Application products of variable force spring

   Variable force springs and variable torsion springs can expand negative gradients and positive gradients to form a single spring. It breaks through the influence of the traditional spring affected by Hooke's law, so that the stroke and force are no longer proportionally increased, but accompanied by various elastic force-displacement combinations, such as negative slope. Therefore, a stepped constant force can be...

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...

Design of constant force springs

 A constant force spring is a spring that exerts a constant force over its range of motion. That is, it does not obey Hooke's law. Typically, a constant force spring is constructed as a coiled band of spring steel so that the spring relaxes when fully coiled. When it is unrolled, the restoring force comes mainly from the portion of...

Herkömmliche Triebfedern und vorgespannte Federn

   Herkömmliche Triebfedern und vorgespannte Triebfedern werden aus Federstahlstäben hergestellt, um ein Drehmoment bereitzustellen. Federstahl ist ein niedrig legierter Stahl mit mittlerem oder hohem Kohlenstoffgehalt und einer sehr hohen Streckgrenze. Gegenstände aus Federstahl können trotz starker Biegung oder Verwindung wieder in ihre ursprüngliche Form zurückkehren. Triebfedern verwenden flache (unbelastete) Stahlwicklungen, während ...

Vorteile der kabellosen Federkomponenten von Qianye

Alle Gardinenschnüre, ob seitlich verlegt, in Gardinen eingeklemmt oder auf der Rückseite verlegt, können für Kinder gefährlich sein. In Häusern, in denen Kinder leben oder zu Besuch sind, ist es am besten, alle schnurgebundenen Vorhänge durch schnurlose Vorhänge zu ersetzen, insbesondere in Kinderzimmern und Spielbereichen. Kabellose Rollos mit entweder einem Federsystem oder einem elektrischen System können...

Constant force springs applied in wall mounted accessories

As more and more people spend more and more time using computers, computer users spend more time sitting or standing at their desks or workstations in front of devices. Keeping what experts call "the best ergonomic positioning" can improve energy levels and overall comfort. For this purpose, the input and output devices must be placed in appropriate positions. The proper position can...

Constant force spring is used in removing an implanted object using laser cut hypotubes

Removal or extraction of the lead may be difficult. As mentioned above, the body's natural healing process forms scar tissue over and along the lead, and possibly at its tip, thereby encasing at least a portion of the lead and fastening it even more securely in the patient's body. In addition, the lead and/or tissue may become attached to the...
