The tension spring acts as a buffer. Extension spring is an industrial accessory that has functions such as support, buffering, braking, height adjustment, angle adjustment, etc. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, etc. Extension spring is a type of spiral spring that can withstand axial tension. Tension springs are generally made of circular cross-section materials. Under no-load conditions, the tension spring between rings is generally taut and there is no gap.
Characteristics of tension spring
Use multiple different terminal devices or ‘hooks’ to stretch the tension source of the spring. The function of an elastic spring is opposite to that of a compression spring. Compression springs act in the opposite direction when compressed, while tension springs act in the opposite direction when stretched or tightened. When the two ends of the tension spring are separated, the spring attempts to pull them back together.
Like a compression spring, an elastic spring absorbs and stores energy. But unlike compression springs, most tension springs have a certain degree of tension even without any load. This initial tension determines how tightly the spring is wound without any load.
