   Variable force springs and variable torsion springs can expand negative gradients and positive gradients to form a single spring. It breaks through the influence of the traditional spring affected by Hooke's law, so that the stroke and force are no longer proportionally increased, but accompanied by various elastic force-displacement combinations, such as negative slope. Therefore, a stepped constant force can be achieved. Variable force springs and variable torsion springs can be customized for various elastic curve changes according to specific applications. What products can the curve changes of variable force springs be used for?      Pen Type Drug Syringe Application The spring exerts a constant force to keep the drug flow in place, preventing patient discomfort during use. It has a stretch at the end of the stroke to ensure that all of the medication can be fully injected.      up and down sliding door     When the door is closed, the spring force is less than the door...

Физическият принцип зад пружината с постоянна сила

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...

Проектиране на пружини с постоянна сила

 A constant force spring is a spring that exerts a constant force over its range of motion. That is, it does not obey Hooke's law. Typically, a constant force spring is constructed as a coiled band of spring steel so that the spring relaxes when fully coiled. When it is unrolled, the restoring force comes mainly from the portion of the belt that is close to the roll. Since the geometry of this region remains nearly constant as the spring unfolds, the resultant force is nearly constant.       By creating a spring with a variable pitch, you can make a push-shape spring with a constant velocity. Placing a larger pitch in a larger outer diameter coil and a smaller pitch in a smaller outer diameter coil will force the single spring to fold all coils at the same rate when compressed.       Design of Constant Force Springs: A constant force spring is a coil of prestressed...

Традиционни електрически пружини и предварително натоварени пружини

   Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while pre-stressed power springs use pre-stressed steel to produce a larger range of usable torque than conventional power springs.        During the manufacturing process, the spring is wound into the retaining ring or the customer's housing (the retaining ring is pictured below). When ready for final installation, carefully install the spring into its housing with the outer end attached to the outer edge and the inner end attached to the mandrel (see photo below). During operation, the housing or mandrel will be fixed while the other component is free to rotate. Depending on the requirements of your specific design,...

Предимства на безжичните пружинни компоненти Qianye

All curtain cords, whether installed on the side, caught in curtains, or placed on the back, can be dangerous to children. It is best to replace all corded curtains with cordless curtains in houses where children live or visit, especially in children's bedrooms and play areas. Cordless roller blinds with either a spring system or an electric system can improve the safety of the home.        Cordless roller blinds with spring system are similar to movie curtains. They use the elasticity of the springs. Under the action of the spring components, the roller blinds can be balanced at any position and can be stopped at any time.        At present, most of the spring components on the market are wire spring cordless curtain systems, which have a relatively short service life and a high degree of force attenuation. When pulling down, the curtain stops at each clip, and when rising, pulling down makes the curtain bounce...

Пружини с постоянна сила, използвани в аксесоари за стенен монтаж

As more and more people spend more and more time using computers, computer users spend more time sitting or standing at their desks or workstations in front of devices. Keeping what experts call "the best ergonomic positioning" can improve energy levels and overall comfort. For this purpose, the input and output devices must be placed in appropriate positions. The proper position can reduce the muscle strain of the user's arm and effectively prevent various musculoskeletal diseases, including carpal tunnel syndrome, neck pain, and upper and lower back pain.   The attachment bracket can be used to facilitate the support and position adjustment of the fixed attachment. The attachment retainer allows simple three-dimensional adjustment of two such devices to place the devices in a more ergonomic relative position to meet the needs of various users and workspaces, and has a balancing mechanism for balancing the weight of fixed attachments.   The balance mechanism provided by the wall mounted accessories is superior to the traditional lifting system,...

Пружината с постоянна сила се използва при отстраняване на имплантиран обект с помощта на лазерно изрязани хипотръби

Отстраняването или изваждането на оловото може да е трудно. Както бе споменато по-горе, естественият процес на оздравяване на тялото образува тъкан от белег над и по протежение на оловото и вероятно на върха му, като по този начин обвива поне част от оловото и го закрепва още по-сигурно в тялото на пациента. В допълнение, оловото и/или тъканта могат да се прикрепят към съдовата стена. Следователно и двата резултата могат да увеличат трудността при отстраняване на проводниците от васкулатурата на пациента. Устройство за отстраняване на имплантиран обект от телесен съд може да включва комплект обвивка, включващ комплект външна обвивка и модул вътрешна обвивка, и щифт, като комплектът външна обвивка включва външна обвивка и външна лента, като външната лента е свързана към щифтът, модулът на вътрешната обвивка, включващ вътрешна обвивка и връх, при което върхът има режеща повърхност, вътрешната обвивка включва проксимален край и дистален край, при което отдалеченият край на...
