Abstract
The utility model discloses an inertia cone crusher eccentric balancing structure. The inertia cone crusher eccentric balancing structure comprises a crusher transmission spindle, an eccentric assembly and a connecting device of the transmission spindle and the eccentric assembly, wherein a balancing weight is fixed on the upper end part of the transmission spindle, the balancing weight and an eccentric block of the eccentric assembly are respectively provided with an umbrella-type surface for generating eccentric force, the umbrella-type surface of the balancing weight and the umbrella-type surface of the eccentric surface are same in quality and opposite to each other; the transmission spindle is rotatably arranged on the crusher base through a plurality of groups of bearings; the eccentric assembly is rotatably connected with the crusher spindle through the plurality of groups of bearings. According to the balancing mounting fixing structure of the inertia cone crusher disclosed by the utility model, the inertia force caused by the eccentric assembly to the rack is balanced by using the balancing weight, the circumferential vibration of the crusher is maximally reduced, the service life of a cushion block is prolonged, the rotation of the machine is more stable, and the use performance is stronger.
Description
Technical field
The utility model belongs to Design of Mining Machinery and makes the field, especially belongs to unit for inertial conic crusher and manufactures and designs the field, particularly the unit for inertial conic crusher eccentric balance weight structure.
Background technology
At present, unit for inertial conic crusher adopts eccentric assembly tumbler that broken power is provided, in actual production process, rotate the centrifugal action that produces because of eccentric assembly, make the frame of machine also produce larger circumferential inertia force, cause the vibration force of machine larger, and larger vibration causes larger injury to all parts on machine, as the cushion blocking lifetime of install machinery, easily loosening, fracture etc. of fastening bolt.Therefore when not reducing the crusher in crushing eccentric force, need to lower the rotational vibration of Integral-crushing machine as far as possible.
Summary of the invention
The utility model discloses a kind of unit for inertial conic crusher transmission counter weight device structure according to the deficiencies in the prior art.Problem to be solved in the utility model is to provide a kind of being convenient for changing, and serviceability is strong, has reduced to greatest extent the disintegrating machine rotational vibration, the counter weight device structure of non-damageable unit for inertial conic crusher.
The utility model is achieved through the following technical solutions:
The unit for inertial conic crusher eccentric balance weight structure, the jockey that comprises disintegrating machine transmission main shaft, eccentric assembly and transmission main shaft and eccentric assembly, it is characterized in that: the upper end setting of described transmission main shaft is fixed with balancing weight, the eccentric block of balancing weight and eccentric assembly has respectively the umbrella shape face that produces eccentric force, and the umbrella shape face of balancing weight and the umbrella shape face of eccentric block are identical in quality and be oppositely arranged.
Described transmission main shaft rotatably is mounted on crusher machine seat by many groups bearing.
Described eccentric assembly is rotationally connected by many groups bearing and crusher axis.
Unit for inertial conic crusher has been installed the equiponderant balancing weight of the sector relative position of and eccentric assembly eccentric block in the upper end of transmission main shaft when install connecting.During machine run, the out-of-balance force that the inertia force that produces with the weighting block on transmission main shaft comes balance to produce because of eccentric assembly.
In sum, the utility model helpfulness, the counterweight mount fixing structure of the utility model unit for inertial conic crusher, by having used the balancing weight balance because of the inertia force of eccentric assembly to the frame generation, reduced to greatest extent the disintegrating machine rotational vibration, increased the service life of cushion blocking, had a machine in operation more steady, serviceability is stronger.

The specific embodiment
Below by the specific embodiment and accompanying drawing, the utility model is further illustrated.Embodiment is used for explanation the utility model, limits never in any form the utility model.
In conjunction with Fig. 1 and Fig. 3.
The unit for inertial conic crusher eccentric balance weight structure, the jockey 4 that comprises disintegrating machine transmission main shaft 1, eccentric assembly 5 and transmission main shaft 1 and eccentric assembly 5, transmission main shaft 1 upper end arranges and is fixed with balancing weight 3, balancing weight 3 has respectively with the eccentric block 2 of eccentric assembly 5 the umbrella shape face that produces eccentric force, and the umbrella shape face of balancing weight 3 and the umbrella shape face of eccentric block 2 are identical in quality and be oppositely arranged.
Transmission main shaft 1 rotatably is mounted on crusher machine seat by many groups bearing.Eccentric assembly 5 is rotationally connected by many groups bearing and crusher axis.
As Fig. 1, Fig. 2 and shown in Figure 3: unit for inertial conic crusher balancing weight mounting structure, to again the upper end of balancing weight 3 with transmission main shaft 1 be connected after 1 assembling of bearing and transmission main shaft, to be assemblied in jockey 4 upper end of balancing weight 3 again, be connected in the lower end of eccentric assembly 5.When machine turned round under the driving of transmission main shaft 1, eccentric assembly 5 produced centrifugal force and makes eccentric assembly 5 skews, has further produced larger centrifugal force.Produced larger inertia force because centrifugal force makes the machine frame, and the balancing weight 3 on transmission main shaft 1 rotates and produces reverse inertia force, balance the inertia force that produces of eccentric assembly 5, increased life-span of beam, make mechanical stability against short circuit stronger.
Fig. 4 is existing disintegrating machine drive mechanism schematic cross-section, as shown in the figure: after without counterweight block structure, bearing and transmission main shaft 1 being assembled, then will be assemblied in ball cage type hitch bar 6 upper end of transmission main shaft 1, and be connected in the lower end of eccentric assembly 5.When machine turned round under the driving of transmission main shaft 1,5 pairs of eccentric assemblies rotated the inertia force of generation to the larger inertia force of frame generation of machine, make each parts of machine stressed larger.
