Top 9 Things about Springs You Didn't Know



(TORONTO – AgoraMedia.ca Wire) – A spring is a part possessing elastic properties that is intended for accumulation or absorption of energy of a mechanical origin.
The variety of springs is large.  This article lists some variants of the species used. As a rule, these are mainly cylindrical springs with spring rings, which take a longitudinal-axial load on compression or tension. Springs working on compression require guide mandrels or rods to specify the working direction, while springs that work by stretching require brackets to fix them.

  1. Conical helical springs have a higher resistance to lateral bending during compression without mandrel, in contrast to cylindrical helical springs. They are used usually in those cases where it is impossible to apply the guide rod or sleeve and when the height of the spring in the compressed state should be minimal. Springs of this type have the turns that enter one into the other.
  2. Springs of torsion have a cylindrical winding. They work on twisting. They are used in case of need to transfer the axle load. As a rule, fixation elements are used for their normal work.
  3. Flat spiral springs are widely used in the designs of various mechanisms and devices, mainly as energy accumulators. They are used, for example, in mechanical watches, alarm clocks, in some engines of clockwork toys. The starting material from which the springs are made is special elastic steel and non-ferrous alloys capable of returning to its original form under acceptable design loads during compression or stretching.
  4. Production of steel spring wire is a very laborious process and is carried out by pulling on drawing mills with thermal processing and etching at intermediate stages of forming the required cross-section. Very serious requirements are imposed on the surface of the wire.
  5. If the springs are wound from a wire with a small cross section, they are allowed not to be subjected to subsequent heat treatment, but to use a finished wire, whereas power springs subjected to considerable loads are made of annealed steel with subsequent hardening even after molding.
  6. The most dangerous type of quenching, in which very sharp cooling occurs, is quenching in water. Since spring steels have a low thermal conductivity, excessively sharp cooling can lead to the appearance of hardening cracks due to the action of large internal stresses. Quenching by this method is used in rare cases. The most preferred types of quenching media for spring steels are oil or air.
  7. The winding is done on special machines that are able to produce springs, both with left and right winding, and if you want to bend the outer threads to give the desired form of spring engagement, this happens automatically and at high speed. Automatic machines can wind both small springs, and large, depending on the model, with the possibility of thermal impact on the material being processed.
  8. Compression springs are widely used in various designs almost in all industries, from ballpoint pens to powerful motorcycles.
