Working principle of the tension spring

Hereinafter referred to as tensile spring, also called extension spring, is under axial tension spring, tension spring are generally made of raw materials production with circular cross section. When not under load, tension spring between the circle and circle generally all is no clearance and tight. There is a screw tension spring, generally for pitch, such as cross section is round more, they can be used to many occasions, such as production, experiment, product development, manufacturing and assembly of the maintenance.





many different terminal unit or 'hook' is used to ensure the tension spring source of tension. Tension spring contrary to the principle of compression spring. Compression spring at the time that the pressure in a reverse effect, while the tension spring stretched or opened when the reverse effect.


when open on both ends of the tension spring, spring will be trying to pull them back together. Like a compression spring, tension spring are absorb and store energy. But unlike compression spring is that most of the tension spring is generally under must level of tension, even in the absence of any load condition. The initial tension of decisions in a no load condition, close horizontal tension spring coiling.
