In order to prevent accidents caused by excessive wear of the carbon brushes on the collector device of the slip ring brush holder of the wind turbine, a normally closed switch-type alarm unit is configured for each carbon brush, and these alarm units are connected in series to the alarm. In the prior art, the grounding brush is held on the structure using a coil spring pressure finger lever structure. In order to ensure sufficient pressure after the carbon brush is worn, the initial pressure of the spring has to be increased, which aggravates the wear of the carbon brush. However, in the later stage of carbon brush wear, the tension of the coil spring becomes insufficient again, resulting in poor contact between the carbon brush and the slip ring, frequent beating, resulting in breakage; at the same time, from the carbon brush to the alarm unit, the intermediate link is complex and easy to Lead to false alarm or no alarm, reducing the reliability of the system. In order to overcome the shortcomings of the prior art, a novel slip ring brush holder collector of wind turbine generator with simple structure, reduced wear of grounding carbon brushes and reliable operation is provided. The slip ring brush holder collector of wind turbine includes slip ring, brush holder, main carbon brush and grounding carbon brush, and the pressure end of the grounding carbon brush with alarm pressure piece is pressed by a coiled constant pressure spring. The constant pressure spring grounding brush holder structure greatly improves the force on the carbon brush during operation and...
 [Qianye precision]Physical design and recoil force of constant force spring
[Qianye precision]Physical design and recoil force of constant force spring

Time:2022-9-15

 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.    Hooke's law does not apply to constant force springs because their recoil force remains constant over the entire range of motion. This is achieved through its unique physical design, which consists of thin and curly steel strip. The constant force spring is in a relaxed state when it is fully rolled up, and is loaded when it is partially or fully unfolded. After release, the spring rebounds by pulling the extended carbon belt back into the tight coil. Since the recoil force mainly comes from the part closest to the coiling roll, a constant force can be maintained.   Common applications of constant force...

3D printing, also known as three-dimensional printing, is a kind of rapid prototyping technology. It uses adhesive materials such as powdered metal or plastic to construct zero objects through multi-layer printing layer by layer. Mold making, industrial design is used to build models, and is now developing into product manufacturing, forming "direct digital manufacturing". Some high-value applications (such as hips or teeth, or aircraft parts) already have printed parts. The constant torque spring is applied to the 3D printer. This innovative case is a spring motor drive system. Like the common design, it is impossible for a spring to achieve the torque we need. As you can see we are using three constant torque springs in one mechanism with an output drum in the middle connecting the three springs. Therefore, it can generate three times the output torque of only one spring, and this design can achieve the purpose of providing maximum torque in a limited space. This connection method is easier to assemble than using screw connections.        When it comes to spring design, design engineers must consider many factors. These factors include not only part function and mechanism design, but also detailed material selection, part connection installation method and size. It's all about manufacturability. Feasibility analysis is required to ensure the functionality meets the customer's needs.        From the initial design stage of the spring set to production and final assembly, Qianye can save customers product development time, find optimized solutions beyond your expectations, no manufacturability constraints in product design, and the best product...

 Spring to ensure good elastic performance, that is, absorb a lot of elastic energy without plastic deformation; Sufficient plasticity and toughness to prevent impact fracture. According to the stress nature, the spring can be divided into tension spring, compression spring, torsion spring and bending spring. According to the shape, it can be divided into dish spring, ring spring, plate spring, spiral spring and truncated cone scroll spring.       The design process of spring has the following points:      1. Device space: design a compression spring, clearly understand the space required to install the spring, and then you can master the basic manufacturing conditions, outer diameter, inner diameter and free length of a compression spring.      2. Movable stroke load: the design of compression spring to clearly understand the position to be actuated and the elastic force to be carried. Determine the position and know the required elasticity, then you can determine the material, wire diameter and number of turns.    3. Environmental factors: when the spring is actuated in different environments, it will be affected by environmental factors and affect the service life. Therefore, the designer takes into account the changes of ambient temperature and humidity. The temperature has a great impact on the service life of the spring, and the humidity is easy to oxidize the spring without surface treatment. Therefore, environmental factors can determine whether the spring needs surface treatment and material selection.      4. Distance space between two ends: stretching the points at both ends of the spring will affect the form of the hook and...

Constant torque springs can help take up the wire and are used in many products. All electrical products have a cord set that is connected to the power supply, but this power cord will bring some trouble to our arrangement. The function of the constant torque spring is this, it can bring a free shrinkage process to the electrical cord set , making it easy to take up the line, very practical. When the external force reverses the constant torque spring from the natural state to the output wheel, once the external force is removed, the constant torque spring will be rolled back to the natural state, and a constant torque will be generated in the output wheel at the same time. Constant torque spring can be used in automatic winding, balance weight and power source, such as automatic winding device of power line. Advantages of constant torque spring over power spring: 1. The torque will not change as the number of turns increases. 2. There is no limit on the number of available turns, and the design of multiple turns mostly adopts constant torque spring.  3. The number of invalid turns is less, more energy can be stored and the efficiency is higher.

Spring is a commonly used component in industry. It is used in all kinds of products, from aircraft and warships to mobile phones and cameras. Therefore, the production of spring has a history of hundreds of years. Constant force spring has the characteristic of maintaining constant force in long stroke. Its function can be applied to the application of products that need linear movement such as round-trip, sliding, stretching, homing, balancing or labor-saving, such as lifting doors and windows, computer display and fan height adjustment, store display shelf or motor carbon brush motor. On the market, constant force spring manufacturers generally use eight claw spring machine, which is called eight claw machine for short. The eight claw spring machine is continuously developed on the basis of three axes. The eight position claw arms of the eight claw spring machine can rotate 360 degrees in the forward and reverse directions. The working sequence of the curved arms is determined by the shape or angle of the cam plate, and then the auxiliary tools such as curve gauge, angle bender, collision knife or cutter are used to complete the processing of spring products. The surface of the constant force spring produced by the eight claw machine will be rough, the force value is unstable, it is easy to loosen the ring, and the service life is relatively short.         However, Qianye uses the spring coiling machine. The constant force spring produced by the spring coiling machine can meet the strength requirements in a limited space; Qianye also strengthens from two...

As we all know, although the spring is only a small elastic accessory, it plays an important role in life, and the quality of the spring has a great impact. Most springs are customized products, so the process of customized production cannot be careless. When purchasing a spring, customers usually need to design the data of the product first, and communicate with the engineer to draw the drawing, so as to communicate with the spring manufacturer more clearly. Drawing the spring drawing is an important step before purchasing the spring accessories, and it is also an important step of customizing the spring engineering. The detail of the drawing directly affects the quality and effect of the spring products. Secondly, customers should carefully screen suppliers. If spring products are used, then spring manufacturers need to carefully screen and select suppliers that are suitable for you through comparison. There are many spring manufacturers on the Internet. It is more important to choose manufacturers with relatively good quality and reputation to cooperate. You can also know whether the selected suppliers are suitable for you through on-site investigation.   Finally, customers should also pay attention to the material comparison of spring accessories. When choosing the spring manufacturer to cooperate in the production of spring accessories, you can conduct technical exchanges with the spring manufacturer, listen to the suggestions of the other party, and combine your actual application to select the spring raw materials suitable for us, whether constant force spring, power spring, variable force spring, motor brush spring, constant torque spring or some special springs, As professional manufacturers...

Analysis on the causes of carbon brush fault of generator set

Time:2022-9-15

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 is not equal ; carbon brush quality issues, etc. Mechanical factors : commutator center is not correct, rotor imbalance ; large vibration of the unit ; insulation bulge between commutators or commutators bulge ; carbon brush contact surface grinding is not smooth, or commutator surface roughness caused by poor contact ; the commutator surface is not clean ; the air gap under each reversing pole is unequal ; spring pressure on carbon brush is uneven or unsuitable ; carbon brush in the brush grip too loose and jump, or too tight carbon brush in the brush grip stuck, etc. Reduced operating...
