How do you calculate gas springs?
FORCE = (W x Y) / (Z x N) Y = Distance from fixed mounting point to center of the object (mm). Z = Distance from hinge point to moving mounting point (mm). N = Number of springs.
How do I choose a gas strut?
In general the length to choose for gas struts is about 55% of the height of the door you are trying to keep open. So if you have a door that is 1000mm in height a 550mm long gas strut would be about right. In simple terms we are talking half the door height plus a bit when determining optimal gas strut length.
How does gas spring work?
Gas springs are charged with nitrogen gas to a high pressure and the gas is sealed inside the spring. The gas pressure acts on the piston rod or the piston (depending on design) of the spring and provides a resistant force.
What is a gas traction spring?
A unit that offers a controlled pulling force without the use of external energy. A traction gas spring produces a controlled pulling force for use in a number of assemblies. A traction gas spring often provides help in raising something, where the item is helped back into place and kept in its end position.
What is gas spring extension force?
Gas springs consist of a precision rod attached to a piston, moving within a sealed cylinder containing pressurized nitrogen gas and oil. Their force (F) is equal to the pressure differential (P) between internal and external (environment) pressures, acting on the cross-sectional area of the rod (A).
How do you measure gas struts?
Co-Mac’s gas strut length is measured from the centre of the ball joint at each end. If you want to replace an existing gas strut, measure the length of your strut from the centre of each ball joint. If your gas strut does not have ball joints, measure the length of the gas strut with no end attachments.
What gas is in a gas spring?
Nitrogen gas and oil are utilized for providing compressible and damping (motion control) mediums. Gas springs can be configured to meet a wide range of requirements. Gas springs consist of a precision rod attached to a piston, moving within a sealed cylinder containing pressurized nitrogen gas and oil.
What is a traction gas strut?
Traction gas struts, despite their name, work in the opposite direction to standard gas struts. Rather than exerting an extension (pushing force), they pull applications together and are often used in return assist motions. For example, one common use is to close a lid, flap or ramp.
Do gas struts push or pull?
Gas StrutsLearn More Gas pressure internal to the strut provides a push or pull force depending on configuration, but also contains a dampening circuit typically to control the speed of motion through one or both directions of travel.
How to make a gas spring calculation for your application?
Determine the total weight of the application. Determine the position of the pivot point. Choose how many gas springs you want to use. Check the angle of the application. The detailed explanation below can help you successfully make a gas spring calculation for your application. In step 1 please enter the following information about the cover:
Can I have the current gas spring series included in re-calculation?
If you would like to have the current gas spring series included in the re-calculation, please choose a different fitting. The re-calculation will consider only gas springs which support your configured fittings and brackets. The overview shows the products you configured with the sizing tool. After submitting your data we will contact you shortly.
What is the D measure of a gas spring?
The D measure is the vertical distance between the pivot point and the point of attachment of the gas spring to the “fixed world”. Distance to the center of the eye or ball.
How to identify the fixing points of a gas spring?
The first step when identifying the fixing points is to measure the panel. This example shows a panel in its closed position. Please make a note of Measurement A _________________ Measurement B _________________ Correct fixing points are most important for an effectively working gas spring.
