A constant torque spring can play such a big role in the take-up device
A constant torque spring can play such a big role in the take-up device
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...

Do you know what springs are used as stop mechanisms?
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...

 Small engines are well known and are commonly used in lawn mowers and garden tractors and various other garden and lawn maintenance tools, in addition to other environments. Typically, each of these engines is equipped with a recoil starting system that includes a rope that rotates the starting mechanism to engage a flywheel that is connected to the engine for starting purposes. Once the rope starter is pulled, the recoil mechanism is always provided with the engine to reel the starter rope back to the starting mechanism.   The recoil portion of the starter mechanism is operated by a power spring that tensions when the operator pulls on the starter rope. Once the rope is fully pulled, the operator releases it. Most power springs on the market often fail, so the recoil rewinding mechanism needs to be disassembled and the spring replaced. And replacing the spring is a tedious task because the operator needs to keep the spring in the cavity inside the recoil starter pulley and then coil the spring into the pulley mechanism while keeping the spring in the coiled position and under sufficient tension. Such a procedure requires not only skill, but sometimes infinite patience. That's why the quality of the power spring is a top priority - after all, no one wants to change the power spring inside too often.   Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 20 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable...

 Analysis on the causes of carbon brush fault of generator set
Analysis on the causes of carbon brush fault of generator set

Heure: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...

In order to make the refrigerator operate effectively, the door should be kept closed. Keep the door open for a short time when putting or taking out food. However, opening it for a long time will affect its cooling and endanger food safety. It will also lead to excess power consumption. Fortunately, the modern refrigerator door can be added with a constant force spring to automatically close after you open the refrigerator for use. Nowadays, this kind of design is relatively rare in the market. It is generally a magnetic refrigerator door, which explains why the magnet is attached to it.   We have seen that it is essential to keep the refrigerator door closed all the time. If the door remains open for a long time, it will counteract the internal temperature balance and affect the quality of the food stored in it.When this situation continues for a long time, the compressor cannot maintain a low internal temperature. This undermines its operational efficiency. In addition, the longer the door is opened, the hotter the inside of the refrigerator will become.   Because it is very important to keep the door closed, a constant force spring is added to the refrigerator door. If you open them, they will close automatically.A constant force spring is added, which pulls the door back and seals it tightly to the frame when the door is opened. Constant force springs are often the best spring type for this application and can be manipulated in a number of ways to ensure your design works. Constant force springs are characterized by a...

 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...

 Nowadays, the quality of life is getting higher and higher. Bicycle no longer exists as a means of transportation, but has become a fashionable fitness product. People who play with cars have a saying: if you want to keep your car, you don't need a car lock. Where do you put your car when you get home? Especially for people like me, who have two children and are very short of room, where to put the bike at home has become a headache.      In order to solve this problem, foreign designers have designed a parking rack, which can easily save you 40% of the use space in one step, and it is very labor-saving. The traditional hanging frame requires you to lift the car hard before you can put it on. As long as you push the hanging frame to the card slot, the hanging rack will rise automatically, and even the elderly can hang the car easily, When you need to ride, just pull your car back and the hook will fall automatically.      Of course, some people will certainly ask that there is a sensor.
