Tension
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.
tensile spring associated standards:
GB/T_1239 [
1]
。
1 -
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.
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.
With technology speeding up in lighting speed, have created quite a name for itself amidst leaf spring hardware and it happens to have a lot of benefits as well.
Dongguan Yongqiang spring hardware Co.,Ltd. endeavors to be valued as an industry leader in client satisfaction, sales growth, product performance, financial strength and profitability.
Dongguan Yongqiang spring hardware Co.,Ltd. has never conceded on the quality and the services of the products which provided to the customer.
The rising leaf spring hardware consciousness observed worldwide are expected to be key factors driving the demand for leaf spring hardware News.
