       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...

Analysis on the causes of carbon brush fault of generator set
Analysis on the causes of carbon brush fault of generator set
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...
Design steps of constant torque spring
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...
[Qianye precision]Physical design and recoil force of constant force spring
[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.  ...

   It has to be said that laziness is a major driving force to promote scientific and technological progress. The emergence of a series of smart appliances not only makes people's life intelligent and convenient, but also gives everyone more opportunities to "be lazy" to complete other work or things. The charm of smart appliances lies in the linkage control between devices and the configuration of scene mode. It only takes one step to control household appliances to achieve the expected effect, which is the most attractive.   At present, in the aspect of smart home decoration, a kind of automatic rolling curtain is more popular, which is also called electric rolling curtain. This is an electric rolling curtain structure with tubular motor as the power. It is quite simple to operate. It is controlled by remote control or mobile phone APP. As an upgrading alternative product of manual rolling curtain, its work is more quiet and stable.

At the same time, it also has the functions of anti-ultraviolet, environmental protection and energy saving, saving indoor space and...
 The power spring makes the tape measure shrink freely
The power spring makes the tape measure shrink freely

시간:2022-9-14

Tape measure, I believe everyone is familiar with it. Tape measure is a common measuring tool in our daily life and work. After the tape measure is pulled out, it can be rolled up because there is a power spring in the tape measure. When pulling out to measure the length, it actually lengthens the length of the scale and spring. Once the measurement is completed, the spring in the tape measure will automatically shrink, and the tape will also shrink under the action of spring force, so the tape measure will roll up. The power spring is an elastic fitting in the tape measure. The end of the steel bar scale is connected to the front end of the spring, and the end of the spring is fixed in the middle of the tape measure. The tape measure mainly uses the energy storage characteristics of the spring, which can be said to be the conservation of mechanical energy .When you pull the tape measure, you work on the internal spring, and the energy is stored by the power spring; when you release it, the spring relaxes, releasing energy and causing the tape measure to retract automatic contraction uses the lever torque principle: in the stretching state, the force arm is the smallest and the spring output is the largest; in the retracted state, the force arm is the largest and the spring output is the smallest.         When the scale is pulled out, the spring is tightened to produce a force to roll back. When the tension of the scale is released,...

No matter how small the shower room is, it is also recommended that you install a bath stool directly on the wall, which is stable and convenient! I've seen a social news before. It's about a pregnant woman who took a bath at home and slipped and had an accident. To be honest, no one wants this to happen, but because many detailed problems were not paid attention to during the decoration, it led to a series of problems! In fact, when decorating the shower room, we must take safety measures. Not only families with elderly, children and pregnant women, but also ordinary people need a safe environment for bathing. After all, the shower room is a place with large water consumption. It doesn't pay to fall and hurt! The first step of safety measures is to choose anti-skid bricks on the ground. Secondly, for families with elderly, children and pregnant women, it is best to install a bathing stool. Don't think the bath stool takes up space. It has many functions! And only one square meter of space can also be installed, directly installed on the wall, stable and convenient! At ordinary times, the bath is standing and washing. It is inevitable that there will be tired and uncomfortable after a long time. If there is a place in the shower room where you can sit and rest, it is absolutely convenient and comfortable. You can not only sit and rest, but also sit in the bath. For example, when rubbing your legs, you don't have to bend down...

As everyone who knows our company knows, our company also has another product, that is, dog walker! The power spring is the core and main component of the dog walker. The power spring is made of 301 stainless steel with high precision and high hardness. Its thickness tolerance is controlled in the range of 0.01mm and its hardness is hv580 degrees. The service life of the dog walker can be extended to 30000 to 100000 times. When this power spring is applied to the dog walker, the quality of the dog walker has been greatly improved. When walking the dog, we need to pay attention to bring the dog's little partner - the dog walker, and then the obedient dog should also bring the dog walker. Don't expect the bridge section of the dog looking for the master in the movie to happen. Before using this kind of traction rope, I always used a fixed 1.5m long rope. Usually I use the traction rope to prevent dogs from running around and attacking pedestrians. But there was once a time when walking a dog. Now many shared bicycles and electric vehicles often shuttle back and forth at a fast speed when walking around the corner. An electric motorcycle brushed past the dog. Fortunately, after the rope was shortened, it was able to effectively protect the dog and prevent accidents. However, many friends would say that it would be good to buy a shorter rope? But in fact, many times we need to give dogs enough range of activities, so this time can reflect...

Mention of diabetes, I think everyone is not strange. Data show that by the end of 2021, the total number of type 2 diabetes in China was about 120 million. When oral hypoglycemic agents are standardized and blood glucose control is still unsatisfactory, insulin injection is an inevitable choice for the treatment of type 2 diabetes. Many may not know that insulin injections require dedicated syringes. Some kids are worried. Does injection take technical issues into account ? Actually don 't worry at all, because what, because the use of the Qianye  power spring ! Qianye power spring can provide small and highly accurate drug dose. The quantitative drug is injected into the body through the spring fixed force, thrust and homing speed. The thrust distribution of the steel strip spring accurately matches the sliding force of the traditional syringe. It solves the problem of emission tolerance of the syringe and provides a high thrust demand for highly viscous solution.     The device of insulin injection pen consists of handle, needle cap body, trigger device, insulin needle, needle hole and dynamic spring. The trigger device is started by the button to make the spring inside the needle cap contract instantaneously, and the spring elasticity drives the needle to penetrate into the subcutaneous tissue at a certain depth instantly, so as to effectively relieve the fear and pain of the patients, reduce the trauma area, improve the treatment compliance, enable the patients to carry out effective site rotation injection, and improve the treatment effect.  The reason why insulin injection needs special syringes...
