Common components for many businesses and applications are gas springs and closely related springs. Gas springs can be found in many applications, including overhead bins on airplanes and doors on armored vehicles or cargo vehicles.
Gas springs are an affordable choice for supporting moving objects or producing force due to their simple construction. How do gas springs work in practice? If you can understand the following key points, you will be able to improve the design of your motion controller system.
How Does Gas Spring Works?
Gas springs work in an analogous way to a mechanical compression spring. Instead of using elastic deformation to store potential energies, gas springs use gas cylinders to store it pneumatically. This is a fancy way to say that the energy is “moved through air pressure.” These springs are often used to produce nitrogen gas, but this is not always true.
The piston can glide freely out of the cylinder while the energy stored in the gas when it was compressed is released by forcing the piston into a cylinder. Like their mechanical counterparts, gas springs cannot regulate motion.
Gas springs have a shorter stroke which means that they move over a very short distance. However, once the stored energy has been released and the spring expands, the spring will exert its full force until it reaches its maximum stroke length. This could generate significant force depending on the application.
Gas springs produce a force that is nearly always the same. (An example: A gas spring’s force is almost always the same regardless of whether it is mechanical or wire.
When properly constructed, heavy-duty gas springs can generate a lot of force. They are often used in stamping dies because they can crush solid steel with sufficient power to form forms from other hard metals.
What Is The Difference Between Gas Struts And Gas Springs?
Gas struts and gas springs are often interchangeable terms. Sometimes, a gas strut can also be called a compression gas spring. There are some small differences that you should be aware of when designing with these devices. You can buy industrial gas struts from Selectlok.
Gas struts have a similar architecture to normal gas springs. However, they also feature pressure gas and a circuit which may reduce the force. The circuit allows you to change the speed of the spring’s movement. Gas struts can pull or push depending on the design.
You’ll see that many devices that you use every day include compression gas spring hinges. This includes the pistons in automobile hatchbacks as well as gas struts for lid applications. As you push the door down, you’ll feel resistance. The latch holds the compressed springs in position when the door is shut. When you unlock the door, the pressure builds up and the door will open again.
These devices are often equipped with circuits to prevent gas strut hinges from pressing so hard that they damage the door or injure the user.
