Tension at the beginning of the
spring tension: initial tension equal to that required to pull against each other in the spring and circle, 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
Spring constant tensile length X
tensile spring associated standards:
GB/T_1239 [

2009 _ _ cold roll of cylindrical helical spring technology conditions, part 1: tension spring;
GB / T2087 -
2001 cylindrical spiral tensile spring size and parameters: GB/T 2008 -
1997, etc.
abstract: closely around the circle, so that it can force and stretched, each side around a loop (
循环)
。
the following necessary for a stretch of the spring data:
1, free length, total length, long full circle, since the length of hook circles;
2, control the diameter, outer diameter, inner diameter, the inside diameter of casing;
3, steel wire size wire diameter;
4, materials (
Species, grade)
；
5, laps: the total number of turns and right-handed or left-handed;
6, the end of the form;
7, within the hook load;
8, load rate, deflection, every inch of pounds;
9, tensile length.
Tensile spring (
Also called torsion spring, tension spring)
Is under axial tension spring, tension spring are generally made of material with circular cross section.
When not under load, tensile spring between the circle and circle are generally no clearance and tight.
