Formula:
spring constant: k said, when the spring is stretched, each additional load (1 mm distance
kgf /毫米)
spring constant formula (
Unit: KGF/mm)
:k = (
G*d4)
/ (
8*Dm3*Nc)
G: module of rigidity of wire;
D: wire diameter;
Dm: - pitch diameter = diameter
Wire diameter;
Nc: laps = total number of laps - effectively

as compression spring, tension spring is also absorb and store energy.
But I don't like the compression spring most of the tensile spring usually under a certain degree of tension, even in the absence of any load.
This determines the initial tension in the absence of any load, tensile spring coiling of the close degree.
Application:
tension springs and spiral extension spring, generally for pitch, such as cross section is round more, they can be used in many occasions, such as production assembly, experiment, research and development, maintenance, etc.
Tension spring occupies an important position in the global market, widely used in national defense, Marine, computer, electronic, automotive, mold, medical, biological, chemical, aerospace, railway, nuclear power, wind power, thermal power, engineering machinery, mining machinery, construction machinery, elevator, etc.
pull at the beginning of the spring tension: the tension equal to open to each other at the beginning of spring and circle the required force, tension in the early spring coiling occurs after forming.
Torsion spring, because of wire material, wire diameter, spring index, electrostatic, lubricating oil, heat treatment, electroplating, make each tensile spring initial produce uneven phenomenon.
The torsion spring, so the installation specification shall be of pretension to slightly apart some distance between each and circle.
At this time the force needed to become the initial tension.
initial tension = P -
K X l = large load
The spring constant tensile length X
