- The frame of the jaw crusher, is a four-wall rigid frame with upper and lower openings, which is used to support the eccentric shaft and bear the reaction force of the crushed material. It requires a certain degree of strength and stiffness. The frame structure is basically an integrated casting, and the large frame structure needs to be cast in sections, and then firmly linked into a whole by bolts, and the casting process is complicated.
2.Jaw plate and side cheek plate, fixed jaw plate and movable jaw plate are composed of jaw bed. The jaw plate is the working part, which is fixed on the jaw bed with bolts and wedge iron. The jaw bed of the fixed jaw is the front wall of the frame , The movable jaw bed is suspended on the circumference, and must have sufficient strength and rigidity to withstand the crushing reaction force, so most of them are cast steel or cast iron.
3.The transmission part, the eccentric shaft is the main shaft of the crusher, which receives huge bending and torsion force. It is made of high carbon steel and is well processed. The heat-treated bearing bush is cast with babbitt alloy.
4.Adjustment device, the adjustment device generally adopts the wedge type, which is composed of two wedges, front and rear, which can be moved back and forth, and can withstand the backward version. The rear wedge is an adjusting wedge, which can move up and down. The screw makes the rear wedge move up and down to adjust the size of the outlet.
5.Flywheel, the flywheel of the jaw crusher is used to store the energy during the empty stroke of the movable jaw, and then used for industrial formation, so that the work of the machine tends to be uniform. The pulley also acts as a flywheel.
6. The eccentric shaft bearing usually adopts centralized circulating lubrication. The bearing surfaces of the mandrel and the thrust plate are generally lubricated with grease through a manual oil gun.
