Abstract
The utility model relates to the improvement of the transmission device of the moving cone of a cone crusher, composed of a main frame, a fixed cone, a moving cone, a main shaft, an eccentric sleeve and a transmission device. The utility model is characterized in that the eccentric sleeve (4) is windingly fixed to and rotates around the main shaft (3) of the main frame (7); the shaft central line of the eccentric sleeve (4) forms a definite angle with the shaft central line of the main shaft (3); the moving cone (2) contact the main shaft (3) through a spherical surface tile (8) and a spherical surface tile support (9); the inner surface of the moving cone (2) contact the eccentric sleeve (4) through a lining; the shaft central line of the moving cone (2) is coherent with that of the eccentric sleeve (4). Compared with the existing cone crushers, the utility model can raise rotating speed by 30 percents and increase yield by over 50 percents.
Description
The utility model relates to mine disintegrating machine equipment, the particularly improvement of the transmission device of gyratory crusher mantle.
Gyratory crusher is a kind of based on squeezing action, and accompanies by the equipment of crooked fragmentation.As shown in Figure 1.Material enters in the crusher chamber that forms with fixed awl (1) and mantle (2), and the mantle (2) that main shaft (3) links is along shaft centre line OO
1With eccentric throw R around disintegrating machine center line OO
2Rotation, because the change of spacing between mantle (2) and fixed awl (1) inner surface, material is squeezed, crooked, fragmentation and being discharged from outside the chamber.The gyratory crusher that generally uses as shown in Figure 2 at present.Mantle (2) and main shaft (3) are positioned at same shaft centre line and directly connect, and the excentric sleeve (4) that endoporus is made eccentric bellmouth is partly inserted in the taper of main shaft (3) bottom.When excentric sleeve (4) is driven by a pair of bevel gear of being made up of bevel gear wheel (5) and bevel pinion (6), the eccentric cycle swing of the corresponding do of main shaft (3).Because the friction between main shaft (3) and the excentric sleeve (4) is bigger, is easy to generate " biting " phenomenon, the mantle (2) and the binding site of main shaft (3) are ruptured, so that scrap.If increase the extruding force of mantle (2), the overstriking main shaft (3) that is bound to, and increase excentric sleeve (4) mutually, and Tab phenolphthaleinum causes the cost rising thereafter, and power consumption increases.
The gyratory crusher that provides a kind of excentric sleeve to rotate around dead axle is provided the purpose of this utility model.It has overcome the shortcoming of existing gyratory crusher, reduces excentric sleeve, improves the rotary speed of mantle, can increase the broken output of material.
The utility model is achieved in that main shaft is fixed on the mainframe, excentric sleeve is around main axis rotation, the shaft centre line and the spindle centerline of excentric sleeve have a certain degree mutually, mantle contacts with main shaft with the spherical bush frame by spherical bush, the mantle inner face contacts with excentric sleeve by lining, and the shaft centre line of mantle and the shaft centre line of excentric sleeve are consistent.
Fig. 1, gyratory crusher operation principle schematic diagram;
Fig. 2, existing gyratory crusher fundamental diagram;
Fig. 3, the utility model fundamental diagram.
Among the figure: 1. fixed awl, 2. mantle, 3. main shaft, 4. excentric sleeve, 5. bevel gear wheel, 6. bevel pinion 7. mainframes, 8. spherical bush, 9. the spherical bush frame is 10. gone up lining, 11. times linings, 12. thrust bearings
Below in conjunction with drawings and Examples the utility model is described in detail.
The utility model is the gyratory crusher that a kind of excentric sleeve rotates around dead axle, as shown in Figure 3.The shaft centre line of main shaft (3) and disintegrating machine center line OO
2Overlap, and be fixed on the mainframe (7), and excentric sleeve (4) is around main shaft (3) rotation, its center line OO
1With disintegrating machine center line OO
2Have a certain degree mutually, the shaft centre line of the shaft centre line of mantle (2) and excentric sleeve (4) is consistent, mantle (2) is by given eccentric throw cycle swing, and between the inner surface of fixed awl (1), apart from the time far away when near, the material that enters in the crusher chamber is pushed and broken.
When the utility model was implemented, mainframe (7) on the basis, was passed to basis with crushing force by bolted.Main shaft (3) is fixed on the mainframe (7), and an eccentric bushing lining as supporting usefulness is set between excentric sleeve (4) and the main shaft (3), and the shaft centre line of the shaft centre line of excentric sleeve (4) and main shaft (3) is mutually 2 ° 5 ' angle; Bevel gear wheel (5) is bolted to excentric sleeve (4) bottom, and is driven by the bevel pinion on the horizontal drive shaft (6); Excentric sleeve (4) is supported by one group of thrust bearing (12).An inversion counterbore that is used for mounting spherical watt (8) is arranged at the indent of mantle (2) bottom, with spherical bush (8) with bolted on it; Spherical bush frame (9) then is fixed on the top of main shaft (3), and spherical bush (8) closely contacts entirely with spherical bush frame (9).Mantle (2) inner face lining (10) and following lining (11) along the shaft centre line stationary distribution of mantle (2), last lining (10) is used to be enclosed within the external cylindrical surface periphery on the top of main shaft (3), and following lining (11) is used to be enclosed within the external cylindrical surface periphery of excentric sleeve (4).When excentric sleeve (4) was done eccentric rotation around static fixing main shaft (3), movement locus was OO shown in Fig. 1 gyratory crusher operation principle schematic diagram
1Around center line OO
2Track with eccentric throw R rotation, and the shaft centre line of the shaft centre line of mantle (2) and excentric sleeve (4) is because the location association of upper and lower lining, fulfil its same movement locus equally, promptly the shaft centre line of the shaft centre line of mantle (2) and excentric sleeve (4) is consistent.Having overcome existing gyratory crusher is to guarantee that main shaft is not fractureed, and has to reduce the defective of rotating speed.Fixed awl (1) and mantle (2) be surperficial all to stud with the liner plate that manganese steel or other high-abrasive materials are made.When the variation of the raw meal particle size that enters disintegrating machine, or the fineness of product needs to change, and can adapt to by regulating the discharging opening size, and this example adopts the hydraulic pressure adjustment, makes to decide the upper and lower mobile needed size that reaches of awl.
The utility model has changed the force-bearing situation of main shaft, the safety coefficient of main shaft greatly improves, excentric sleeve more existing excentric sleeve on length, circumference, overall weight greatly reduces, therefore can improve rotating speed 30% by existing gyratory crusher, thereby make output improve more than 50%, and the sphere bearing shell is provided with rationally, and convenient disassembly is convenient to maintenance.
