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. ...

Quanto può durare la primavera?: 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....

Application of constant torque spring in 3D printer: 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...

The power source of clockwork toy — constant torque spring: Clockwork toys are not new to children, and children are also very interested in clockwork toys, because clockwork toys will walk around, or go straight or circle, which is very funny. This kind of toy design has lasted for decades. There are many kinds of clockwork toys, mainly cars and animals. They are suitable for children aged 3 to 12. Clockwork toy is the general name of motor toys with clockwork as power device. Spring is a kind of spring machine. In the spring, there is a recyclable coil spring. The principle is similar to that of a gyroscope. When the spring rotates, the coil spring inside is wrapped tightly. In short, it is to accumulate power potential energy, and then the spring returns, which naturally produces power potential energy. The clockwork toy uses a constant torque spring, which is made of stainless steel. The external force reverses the spring from the natural shape to the output wheel (energy storage). When the external force is removed, the spring will return to the natural state and generate constant torque on the output wheel, so it is called constant torque spring. Compared with the power spring, the constant torque spring has the advantage that the torque will not change due to the increase of the number of turns, and there is no limit on the number of turns available. The constant torque spring is mostly used in the design of multiple turns. The number of invalid turns is less, more energy can be stored and the efficiency is higher. When the spring is...

How long can constant force spring be used ?: Constant force spring, also known as hair spring, is made of stainless steel strip. The force added to the spring determines the diameter, force and life of the spring. The action of constant force spring is similar to that of stretching ribbon. The spring stretches and rolls back, and the working part is tangent to the spring ' s own circle. As long as the diameter of the spring is certain, the force of the spring is constant. According to the application principle of constant force spring, constant force spring can be divided into linear constant force spring and rotational constant torque spring. When linear stretching force units are : kg, Newton, pounds, etc. Then how long can the constant force bar be used ? The life of the constant force bar is limited, and the life requirement of the spring should be considered when designing the constant force bar. This step is important because it affects the things behind the design ; improper consideration may lead the design to a wrong direction ; properly considered, the design will be easier to succeed. It is very important to determine the number of spring stretching before designing the constant force bar. Spring stretching times explanation : a refers to the spring in any part of a stretch and roll back process. Since the constant force spring provides force through the bending of the spring, any part used belongs to the spring body. In other words, a spring with a total design length of 25 ’ uses the length of...
