The flywheel is an important component in the crusher and is more common in the jaw crusher. The flywheel of the crusher mainly uses the inertia principle of the object. The flywheel mainly plays the role of storing and releasing energy, balancing the motor load, transmitting power, reducing mechanical vibration, and overload protection in the process of crushing materials.

Storing and releasing energy

The flywheel is generally disc-shaped and has a large moment of inertia. The working process of the crusher is intermittent, with a working stroke and an idling stroke. During the idling stroke, the flywheel stores energy. Some flywheel edges are designed to be thickened or have spokes to increase weight and moment of inertia and improve energy storage effects; when the moving jaw plate squeezes the material, the flywheel releases the stored energy to help the crusher complete the crushing operation, so that the load of the motor tends to be uniform, reduce the rated power of the motor, and reduce the fluctuation of the mechanical rate.

Balancing the motor load

Due to the intermittent operation of the crusher, the motor load is extremely unbalanced. The flywheel stores and releases energy to make the motor load more uniform and prevent the motor from being overloaded when crushing materials.

Power transmission

In some crusher designs, the flywheel also serves as a pulley to transmit power, simplifying the equipment structure. For example, in a large jaw crusher with two motors, both flywheels can be used as pulleys.

Reducing mechanical vibration

The inertia of the flywheel helps to reduce mechanical vibration, improve the stability and safety of the equipment, and extend the service life of various parts of the equipment.

Overload protection

When the crusher encounters an unexpected overload, the inertia of the flywheel can buffer the impact load to a certain extent and prevent other parts of the crusher from being damaged by excessive force in an instant. At the same time, the existence of the flywheel also provides a certain reaction time for the control system of the crusher so that corresponding protective measures such as shutdown can be taken.

During the working process of the crusher, the energy stored in the flywheel will be released to help the crusher overcome the instantaneous resistance, so that the movement state of the crusher remains relatively stable, and ensure that the crushing work can be carried out continuously and effectively. As a crusher flywheel manufacturer, when designing the flywheel, we will accurately calculate the inertia moment required by the flywheel according to the working parameters of the crusher such as power, speed, and crushing force to ensure that the flywheel can store enough energy to meet the working needs of the crusher. During the production process, we conduct strict dynamic balancing tests to ensure that the mass is evenly distributed, the axis of rotation coincides with the center of gravity, and the machine can operate efficiently. The flywheels we manufacture have been praised by customers with satisfaction. If you are interested, please contact us and we will serve you immediately and give you a satisfactory answer.
