The value given result of our experience. Les données indiquées renvoient à des valeurs concrètes, obtenues à 4 alternances.

For knowing and approch the real curve Force/Deflection each spring should be th subject to complete cycle Load and Unload.

2 Spring Module d'élasticité E ( N / ² ) 1 70 Frequency of stockes The number of races/minute in dynamic continuous use must be always taken into account. An increase of the speed corresponds to a decrease of the % of compress i o n. By staying below the limit value, the longevity increases because of the low heating (Hysteresis). Temperature resistance The operating range is C to + C For short term C to + 1 C are Possible. Any material subjected to a deformation and an internal friction warms up. The characteristics of the spring are determined by the module of elasticity according to the temperature and geometrical shape The elastic propertie and is E/modul depend of temperature see diagram Tolerances U 90 Température ( C ) U Dimensional Norm DIN ISO 32 1 M3 Temperature Reference + C.

Their behavior power / running is in compliance with the laws of well known elasticity of the traditional springs. The directives of assembly below must be respected to reach a maximum use. Implementation l d8 do Elastomers are incompressible. Their deformationunder load is translated by an inflation. It means that the percentage of inflation is equal to the percentage of compression. It is thus essential to checkthe curve of inflation to determine and define locations and spaces of safety. S Surfaces of support l L2 dg Do DA The faces of support must be smooth. They can be flat, concave or convex. In this last case the diameter of the face of support owes. If mounted in a recess, the clearence DA must be adapted to the bulge factor (see diagram) Hauteur du ressort () impossible possible 1 ressort 2 ressorts 3-4 ressorts Diamètre du ressort Do () Contact surface Should be smooth Rz 25 to Rz in accordance to DIN ISO They can be flat, eleveted, or in a recess. The diameter Do must at least equal of the spring diameter. Guidance spring To guide, center, avoid the frictions and the risk of buckling it's better to use guide bolt. These are essential in case of stacking. Stacking We obtain a greater strocke we need stacking springs. They will be guided to increase their longevity and separated from each other by slices washers to preserve their autonomy of deformation. Under the same power, the strocke add up. Greasing guide bolt axis is required. 11
