The helical compression spring is a helical spring wherein the coils are apart from each other and as the name suggests, the spring is designed to withstand the axial compressive load.
When compressive forces act on it, the spring coils compress and come close to each other. If the load is removed, the spring returns back to its original shape.
Applications of helical compression spring include shock absorbers in automobiles, suspension in cycles, applying pressure in a clutch of an automobile, in brakes of automobiles, in spring balances for measurement of force, toys, etc.
Helical torsion spring
As the name suggests, in the helical torsion spring the force is applied tangentially to the axis and the spring is subjected to twisting by the forces acting on it.
When the spring is subjected to twisting, it exerts torque in the opposite direction and is proportional to the amount angle it is being twisted.
Applications of Helical torsion spring include as simple as the spring in hair clips, mouse traps, hand gripper in gyms, robotics, and many more
Open coil Helical spring
An open coil helical spring is a spring that has a helix angle greater than 10 degrees. There is a considerable amount of gap between two adjacent coils of the spring.
The following are the advantages of helical springs
Helical springs are highly reliable.
They have a constant spring rate.
Helical springs possess good durability.
Helical springs are available in a wide range according to the application.
FAQ on Helical springs
What is a helical compression spring?
The helical compression spring is a helical spring designed to withstand the axial compressive load. In it, the coils are apart from each other and when the load is applied, the spring tends to compress to absorb the energy.
Which type of spring used to measure weights in spring balance?
The helical tension spring/ helical extension spring is used to measure weights in a spring balance.
If the spring is compressed completely and the adjacent coils touch each other, the the length of spring is called as?
If the adjacent coils touch each other, then the length of the spring is called as the “Solid length” of that spring.
Where is the Helical torsion spring is used ?
The helical torsion spring is used in door hinges, door closers, automobile starters, clipboards, mouse traps, etc.
