The specific embodiment
Technical scheme in the embodiment of the present invention is carried out to clear, complete description below.
The invention provides a kind of gyratory crusher, comprise mainframe 13, mantle 1, movable main shaft 2, fixed main shaft 12 and eccentric bushing 4.Power transmission shaft 9 is arranged in drive shaft mount 8 by (or rolling) bearing that slides, and power transmission shaft 9 one end are fixed with the first conical gear 11, and the other end is fixed with belt pulley 10(or shaft coupling).The first conical gear 11 engages with the second conical gear 14 being fixed on eccentric bushing 4.The first rolling bearing 6 is installed in the bottom of eccentric bushing 4 inner chambers, and the second rolling bearing 3 is installed on top.Eccentric bushing 4 was both set on fixed main shaft 12 by the first rolling bearing 6 that is positioned at eccentric bushing 4 bottoms, was located on mainframe 13 again by the first thrust bearing 7.Fixed main shaft 12 is vertically fixedly installed in the central authorities of mainframe 13.Mantle 1 comprises the chamber under shed, and mantle 1 also comprises the movable main shaft 2 and the spherical support portion 18 that are fixedly installed in mantle 1 chamber, and spherical support portion 18 is positioned at the bottom of movable main shaft 2.Axis, the axis of mantle 1 and the centre of sphere of spherical support portion 18 of movable main shaft 2 are on same straight line.Mantle 1 is located on the spherical bearing watts 19 that is fixedly installed on fixed main shaft 12 tops by spherical support portion 18, and the external cylindrical surface of movable main shaft 2 contacts with the second rolling bearing 3 that is arranged on eccentric bushing 4 inner chamber tops.The axis of the axis of the first rolling bearing 6 and the second rolling bearing 3 intersects with a special angle, and therefore, the axis of movable main shaft (2) and the axis of fixed main shaft 12 also intersect with a special angle.
The second thrust bearing 5 is positioned on the shoulder in eccentric bushing 4 outsides, and mantle 1 also comprises the thrust bearing contact site 20 that is positioned at the second thrust bearing 5 tops.The rolled mortar wall 17 coordinating with mantle 1 is fixedly mounted in adjusting sleeve 16.Adjusting sleeve 16 is combined with the internal thread of splicing sleeve 15 by external screw thread.Splicing sleeve 15 is located on mainframe 13, and the part contact-making surface contacting with mainframe 13 is the conical surface.
In above-mentioned gyratory crusher, mantle 1 is located in by spherical support portion 18 on the spherical bearing watts 19 on fixed main shaft 12 tops, and the centre of sphere of spherical bearing watts 19 is the hitch point of mantle 1.By means of the second rolling bearing 3 of eccentric bushing 4, the movable main shaft 2 in mantle 1 forms the second rolling movement pair with second rolling bearing 3 on the inner chamber top of eccentric bushing 4; By means of the first rolling bearing 6 of eccentric bushing 4, the first rolling bearing 6 and the face of cylinder of fixed main shaft 12 of the inner chamber bottom of eccentric bushing 4 form the first rolling movement pair.Eccentric bushing 4 is located on mainframe 13 by the first thrust bearing 7, also contacts with movable main shaft 2 with fixed main shaft 12 with the second rolling bearing 3 by the first rolling bearing 6.
When eccentric bushing 4 rotates, mantle 1 does swing campaign take hitch point as the heart around the axis through spherical bearing watt 19 centre ofs sphere, realizes the crushing action of disintegrating machine.The design of gyratory crusher of the present invention has increased the hunting range of mantle 1, has strengthened the arm of force of eccentric bushing 4 to mantle 1 application of force, thereby improves disintegrating machine energy utilization rate.
Before use, the spherical support portion 18 of mantle 1 and spherical bearing watts 19 contacts, and thrust bearing contact site 20 does not contact with the second thrust bearing 5, or the second thrust bearing 5 is not subject to the effect of thrust bearing contact site 20 pressure.In use, before the spherical bearing watt a small amount of wearing and tearing of 19 appearance, spherical support portion 18 and spherical bearing watts 19 both born whole vertical stress components and the part of horizontal component of the crushing force that acts on mantle 1, mantle 1 driving while simultaneously also playing a part to prevent zero load, the second thrust bearing 5 is not subject to the effect of thrust bearing contact site 20 pressure equally.Spherical bearing watts 19 has after a small amount of wearing and tearing, the thrust bearing contact site 20 of mantle 1 starts to contact with the second thrust bearing 5, spherical support portion 18 and spherical bearing watts 19, the second thrust bearing 5 and the first thrust bearing 7 all will be shared a part of crushing force vertical stress component from mantle 1, between spherical support portion 18 and spherical bearing watts 19, frictional resistance reduces, spherical bearing watts 19 wearing and tearing slow down, but still mantle 1 driving can stop gyratory crusher unloaded time.
In addition, the axes intersect of the axis of movable main shaft 2 and fixed main shaft 12 fork, the centre of sphere of the intersection point of two axis and spherical bearing on fixed main shaft 12 watts 19 overlaps.Mantle 1 is located in by moving spherical support portion 18 on the spherical bearing watts 19 on fixed main shaft 12 tops, and the centre of sphere of spherical bearing watts 19 is the hitch point of mantle (1).
In sum, gyratory crusher of the present invention can reduce mechanical loss and unit crushed product energy consumption, improves disintegrating machine energy utilization rate; Improve eccentric bushing rotating speed, increase disintegrating machine production capacity, improve the degree of particulate in crushed product stone shape and raising crushed product; Improve disintegrating machine operating reliability and equipment operation rate.
Obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
