Jaw Crusher Introduction of performance critical components

First, the jaw plate and side guard plate : by the fixed jaw and movable jaw jaw jaw bed and composition, is working part jaw plate , fixed with bolts and wedge in Hubei bed. The bed is the fixed jaw jaw rack wall , moving jaw jaw hanging in bed week , have sufficient strength and rigidity to withstand the crushing reaction force , which is mostly cast steel or cast iron.

Second, the frame: The frame is a rigid frame walls of the upper and lower openings , used to support the eccentric shaft and bear fragmentation reaction of materials , requires sufficient strength and stiffness , usually with the whole cast steel , minicomputers quality cast iron can also be used instead of steel .

Third, the transmission member : Ceramic ball milleccentric shaft axis , by a huge bending torque , high- carbon steel . Eccentric part shall be finishing , heat treatment, bearing liner with babbitt pouring . Eccentric shaft pulley mounted at one end , a second end attached the flywheel .

Fourth, the flywheel : jaw crusher jaw flywheel to store dynamic energy when air travel , and then used in industrial forming , so that the mechanical work is in line uniformly. Also plays a role in the flywheel pulley . Learned from the flywheel often cast iron or cast steel , minicomputer often made integral flywheel . Flywheel manufacture, installation should pay attention to static equilibrium .

Fifth, the adjustment device: a wedge adjustment device , plate and hydraulic , etc. , generally wedge , wedge composed by the front two , the former wedge can be moved back and forth , withstood push plate ; After the wedge is adjusting wedge , can be moved up and down , two backward inclined wedge bonding , the rear wedge by the screw moves up and down to adjust the size of the discharge port .

Six , lubrication devices: eccentric shaft bearings are usually centralized lubrication . Mandrels and thrust plate support surface generally use the grease gun oil to the oil by hand . Movable jaw swing angle is small, between the spindle and bearing lubrication difficulties , often open several axial bearing oil groove bottom , middle to open a ring connected to the tank to make it , and then forcibly injected dry butter oil pump lubrication.
