All About Compression Springs

Posted by Admin on July, 23, 2012

One of the various types of springs is the Compression Spring. The Compression Springs are also available in the form of the Heavy Duty Compression Springs. Talking about the Compression Springs, they are specifically designed for opposing compression of any kind along the axis of the wind. The Compression Springs oppose the linear compression forces and it would be fair to state that the Compression Springs are one of the best energy storage devices in the present times.


Key Parameters Of Compression Springs
Some of the key parameters of the Compression Springs are as follows:

  • Spring diameter – It is of three types
    Outside diameter (specified if Compression Springs function in a cavity.)
    Inside diameter (specified if Compression Springs function over a rod or shaft.)
    Mean diameter (used in stress and deflection calculations.)
  • Wire diameter – Used for calculating spring index.
  • Spring index – Ratio of the mean coil diameter to the wire diameter. Preferably between 4 and 12.
  • Free length – Overall length of the unloaded Compression Springs.
  • Solid height – The height of the Compression Spring with all the coils closed.
  • Number of coils – Number of coils in the Compression Spring that free to deflect under load.
  • Pitch – Distance between the wire centers and the adjacent active coils of the Compression Springs.
  • Spring rate - The change in load of the Compression Spring per unit of deflection. This is generally expressed in terms of pounds per inch.

Compression Springs can be left or right hand coiled. For the determination of the direction of the Compression Springs, it should be held with its axis on a horizontal plane. If the Compression Spring is simulated by the index finger of the left hand, then it is a left hand coiled Compression Spring. And if the same thing happens with the index finger of the right hand, then the Compression Spring is a right hand coiled Compression Spring.


There are numerous types of end treatment for the Compression Springs. Added to that, there are various other considerable factors for the Compression Springs such as squareness of spring ends, buckling, stress operating types, deflection, and parallelism. The Compression Springs are one of the major industrial products of the modern times and are used in a large number of industries and other components for ensuring effective and hassle-free operations.
