The springs are defined as an elastic body which stores mechanical energy and gets distorted when loaded and regains its original shape when a load is removed. Springs main function is to get distorted when it is loaded and recover its original shape when the load is removed.
Types Of Springs
Types Of Spring On the Basis of Shape
1) Helical Or Coil Spring
It is a spring which is made up of a wire coiled in the form of the helix. It is made to handle tensile and compressive loads.
2) Conical And Volute Springs
These are the compression spring have conical shapes. The conical springs are wounded with a uniform pitch whereas the volute springs are wounded in the form paraboloid with constant pitch and lead angles. Under compression, coils of these springs slide past each other and make the spring to compress to a very shorter length.
3) Torsion Spring
It is a spring that works on torsion or twisting. It stores the mechanical energy when twisted.
4) Laminated Or Leaf Spring
It is a type of spring which is mostly used in automobile suspension, electrical switches and bows. It consists of a number of flat plates (known as leaves) of varying lengths held together by means of clamps and bolts.
5) Disc Or Belleville Spring
It is a disc-shaped spring. It is commonly used to apply tension to a bolt. It is also called as Belleville washers and conical compression washers.
