They are slices of constant thickness and tronconique shape. They allow, according to needs, to obtain springs at the rates of fléxibilité increasing, invalid, lessening or combined.
These springs are distinguished by their qualities of power, relaxation and safety. The mechanical characteristics remain constant, even after several thousand flexions.
Slices springs are realized steel fine spring, XC75 and 50 CV 4, or in special alloy, cupro-bérylium, stainless steel.
Characteristics and use :
(Example of pile using slices identical resorts)
  1. A slice
  2. Two emboitées slices, the unitarian load(responsibility) increases twofold (3 % / slices added due to the friction).
  3. Two slices were set, the arrow increases twofold for the same unitarian load(responsibility).
  4. Two opposite packages of two fitted slices, the unitarian load(responsibility) increases twofold (+ friction), the arrow were twice the one of a slice.
Slices springs(competences) are manufactured on beams(shelves) from the thickness 1 and totally manufactured from the thickness 4.
In this last case, they contain dishes on the faces of support, subordinate and superior.
As a result of the existence of these facets, the nominal thickness e becomes reduced thicknesse'.
Type

A : NF Standart E 25-104 (h/e ~0.4)
B : NF Standart E 25-104 (h/e ~0.75)
C : Very graded characteristic (h/e >=1.1)
N : Manufacturing standart according to the criteria of NF E 25-104.
Reliability

The reliability is determined by the amplitude of work situated between :
* The load(responsibility) max of use (< = PL indicated on abacus below)
* The load(responsibility) min of use (precompression > = 0,10 - 0,15h).

For any specific problem bound(connected) to the use of slices springs and in particular the life expectancy, to consult making it.
Mechanical characteristics

The values P1-P2 - P3-P4 allows to establish quickly the characteristic curve of the slice stands out(goes out again,rereleases).
