Design a molla a spirale

Come determinare la lunghezza di una molla a forza costante

  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...

Principio fisico alla base della molla a forza costante

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 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...

Applicazione di molle nei portoni industriali

La molla a forza costante del portone industriale svolge principalmente un ruolo di bilanciamento e riduce il carico sul motore. La forza della molla è equivalente alla forza del portone industriale, che è lo stato di configurazione più ideale. Se la forza della molla è troppo grande o troppo piccola, influenzerà il funzionamento del portone industriale....

Motore a molla a coppia costante

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...
