When the rotary swing jaw crusher of the invention operates, crushing force acts on the movable jaw, the force at the upper end of the movable jaw acts on the left eccentric center, the force at the lower end of the movable jaw changes the force direction after the lever action of the thrust plate, the rocker and the frame, and acts on the right eccentric center through the connecting rod, and the resultant force of the left eccentric center and the right eccentric force is mutually reduced because the left eccentric center and the right eccentric center of the shaft are on the same straight line, thereby reducing the load of the shaft and the bearing, and greatly prolonging the service life of the shaft and the bearing.
The lever mechanism of the swing jaw crusher with the reverse action of the force is a plane low pair, and has the characteristics of large bearing capacity, simple structure, easy lubrication and sealing and easy manufacture.
According to the rotary swing jaw crusher, different amplitude of rotary swing of the movable jaw and a circular-to-elliptical change track can be designed by adjusting the eccentricity of the eccentric shaft and the hinging position of the rocker and the frame.
The rotary swing assembly of the rotary swing jaw crusher is characterized in that a movable jaw is manufactured into a trough and is installed upwards at a horizontal or certain inclination angle, and the rotary swing assembly can be used in the fields of heavy load feeding, screening, physical destressing of mechanical parts, casting shakeout and the like.
The swing assembly of the swing jaw crusher is characterized in that a movable jaw is made into an impact head and a fin and is installed downwards in a horizontal or certain inclination angle, and the swing assembly can be used in the fields of striking, jumping type travelling mechanisms and the like.
The swing assembly of the swing jaw crusher of the invention, which takes other rods except a double eccentric shaft as output, is installed in different square angles and can be used in other fields.
To sum up: the movable jaw swing assembly of the swing jaw crusher is essentially a single-shaft double-crank seven-rod mechanism, the cranks are arranged on two sides of the shaft, the two cranks are arranged in a straight line with the center of the shaft, the force applied to the lower end of the movable jaw is changed by the leverage of the rocker and the frame, and then the force of the other crank is transmitted, so that the force of the two cranks is synthesized and reduced, and the problem of the superposition of the synthesized stress of the load of the shaft and the bearing is solved; the lever mechanism is a plane low pair with the characteristics of large load, easy lubrication and easy sealing, and has a simple structure, so that the beneficial effects of the movable jaw rotary pendulum assembly (a single-shaft double-crank seven-lever mechanism) of the rotary pendulum jaw crusher are quite remarkable.
