Tension springs, also known as extension springs, are coil springs, normally tightly-wound, that are loaded in tension. Tension springs usually have hooks or loops which are attached to components. If these components are moved or pulled apart, the spring opposes this extension, exerting a force to bring them together.
Tension springs have a wide range of uses and are found in many applications, such as switches, levers, braking systems, trampolines, tools, garage doors. They are used in a wide range of industries from rail and agriculture to oil, gas and aerospace engineering.
Tension Spring Parameters
The following parameters are important in establishing the correct design of tension springs:
The size of any hole the spring works in
The loads/forces required and the lengths at which they are required
The maximum working deflection required
The frequency of operation
The operating environment. This will determine the choice of material and/or the choice of any finish for corrosion protection
How and where the spring is to be fitted. This will determine type of loops or ends required. There are many different forms of tension spring end
