How to choose double torsion springs suppliers, what is double torsion springs
A torsion spring is a coil spring that stores and releases angular energy or holds a mechanism in place. They feature two legs extending from each end of the coil and are used in applications requiring torque or rotational force. This is accomplished by attaching the legs to external components. Then, as the elements rotate around the spring, the spring tries to push them back to their original position. Torsion springs come in a variety of different shapes and sizes, with different leg configurations and lengths, for a wide range of applications. Typical uses include automotive door handles, garage doors, clothespins, bulldog clips and hinges. In some cases, a single torsion spring cannot exert enough force. In these cases, a double torsion spring may be required.     What is a double torsion spring? As the name implies, a double torsion spring is characterized by two torsion spring coils joined at the center to form one spring. The two coils...

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...
How long can constant force spring be used ?
How long can constant force spring be used ?
Constant force spring, also known as hair spring, is made of stainless steel strip. The force added to the spring determines the diameter, force and life of the spring. The action of constant force spring is similar to that of stretching ribbon. The spring stretches and rolls back, and the working part is tangent to the spring ' s own circle. As long as the diameter of the spring is certain, the force of the spring is constant. According to the application principle of constant force spring, constant force spring can be divided into linear constant force spring and rotational constant torque spring. When linear stretching force units are : kg, Newton, pounds, etc.     Then how long can the constant force bar be used ? The life of the constant force bar is limited, and the life requirement of the spring should be considered when designing the constant force bar. This step is important because it affects the...
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.  ...
What is passivation? Does my product need it?
What is passivation? Does my product need it?
 "My new stainless steel product specification requires' passivation '. Do I need it?" Our answer is that you may not. That's why. Passivation is the process of protecting stainless steel from corrosion by adding an oxide layer on its outer surface. Although some stainless steel product specifications require passivation to reduce corrosion risk, most of them are unnecessary and expensive, and may damage some metal products, including flat bar springs, such as constant force, variable force and constant torque springs, all of which are uncommon products manufactured by Qianye precision.     The reason passivation is not a good idea for flat bar springs is because passivation involves the use of acids and harsh chemicals to initially clean the metal as part of the process. The geometry of these spring types means that many small cracks can form between the coil layers. The acid used in passivation can become trapped in these crevices. This resulted in longer-than-expected exposure of the...

The surgeon can operate the controller on the console to indirectly operate the instrument connected to the remotely operated actuator. The instrument can be disassembled from the remotely controlled actuator, so that the instrument can be disinfected separately and selected to be used as the instrument required for surgery. Combine. Instruments may be changed during surgery.   Using remote instruments for surgery brings new challenges. One problem is to provide a remotely operated motor mechanism that supports a remotely operated actuator that can be positioned relative to a patient. These features are quite heavy and may weigh between 12 and 24 kilograms. The mechanism must be moved over the patient and carefully positioned. Therefore, it is necessary to balance the surgical instrument, the associated actuator, and the support structure so that the surgical instrument can be safely and easily positioned. The constant force spring is made of stainless steel strip, so that when it is rolled up relative to being stretched, the spring will relax in a low stress state. When it unfolds, the restoring force mainly comes from the part close to the loosened spring coil. Specifically, the force comes from the region that transitions from a circle to a plane. The force does not come from the part of the drum that is fully unfolded or still winding. The resultant force is almost constant because the geometry of this area...

There are many types of curtains on the market today, such as Venetian blinds, Roman blinds and honeycomb blinds. When the curtains are lowered, the windows can be shaded to reduce light entering the house and improve privacy. Generally speaking, curtains are provided with control ropes, which can drive the bottom rail of the curtain to rise or fall. In particular, the bottom rail is raised by a roller take-up hanger, and the hanger can be extended from the roller so that the bottom rail can be lowered.        However, the problem that the control cord may restrain children has been noted, so a cordless curtain has been developed. This cordless curtain can raise and lower the bottom rail by means of a coil spring box. Coil spring boxes used in window blinds usually consist of multiple springs that provide torsion to maintain the bottom rail at the desired height. However, the assembly of such a coil spring box is usually complicated, and the torsion force of the spring must be transmitted to the drum through a plurality of moving parts, which disadvantageously increases the weight of the coil spring box in the curtain.        Therefore, a cordless spring component developed by Qianye Precision can overcome the above shortcomings. Cordless roller blinds can balance the roller blinds at any position under the action of the spring components according to the high and low positions of the roller blinds, and achieve the purpose of stopping at any time.

The reason why the world we live in is so orderly is that there are precise links between large and small objects. So many things in life are crucial. Whether they are large or small, they are indispensable to our life, but some small parts in life are unknown, but there are tens of thousands of them. The spring I know is also one of them. It always exists in a position that people can't see and does their own thing silently. Moreover, he exists everywhere in life, even if we don't know it. Today, I will explain the functions of these small springs. Spring is a kind of mechanical part that uses elasticity to work. Generally made of spring steel. Although the spring is small, as a general basic part, it has large quantity, wide range and complex varieties.
