About Vibration Absorbers
Vibration absorbers consist of elastomeric pads, mounts,
bushings and bumpers that protect industrial equipment and machinery
components from the harmful and inefficient effects of vibration. Vibration
consists of a series of oscillations that move at a cyclic pace at varying
frequencies. Vibration may come from an external source or from an internal
source within the equipment. Internal vibration is often caused by an
imbalance between equipment components. Vibration absorbers isolate the
equipment to which they are attached, preventing the spread of vibrations
throughout the equipment components.
Some shock and vibration absorbers contain a hydraulic element that works
as a comprehensive dampening system and returns the mechanism back to
an unengaged position. Other vibration absorbers are nothing more than
rubber bumpers or engine mounts that are enclosed within the machinery
in need of vibration and shock isolation. The vibration created by neighboring
machines along a manufacturing process requires the absorption of even
the most minute movements. Unbridled vibration can lead to a variety
of problems, including equipment malfunction and inaccurate product manufacturing.
Because of the wide range of shock absorbers used in industrial settings
and components, the vibration absorber manufacturers work along with
customers to meet specific demands. An example of product development
related to vibration absorbers is the harness protection line of products
that was developed for Bacou-Dalloz and their product line of shock absorbers,
harnesses, and vibration absorbers. Custom molded and designed parts
and services are often necessary to meet customer needs, and most of
the providers of shock and vibration absorbers and equipment have these
capabilities. Often working alongside their customers, vibration absorber
manufacturers facilitate this custom process with a consultation and
diagnosis period, which involves preliminary testing of determinative
factors, such as the lowest disturbing frequency for a part or component
and the percentage of vibration reduction desired.
Vibration isolators provide vibration control to numerous machines and
equipment parts in almost every industry. Vibration isolating systems
are found in engines, conveyors, vehicles, motors, heaters, air conditioners,
ventilation systems, appliances and many other items. Vibration isolating
systems remain an effective way of combating equipment defects. Vibration
isolators are common because they are usually cost-effective, easy to
install and often have a long life. When considering vibration absorber
manufacturers, consider the weight and size of the equipment, the type
of elastomer best suited for the application, other forces such as shock
and noise that may affect the equipment, and substances like chemicals
and oils to which the isolator may be subjected.

Types of Vibration Absorbers
- offer
a favorable stroke-to-compressed-height ratio, when compared to air
cylinders, and can accept a wide variety of actuation media, such as
air, water, nitrogen or anti-freeze for use in a variety of vibration
isolation applications.
- are placed between moving parts to absorb vibration.
-
are driven by circular motion. The cam follower traces the surface of
the cam transmitting its motion to the required mechanism.
- are
absorption devices that use fluid to enact resistance. Once downward
force is no longer being applied, the plunger-like device remains in
position. Dashpots are used normally in small devices, such as instrumentation
and precision manufacturing machinery.
-
are vibration isolators placed between an engine and the structure that
supports the engine, in order to reduce the effects of vibration, noise
and shock encountered during engine operation.
-
achieve attenuation of both shock and vibration and are made entirely
of non-corrosive materials. Helical isolators are most commonly used
for vibration and shock absorption in such industrial and commercial
machinery as compressors, hammers, printing machines and other applications
in which shock isolation is important to the effective and efficient
running of the apparatus.
-
protect machines from vibrations emanating from within the equipment
itself, as well as from other pieces of equipment. Machinery mounts
are used on compressors, screw machines, pumps and generators.
-
are commonly used in the automotive/trucking industry to protect vehicles
and trailers through vibration and shock absorption.
- are rubber components that isolate the vibration from moving parts.
-
are vibration dampeners often placed between industrial equipment and
the surface upon which the equipment rests. Rubber pads may have a ribbed
pattern to prevent slippage.
- use various methods to dampen vibrations caused by sudden motion and mechanical shocks.
- are rubber mounts used to protect a variety of industrial
items, including engines, machinery and equipment components. Vibration
mounts effectively reduce or eliminate oscillation.
- are used to protect equipment by keeping the vibration of a component from spreading to the entire machine or work environment.
-
consist of a metal cable configured in sets of strands. Wire rope isolators
are used in applications in which exposure to chemicals, oils and high
or low temperatures is common.
