Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described further.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
nullAs shown in Figure 2，A kind of thrust bearing for gyratory crusher，Including the upper thrust button 1 being arranged on below mantle main shaft、Upper permanent magnetic iron pole 2 and upper snap ring 3，It is arranged on the lower thrust button 4 above oil cylinder piston、Lower permanent magnetic iron pole 5 and lower snap ring 6，Described upper thrust button 1、Middle thrust button 7 it is additionally provided with between lower thrust button 4，It is characterized in that: described upper thrust button 1 is fixed on the lower end spindle nose of mantle main shaft，Described upper permanent magnetic iron pole 2 is embedded in the inside of upper thrust button 1 lower surface by upper snap ring 3，Described lower thrust button 4 is fixed on the top of oil cylinder piston，Described lower permanent magnetic iron pole 5 is embedded in the inside of lower thrust button 4 upper surface by lower snap ring 6，Described middle thrust button 7 is arranged on the lower surface of thrust button 1、Between lower thrust button 4 upper surface，Described upper thrust button 1、Middle thrust button 7、The contact surface of lower thrust button 4 is connected by convex-concave structure，The lower surface of described upper thrust button 1 is the first protrudent sphere lower surface，The upper surface of described middle thrust button 7 is the first concave sphere upper surface，The upper surface of described lower thrust button 4 is the second concave sphere upper surface，The lower surface of described middle thrust button 7 is the second concave sphere lower surface，Described first protrudent sphere lower surface、First concave sphere upper surface is connected，Described second concave sphere upper surface、Second concave sphere lower surface is connected，The magnetic pole of described upper permanent magnetic iron pole 2 lower surface is identical with the magnetic pole of lower permanent magnetic iron pole 5 upper surface，And it is hollow structure，It is easy to leakage of oil.
Described upper thrust button 1, middle thrust button 7, lower thrust button 4 all use the material that can not be magnetized to make, upper thrust button 1, lower thrust button 4 all use Cu alloy material to make, middle thrust button 7 uses macromolecular material to make, can effectively prevent from being magnetized by upper permanent magnetic iron pole 2, lower permanent magnetic iron pole 5, affect using effect.
Described middle thrust button 7, the middle part of lower thrust button 4 are hollow structure, and hollow structure is oilhole 8, the fascia edge of described middle thrust button 7 is distributed multiple oil duct 9 being connected with oilhole 8, the lower surface of upper thrust button 1, the upper surface of lower thrust button 4 are equipped with oil groove, when lubricating oil flows into from oil cylinder piston, by the oilhole on thrust bearing, finally flowed out by oil groove and oil duct.
Operation principle for the thrust bearing of gyratory crusher of the present utility model is as follows, owing to upper thrust button is identical with the magnetic pole of permanent magnetic iron pole opposite face in lower thrust button, so having repulsive force between the two, when motion of main shaft, thrust bearing, while supporting mantle main shaft, has relative motion between the thrust button contact surface of upper, middle and lower, cause the abrasion of material, reach to reduce the effect of material abrasion, extended the replacement cycle of thrust bearing, reduce complete machine use cost；And, there is oil groove on upper and lower push-plate surface, has oilhole in the middle part of lower thrust button and middle thrust button, when lubricating oil flows into from oil cylinder piston, by the oilhole on thrust bearing, is finally flowed out by oil groove and oil duct.When abrasion reduces, its scrap reduces, alleviates the burden of complete machine lubricating system, thus reduce the replacing number of times of filter element, when the thrust button of thrust bearing needs to change, its upper and lower permanent magnetic iron pole can retain, it is directly installed in new thrust button, reduces its use cost further.
The installation diagram of the thrust bearing for gyratory crusher of the present utility model, as shown in Fig. 3, Fig. 4 and Fig. 5, it is high that efficient cone crusher rotating speed compares traditional round conic crusher, when power source drives eccentric bushing 10 to rotate with higher rotating speed, mantle main shaft 12 swing the most therewith carries out crushing operation, and it is different according to operating mode difference demand, oil cylinder is supported by thrust bearing and promotes mantle assembly to move up and down, going up thrust button 1 among these to be fixed with mantle main shaft 12 by fixing bolt 13, lower thrust button 4 is fixed with oil cylinder piston 11 by alignment pin 14；Middle thrust button 7 is between upper thrust button 1 and lower thrust button 4, and with both male-female, the magnetic pole of upper permanent magnetic iron pole 2 lower surface is identical with the magnetic pole of lower permanent magnetic iron pole 5 upper surface, when mantle main shaft 12 moves, thrust bearing upper, in, between lower thrust button three, there is relative displacement, the two sides magnetic pole relative with lower permanent magnetic iron pole 5 due to upper permanent magnetic iron pole 2 is identical, there is repulsive force between the two, it is embodied in the friction force reduction that thrust button 1 leads between lower thrust button 4, abrasion reduces, while complete machine runs, lubricating system is also through the oilhole A press-in lubricating oil of oil cylinder piston 11, flow through the oilhole on lower thrust button 4 and lower permanent magnetism pole, oilhole on thrust button 7 in entrance, eventually pass, oil duct in the oil groove on lower thrust button surface and middle thrust button flows out.In whole cyclic process, lubricating oil takes away the scrap that thrust bearing wears away, it is to avoid the secondary abrasion that scrap causes, and, after in the unit interval, abrasion reduces, the scrap that lubricating oil filter element filters reduces therewith, and its replacement cycle extends accordingly, and complete machine use cost reduces.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
