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.
Fireplaces are freestanding or wall-mounted indoor heating devices, powered by combustible materials, with internal chimneys, originating from Western homes or palace heating facilities. Because its fuel is a renewable resource, modernized and improved, it is still commonly used in the West, and is especially popular among the higher education class, which advocates environmental protection. Fireplaces can also be installed in...
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...
There are many mechanical components to choose from for your device or application. If your device requires a spring, consider constant force springs. These are a type of extension spring. They do not obey Hooke’s law, so their force remains constant, even when deflected. Because of their flat force curve, constant force springs are suitable for applications that require a...
Minimally invasive medical technology is used to reduce the number of foreign tissues that may be damaged during diagnosis or surgery, so as to reduce the recovery time, discomfort and adverse side effects of patients. The surgeon can operate the controller on the console to indirectly operate the instrument connected to the remotely operated actuator. The instrument can be disassembled...
Clockwork toys are not new to children, and children are also very interested in clockwork toys, because clockwork toys will walk around, or go straight or circle, which is very funny. This kind of toy design has lasted for decades. There are many kinds of clockwork toys, mainly cars and animals. They are suitable for children aged 3 to 12....
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...
