Tensile spring design parameters:
indicate the material diameter (
d)
, outer diameter (
D)
The presidents (
Ho)
The work world (
n)
, the location and shape of earring, load (
我p p 1 p 2……)
And the corresponding value (
H1H2……Hj）
If there is early tension, as shown in figure, is on the Po.
tensile spring nettley, generally speaking, there are threads of embedded, cross center TAB, retractor, more holes, shrink pores, rectangular convergent and teardrop-shaped convergent, convergent from spring body's length can be according to the specific circumstances.
More common is pegged to the extension spring, the 'hook' is a source of tension, its shape is circular cross section, easy fixed to the connected components.
extension spring characteristics test
the spring size including outside diameter, inside diameter, spring wire diameter, free length and tensile length.
In testing is often necessary to test the spring load and stress, this time to consider extension spring free length and the length, is the spring in the no load state and the length of the large tensile condition.
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.
