1. The power spring is a coil spring, which is made of stainless steel band. Power springs store and release rotational energy in the form of torque through a central mandrel or spring housing.
2. The power spring has a power rotation torque in a limited space when working, and is usually used for cable reels, dog leashes, medical equipment, etc.
3. Power springs are also called clock springs, coil springs, and helical torsion springs.
4.Power springs are divided into conventional power springs and prestressed power springs. Pre-stressed power springs Compared to traditional power springs, pre-stressed power springs increase the recoil process and can provide 25-55% greater output than traditional power springs.
What are the advantages of a power spring?
1. High torque transmission per unit deflection.
2. Normal residual stress.
3. The prestressed power spring can store 25%~55% more energy than the traditional spring.
What products can power springs be used for?
There are many types of power springs used in auto parts, and one of the most common parts is seat belts. Seat belt essential features such as long range, long life, easy access and automatic retraction, pre-stressed power springs are the best choice for it.
Dog leashes, hose reels, badge reels, and some toys (hairsprings) also use power springs to retract easily. It has the characteristics of long length, long life cycle and convenient retraction.
Power springs are also widely used in medical equipment and healthcare applications such as auto-injectors, cable and wire management. and many more.
