Congratulations on the return of Shenzhou 13 spacecraft

Ora: 14-9-2022

At about 10 am on the 16th, the "Shenzhou 13" manned spacecraft landed smoothly, and the three astronauts who had been on a business trip for half a year also returned safely, and the hearts of many people also fell to the ground. At the same time, Yang Liwei's voice that appeared in the live broadcast room also made many people's soul wear 2003. Recalling that when the "Shenzhou V" was successfully launched in 2003, the first batch of post-90s generation was just thirteen years old. "Shenzhou No. 5" may already be a term with a sense of age for the late-born children of Generation Z and Generation Alpha. Mankind's curiosity and desire to conquer space have never stopped. What does the vast universe look like with human naked eyes? Is it really romantic and exciting to be in space as outlined in science fiction films? Is space really desolate and silent?      Because outer space is full of all kinds of mysteries, human beings may be afraid to see the deep universe in outer space, especially when they float in outer space when they get out of the cabin. Therefore, when the astronauts leave the cabin, they are tied to the astronauts with an 18 meter long rope and connected with an oxygen pipe to provide life support for the astronauts. If the astronauts do not grasp and drift, they can use this rope to return to the space station. Fortunately, our Qianye precision has also made a small contribution to the national aerospace industry. We are mainly involved in...

Do you know about the constant force spring module?

Ora: 14-9-2022

 I'm sure many of you know what a constant force spring is, right? A constant force spring is a spring that maintains a constant spring force for a specific stroke, also called a constant force spring, and is used in a linear motion, usually using its rebound force. A constant force spring consists of a spiral-shaped metal sheet that is bent on the inside so that each coil is wound tightly around the innermost coil of the metal sheet. When the metal sheet is stretched, the internal stress resists the load force, which is exactly the same as a normal extension spring, but the spring force is very constant and can output a nearly linear spring force.   The use of a constant force spring on the lift support enables the supported structure to hover over gravity at any position during the allowable travel.   However, in order to achieve a variety of functions and operations, the supported structure, such as a monitor, usually weighs more than the white body of the device. In order to ensure a large support force, the constant force spring needs to use a thick elastic metal sheet. However, the thick elastic metal sheet will lead to a short effective constant force spring travel.   The purpose of this constant force spring die set is to provide a constant force spring die set that is capable of maintaining a large constant force lift value and a constant force effective stroke within an effective mounting space. Another purpose is to provide a constant force spring lift mechanism that not only provides a greater constant lift force, but also reduces the mounting space of...

Application of carbon brush spring in wind turbine slip ring brush holder

Ora: 14-9-2022

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...

Principio fisico alla base della molla a forza costante

Ora: 14-9-2022

When you walk into your office building on your way to work every day, or into your local bank, or any commercial facility, you may open a heavy glass door. When you cross the threshold, the door closes behind you, and you don't think about it. However, the heavy glass door was probably closed by a constant force spring. Constant force springs are widely used in daily applications. From door closers to rope and hose retractors, to sports equipment, toys, motors, etc., constant force springs exert force at an amazing high frequency and consistency. Let's take a closer look at the basic physics behind the constant force spring. In the 17th century, the British physicist Robert Hooke proposed a formula for force and elasticity, which is now called Hooke's law. Hooke's law states that the force (f) required to stretch or compress a spring for a distance (x) varies linearly in proportion to that distance. The formula is f=kx, where k is a constant and represents the stiffness of the spring.   Constant force springs in terms of actual spring performance, Hooke's law is nominal. In the equation, the distance X that the spring moves is a relatively small number. Finally, any elastomer that is stretched or compressed beyond the stress limit of its material composition will show signs of deformation. Therefore, the force properties that depend on the consistent shape and tension state will change in the deformation state. Ideally,constant force springs will exert a consistent force over a given range of motion, repeating without changing. In fact, constant force springs, like all elastomers, are limited...

Una molla a coppia costante può svolgere un ruolo così importante nel dispositivo di raccolta

Ora: 14-9-2022

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. Many take-up devices on the market are prone to dislocation or jamming during take-up due to the improper selection of spring, resulting in confusion and low take-up efficiency. Shenzhen Qianye Precision Metal Co., Ltd. has been specializing in the production of spring for more than 20 years. Qianye precision spring engineers can help you improve and improve your products. Contact us at any stage of your project for expert help and technical...

Advantages of constant force spring on computer lifting table

Ora: 14-9-2022

Now people's working hours are getting longer and longer, and everyone is working hard. Some workaholics want to live on their desks. As people sit and work longer and longer, people gradually realize that sitting for a long time is not conducive to the improvement of work efficiency. People begin to try to sit and stand alternately, and gradually the lifting table appears, Using the lifting table to work in a station has become a popular and healthy way of working. The lifting and lowering of the computer lifting table mainly depends on the lifting system. The accessories used for lifting and lowering are constant force springs. The quality of the constant force springs determines the user experience. If you want to buy it, it will break down after a while, or if you want to rise or fall when you use it, it will fall down automatically when you reach a position. Will you still buy this kind of computer lifting table? Therefore, when choosing constant force spring manufacturers, we should choose a mature industry and choose high-quality manufacturers. Generally, there will be no quality problems. Constant force spring is made of stainless steel strip. The high-strength steel strip is shaped through specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force. However, when our goal is achieved, it can return to the starting point specified by us after displacement. It is applied to products requiring linear motion such as round-trip, sliding, stretching, homing, balance or labor-saving. Compared...
