Jaw crusher structure outlined in Southeast Asia
Movable jaw plate movement is by means of connecting rod, the thrust plate mechanism to achieve. It is composed of the flywheel, the eccentric shaft, connecting rod, the thrust front and rear thrust plate. Flywheels were installed at both ends of the eccentric shaft, eccentric shaft is supported in the main bearing chassis side walls, the upper portion of the connecting rod mounted on the eccentric shaft, front and rear end of the thrust plate are supported on both sides of the lower link brackets the cradle and the other end of the support plate in the forward thrust moving jaw toggle plate holder in the lower part, the other end of the support plate in the back pressure on the rear wall of the rack mount brackets. When the motor through the pulley driven eccentric shaft rotation, so that the connecting rod in motion. Link up and down movement, driven by the thrust plate movement. Due to the movement of the thrust plate changing the inclination angle of the results, so the movable jaw plate to hang around the shaft to reciprocate, thereby crushing the ore. When the moving jaw swings forward, the horizontal rod by a spring to balance the inertial force of the movable jaw plate and the thrust generated by the thrust plate and moving jaw so closely to warrant separation. When the moving jaw back, spring but also as an assistance role.
Since the flywheel jaw crusher is intermittent work, work that is idle
stroke and stroke, so it’s very uneven load motor. For the load evenly,
it is necessary when moving jaw moves backward, the idle stroke of the
energy stored up, so that when the working stroke, and then release all
the energy out. Utilizing the principle of inertia, the ends of each
eccentric shaft being provided with a flywheel can achieve this goal. To
simplify the structure of the machine, which is generally regarded
serves as a flywheel power is transmitted by a pulley. For two motors
are driven using a large jaw crusher, two flywheels are made from the
pulley, the pulley that is also taking off round action.
The eccentric shaft or spindle which is an important part of crusher
simple pendulum jaw crusher moving jaw suspension shaft called a
spindle. The eccentric shaft is driven by the connecting rod up and down
movement of the main parts, due to the crushing force under a lot of
work when they are generally made of high quality steel production.
According to China’s resources, the eccentric shaft large jaw crusher to
the use of manganese, molybdenum, vanadium, manganese, boron and
molybdenum and chromium molybdenum steel is more appropriate. Small jaw
crusher is used 45 steel. Eccentric shaft should be tempered or
normalizing heat treatment to improve the strength and wear resistance.
Spindle commonly used 45 steel.
