Constant Force Spring
Product Description
A constant force spring is a unique and versatile type of spring made from a strip of steel formed into an inwardly wound spiral shape. Unlike traditional springs, when you stretch a constant force spring, it generates a pulling force that remains consistent from the beginning to the end of the extension. This force does not change regardless of the extension length.
It is typically mounted on a wheel or shaft, with one end of the spring fixed and the other end connected to the product that requires pulling force. Once installed, as the product moves, the constant force spring maintains a steady pulling force throughout.
Because of its stable force output, the constant force spring is very useful in various mechanical applications, such as height-adjustable desks and chairs, the height adjustment function of electric fans, and the opening/closing mechanisms of fire doors.
In summary, a constant force spring refers to a spring that maintains the same pulling force after being extended, allowing machines to operate more smoothly and reliably.
