Fly Wheel

Use of the product:

The supporting jaw crusher is used to adapt to mines, construction, water conservancy and other fields. It is used for the crushing operation of all kinds of materials (medium and hard and hard materials), transmits power, ensures the smooth operation of the crushing operation, helps the equipment to operate stably and efficiently, and adapts to the crushing needs of the whole scene.

Application scenario:

Flywheel is a key power energy storage component in jaw crushers. It is widely used in mine crushing, sand and stone aggregate production lines and metallurgical building materials industries. It is used to balance the operating load of equipment and store and release kinetic energy, so as to ensure the continuity and stability of the crushing process.

In practical application, the flywheel is installed at both ends of the spindle of the jaw crusher to balance the reciprocating movement of the moving jaw through inertial action, making the motor load more uniform, reducing impact fluctuations, and improving the smooth operation of the equipment. In the gravel production line, Flywheel is an important part of the jaw-breaking power system, which plays an important role in improving the efficiency of the whole machine and reducing energy consumption.

In addition, this component is widely used in mining, cement building materials and infrastructure engineering, especially suitable for high-impact and high-load coarse crushing conditions. It is one of the important components to ensure the stable operation of jaw crushers.

FAQ：

Q：What is the Fly Wheel and what role does it play in PE/PEX jaw crusher?

A：Fly Wheel, is installed at the left and right ends of the jaw-breaking eccentric shaft. The integrated belt groove of the flywheel on one side acts as a transmission pulley, and the counterweight balance flywheel on the other side has three core functions:

• Energy storage and energy release: the moving jaw air return storage motor energy, the crushing and extruding stone releases the inertial force instantly, smoothly offsets the instantaneous crushing resistance, balancing the motor load, and reducing the peak power consumption;
• Counterweight balance of the whole machine: offset the reverse inertia caused by the reciprocating swing of the jaw, greatly reduce the vibration of the whole machine of the equipment and the shaking of the fuselage, and extend the service life of the frame, bearing and bushing;
• Power transmission: The grooved flywheel undertakes the power of the triangular belt, transmits the motor torque to the eccentric shaft, and drives the moving jaw to complete the crushing operation.

Q：Which jaw crusher models are suitable for Fly Wheel?

A：The full range is suitable for PE, PEX, EC, JC full-specification jaw crusher, divided into standard weight flywheel, widened multi-slot transmission flywheel, supporting eccentric shaft, Bushing bushing, Toggle Plate thrust plate complete set supply.

Q：What kind of flywheel should be used for the hard rock open-pit mine production line?

A：Prioritise high-strength all-in-one cast steel Fly Wheel. The instantaneous impact of large hard rock ore is large, and the ductile cast iron is prone to stress cracks; the overall rigidity of the cast steel flywheel is strong, and the long-term high-frequency vibration is not easy to crack and deform, which greatly reduces the frequency of downtime and maintenance.

Q：How to choose a flywheel for small and medium-sized solid waste and limestone fields?

A：Just choose the QT450 ductile iron flywheel. The material impact load is small, the shock absorption balance effect meets the standard, the procurement cost is lower, and it is suitable for intermittent crushing operation conditions.

Q：What faults will accelerate the cracking and damage of the flywheel?

A：1. Large metal iron blocks are frequently stuck in the crushing cavity, and the instantaneous huge impact causes flywheel cracks; 2. The flywheel keyway is worn, the flat key is loose, and the rotation of different centre produces violent deviation vibration; 3. The eccentric shaft bushing is stuck, the lubrication fails, and the equipment load increases sharply to impact the flywheel; 4. The foundation is uneven, and the shock absorber base fails, Long-term tilt resonance fatigue cracking of the whole machine; 5. Unbalanced belt elasticity, uneven multi-slot force, continuous wear of the keyway on one side.
