Протектор на пружината на четката: 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...

Анализ на причините за повреда на въглеродните четки на генераторния комплект: In recent years, several safety briefings have successively reported shutdown accidents caused by carbon brush or rotor collector ring failure of large generator units, resulting in great economic losses to the enterprise.Carbon brushes are motor brushes. Improper maintenance and use of the carbon brush of the generator set during operation will cause accident load reduction or even shutdown. Factors leading to carbon brush fault Electromagnetic factors : when reactive or excitation current is adjusted, the spark of carbon brush has obvious change. 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...

Проектни стъпки на пружина с постоянен въртящ момент: 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...

[Qianye precision]Physical design and recoil force of constant force spring: 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. ...

carbon brush spring News

Do you know what springs are used as stop mechanisms?: We often find that the spring we make is wrongly used as a stop mechanism in the design. This design defect can occur in all types of springs, including constant force spring, constant torque spring and power spring. For example, consider a simple cable extension product in which the spring retracts the cable into the housing. If the spring is completely wound before the cable is fully deployed, the spring will be used as a stop mechanism. This action will damage the function of the spring and components and should be avoided at all costs. Here are some useful tips when considering the stop mechanism. Constant Force Spring Application: Initial designs often show the inner end of a Constant Force Spring attached to its’ spool. This is not necessary. If the spool is larger than the natural spring diameter, the spring will automatically fit tightly on the spool. In the case when a screw is attached to the spool, additional concerns arise. If the spring is pulled tight on the screw, a hump will result that will not only make the retraction difficult but will cause a fracture point and reduce life cycles. To avoid this, we recommend that the spool maintain 1-1/2 wraps of spring material at the furthest extension. If these additional wraps are not practical in the design, another method of stopping the rotation is required. Constant Torque Spring Applications: This type of motor spring is commonly used to retract a cable or to keep a constant torque rotational force on a spool. It is extremely important not...

Традиционни електрически пружини и предварително натоварени пружини: Традиционните силови пружини и предварително натоварените силови пружини са произведени от пружинни стоманени пръти за осигуряване на въртящ момент. Пружинната стомана е нисколегирана, средно въглеродна стомана или високо въглеродна стомана с много висока граница на провлачане. Предметите, изработени от пружинна стомана, могат да възвърнат първоначалната си форма въпреки значителното огъване или усукване. Силовите пружини използват плоски (ненапрегнати) стоманени намотки, докато предварително напрегнатите пружини използват предварително напрегната стомана, за да произведат по-голям диапазон на използваем въртящ момент в сравнение с конвенционалните силови пружини. По време на производствения процес пружината се навива в задържащия пръстен или в корпуса на клиента (задържащият пръстен е показан на снимката по-долу). Когато сте готови за окончателна инсталация, внимателно монтирайте пружината в нейния корпус, като външният край е прикрепен към външния ръб, а вътрешният край е прикрепен към дорника (вижте снимката по-долу). По време на работа корпусът или дорникът ще бъдат фиксирани, докато другият компонент е свободен да се върти. В зависимост от изискванията на вашия специфичен дизайн, може да е полезно да използвате фиксиран дорник/свободна кутия или свободна кутия/фиксиран дорник. Тези пружини обикновено се използват за прибиране на шнура или кабела на макарата. Може да го видите в косачки, прибиращи се въжета или каишки за кучета. Това също е типът пружина, използван за задвижване на много механични часовници и таймери, поради което понякога се наричат "часовникови пружини". Натоварването, осигурено от пружината, се увеличава с площта на напречното сечение на материала. Броят на завъртанията, които пружината може да осигури, зависи от наличното пространство между дорника и...

Design and manufacturing method of constant force spring: Design and manufacture a complete set of constant force springs for a variety of applications in almost all industries, from medical care to aerospace and general household products. The constant force spring is different from the traditional spiral wound spring. They are made of pre tensioned high-yield metal strips (usually stainless steel) rather than wires. Constant force springs are classified as "tension springs". When winding, the metal strip resists uncoiling with nearly constant resistance. When extended, the internal stress of the metal resists any load force at a nearly constant rate. Once the spring extends to a length of 1.25 times its diameter, it reaches full load and produces a nearly constant force. According to the size of the spring and the load it supports, the fatigue life cycle of the constant force spring is between 2500 and 1000000 times. Constant force springs are commonly used in automotive engineering, aerospace engineering, medical and retail. Some common applications are: Cable retractor, motor, spacecraft, fitness equipment, door closer, hose retriever, nuclear magnetic resonance scanner, X-ray machine, point of sale display, toys, furniture accessories, retractable tape measure or dog line, retractable vacuum cleaner line, etc. If you choose a constant force spring for an application, you must first consider several factors. Material selection is important, as is the thickness and width of the metal strip. The most commonly used metal is grade 301 stainless steel because it can make consistent high-quality and strong constant force springs. Other materials are available, such as high carbon steel, Inconel, etc., which may...

7 tips for maximizing spring cycle life: Spring is a kind of mechanical part that uses elasticity to work. The parts made of elastic materials deform under the action of external force, and return to the original state after removing the external force. Also known as "spring". It is generally made of spring steel, and the types of springs are complex and diverse. The following tips to maximize the service life of the spring are also of great concern to you! 1. Lower Stress, The Better! In the early design stages of a spring, try designing with a larger wire diameter or a lower final load to allow more room for the spring to improve cycle life. 2. Shot Peening A shot peened spring can handle more stressful conditions than unpeened springs. This process can greatly improve performance and sustainability. 3. Keep Cool Spring relaxation or loss in spring load occurs faster in high temperature applications due to stress over time. Reducing operating temperatures can reduce the chances of spring relaxation. 4. Using The Right Material Material selection of a spring is key to good spring design. Consult with a Lee Spring Engineer to determine if upgrading to a higher tensile range or quality grade material can improve cycle life for a particular application. 5. Minimize Shock Loading Shock loading occurs when a load is applied with sufficient speed for the first coils of the spring to take up more of the load than what would be calculated for a static situation. The more times a spring...

Видове пружини в медицински изделия: Springs are integral components in the manufacture of many medical devices. Whether it’s for a surgical stapler or a medical monitor, the types of springs in medical devices are defined by a specific action or movement required for the application. Though relatively simple in its design, springs store the mechanical energy necessary for a wide range of medical devices, machinery, and equipment to function properly. Any type of surgical instrument, medical equipment or device that has a mechanism undoubtedly has a spring component. Spring material must be medical grade, and the design and function of any device must adhere to stringent regulatory requirements and guidelines as defined by the FDA. Booms, table and bed lifts, fluid control devices, wheelchairs, medical testing and monitoring equipment either fixed or mobile, MRI and X-ray machinery, dental x-ray with articulated arms, medical equipment drawer closing mechanisms, anesthetic infusion devices, sterilization valves, various implants, and shunt valves are all examples of medical devices that require springs to function. Manufacturers of medical devices and devices subsequently relied heavily on springs in a variety of applications. The medical industry relies on the same types of springs that most industries rely on—constant force springs, constant torsion springs, power springs. Constant force spring Constant force springs are coiled with stainless steel tape so that when coiled relative to being stretched, the spring relaxes in a low stress state. When it is unrolled, the restoring force comes mainly from the portion close to the unwinding spring coil. The resultant force is almost constant. The actuators that operate in the surgical...

Приложение на пружина с променлива сила в електрическа ролетна щора: The electric roller shutter has many advantages, such as beautiful and simple appearance, firm and durable structure, etc. the roller shutter is suitable for a variety of places, such as business office buildings, hotels, restaurants, offices and homes (used as gauze curtain), especially for large-area glass curtain walls. When the roller shutter fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good sunshade effect. When the roller shutter is raised, its volume is so small that it is not easy to be detected. Have you ever thought about why the roller shutter will automatically rise and fall, and can freeze at any position without running up or down? You may not have an in-depth understanding, because the addition of variable force spring makes the electric roller shutter achieve this effect. The electric roller shutter extends from the longest to the shortest, and the weight of the lower beam changes from light to heavy. Therefore, the elastic force of the variable force spring needs to gradually increase from small to large, reaching the full stroke and gravity balance. So that the curtain can stop and hover at any position. Many variable force springs on the market can not reach the variable force spring whose force is changing at any section, so many electric roller blinds will add some components (deceleration device, damping device, gear device, limit device, etc.) to achieve the effect of perfect lifting, free positioning and free pause. Qianye often contacts with some foreign curtain industries, especially in cordless curtains and roller blinds, which...

Пружинен дизайн с постоянна сила за регулируема стойка за бюро и монитор: In order to conform to the height of ergonomics, adjustable desk and display bracket have been widely used in the market. These applications enable people to choose to work sitting or standing, and adjust the appropriate height of equipment to meet the needs of medical care. The application of these two products can not be separated from the constant force spring. Why is it inseparable? Because the function of lifting in the product is to use the principle of free lifting of constant force spring internally to design a lifter that can adjust the height at will. With the help of the tension of the spring, its height can be adjusted freely. Constant force springs are characterized by a large output force with little space requirement, applying an almost constant force throughout the stretch. The constant force spring also has the characteristics of short initial preload, that is, it can withstand the rated load at short elongation, and provide long elongation capability. All functions are ideal for use as a balancing function, not only for ergonomic height-adjustable desks and monitor stands, but also for various height-adjustment applications such as patient bedside tables, wall-mounted storage cabinets, monitor and keyboard integrations Medical workstation. Furniture and Medical Device Design Engineers If you think a constant force spring is a good fit for your application, here are some factors to consider during the design phase of your project. 1. Load conditions Constant force springs generate force as the material stretches. The rated maximum working length of the constant force spring. This means that the maximum...

Как да решите проблема с функцията за повдигане на вентилатора чрез пружина: We all know that gravity of the earth's center will drop rapidly to the bottom point when the object has no support, and it will be heavy when it rises. Similarly, when the fan moves up and down, it will also be affected by gravity. Therefore, we all hope that the fan will be more light when it is lifted and lowered; it can be easily moved up and down by hand to locate at will, and the fan will be more arbitrary when using it. Therefore, to achieve the purpose of light and arbitrary positioning, we must solve the problem of gravity There are several main points for the fan to rise and fall: 1. Life problems: Each kind of hair will have a certain life cycle. If you choose the general materials and immature production technology, the life of the products will be greatly reduced. The same with the elastic problem of hairpin, they are all related to materials and processing technology. In the process of using the fixed force, there will be problems of too short life,. 2. Elasticity: In the limited space, under the same size conditions, in order to make the hair to meet the strength requirements, we must strengthen it from two aspects to better play the effect. (1) Reasonable use of materials: In the process of production and design, we need to use the corresponding materials for processing and production according to the design of the spring. (2) Processing technology There are different processes for the same surface size of the fixed force...
