Abstract

The utility model provides a cone crusher which is mainly composed of a shell body, an inner and an outer cones, an imbalance rotor, a support and driving components. The utility model is characterized in that the outer cone is fixed on the upper part of the shell body. The inner cone is arranged on a base seat. A central shaft of the cone crusher is inserted into a shaft sleeve of an imbalance rotor. The imbalance rotor is supported by an intermediate shaft with an oil passage through a ball attachment. The transmission of the cone crusher is characterized in that a crank of the intermediate shaft is driven by a motor and is pushed by an eccentric push rod mounted on the crank. The separation of a supporting and a transmitting functions are achieved. The swing of the inner cone is not limited. The structure which has the advantages of flexible operation, low failure rate, high reliability, high production rate, high crushing ratio and long service life is suitable for being used in the industries for crushing materials, such as the mineral industry, the construction material industry, the metal industry, etc.

Description

Conic crushing engine

The utility model relates to crushing mechanism, the gyratory crusher of a kind of fine crushing of more specifically saying so.

Traditional eccentric disintegrating machine operating efficiency is extremely low.Use in the world now biased rotor type gyratory crusher more generally, its crushing efficiency improves more than four times than the eccentric disintegrating machine of tradition.This disintegrating machine all has an Outer Taper and an inner cone to be complementary, and inner cone is the axle support of sphere by two ends, and an imbalance rotor relies on sliding bearing to be sleeved on the axle.Two kinds of schemes have been used in the transmission of imbalance rotor: a kind ofly be the elastic compensating shaft coupling, another kind is the lower peripheral surface joint dress transition power transmission shaft at axle.The former shortcoming is, the imbalance rotor of rotating with respect to the axle center of casing have bigger radially and angular displacement, theoretical calculating show, shaft coupling can not transmitting large torque, limited the power of disintegrating machine, in addition, during axle sleeve work, the statuary column plug is the same in motion, when the sphere by inner cone supports oiling outside in, the rotor that is rotating will hinder lubricating oil and enter the axle and the gap of axle sleeve, so the driving section easy break-down.The latter's shortcoming is, because driving member is again simultaneously support member (being that driving member is finished transmission simultaneously and supported two functions), functional reliability is greatly reduced, shortened the maintenance of equipment phase, in addition, it has also limited the amplitude of oscillation of inner cone, and the productivity ratio and the ratio of reduction are descended.Two kinds of schemes are all not ideal enough.

The purpose of this utility model is to propose a kind ofly can to improve functional reliability, can prolong the maintenance interval again, enlarge the gyratory crusher of process application scope.

In order to achieve the above object, the technical solution that the utility model is taked is: this device is by housing, interior Outer Taper, imbalance rotor, support and the drive disk assembly composition, Outer Taper is by the top of screwed connection at housing, inner cone places on the interior sphere base of casing cavity, this inner cone has a central shaft to stretch into to be located in the sliding bearing sleeve of imbalance rotor in the sphere base, imbalance rotor is supported by the globe joint upper end, the globe joint lower end places boring a hole of jackshaft upper surface, the jackshaft upper end also is provided with crank and the eccentric push rod that is contained in above the crank, the lower end connects motor by driving-belt, globe joint, jackshaft has the oil transportation hole and communicates with oil circuit.When jackshaft is rotated by motor drives, it is crushing force that crank promotes the relative inner cone central shaft rotation of imbalance rotor generation centrifugal force by eccentric push rod, separate with the function of drive disk assembly owing to realize supporting, be provided with lubricant passage way, avoid checking and balance, thereby reach the purpose that improves complete machine functional reliability, prolongation maintenance of equipment phase, enlarges the process application scope.

The utility model has the advantages that: 1, owing to realized that supporter separates with the function of drive disk assembly, make imbalance rotor footpath, angular displacement can not influence the drive disk assembly operate as normal, this has just improved the complete machine functional reliability widely, prolonged the maintenance of equipment phase, simultaneously the amplitude of oscillation of inner cone is not pind down by drive disk assembly, thereby productivity ratio and the ratio of reduction obtain corresponding raising; 2, owing to be provided with special lubricant passage way, lubricating oil is not hindered by rotor can and directly enter the gap of axle and axle sleeve by oil circuit, makes that rotating shaft is lubricated to go slick, and has reduced friction, the service life of prolongation equipment.

Fig. 1 is the overall structure cutaway view of gyratory crusher of the present utility model.

Fig. 2 is that the A-A of the imbalance rotor among Fig. 1 is to view.

Below in conjunction with accompanying drawing gyratory crusher of the present utility model is described in further detail.

In Fig. 1, casing 1 is being adorned Outer Taper 3 by adjusting screw thread 2, inner cone 5 and inner cone central shaft 6 are housed on machine Internal Spherical Surface base 4, imbalance rotor 8 is installed by sliding bearing sleeve 7 in outside at inner cone central shaft 6, its support is that both ends of the surface are spherical globe joint 9 up and down, the globe joint center has oil transportation hole 10, the upper end sphere 11 of globe joint places boring a hole in 12 of imbalance rotor 8, what lower end sphere 13 placed jackshaft 15 bores a hole 14, jackshaft 15 upper ends are provided with crank 16, are adorning eccentric push rod 17 on it, and jackshaft 15 is contained in the bearing 18, drive by driving-belt 20 by motor 21, and have oil transportation hole 10 connections of oil circuit 19 and globe joint 9.

Fig. 2 is that the A-A of the imbalance rotor among Fig. 1 is to view.As seen from the figure, adorning push rod 17 on the crank 16, promoting imbalance rotor 8 from the side around central shaft 6 widely different commentaries on classics.

This gyratory crusher is worked in the following manner: when jackshaft 15 rotation, crank 16 promotes imbalance rotor 8 by push rod 17 from the tangential direction of imbalance rotor, the relative central shaft 6 of this rotor and rotating, and produce centrifugal force, promptly form crushing force.When imbalance rotor 8 moved radially, push rod moved along its outer wall, produced the widely different transhipment of three phase spaces thus and moved, because the deflection of the deflection of rotor 8 and inner cone 5 does not overlap, the direction of rotation of inner cone and the amplitude of oscillation will lag behind, and for alleviating this side effect, push rod 17 will be made with high-abrasive material.

The lubricated of bearing 7 and sphere base 4 is through the oil circuit 19 of jackshaft 15 and oil transportation hole 10 fuel feeding of globe joint 9, globe joint 9 is only as the support of imbalance rotor 8, thereby transmission is separated with support two big functions of components, be that globe joint 9 plays a supportive role, 16 gearings of the crank on the jackshaft 15.
