Features:
a number of different terminal device or a 'hook' is used to ensure tensile
spring source of tension.
Contrary to the principle of
compression spring tension spring.
Compression spring reverse effect at the time of compression and tension spring, a reverse effect at the time of stretching or open.
When tensile spring open on both ends, spring will be trying to bring them back to together.
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.
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
