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...

We have been a natural partner for designers and manufacturers of electric vehicle charging stations, providing them with trouble-free cable management solutions for their electric vehicle charging stations around the world. By applying our power springs in retractable cable reels, cable wear is reduced and cables can be neatly stored away when not in use. The natural tendency of the power spring to expand imparts torque to the mandrel or case, which generates the available torque. The torque generated is cumulative, so the torque increases as the spring preloads and decreases as the spring unwinds. Torque and a total number...

The seat belt's principle is that when it is fastened, it can be stretched at will. When braking in a hurry, however, the belt is tightened, and the belt reel is the key component that plays this role. Its function is to store the webbing and lock it out, making it the most complex mechanical part of the seat belt. The part of the reel that allows the seat belt to be reeled in freely is the power spring. The spring is coiled from steel tape and is used with a spring box to limit its outer diameter. The centre...

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...

How do I find the right constant force spring for my cable accessories? How to determine the constant force spring's constant spring force, magnetic properties, corrosion resistance, etc. is the first consideration for cable accessory manufacturers and customers. Constant force springs are used in the same environment as cable accessories and are generally wrapped externally with some strip material to prevent axial displacement along the cable. In use, wrapped around the entire joint or inside the terminal, there is no direct contact with moisture, but it is easy to contact moisture when the sheath is broken, plus the heat generated...

Springs are mechanical components that are widely used in engineering applications. They are used to store and release energy, control motion, and absorb shock and vibration. A spring is a device that can be deformed by an external force and returns to its original shape when the force is removed. There are many types of springs, including coil springs, leaf springs, torsion springs, and constant force springs. In this article, we will focus on the constant force linear spring and its physics and applications. What is a Constant Force Linear Spring? A constant force linear spring is a type of...

Constant force springs are a type of mechanical spring that provides a consistent force throughout their range of motion. They are designed to exert a nearly constant force over a wide range of deflections. The reason they are called constant force springs is that they provide a uniform force or tension over the entire length of their extension. These springs are made from flat strip materials that are rolled into a helical shape. The spring is then coiled tightly into a spool, which gives it its unique ability to provide a constant force. These springs are commonly used in a...

Constant Force Springs, also known as clock springs or spiral springs, are a type of mechanical spring that provides a constant force throughout its range of motion. They are widely used in various applications, including automotive, aerospace, medical, and industrial equipment. In this article, we will explore the benefits of constant force springs and how they can be utilized performance and efficiency. Advantages of Constant Force Springs One of the main advantages of constant force springs is their ability to maintain a consistent force over a wide range of deflections. This makes them ideal for applications where a constant and...

Linear springs have been used for centuries to store and release mechanical energy, and they remain an essential component in countless applications today. Linear springs use the principle of Hooke's Law to produce a force proportional to their deformation, making them invaluable in situations where force must be applied over a precise distance or with a specific amount of tension. Constant force linear springs are a specialized type of linear spring that offer unique benefits for applications requiring high precision. What is a Constant Force Linear Spring? A constant force linear spring is a spring that provides a consistent amount...
