Jaw crusher main components

1 rack

Opening the upper and lower walls of the rack rigid frame, for supporting the eccentric shaft and subjected to the reaction force of broken material, require sufficient strength

and rigidity, the general overall cast steel, cast iron minicomputer can also be used instead of high-quality steel. Mainframe Rack need segmented cast, and then bolt

Strong links into a whole, the casting sieving machine process complicated. Homemade small jaw crusher frame welded thick steel plate can also be used, but the stiffness is poor.

2 jaw crusher jaw plate and side guard plate

By the fixed jaw and movable jaw jaw jaw bed and plates, jaw plate is work regardless, fixed with bolts and wedge in the jaw 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 China Vibrating Screen reaction force, which is mostly cast steel or cast iron

.

3 jaw crusher transmission parts

Crusher eccentric 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.

4 jaw crusher adjustment device

There are 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; wedge after wedge is adjustable, up and down moving backward inclined two wedge bonding, by the screw is moved up and down the rear wedge

Adjusting the size of the discharge port. Small jaw crusher discharge port after the adjustment is to use the change in the thrust plate bearing shims between the rack number to

achieve.

5 Jaw Crusher Flywheel

Jaw crusher jaw flywheel to store energy during air travel, and then used in industrial form, so that the mechanical work is in line uniformly. Also plays a role in the flywheel

pulley. Flywheel often cast iron or steel manufacturing, minicomputer often made integral flywheel. Flywheel manufacture, installation to

Note that static balance.

6 jaw crusher lubrication device

Eccentric shaft bearings are usually centralized lubrication. Mandrels and thrust plate support surface generally use the grease gun oil to the oil by hand. Moving 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

Pass, and then forcibly injected dry butter oil pump lubrication.
