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.

Product Description

The power spring is made from flat-shaped material(It is usually flattened by steel wire or made from high-carbon steel strip and high- strength stainless steel strip) and has a spiral appearance. Typically, the outer end of the spring is fixed to the wheel hub, while the inner hook can engage with the arbor. By rotating the arbor or the wheel hub, the power spring winds and unwinds to generate torque. 

Product Description

A power spring (Prestressed), when installed on a product, appears similar in appearance to a traditional power spring. However, because it is wound in the opposite direction, it takes on an "S" shape when released it. Compared to traditional power springs, power springs(Prestreessed) can provide a more streamlined force output and offer more working turns and greater force within a limited space. 

Product Description

In carbon brush applications, constant force springs not only help reduce noise, sparking, and electromagnetic interference, but also ensure consistent pressure on the commutator regardless of brush length. These springs can also be custom-designed and manufactured according to customer requirements for better adaptability.

By leveraging these combined advantages, the use of constant force springs not only enhances product quality but also helps establish a competitive edge in the market. They are especially effective in improving performance for devices that require long-term stable operation, such as industrial motors, power tools, and electric vehicles.

Product Description

A constant torque spring is typically mounted on a storage shaft.Its outer end is connected in the reverse direction to the output shaft.When the output shaft is rotated, the spring is wound in reverse, generating a constant torque on the output shaft. When the external force is removed, the spring rewinds from the output spool back onto the storage spool, returning to its natural state.

Product Description

Compared to constant force springs, variable force springs have a pulling force that changes with the spring's extension. The pulling force is typically low at the beginning and increases progressively as the stroke becomes longer.
