Abstract
The utility model belongs to the technical field of machinery, and relates to a spindle pair, in particular to a spindle pair on a cone crusher, which solves the problems of unreasonable structural design, insufficient strength and the like. The spindle pair comprises a cylindrical inner ring and a cylindrical outer ring, wherein the inner ring is fixed into the outer ring. The spindle pair is characterized in that the surface of the outer ring is provided with a plurality of bumps, and the end face of the outer ring is provided with a plurality of connecting holes. The spindle pair has the advantages that connection and installation of the spindle pair are facilitated by the aid of a connecting hollow column perpendicular to the outer ring, the spindle pair can be positioned by means of adjusting the bumps, additionally, the inner ring and the outer ring are made of stainless steel, rigidity of the inner ring and the outer ring is enhanced, and the service life of a cone core is prolonged.
Description
Technical field
The utility model relates to field of mechanical technique, and it is secondary to relate to a kind of main shaft, and the main shaft that especially relates on a kind of cone crusher is secondary.
Background technology
During cone crusher (gyratory crusher) work; The rotating tee of motor crosses belt pulley or shaft coupling, power transmission shaft and conus portion are fixedly done the swing campaign around one down at the forced to move of eccentric bushing; Thereby when making the broken wall of gyratory crusher and near the time and leave and be packed in the white wall surface that rolls that adjustment puts; Ore is constantly impacted, extruding and flecition and realize the fragmentation of ore in crusher chamber.In the time can not breaking foreign matter through crusher chamber or because of the overload of certain reason machine, the spring insurance system is realized insurance, and gape increases, and foreign matter is discharged from crusher chamber, is stuck in ore discharge stone like foreign matter and can uses clear chamber system, makes ore discharge continue to increase, and makes foreign matter get rid of crusher chamber.Under the effect of spring, gape automatically resets, the mechanical recovery operate as normal.Divide the coarse crushing gyratory crusher, in three kinds of broken gyratory crusher and gyratory crushers in small, broken bits.The main shaft pair is one of part indispensable in the cone crusher, and it is installed in the outerface of spindle, is used to protect main shaft.The main shaft pair exists the some shortcomings part at present, and unreasonable such as the existing structure design, problems such as insufficient strength still exist.
The utility model content
The purpose of the utility model is to the problems referred to above, provides a kind of intensity high, rational in infrastructure, and the main shaft of long service life is secondary.
For achieving the above object; The utility model has adopted following technical proposal: the main shaft on this cone crusher is secondary; Comprise columniform inner ring and outer ring, described inner ring is fixed on inside, outer ring, it is characterized in that; Surface, described outer ring is provided with several projections, and cycle surface is provided with several connecting holes.
In the main shaft pair on above-mentioned a kind of cone crusher, described outer ring low side be provided with the outer ring perpendicular be connected open tubular column.
In the main shaft pair on above-mentioned a kind of cone crusher, stainless steel manufacturing manufacturing is adopted in described inner ring and outer ring.
Compared with prior art, the advantage of the utility model is: the connection open tubular column that the outer ring is perpendicular, be convenient to main shaft secondary connection and installation; Through regulating projection, just can realize the location that main shaft is secondary, in addition, inner ring and outer ring have increased its rigidity through the stainless steel manufacturing, have prolonged the service life of cone core.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Among the figure, inner ring 1, outer ring 2, projection 21, open tubular column 3.
The specific embodiment
As shown in Figure 1; Main shaft on the cone crusher is secondary, comprises columniform inner ring 1 and outer ring 2, and described inner ring 1 is fixed on 2 inside, outer ring; 2 surfaces, described outer ring are provided with several projections 21; Through regulating projection 21, just can realize the location that main shaft is secondary, outer ring 2 end faces are provided with several connecting holes.Described inner ring 1 adopts stainless steel manufacturing manufacturing with outer ring 2, and inner ring 1 passes through the stainless steel manufacturing with outer ring 2, has increased its rigidity, has prolonged the service life of cone core.Described outer ring 2 low sides be provided with outer ring 2 perpendicular be connected open tubular column 3.The connection open tubular column 3 that outer ring 2 is perpendicular is convenient to main shaft secondary connection and installation.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as inner ring 1, outer ring 2, projection 21, open tubular column 3 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
Claims (3)
1. the main shaft on the cone crusher is secondary, comprises columniform inner ring (1) and outer ring (2), and described inner ring (1) is fixed on inside, outer ring (2), it is characterized in that, surface, described outer ring (2) is provided with several projections (21).
2. main shaft on the cone crusher according to claim 1 is secondary, it is characterized in that, described outer ring (2) low side be provided with outer ring (2) perpendicular be connected open tubular column (3).
