Extension spring for Commercial Use

Extension springs are widely used in automobiles, motorcycles, toys, amusement parks, athletic equipment and other commercial applications.  Extension spring materials for commercial applications are typically high carbon steel and stainless steel.

Commercial extension Springs can be produced by cost-effective CNC spring machines, according to customers’ specifications.  Commercial extension spring treatment can include; powder coating, nickel plating, chrome plating, black oxide, passivation, rust-preventative oil and zinc plating, which are usually clear or yellow.  Extension spring wire diameters can be anywhere from .005” up to .625” in cold wound.

Commercial extension springs are typically attached with closed eyes or open hooks.

Extension Spring Geometry

Extension springs are typically manufactured with an initial tension. Extension spring initial tension is the force required to break apart the adjacent coils. This fabrication method allows consistent free length.
Since the extension spring initial tension is not zero, the spring rate is not truly linear when measured from the unloaded position. However once the initial tension is overcome, the extension spring does behave linearly.

Extension Spring Shear Stress

Since
extension springs

in their resting state, they also have a shear stress in their coils while at rest. The maximum shear stress, in its free position occurs on the inner face of the coils.

After the initial tension is overcome, the extension spring can be analyzed as a compression spring with a negative force. The maximum shear stress in the extension spring increases with the load.

Extension Spring End Stress

When considering a regular extension spring hook, the geometry of the hook often causes stress concentration which leads to failure.

Extension Spring Safety

With an extension spring, there is no such safety geometry, as with a compression spring, since the extension spring is in tension. For this and other reasons, extension spring maximum working stresses are typically limited to three fourths of those for compression springs of similar geometry and spring material.

A compression springs are coil springs storing energy when they are closed by a force. Compression springs are designed to operate with a compression load, so the compression spring gets shorter as load is applied to the spring. Stored energy in the spring is brought back to original state after force is removed to lengthen the spring and push against the object that compressed it.

 

Mechanical springs are of many forms out of which most common spring is compression spring. Compression springs can further be categorized as Conical Springs, barrel springs and hour glass spring to name few.

 

From the simple writing pen on car, compression springs have many uses, The function of each small or big machine is determines by the compression spring. For example, how would a ride in that car feel if there were no compression springs to support the shock absorbers?

 

A compression spring has elasticity born in the spring wire  used to store mechanical energy. Compression springs are usually made out of spring-tempered steel or from age-hardened spring material. Small compression springs can be wound from pre-tempered material, larger compression springs are made from annealed steel and hardened after winding. Some non-ferrous spring materials including; phosphor bronze, titanium, Inconel ™ Elgiloy ™ are used for compression springs requiring corrosion resistance.
