It is made of a band of steel wrapped around itself a number of times to create a geometric shape as shown in figure 4. Mainly used for torque transmission The ends of the spring are attached to other application objects, so that if the object rotates around the center of the spring, it tends to push the spring to retrieve its normal position. It releases the load in an arc around the axis as shown in figure3. It is also a form of helical spring, but it rotates about an axis to create load.

It tends to bow sideways when applying a compressive load. They are as follows:Īmong the four types, the plain end type is less expensive to manufacture. There are mainly four forms of compression springs as shown in figure2. By applying the load the spring contracts in action.

It is made of round wire and wrapped in cylindrical shape with a constant pitch between the coils. The gap between the successive coils is larger. By applying load the spring elongates in action as it mainly depends upon the end hooks as shown in figure1. The wire is coiled in a sequence that the turn is at right angles to the axis of the spring. The gap between the successive coils is small. It has some means of transferring the load from the support to the body by means of some arrangement. HELICAL SPRINGS: It is made of wire coiled in the form of helix with circular, square or rectangular cross-section.įigure1 shows a helical tension spring. Helical Compression Springs before loading remains in tension, while Helical Tension Springs before loading remains in compression. Helical Coil Springs again classified in 2 subtypes:Ī. In other words it is also termed as a resilient member.īased on the shape behavior obtained by some applied force, springs are classified into the following ways:ġ. They can return to their original shape when the force is released. Springs are elastic bodies (generally metal) that can be twisted, pulled, or stretched by some force. The portion highlighted in red color is Suspension’s Helical Compression Spring.
