COMPRESSION
SPRINGS |
| |
By far the most commonly used type of spring. In its simplest
form it is possibly the most economic spring to use by virtue of
the lower material content and the speed at which they can be
produced versus the amount of energy it can store.
Compression springs are made from round, square, rectangular,
trapezoidal, oval or even special shaped wire cross sections but round wire is by far the most common and easier to work
with. The reasons for choosing the other material cross
sections is varied but it is usually based on either strength for
volume or dynamic considerations of the application.
The shape of the compression spring is mostly parallel sided
i.e. of nominally constant diameter but is often seen as a
conical shape and sometimes barrel or waisted (hourglass) shape.
These alternative shapes are often again related to strength for
volume but you are penalised for loss of a nominally linear
spring rate.
Using compression springs nested together i.e. one inside the
other is not uncommon, and this would be to achieve strength for
volume or dynamic effects.
Most often compression springs have closed ends for stability
and these are very often ground flat to square for that benefit.
It does however increase the cost and is to be avoided whenever
possible and would generally be considered un-necessary on wires
less than 0.5mm diameter.
At Kato-Entex we produce a very broad range of compression
springs in terms of both size and complexity of shape. We can
coil them from wires as small as 0.1mm diameter up to 14.0mm
diameter. If you need micro compression springs these are
capable of being produced within Advanex Group in wire diameters
as small as 15 microns and we would be pleased to hear of your
interest in these high technology components.
