Factoren die het breken van krachtveren beïnvloeden: The power spring is made of stainless steel strip. A spring box is required to limit its outer diameter. The spring center is connected with the shaft. When an external force is applied to make the shaft rotate relative to the spring, the spring will roll on the shaft center and store the torque. When the external force disappears, the spring will produce the torque on the shaft or spring box. The advantage of power spring is that it can be divided into natural power spring and pre force power spring according to its relaxed shape. In contrast, the preloaded power spring can store 25% to 55% more torque and provide more effective turns. Power springs are mainly used in products such as clockwork toys, timers and automatic rewinding devices (such as power cord, dog puller, pipe winder and automobile safety belt) It is often seen that the scroll spring purchased will break soon after it...

Power spring used in automobile safety belt: Safety belt is equal to life belt. Everyone should see the painful accidents caused by not wearing safety belt. I believe everyone is familiar with the car safety belt. It is a safety device to avoid rushing out of the car during collision and causing death and injury. Automobile safety belt is recognized as the cheapest and most effective safety device, and it is also a necessary safety configuration. In a typical safety belt system, the safety belt is connected with a retractor. The core component of the retractor is the reel, which is connected with one end of the safety belt. Inside the retractor, with the help of the action of the power spring, the webbing can expand and contract freely with the movement of the user's body without loosening the webbing. In case of emergency braking, collision or sharp change of vehicle driving state, the sensitive element in the retractor will lock the reel to fix the webbing at a certain position and bear the load imposed on the webbing by the user's body. The power spring is made of rolled steel strip. A spring box is required to limit its outer diameter in use. The center of the spring is connected with the shaft. When an external force is applied to make the shaft rotate relative to the spring, the spring will roll on the shaft center and store torque.

Do you know function of the spring in fire damper?: What do you think when you see the fire damper? I believe many people will think of "fire". In fact, the word "fire" must be familiar to everyone! What do you think of when you hear this word? People trapped by the raging fire? Or the scene of our brave firefighter uncle fighting the fire? The following are the fire events in recent days. At 14:00 on March 12, 2022, a fire broke out in the oil fume pipeline of a hotel in Huazhou City. At 3:46 on March 8, 2022, a fire broke out at the construction site of Jinke Xiangsheng Yueyuan at the intersection of chegang road and Xiyun road in Zhenjiang new area. In the early morning of March 14, 2022, a fire broke out in Kundulun District of Baotou City, which has killed 7 people so far. Do you feel very sad at this time? Uncontrolled fire is always a serious risk. In an emergency situation a fire can spread via a ventilation ductwork. Therefore it is essential that the ventilation ductwork is equipped with high-quality and robust fire dampers that also prevent smoke from spreading and therefore enable safety for escape routes. But what is a fire damper? Fire Dampers are used in air transfer openings, ducts and other places where fire rated structures (e.g. walls, floors or other fire barriers) are penetrated. If these openings wouldn’t be protected, the fire would easily spread to other spaces and damage the property and pose a danger to people working/being in this environment. The idea...

Advantages of Qianye carbon brush spring in motor: There are many kinds of carbon brush springs. Wired carbon brush springs also have steel belt carbon brush springs. The linear type is mainly compression spring and torsion spring. These springs are traditional springs. At present, the more famous motor manufacturers or electrical appliance manufacturers have begun to use steel belt carbon brush coil spring in the motor. The traditional compression spring and torsion spring are relatively backward and are generally used in low-cost carbon brush devices. The only advantage is that the price is cheap, which is several times lower than that of steel strip spring. However, the use of traditional spring in medium and high-end motors greatly reduces the product quality and competitiveness. Compared with the motor using traditional spring, the coil spring motor is completely two different concepts and quality, and the sound produced by the operation of the two motors is also different, making the service life even more incomparable. The use of carbon brush spring greatly improves the service life and stability of the motor. The traditional type of spring is not only noisy but also environmentally friendly. However, there are few domestic manufacturers that can really do a good job in carbon brush spring. Carbon brush spring needs a long time of production experience to produce high-quality carbon brush spring. Shenzhen Qianye Precision Metal Co., Ltd. has more than ten years of product R & D, production and manufacturing experience, and various application designs and solutions of spring. The advantages of carbon brush spring produced by Qianye in motor application are as follows: 1 Shorten the outer diameter of the motor...

Veermotor met constant koppel: 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 storage drum to assume its natural curvature, rotating the output drum and providing an almost constant torque. Constant torque springs are made of type 301 high quality stainless steel and are supplied in coil form for mounting on the motor drum. Its main features are: 1. Long time deflection under almost constant torque. Positive or limited negative gradients can be achieved. 2. Minimal inter-coil friction and resulting hysteresis, which is common in power springs. 3. Rotary motion is provided directly from the output drum or linear displacement by using cables and spools. Many applications utilize constant torque spring motors, such as: cord retractors, balance retrieval and return applications, drive motors, cordless curtains, and more. The spring features a high turn design, making it ideal for balancing applications. When they are fully turned, the springs apply a constant torque. You can also guarantee high torque levels. This is due to their compactness and high efficiency. The function of the constant torque spring motor depends on the design. The size of the spring can vary. Therefore, they make them suitable for use in a variety of applications. We strongly recommend that you consult...

Design of Constant Force Spring in Spool Damper: When powered by a damped constant force spring mounted on the spool, there are several key principles that influence the design of linear motion applications. These principles support robust and consistent performance of products in a variety of applications, including automotive and aircraft interiors, industrial machine components, and many other user interface applications. The example components shown above will be cited as examples of the various design principles detailed below. This example assembly has a sliding drawer (shown in red) powered by a constant force spring mounted on a spool (spool in green; constant force spring shown in yellow) running within a mounting base (shown in grey), such as a central Console a car. A ratchet or door latch mechanism (not shown) can be implemented to allow the tray to be locked in place with a single press by the user. This example is a typical set of applications used in the automotive industry. 1. Preload spring When a constant force spring is in its free state, it does not exert any force. As the spring stretches, the spring force rapidly increases from zero to nominal load. However, to avoid including this "accelerated" part of the work envelope, the design can use preloading. An example of preloading is shown in the figure below. Note that although the mechanism is retracted, the depicted spring is extended. To include preload in the design, ensure that the spring extends a distance equal to the outer diameter of the coil during assembly in order to engage...
