Gyratory crusher is generally used for broken mine ore, building waste etc., and the working principle of gyratory crusher is to pass through
Eccentric part rotation inside motor drive crusher, the movement of eccentric part rotate driving mantle by mantle and bore it surely
Between the continuous variation of crusher chamber size that is formed, ore materials are squeezed, to reach crushing effect.
When being full of material in crusher chamber, rub simultaneously between material and fixed cone and mantle, and generate and revolved with eccentric element
Turn contrary frictional force, mantle is caused to bore rotation direction that is static or boring surely and eccentric element rotation direction phase surely relatively
Instead.
When there is no material in crusher chamber, i.e., when unloaded, frictional force generated to mantle without material, but eccentric element with
Frictional force is generated between mantle, this frictional force causes mantle that eccentric element is followed to rotate together, or even with eccentric element with identical
Speed rotation.
During the loading process, material will impact mantle, and the active force between mantle and eccentric element is caused to increase suddenly,
It is larger to eccentric element and main shaft impact force, damage eccentric element and main shaft.

12, main shaft 12 is used to support eccentric cover section 3 and mantle portion 2, and 12 top of main shaft is equipped with ball bearing 17, and ball bearing 17 is used to support
Mantle portion 2, and the braking friction for preventing mantle portion 2 from rotating is provided；Eccentric cover section 3 includes eccentric bushing 31, and eccentric bushing 31 is installed
Inside rack 11,31 sets of eccentric bushing in 12 outside of main shaft and around the rotation of main shaft 12, under the driving of motor, eccentric cover section 3
Rotation, and then mantle portion 2 is driven to swing；Mantle portion 2 includes cone 21, and cone 21 is mounted on 17 top of ball bearing, and cone 21 is logical
It crosses mating spherical surfaces to be connected with ball bearing 17,21 lower part of cone is set in 31 outside of eccentric bushing, and cone 21 is outside eccentric bushing 31
Rotation；Anti-spin system includes the ball 22 of the sealing ring 16 being arranged in rack 11 and the setting of 21 lower part of cone, and ball 22 is located at
16 top of sealing ring, ball 22 are connected by way of mating spherical surfaces with sealing ring 16.
Sealing ring 16 uses floating seal ring, and ball 22 uses dust-proof ball.
16 lower part of sealing ring is provided with sealing ring support 13, and sealing ring support 13 is fixedly mounted in rack 11, sealing ring
For the setting of 16 lower ends in 13 inside of sealing ring support, 16 upper end of sealing ring is located at 13 top of sealing ring support.
Spring mounting hole 131 is provided in sealing ring support 13,16 bottom of sealing ring is provided with spring pilot hole 161, bullet
Spring 14 is installed, 14 other end of spring is placed in spring pilot hole 161 in spring mounting hole 131.
14 upper outside of spring is arranged with spring fairlead 15.When sealing ring 16 moves up and down, spring fairlead 15 is played
Guiding role.
Sealing ring 16 remains the state being in contact with ball 22 under action from the spring 14.
Ball bearing 17 is mounted on main shaft 12 using dismountable mode.
As shown in figures 1 and 3, mantle portion 2 is in the counterclockwise direction under gyratory crusher " zero load " operating status, in Fig. 3
Rotation, the centrifugal force and 3 mutual extrusion of eccentric cover section that eccentric cover section 3 acts on the mass center in mantle portion 2 generate dragging mantle portion 2
The driving force F1 of rotation, driving force F1 follow eccentric cover section 3 to rotate for mantle portion 2 is dragged；17 spherical surface internal cause gravity of ball bearing is made
With cone 21 and the friction of ball bearing 17 will generate the braking friction F2 for preventing cone 21 from rotating；Floating seal ring 16 is because dust-proof
The pressure of ball 22 acts on, and will generate the braking friction F3 for preventing mantle portion 2 from rotating.
Driving force F1 is limited in the region that the outer circle of eccentric cover section 3 is in contact with the inner hole of cone 21, and driving force F1
Direction remain constant, along the outer circle tangential direction of eccentric cover section 3, F1 is that counterclockwise, driving force F1 will be dragged at this time
Dynamic mantle portion 2 follows eccentric cover section 3 to rotate.
Ball bearing 17 generate braking friction F2 region be ball bearing 17 upper spherical in, and the direction of F2 be mantle
The opposite direction of 2 rotation direction of portion, the direction of F2 is clockwise at this time.
Braking friction F3 is limited in the spherical that floating seal ring 16 is in contact with dust-proof ball, direction according to
The variation of the rotation direction in mantle portion 2 and change, the rotation direction in direction and mantle portion 2 is on the contrary, the direction of F3 is suitable at this time
Clockwise.
Driving force F1 is greater than the sum of braking friction F2 and braking friction F3, therefore turn in mantle portion 2 and eccentric cover section 3
Dynamic direction is consistent, prevents mantle portion 2 from rotating with eccentric cover section 3.
As shown in Figure 4 and Figure 5, mantle portion 2 is along clockwise direction under gyratory crusher " load " operating status, in Fig. 5
Rotation, the centrifugal force and 3 mutual extrusion of eccentric cover section that eccentric cover section 3 acts on the mass center in mantle portion 2 generate dragging mantle portion 2
The driving force F1 of rotation；In 17 spherical surface of ball bearing due to gravity, cone 21 and ball bearing 17, which rub to generate, prevents cone 21
The braking friction F2 of rotation；Floating seal ring 16 will generate what prevention mantle portion 2 rotated because the pressure of dust-proof ball 22 acts on
Braking friction F3.
Driving force F1 is limited in the region that the outer circle of eccentric cover section 3 is in contact with the inner hole of cone 21, and driving force F1
Direction remain constant, along the outer circle tangential direction of eccentric cover section 3, F1 is counterclockwise at this time.
Under " load " state, mantle portion 2 it is continuous swing make material by rack 1(containing fixed cone) and mantle portion 2 friction
Power, while material generates opposition F4 to mantle portion 2, the direction of F4 is clockwise at this time.Directed force F 4 be greater than or
Person is equal to driving force F1, and the rotation direction in mantle portion 2 is different from the rotation direction of eccentric cover section 3 at this time, as clockwise
Or it is stationary.
Ball bearing 17 generate braking friction F2 region be ball bearing 17 upper spherical in, and the direction of F2 be mantle
The opposite direction of 2 rotation direction of portion, the direction of F2 is counterclockwise at this time.
Braking friction F3 is limited in the spherical that floating seal ring 16 is in contact with dust-proof ball, direction according to
The variation of the rotation direction in mantle portion 2 and change, the rotation direction in direction and mantle portion 2 is on the contrary, the direction of F3 is inverse at this time
Clockwise.
Braking friction F2 and braking friction F3 plays the role of that mantle portion 2 is prevented to rotate.
The above is preferred embodiments of the present invention, it is noted that for those skilled in the art,
The utility model is not limited to the embodiments described above, and under the premise of not departing from the utility model general idea, can also be done
Several changes and improvements out, these also should be considered as the protection scope of the utility model.
