DESCRIPTION
The usefulness of air springs or actuators didn’t go unnoticed in
the industrial machine industry, and it was clear they could
provide unique solutions for various applications. Air actuators
have seen duty as shock absorbers, linear actuators, vibration
isolators, and tensioners, to name a few examples. They can be used
to absorb shock in material handling applications, such as a saw
mill, when logs are dropped onto processing stations. Air springs
make some of the best vibration isolators on the market, such as
would be used on a vibrating hopper or commercial laundry machine.
In summation, air springs are a high force, low cost actuator that
can operate in a linear fashion or at an angle. They can be stacked
to provide longer strokes or greater angular rotation.
Air springs contain a column of air in an elastomeric bellow or
sleeve to provide suspension, isolation, or actuation. Commonly
found in vehicle suspension systems, occasionally in conjunction
with a coil spring, they are also used to insulate vibration in
machinery and as linear or angular actuators.
Air springs are employed through the use of an air compressor which
fills and empties the pliable air bladder. The load is not
distributed to the rubber liner, which only serves to contain the
gas; the weight is attached to a piston or bead plate, which is
directly supported by the air with very little deflection. A
self-leveling mechanism is common to keep the air spring's load
stable, and occasionally a separate coil spring is incorporated
into the design. Also available are electronic air spring systems
that can monitor air pressure, filter compressor air (preventing
damage to the rubber bellows), and a lock to keep air inside of the
spring in case of compressor or air line failure.
