COMPRESSION SPRING TECHNICAL DRAWING

  By means of compression springs compression energy storage, load (force) is used for the purpose of resisting the forces of supply or pressure. Sanyide the most common type of round wire, closed ends of the wound, is one of the two sides parallel to each other. Solve the problem of loss of height, block height, and reduce excessive vibration or non-linear load (force) to get the features, latest technology, constantly renewed pressure springs with spring winding machines, high-quality, conical, barrel or cask types of compression spring is producing the opposite. Print Bows, the average diameter of the wire diameter, spring rate to be between 5 and 11 of the spring index is preferred. Sagittarius makes the self-developed bow design programs to its customers with custom designs.

Springs store energy elements.
Compression Bows, provided that material to stay in the elastic region, a force F acting in line with the axis of the publication so that they can be compressed and stored energy back then.
Compression springs Terminology :
d : Spring Material Wire Diameter    (mm)
Di :  İnner diameter of Spring   (mm)
Dm = Di + d  :   The average diameter spring   (mm)
Dd = Di + 2*d   :   The outer diameter of Spring   (mm)
p : Pitch of spring  (mm)
a= Winding angle of Spring   :  alpha (degrees)
a = Arctan ( p / p*Dm)          ( p :  Number of pi=  3.1416 )
w = Dm / d  :   Yay indeksi

( Usually  4 = <  w  < = 20  recommended.)
a 12-degree angle is smaller / tighter coiled springs that, the force F acting on pedestrian publishing material the wire, only Torsion (Mbur) Shear stress of it so that they (Kbur) and direct cutting stress (KKES) generates accepted.

    Mbur = F * Dm / 2        (Nmm)         

3                         2
Kbur = Mbur / ( p* d  / 16 )      (N/mm )
2                    2
Kkes = F / (p* d / 4)           (N/mm )
Max. Shear stress (K) accounts can be selected between the two Operation.
