- A spring is a device that changes
its shape in response to an external force, returning to its original
shape when the force is removed.
- The energy expended in deforming
the spring is stored in it and can be recovered when the spring returns
to its original shape.
- Springs are usually made out of
hardened steel.
- Small springs can be wound from
pre-hardened stock, while larger ones are made from annealed steel and
hardened after fabrication.
- Springs are classified according
some of its properties.
- Depending on load it can
classifies as: Tension/Extension spring, Compression spring, Torsional
spring.
- In tension/extension and
compression there is axial load. On the other hand in the torsional
spring there is torsional force.
- Most springs (not stretched or
compressed beyond the elastic limit) obey Hooke's law, which states that
the force with which the spring pushes back is linearly proportional to
the distance from its equilibrium length.
- Steel alloys are the most commonly
used spring materials. The most popular alloys include high-carbon (such
as the music wire used for guitar strings), oil-tempered low-carbon,
chrome silicon, chrome vanadium, and stainless steel.
- Other metals that are sometimes
used to make springs are beryllium copper alloy, phosphor bronze, and
titanium.
- Rubber or urethane may be used for
cylindrical, non-coil springs. Ceramic material has been developed for
coiled springs in very high-temperature environments.
- Manufacturing process of
steel-alloy, coiled springs include Coiling, hardening, and
finishing.
- A Company in California uses
HELI-CAL Flexure technology to produce high performance, machined
springs in a way that takes much of the guesswork out of the design and
manufacturing processes.
- The gas springs of the LIFT-O-MAT
and BLOC-O-LIFT series from STABILUS provide comfortable and safe
lifting, lowering, and positioning of flaps, lids, and hoods.
- STABILUS has also developed highly
compact gas spring types for trailer applications, they are easy to
install and follow the rules of space optimization.
- The gas springs of are also used
for the manufacture of highly functional and ergonomic vehicle and
airplane seats.
