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...

Le processus de production personnalisé du ressort ne peut pas être réalisé à volonté

Comme nous le savons tous, bien que le ressort ne soit qu'un petit accessoire élastique, il joue un rôle important dans la vie et la qualité du ressort a un grand impact. La plupart des ressorts sont des produits personnalisés, de sorte que le processus de production personnalisée ne peut pas être négligent. Lors de l'achat d'un ressort, les clients doivent généralement d'abord concevoir les données du produit et communiquer...

Constant Force Springs

The extension type of Constant Force Spring represents the most basic, yet most versatile, type of constant force spring. It is a pre-stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. When the strip is extended (deflected) the inherent stress resists the loading force, the same as a common extension spring,...

Traditional power springs and preloaded springs

   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...

Application of springs in industrial doors

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....

Constant Torque Spring Motor

A constant torque spring motor is a strip of prestressed spring material that forms a coil and is stored on a small storage drum. The free end is then pinned and rewound onto the larger output drum; this is the "winding" part of the constant torque spring cycle. When the output drum is released, the spring will return to the...
