/product/torsion-spring-c-14.html Helical springs used to apply a torque or store rotational energy are commonly referred to as torsion springs. The ends of torsion springs are attached to other components, and when those components rotate around the center of the spring, the spring tries to push them back to their original position. Although the name implies otherwise, torsion springs are subjected to bending stress rather than torsional stress. They can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centerline axis. This type of spring is normally close wound but can have pitch to reduce friction between the coils. They offer resistance to twist or rotationally applied force. Depending on the application, torsion springs can be designed to work in a clockwise or counter-clockwise rotation, thus determining the direction of the wind. Applications: Common torsion springs are used in clothes pins, clipboards, swing-down tailgates, garage doors, window shades, counterbalance mechanisms, ratchets and various types of machine components. Torsion springs are used for hinges, counterbalances and lever return applications. They are also used as couplings between concentric shafts, such as in a motor and pump assembly. Torsion springs are generally mounted around a shaft or arbor, and must be supported at three or more points. Various kinds of ends are available to facilitate mounting. Sizes range from miniature, used in electronic devices, to large torsion springs used in chair control units.Load should be applied in the direction of wind; unwinding from the free position is not recommended. As they wind up, torsion springs reduce in diameter and their body length becomes longer. This should be considered when design space is limited. Torsion Springs perform best when supported by a rod or tube. The designer should consider the effects of friction and arm deflection on the torque. Torsion Spring Terminology Angular Deflection - is the angle of rotation as measured from the free position to the installed, intermediate or final positions. Free Angle - is the angle between the arms of a torsion spring when the sprin

/product/torsion-spring-c-382.html Twirl torsion springs exemplify its “complete spring” concept with many options as standard, covering angular orientation and many leg types to suit common applications. They are extremely useful as a way of returning energy axially around a mandrel or within a cavity or similar locating framework. Commonly torsion springs are used in clothes pins, clipboards, swing-down tailgates, garage doors, window shades, counterbalance mechanisms, ratchets and various types of machine components. Torsion springs are used for hinges, counterbalances and lever return applications. They are also used as couplings between concentric shafts, such as in a motor and pump assembly. Sizes range from miniature, used in electronic devices, to large torsion springs used in chair control units. Twirl torsion springs are designed and wound to be actuated rotationally, and to provide an angular return force. There are many options for leg configuration so the spring can be attached in different ways. Leg end style choices include straight torsion, straight offset, hinged, short hook ends, and hook ends. Torsion spring ends can be bent, twisted, hooked or looped to suit your project needs.  torsion compression spring Double torsion springs consists of one set of coils coiled right hand and one set of coils coiled left hand. These coils are connected, usually with an unwound section between the winds and work in parallel. The sections are designed separately with the total torque being the sum of the two. They are particularly valuable where a balanced twist-free force is required in delicate mechanisms. torsion compression spring

Compression Spring (Compression Spring) is the first variant of the spring, from straight, tapered to reduced waist, convex waist, and even a variety of tail changes, which can be designed according to the design. Compression springs are the most widely used of all spring types. Its products are used in a wide range of industries, including electronics, motors, computers, information, steam locomotives, bicycles, hardware tools, gifts, toys and even the defense industry. The design and prin

When designing the tension spring, the coil is tightly touched, the purpose is to promote the rotation and make the angle rebound. There are many options for the arm configuration, so that the spring can be fixed in different ways. For tension springs, the moment arm specifications that need to be considered include moment arm angle, equal moment arm length, and moment arm closing type. When the springs are straight or parallel on the same side, the arm angle is regarded as 0°, and the angle increases along the non-rotating direction. Force arm closing types include straight torsion, linear offset, hinged, short hook closing and hook closing. In order to meet the application requirements, the closing opening of the tension spring can be bent or distorted, and the closing opening may be made into a hook or a pull ring. The orientation of the free arm of the tension spring includes: 90°, 180°, 270° and 360°. The double torsion spring consists of a set of right-hand rotating coils and a set of left-hand rotating coils. These coils are usually connected by the unclosed parts between the windings, and these coils rotate in parallel. This part needs to be designed separately, and the total torque is the sum of the coils at both ends. Where are the tension springs mainly used? When in use, the bottom part of the tension spring is often fixed to other places, which constitutes the phenomenon that other components rotate around the center of the tension spring. Once the other components start to rotate around the center of the spring, the spring quickly pulls the other components back to the original position, which will constitute a kind of rotational force, which changes the generated rotational force into the required resistance. In this way, the tension spring can be used to fix a certain device in a static way by storing or releasing this energy to achieve the desired effect. Of course, if the place of application is different, the number of turns of the tension spring is also different. Therefore, a lot of physics and mathematics are touched here. After the resistance required to fix the equipment, the number of turns required for the tension spring is

In life, tension springs can be seen everywhere, and they are used in many jobs. tension springs are cleaned and polished in daily use. 1. Take an appropriate amount of clean water, and mix and dilute the cleaning agent A and clean water in a ratio of 1:1 or 1:2. Put the diluted solution in a plastic container for later use. Put the tension tension spring to be cleaned into the container to soak. The soaking time should not be too long. When the surface of the tension spring has no oil stains and restores the original metallic color, take it out and use it. The clean water opens the scouring, so that the surface layer has a matte actual effect. 2. Take some coarse abrasives, put them in the cleaning agent, and then put them into the hexagonal drum. The volume ratio of the tension spring to the coarse abrasives is 1:3, and the amount of cleaning agent is 1%-2% of the tension springcomponent. It is opened in the inside for plenty of grinding, and then cleaned with water, so that the scratches on the surface of the spring will not exist. This operation can improve the surface finish of the spring very well, but it is not suitable for the use of high-precision tension springs. Under some operating conditions, this situation may also be encountered. When the operating medium or industrial products produced, even if a trace of a certain or certain metal ion is contained, it will affect the chemical process and industrial products. Quality (including gloss, color, purity, etc.). This situation is most common in industries such as nuclear fuel pharmaceuticals and pigments. At this time, the corrosion resistance levels that do not contain a certain element or are properly run are used to reduce the metal ions to the allowable limit.

Tension spring refers to a spring that can work in weakly corrosive media such as electronics, air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts. In many working environment requirements such as chemical machinery and electronics, it is an elastic element that is corrosion-resistant, resistant to medium temperature and non-magnetic. The tension spring can produce relatively large elastic deformation when it is loaded, converting mechanical function or kinetic energy into elastic potential energy. When unloaded, the deformation of the tension spring will disappear and return to its original state, transforming the deformation energy into mechanical function or kinetic energy. Tension spring has excellent general functions, such as: mechanical function (especially elastic limit, strength limit, yield ratio), elastic reduction function (that is, elastic reduction function, also known as anti-loosening function), fatigue function, hardenability , Physical and chemical functions (heat resistance, low resistance, oxidation resistance, corrosion resistance, etc.). In order to meet the above functional requirements, the tension spring has excellent metallurgical quality (high purity and uniformity), excellent appearance quality (strict control of appearance defects and decarburization), precise shape and size. Generally, cylindrical springs are simple to manufacture, so they can be made into various types according to the load conditions, with simple structure and the most widely used. Generally speaking, tension springs should have high elastic limit, fatigue limit, impact toughness and excellent heat resistance and corrosion resistance. Commonly used spring wire with a diameter of less than 20 mm is cold-rolled. After the tension spring is made, it must be pressed or polished to improve the load-bearing capacity and surface finish of the spring.
