Types of Springs
Springs are very common in many different products in a wide range of industries. They come in all kinds of shapes and sizes and a common trait they all share is their usefulness. From the toy industry to aerospace and automotive, springs are a critical piece for so many products. Springs can be found in all kinds of machines, from household appliances to heavy industrial equipment. They store mechanical energy and are used in many popular applications. In this post, we’re going to discuss different types of springs and how they’re commonly used.
As opposed to being compressed, torsion springs are wound tightly like an extension spring, or pitched, and pre-loaded to store energy. The ends typically extend away from the spring body in a non-helical shape and many are produced as a result of engineering concerns about friction developing between coils. Some types of torsion springs include a pitch, and others do not. The pitch can help reduce friction building up within the coil structure. Torsion Springs are commonly used in automobile manufacturing, home appliances, outdoor power equipment, and electronic applications.
Compression springs are fabricated from wire. They are well-known as one of the most energy-efficient storage devices available. Depending on how they’re being used, they can store mechanical energy, resist force, or do both. Compression springs are used by Stanley Spring’s customers in medical devices and instruments, various electronics, and major appliances, among others.
Conical springs are a type of compression spring that are cone-shaped. One end of the conical spring has a larger diameter than the other end and the cone shape comes from the change in diameter that occurs when the spring spirals down from one end to the other. Conical springs are used in many applications and play an important role in many household appliances as well as cellphones and other specialty equipment.
Tapered springs are designed so that each active coil fits within the next, resulting in the tapered spring taking up less space. This is valuable because it allows them to be used in applications that wouldn’t usually have enough room for a regular cylindrical spring. A standard, helical compression spring that is not-tapered can buckle, but Stanley’s quality tapered springs provide additional stability where needed. Many Stanley Spring customers use tapered springs for electrical contacts like push buttons as well as battery contacts.
Variable Pitch Springs
Variable pitch springs differ from regular compression springs that are built to have a linear spring rate. Variable pitch springs have coils that are closer together in some areas and more widely spaced in other sections, and the spacing between the adjacent coils of wire is known as the pitch. Stanley produces variable pitch springs that have a progressively increasing or decreasing spring rate as the spring compresses. Variable pitch springs provide flexibility and will change based on the load balance, and they’re commonly used in the automotive industry. Motorcycles and race cars use variable pitch springs to provide better handling as well as shock absorbers.
Extension springs are helical wound coils made of metal designed to create tension. Extension springs are important parts in many products that Stanley’s customers produce, including washers, swings, trampolines, and other applications. Extension springs absorb and store energy as well as create a resistance to a pulling force. Extension Springs are attached at both ends to other components. When these components move apart, the extension spring will pull components together again.
There are typically two kinds of garters springs; compression and extension. A garter spring is a coiled steel spring that is connected at each end to create a circular shape, and is used in oil seals, shaft seals, belt-driven motors, and electrical connectors. Compression garter springs exert outward radial forces, while extension garter springs exert inward radial forces. The manufacturing process is not much different from the creation of regular coiled springs, with the addition of joining the ends together. Stanley produces garter springs that are designed to withstand pressure from all directions, making them extremely effective at handling changes in temperature, pressure, and volume.
A barrel spring is wider in the middle than on the ends, allowing for better stability because the pressure is distributed differently. The design of barrel springs prevents buckling and reduces space. There are many different design options available, making barrel springs a versatile spring that is beneficial in the agriculture, aerospace, marine, and automotive industries. They are also commonly used in furniture and toys.
As the name describes, these springs prevent kinks in products such as garden hoses and other consumer products. Specially designed anti-kink springs fit on the outside of hoses, tubes, and other pliable items to prevent bends or kinks. Stanley can produce your anti-kink springs in many different metal types, in a full range of sizes.-
