What are constant force springs and how are they used?
Constant force springs are specialized springs that are used to provide a constant force over a range of motion. This makes them ideal for use in a variety of applications, such as automotive or robotic systems.under we will take a closer look at what constant force springs are and how they can be used. What are constant force springs? A constant force spring is a type of spring that produces a constant force over its entire range of deflection. This type of spring is often used in applications where a stable force is required, such as in the actuation of a valve. Constant force springs don’t have much in common, either in form or function, with standard helically wound springs. For starters, constant force springs are formed from pre-tensioned metal strips, rather than wire. At their most basic level, however, constant force springs do exactly what other springs do. That is, they conform to Hooke’s Law. Hooke’s Law essentially states...

Spring has been very common in people's daily production and life, ranging from planes, trains and cars to household appliances and daily necessities, and even children's stationery for school. It can be seen how important spring is to our life.     What is the definition of spring? It is a mechanical part that uses elasticity to work. Generally made of spring steel. It is used to control the movement of mechanical parts, mitigate impact or vibration, store and measure the size of force. It is widely used in machines and instruments.     For a professional spring manufacturer, the most basic production goal is to infinitely pursue the high quality of products. Therefore, in order to improve the performance of the spring, it is often assisted by pre heat treatment, that is, the process of strengthening the quality of spring steel is used to further strengthen the spring.     In fact, the so-called pre heat treatment is what we often...

Design steps of constant torque spring
Design steps of constant torque spring
Constant torque spring is a constant force spring with special force moving between two spools. The spring is stored on the storage spool and wound reversely on the output spool. When released, torque is obtained from the output spool when the spring returns to its natural curvature on the storage spool. The spring does not need to be connected to the storage spool. The spring can be installed in a cavity without storing the spool at all. However, friction will then be introduced and torque requirements will change. The torque generated by the constant torque spring will increase slightly after several revolutions. Constant torque, even negative torque, is also possible. Negative gradients of up to 50% can be achieved in some applications. As for the design of constant torque spring, when considering the use of constant torque spring, it is strongly recommended that you talk with Qianye engineers and study various design parameters. Some initial design calculations can be carried out...
[Qianye precision]Physical design and recoil force of constant force spring
[Qianye precision]Physical design and recoil force of constant force spring
 In most types of springs, when the spring is compressed and then relaxed, the force applied is proportional to the distance the spring is stretched. Unlike ordinary springs, constant force springs do not comply with this rule. Due to the physical design of constant force spring, its return force remains constant. Therefore, constant force springs are useful in many applications that require consistent recoil.     The behavior of ordinary springs can be described by a mathematical equation called Hooke's law. The law points out that the force of the recoil spring in the recoil direction is equal to the distance between the spring displacement and the equilibrium point. In other words, it is how much the spring is elongated and multiplied by the mathematical constant, that is, the spring stiffness. The spring recoils in the direction opposite to the stretching direction. Because many elastic materials work in this way, Hooke's law has a wide range of applications in the field of physics.  ...

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...

Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while pre-stressed power springs use pre-stressed steel to produce a larger range of usable torque than conventional power springs.          During the manufacturing process, the spring is wound into the retaining ring or the customer's housing (the retaining ring is pictured below). When ready for final installation, carefully install the spring into its housing with the outer end attached to the outer edge and the inner end attached to the mandrel (see photo below). During operation, the housing or mandrel will be fixed while the other component is free to rotate. Depending on the requirements of your specific design, it may be beneficial to use a fixed mandrel/free box or free box/fixed mandrel arrangement.        These springs are typically used to retract the cord or cable of the spool. You might see it in lawn mowers, retractable lanyards, or dog leashes. This is also the type of spring used to drive many mechanical clocks and timers, which is why they are sometimes called "clock springs". The load provided by the spring increases with the cross-sectional area of ​​the material. The number of turns the spring can provide depends on the space available between the mandrel and the...

 Small engines are well known and are commonly used in lawn mowers and garden tractors and various other garden and lawn maintenance tools, in addition to other environments. Typically, each of these engines is equipped with a recoil starting system that includes a rope that rotates the starting mechanism to engage a flywheel that is connected to the engine for starting purposes. Once the rope starter is pulled, the recoil mechanism is always provided with the engine to reel the starter rope back to the starting mechanism.   The recoil portion of the starter mechanism is operated by a power spring that tensions when the operator pulls on the starter rope. Once the rope is fully pulled, the operator releases it. Most power springs on the market often fail, so the recoil rewinding mechanism needs to be disassembled and the spring replaced. And replacing the spring is a tedious task because the operator needs to keep the spring in the cavity inside the recoil starter pulley and then coil the spring into the pulley mechanism while keeping the spring in the coiled position and under sufficient tension. Such a procedure requires not only skill, but sometimes infinite patience. That's why the quality of the power spring is a top priority - after all, no one wants to change the power spring inside too often.   Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 20 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable...
