Let me show you the main componets of jaw crusher
1. Rack chassis is rigid upper and lower walls of the opening frame for supporting the eccentric shaft and the crushing of materials to withstand the reaction, requires sufficient strength and stiffness, usually with a cast the whole cast, minicomputer can also be used instead of high-quality cast iron steel. Cast to be sub-rack mainframe, and then link into the overall solid bolt, casting complex. Made small jaw crusher frame welded thick steel plate can also be used, but less stiffness.
2. Jaw plate and side plate protection :set by the jaw and jaw bed and board composition, board is working, regardless of jaw, the wedge bolt and fixed to the jaw bed. Jaw jaw is fixed rack wall bed, moving bed jaw jaw hanging in the week, and have sufficient strength and rigidity to withstand the crushing counter-force, which are mostly cast steel or cast iron.
3.Transmission :Parts crusher eccentric shaft is the main axis of the bending torque by a huge, high-carbon steel. Eccentric part of the required finishing, heat treatment, bearing with babbitt lining tile cast. Eccentric shaft pulley mounted at one end the other end mounted flywheel.
4.Adjusting device: adjusting device with wedge-type, plate and hydraulic, etc., generally wedge-style, the wedge formed by the front two, the first wedge can move, push plate to withstand; to adjust the wedge after wedge can be moved up and down, two wedges fit slope backward by the screw to move up or down to adjust the wedge after the discharge port size. Small jaw crusher discharge port after the adjustment is to use changes in the thrust bearing plate between the gasket and rack number to achieve.
5.Flywheel :jaw crusher flywheel to store the moving jaw when air travel is the energy, re-formed for the industry, so that mechanical work is in line uniformly. Also plays a role in the flywheel pulley. Often of cast iron or cast steel flywheel manufactured minicomputers often made integral flywheel. Flywheel manufacture, installation, pay attention to static equilibrium.
6.lubrication device:eccentric shaft bearing is usually concentrated lubricant circulation. Spindle and thrust plate support surface generally use the grease gun oil to the oil by hand. Jaw of the swing angle is small, so that between the spindle and bearing lubrication difficulties, often in the opening number at the bottom of the axial bearing oil groove in the middle to open a ring connected to the tank to make it, then pump to force the butter into the dry lubrication.
