Different Types Of Compression Springs
A spring is an elastic object used to store mechanical energy
. Springs are usually made out of hardened steel. Small springs can be wound from pre-hardened stock, while larger ones are made from annealed steel and hardened after fabrication. Some non-ferrous metals are also used including phosphor bronze and titanium for parts requiring corrosion resistance and beryllium copper for springs carrying electrical current (because of its low electrical resistance).The rate of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve. Depending on the design and required operating environment, any material can be used to construct a spring, so long the material has the required combination of rigidity and elasticity: technically, a wooden bow is a form of spring.
Compression springs are springs that become smaller when pressure is applied to them. Helical compression springs are the most common shape, but in certain special applications other compression spring types will be used. Oil-tempered springs and hand drawn stainless steel wire are the most common material types for springs. Coiling machines coil the springs into different diameters and shapes. A compression spring serves the opposite function of an extension spring. An extension spring holds two items together, while a compression spring keeps two things apart.
Basically there are many types of compression springs available in the market. Some of its types include the following:
Conical Springs: These compression springs are generally in the shape of a cone and are thus called conical springs. These springs are used to fit in designs where the helical or coil spring does not fit.
Barrel Springs: Barrel compression springs are barrel-shaped compression springs.
Hour Glass Springs:
Hourglass spring designs have circular ends in which the diameter is wider than its center. This gives it the distinct hourglass shape..
Variable Pitch Springs:
A variable pitch spring has different levels of compression. One end will have a wider frequency than the other end, or it will look more compressed on one side than the other.
