Flywheel of Jaw Crusher

A flywheel is used as a reservoir of energy in machines. It stores the excess of energy when the supply is more than the requirement and utilizes the same when the rate of supply of energy falls. Basically it is used as a storage device for rotational energy. Flywheels helps to stabilize the rotation of the shaft when a varying torque is exerted on it by its power source; by resisting changes in their rotational speed. Flywheels can be used to produce very high power pulses for experiments, where drawing the power from the public network would produce unacceptable spikes.

Role of Flywheel in Jaw crusher

From the study of kinematic behavior of jaw crushers it has been found that for one complete rotation of the crank the forces developed on the moving jaw plate varies. At some region this force is sufficiently large to crush the material and in some zone this force could produce a stress less than the ultimate stress of the fed material. Hence to get the fed crushed in a regular time the energy lost during over supply should be utilized when the supply value falls below the requirement mark. To produce this effect every jaw crusher is equipped with a heavy flywheel with significant moment of inertia.
