Bellows Type Air Spring
Bellows air springs have one, two or three convolutions in the
flexible member. There are two styles of bellows; crimped design .
With the crimped design, the end retainers are permanently attached
by mechanically crimping the retainer around the built-in bead wire
of the flexible member.
Don't of air spring
1. Do not exceed 200 psi internal pressure in compression, or in
other condition.
2. Do not permit the air spring to be compressed below its
compressed height with no bumper in any application.
3. Do not put air spring in torsion. To do so may cause the air
spring assembly to fail
4. Do not exceed the maximum extended height shown for isolators
under any conditions. To do so may cause structural damage to the
assembly. Travel should be limited to the actuator height limit for
optimum life.
5. Do not exceed the 100 psi maximum inflation pressure.
Application
In a vibration isolation application where the mounted mass is the
source of the forced vibration, the amplitude of the vibration is
dependent upon the forced freqency and the ratio of unbalanced mass
in motion to the total mounted mass. The greater this ratio is, the
greater will be the amplitude of vibration.
Where amplitudes are larger than desired, they can be reduced by
adding damping through the use of shock absorbers. Another approach
to reducing the amplitude is to add weight (an inertial base) to
the mounted mass, thus reducing the ratio of the unbalanced mass to
the mounted mass.
