Power spring

Feature:
The power spring is coiled from steel strip. A spring box is required to limit its outer diameter. The center of the spring is connected to the shaft. When an external force is applied to make the shaft and the spring rotate relative to each other, the spring will be wound on the shaft and stored Torsion, when the external force disappears; the spring generates torsion on the shaft or spring box.


Advantage:
Power springs are divided into natural power springs and pre-stressed power springs according to their relaxed shape. In contrast, the Pre-stressed power spring can store 25% to 55% more torque and provide more effective turns.




 
Application
The main applications of power springs include clockwork toys, timers, and automatic rewinding devices (such as power cords, hose reels, car seat belts)

 
The high-precision pen-type syringe uses a unique power spring to provide small and highly accurate drug dosages.
Power springs can be used in clockwork toys, timers, and automatic rewinding devices, such as power cords, dog leashes, hose reels, and automatic retraction devices for car seat belts.

Notice:
Because this type of spring is a non-standard product, the same shape has different sizes. QianYe has specialized in research and development and production of constant force springs for 20 years, and can customize constant force springs with a thickness of 0.075mm-0.85mm and a width of 4mm-50mm.You can also provide drawings or data (the thickness of the spring, width, working length, inner diameter, outer diameter), and the customer service staff can provide you with a quotation and customized cycle. Welcome to consult.
