How to determine the length of a constant force spring

  Constant force springs are mechanical devices used in applications that typically require some kind of balance or retraction mechanism. In design and function, constant force springs differ from the more common types of coil springs. They apply a consistent linear force or torque that remains constant over a wide range of motion. When a coil spring is under force, whether it...

Physical principle behind constant force spring

When you walk into your office building on your way to work every day, or into your local bank, or any commercial facility, you may open a heavy glass door. When you cross the threshold, the door closes behind you, and you don't think about it. However, the heavy glass door was probably closed by a constant force spring. Constant force springs are...

The customized production process of spring cannot be carried out at will

As we all know, although the spring is only a small elastic accessory, it plays an important role in life, and the quality of the spring has a great impact. Most springs are customized products, so the process of customized production cannot be careless. When purchasing a spring, customers usually need to design the data of the product first, and communicate...

Constant Force fjedre

Forlængertypen af Constant Force Spring repræsenterer den mest grundlæggende, men alligevel mest alsidige, type konstant kraftfjeder. Det er en forspændt flad strimmel af fjedermateriale, som er formet til stort set konstant radius-spoler omkring sig selv eller på en tromle. Når båndet forlænges (afbøjes), modstår den iboende spænding belastningskraften, det samme som en almindelig forlængerfjeder,...

Traditionelle kraftfjedre og forspændte fjedre

   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...

Anvendelse af fjedre i industriporte

The constant force spring of the industrial door mainly plays a balancing role and reduces the burden on the motor. The force of the spring is equivalent to the force of the industrial door, which is the most ideal configuration state. If the spring force is too large or too small, it will affect the operation of the industrial door....

Fjedermotor med konstant moment

En fjedermotor med konstant moment er en strimmel af forspændt fjedermateriale, der danner en spole og opbevares på en lille lagertromle. Den frie ende fastgøres derefter og spoles tilbage på den større udgangstromle; dette er den "viklede" del af fjedercyklussen med konstant drejningsmoment. Når udgangstromlen slippes, vender fjederen tilbage til...
