turns, and the design of multiple turns mostly adopts constant torque spring.  3. The number of invalid turns is less, more energy can be stored and the efficiency is higher.

 Motor brush spring and wind turbine maintenance
Motor brush spring and wind turbine maintenance

Time: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...

The service life of the dog walker can be extended to 30000 to 100000 times. When this power spring is applied to the dog walker, the quality of the dog walker has been greatly improved. When walking the dog, we need to pay attention to bring the dog's little partner - the dog walker, and then the obedient dog should also bring the dog walker. Don't expect the bridge section of the dog looking for the master in the movie to happen. Before using this kind of traction rope, I always used a fixed 1.5m long rope. Usually I use the traction rope to prevent dogs from running around and attacking pedestrians. But there was once a time when walking a dog. Now many shared bicycles and electric vehicles often shuttle back and forth at a fast speed when walking around the corner. An electric motorcycle brushed past the dog. Fortunately, after the rope was shortened, it was able to effectively protect the dog and prevent accidents. However, many friends would say that it would be good to buy a shorter rope? But in fact, many times we need to give dogs enough range of activities, so this time can reflect...
 How long can the spring last?
How long can the spring last?

Time:2022-9-14

How long can stainless steel springs last? This is a common problem. You might think that as long as it's not stretched beyond the point of recovery, the spring will always return to its original shape. A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel, the types of springs are complex and diverse. However, spring life depends on many factors.         1. Spring design Are they properly designed for their intended purpose? Many are not, errors in spring design are the main cause of premature spring failure. When choosing a spring, remember to pay attention to what it is for and how it will be used. Is spring strength more important or elasticity? If you're not sure, experts can help guide your decision.       2. Quality of manufacturing materials       The life of the spring is also related to the quality and modulus of elasticity of the materials used in its manufacture. Make sure your springs are made of the best quality material for the desired application. For example, stainless steel springs have high strength, low stress relaxation, corrosion resistance and heat resistance. However, their performance decreases at sub-zero temperatures.       3. Application pressure and environmental conditions       If the force applied is greater than the spring is designed to withstand, fracture may occur....
