Protector de resorte de cepillo: Conventional motor arrangements include a rotor with windings to conduct current during machine operation. As the rotor rotates, current is conducted through the rotating elements from sources external to the rotor to the rotor windings. A rotating element such as a slip ring or a commutator contacts the brush spring to conduct current. There are two main types of brush springs, single-coil brushes and double-coil brushes. The brush springs provide constant pressure to the commutator and slip rings while minimizing brush wear, burning and scratching. They provide excellent work at high speeds for improved motor performance. The brush spring is relative to the rotating element, and the brush spring is ground due to friction during use. It is damaged and needs to be replaced periodically. So sometimes the brushes are replaced during motor downtime. To change the brushes safely, the operator uses one hand (to avoid current passing through the operator's body). Brush carriers...

When the exciter commutates, the contact between the carbon brush and the commutator is not good, and the contact resistance is too large ; the uneven thickness of the oxide film of the rectifier or slip ring causes the unbalanced distribution of carbon brush current ; or sudden change of load and sudden short circuit lead to abnormal voltage distribution between commutators ; unit overload and imbalance ; carbon brush selection is unreasonable, carbon brush spacing...

Design steps of constant torque spring: Constant torque spring is a constant force spring with special force moving between two spools. The spring is stored on the storage spool and wound reversely on the output spool. When released, torque is obtained from the output spool when the spring returns to its natural curvature on the storage spool. The spring does not need to be connected to the storage spool. The spring can be installed in a cavity without storing the spool at all. However, friction will then be introduced and torque requirements will change. The torque generated by the constant torque spring will increase slightly after several revolutions. Constant torque, even negative torque, is also possible. Negative gradients of up to 50% can be achieved in some applications. As for the design of constant torque spring, when considering the use of constant torque spring, it is strongly recommended that you talk with Qianye engineers and study various design parameters. Some initial design calculations can be carried out...

[Precisión de Qianye] Diseño físico y fuerza de retroceso del resorte de fuerza constante: In most types of springs, when the spring is compressed and then relaxed, the force applied is proportional to the distance the spring is stretched. Unlike ordinary springs, constant force springs do not comply with this rule. Due to the physical design of constant force spring, its return force remains constant. Therefore, constant force springs are useful in many applications that require consistent recoil. The behavior of ordinary springs can be described by a mathematical equation called Hooke's law. The law points out that the force of the recoil spring in the recoil direction is equal to the distance between the spring displacement and the equilibrium point. In other words, it is how much the spring is elongated and multiplied by the mathematical constant, that is, the spring stiffness. The spring recoils in the direction opposite to the stretching direction. Because many elastic materials work in this way, Hooke's law has a wide range of applications in the field of physics. ...

Application of variable force spring in time-delayed shelf: Supermarkets and convenience stores can be seen everywhere. Now more and more people are developing retail. Traditionally, products on shelves are usually placed in order. Some merchants install automatic propellers. After customers buy products, the propellers will push The products at the back are automatically advanced, and when the customer wants to find this product, it is easier to see, which is convenient for the customer to find the desired product and stimulates the customer's desire to buy. Theft of small items in retail stores is a problem that occurs. An ideal form of anti-theft is to create time delays between the dispensing of multiple products. If there is a considerable delay between the distribution of individual products, thieves are less likely to steal the products. A shelf-delayed pusher equipped with variable force springs can eliminate this problem. The propulsion system includes a pusher, a track and a stop mechanism. The propulsion system includes a resistance mechanism connected to the track and the pusher, and controls the forward movement of the pusher along the track, thereby controlling the speed at which the product is propelled for retrieval by the consumer. When engaged, the stop mechanism prevents the pusher from advancing the product, and the indexing mechanism also limits the forward travel of the pusher to a discrete distance. The variable force spring can expand the negative gradient and the positive gradient into a spring. It breaks through the influence of the traditional spring affected by Hooke's law, so that the stroke and force are...

Application of constant force spring in lifting window: The lifting window is different from the traditional internal opening, external opening and ordinary push-pull mode, but adopts the opening mode of lifting up and down. Because it is mainly popular in North America, it is also called American lifting window. It is one of the two major door and window categories in the world. The lifting window is more compact than the left and right lifting windows, which is determined by the structure of the window. The traditional lifting window is a sash frame structure, that is, when the window sash is opened left and right, it is realized by sliding the lower pulley on the sliding rail of the window frame. However, there is a gap between the pulley and the slide rail, and the smoothness of the opening must be taken into account, which will inevitably lead to the decline of the sealing performance. The lifting window is a frame-encased sash structure. The sash is wrapped in the window frame and runs vertically up and down. Through the multiple seals of high-quality siliconized tops, the sash frame is tightly fitted around it, and the sealing performance is significantly better than that of the left and right lifting windows, second only to Fixed and casement windows. The advantages of the sliding doors and windows are: 1. The characteristics of large ventilation, the lifting windows can be opened by 2/1, and the air entering the room can be convected. The European-style lifting windows and casement windows basically cannot open more than half of the area. Second, there can be different...

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...

Diseño y función de Twin Spring o Motor Brush Spring: One of the most unique spring designs is called a twin spring. Its name is derived from the characteristic of having two springs formed from the same strip of stainless steel material. These custom springs are intended to work together, in unison, doubling the force of a single spring. Twin springs are a version of a constant force spring, providing constant force throughout the travel length. The area between the two coils is referred to as the saddle area, which is formed to fit over the part or component that is being pushed. The saddle can also be cut-out to provide access to the component and is best designed when assigned a dimension to fit over that specific part. It can be located at different heights between the coils for ease of assembly or as an indicator for direction. Twin springs are used in a wide range of applications where available space is limited and a relatively strong force is required. Medical devices and surgical mechanisms incorporate this design to push or feed surgical staples in disposable skin staplers. Electric motors utilize the twin spring to provide a constant force on the carbon brush, extending the life of the motor and increasing reliability and overall quality. These springs are also referred to as motor brush springs. Advantages of twin spring: 1. Under the same elasticity, the double winding spring saves volume. 2. Because the shape is symmetrical, the output is more stable. 3. Increase the length of available carbon brushes. ...

How long can the spring last?: How long can stainless steel springs last? This is a common problem. You might think that as long as it's not stretched beyond the point of recovery, the spring will always return to its original shape. A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel, the types of springs are complex and diverse. However, spring life depends on many factors. 1. Spring design Are they properly designed for their intended purpose? Many are not, errors in spring design are the main cause of premature spring failure. When choosing a spring, remember to pay attention to what it is for and how it will be used. Is spring strength more important or elasticity? If you're not sure, experts can help guide your decision. 2. Quality of manufacturing materials The life of the spring is also related to the quality and modulus of elasticity of the materials used in its manufacture. Make sure your springs are made of the best quality material for the desired application. For example, stainless steel springs have high strength, low stress relaxation, corrosion resistance and heat resistance. However, their performance decreases at sub-zero temperatures. 3. Application pressure and environmental conditions If the force applied is greater than the spring is designed to withstand, fracture may occur....

Qianye innovative power spring plays an important role in Hose Reel: Hose Reel is also called pipe winder, Winder, reel, drum and air drum. Among many working equipment, the pipe winder is a very labor-saving and convenient long-distance energy transmission device. Its basic structure consists of hose, power spring, rotating shaft and other safety mechanisms. The power spring of the hose reel can stretch and shrink the pipeline, intensively manage various energy pipelines, and change the previous phenomenon that the pipeline, power plug, oxyacetylene pipeline, bulb, spray gun and other tools are scattered in disorder. It can be used alone or in combination, which greatly saves the factory space, beautifies the working environment and improves the grade of the enterprise. Improve the working environment. 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. When the external force disappears, the spring will produce torque on the shaft or spring box. The tension on the spring has been pre loaded at the factory, and the spring produced by an improperly selected manufacturer may become unstressed or have excessive tension. Too much tension will lead to too fast and fierce retraction. At the same time, the service life will be relatively short, and the elasticity will soon fail. Our company has made technical product updates for power springs. First of all, our company adopts 301 stainless steel with...

Constant force spring damper: Dampers are widely used in building structures to dissipate energy and reduce vibration. However, the traditional damper has complex structure, poor durability and corrosion resistance, and low working stability. After using for a period of time, the damper is prone to aging and deformation can not be restored, so it can not be used anymore. Most of the existing dampers use shape memory alloy (SMA), which is a material composed of more than two kinds of metal elements through thermoelasticity, martensitic transformation and its inversion; Using shape memory alloy, the damper can automatically restore to its original shape after deformation, which is used for the restoration of building structures after deformation. However, the existing dampers only use the performance of shape memory alloy (SMA) wire itself, and the cost is expensive, which is not conducive to the large-scale use of dampers. The design of constant force spring can be added to the self resetting damper. The damper includes piston parts, U-shaped plates and moving rods. The constant force spring is set between the tension moving rod and the pressure moving rod. The constant force spring tightens the tension moving rod and the pressure moving rod to be close to each other, so that the tension moving rod and the pressure moving rod respectively lean against the end close to each other in the corresponding sliding hole. It is conducive to the large-scale use of self resetting dampers. Constant force spring is a kind of functional material with high ductility, which has the advantages of constant load, high energy storage density, low friction loss and so on....
