What to consider when choosing the right springs for your design
The following are the most common spring types available on the market today and examples of uses for these.
Compression Springs are used to create a pressure against two surfaces or objects. They are being used in smaller objects such as latches and vents, but also for very large solutions such as vibration dampers on road bridges. The material used is often alloyed steel or stainless steel. The compression springs can be wounded with either hot or cold materials.
The actual wire used for winding the compression spring to a spiral, is available in dimensions smaller than a hair and up to 6.5 cm. The windings diameter and number of turns are also available in different sizes depending on the needs and requirements in the spring.
Tension springs are used to pull together two surfaces or objects with a certain force. The force of the spring is different depending on how tightly the thread is winded, either sparse or dense. A tension spring usually has some form of end fittings, in example loops or hooks to attach the two objects to be drawn together. Tension springs are probably found in objects such as door locks, push chairs and office lights.
Torsion springs are used to merge or split two surfaces or objects to a certain angle. Torsion springs can be left or right winded and are available in both with single and double function. The force of a torsion spring is lower the further out in the spring one is. We find torsion springs in for example shutters, doors, clothespins or large items such as office chairs. The size of wire used for torsion springs are usually between 0.1 mm to 5 cm and most metals can be used for manufacturing.
Clock springs - The clock spring is a type of torsion spring. It has more turns and is made from flat wires instead of round wires. Clock springs rotates around the object's axis and to give its force to the other object through the outermost edge of the spring.
An advantage of the clock spring is that it’s free from friction between the coils when assembled in the correct way.
Clock springs are in being used in watches, as height adjusters on the steering column of trucks and in power switches. Clock springs are mostly manufactured in stainless steel.
Motor springs - Just like the clock spring, the motor spring is a type of torsion spring with more turns and flat wires instead of round wires. A motor spring is sensitive to friction and must be lubricated at the assembly. The sensitivity is caused because of very tight turns, allowing the friction to occur. The motor springs are each normally about 10 - 20 turns, making the circular motion to be a maximum of 20 turns. If you need more torque than what one motor spring can do, just use a number of motor springs next to each other. The motor springs are often represented in the electric power industry in for example distribution plants, usually manufactured in stainless steel.
Constant force springs also belongs to the category torsion spring as it’s turning about its own axis. However, the constant force spring is used to power the linear motion. Constant force springs can be mounted both single and double, depending on the power needs. A constant force spring is made of a strip of stainless material and is used for example in goods dispensers in stores where the goods automatically move forward because of the pressure after a product is being removed.
Die springs are fairly similar to compression springs in its design and function, and are mainly used in tools. A die spring has rectangular threads instead of the more used round threads. Die springs are being used in tools such as pressure tools and valves. They are used in objects where there is limited space for the spring to work. Depending on how tightly the threads are, the die springs ability to withstand stress and pressure vary.
Gas springs are used frequently in need of a soft opening/closing of for example a door or over-hung doors. There are gas springs called lockable gas springs and these are used where there is a requirement for stepless adjustment with locking. They are used for, among other things, office chairs, and patient equipment where the requirement for smooth motion is high. A gas spring is filled with nitrogen gas and is cylindrical. It is categorized by the length, force, motion and reduced motion. To make it possible for the gas spring to be attached to the two items needed to be adjusted, threads or loops of any kind are being used.
Leaf springs are used to lock something. For example, there are leaf springs in the hatch latch on the stove in the kitchen. Leaf springs are sometimes also called clips which are being used in paintings to keep the cover into place against the frame. The production of leaf springs is made by laser cutting or stamping manually or automatically. You can choose the thickness of the material, design and stamping completely depending on the requirements and needs. The thickness of the material is around 0.1 - 7 mm.
Disc springs - when you are in need of very high force on the spring but still must adhere to a short suspension travel, a disc spring might be the right type of spring. Stack multiple disc springs on top of each other, even they are of different thickness, if the need exists. Disc springs are found in for example packaging machines which require a higher pressure and trucks.
Coil springs is actually the collective name for all spring types with a coiled solution. Among the above, all of them are coil springs except gas springs, leaf springs and disc springs.
Materials and manufacture of springs are constantly evolving and new technologies emerge to meet the growing demands placed on the springs, both in terms of environmental and product performance.
The process of developing a spring starts with an analysis of the application and the desired function. Based on the outcome, materials and spring design are chosen and the spring is designed so that the desired performance is achieved. In addition to this, force or torques at a suitable suspension is important factors which can be calculated with good accuracy. Before starting a mass production of springs, it is a good idea to do a prototype of the spring which can be tested and approved in its proper environment.
