Abstract
The utility model relates to mining equiment field, particularly relates to a kind of mantle main shaft group of gyratory crusher.A mantle main shaft group for gyratory crusher, comprises main shaft, and is set in the movable cone outside main shaft, and is set in the mantle liner plate outside movable cone; Described movable cone is the large taper type of the little lower end diameter of upper end diameter, closely offset between the lower end inside face of mantle liner plate and the lower end outside face of movable cone, the mantle groove of filling epoxy resin is configured between the upper end medial surface of mantle liner plate and the upper end lateral surface of movable cone, main shaft above movable cone has been threaded locking nut, locking nut axial location mantle liner plate.The mantle main shaft group of this gyratory crusher, adopts three kinds of connected modes to limit the axial and circumferential of mantle liner plate respectively, makes to be connected firmly between mantle liner plate and movable cone, good stability.
Description
Technical field
The utility model relates to mining equiment field, particularly relates to a kind of mantle main shaft group of gyratory crusher.
Background technology
Gyratory crusher is a kind of mining machinery for broken building stones, and its principle is that the mantle main shaft group and frame of being rotated by swing determine the mutual attrition crushing building stones of cone.Wherein, the mantle main shaft group of gyratory crusher includes main shaft, and is set in the movable cone on main shaft, and is set in the mantle liner plate outside movable cone; During broken building stones, mantle liner plate directly contacts with building stones, extrudes, therefore mantle liner plate arrange very crucial.But the connection between the mantle liner plate of existing gyratory crusher and movable cone is insecure, mantle liner plate easily loosens, and there is potential safety hazard.
Summary of the invention
In order to solve the problem, the purpose of this utility model is the mantle main shaft group providing a kind of gyratory crusher.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A mantle main shaft group for gyratory crusher, comprises main shaft, and is set in the movable cone outside main shaft, and is set in the mantle liner plate outside movable cone; Described movable cone is the large taper type of the little lower end diameter of upper end diameter, closely offset between the lower end inside face of mantle liner plate and the lower end outside face of movable cone, the mantle groove of filling epoxy resin is configured between the upper end medial surface of mantle liner plate and the upper end lateral surface of movable cone, main shaft above movable cone has been threaded locking nut, locking nut axial location mantle liner plate.
As preferably, the mid diameter of main shaft is greater than its two ends diameter, and the axle center place of movable cone is provided with spindle hole, and movable cone is set in outside the middle part of main shaft.
As preferably, between locking nut and mantle liner plate, be provided with cut ring; During dismounting, can cut ring be cut off, thus be convenient to back out locking nut, dismounting mantle liner plate.
The utility model adopts technique scheme, and the mantle main shaft group of this gyratory crusher, adopts three kinds of connected modes to limit the axial and circumferential of mantle liner plate respectively, make to be connected firmly between mantle liner plate and movable cone, good stability; It is specifically: 1, and movable cone is the taper type that the little lower end diameter of upper end diameter is large, and taper fit between mantle liner plate and movable cone closely offsets between the lower end inside face of mantle liner plate and the lower end outside face of movable cone, thus restriction mantle liner plate down slides; 2, for filling epoxy resin in the mantle groove between mantle liner plate and movable cone, by epoxy resin, mantle liner plate and movable cone are clung, thus the slip in restriction mantle liner plate circumference; 3, main shaft is provided with locking nut, locking nut axial location mantle liner plate, thus restriction mantle liner plate up slides.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
The mantle main shaft group of a kind of gyratory crusher as shown in Figure 1 comprises main shaft 31, movable cone 32 and mantle liner plate 33; The mid diameter of main shaft 31 is greater than its two ends diameter, the taper type that movable cone 32 is large in the little lower end diameter of upper end diameter, and the axle center place of movable cone 32 is provided with spindle hole, and movable cone 32 is set in the outside in the middle part of main shaft 31.Described mantle liner plate 33 coning sleeve is located at the outside of movable cone 32, closely offset between the lower end inside face of mantle liner plate 33 and the lower end outside face of movable cone 32, the mantle groove 37 of filling epoxy resin is configured between the upper end medial surface of mantle liner plate 33 and the upper end lateral surface of movable cone 32, main shaft above movable cone 32 has also been threaded locking nut 38, locking nut 38 axial location mantle liner plate 33, is provided with cut ring 39 between the upper surface of locking nut 38 and mantle liner plate 33.
During installation, taper fit between mantle liner plate 33 and movable cone 32, restriction mantle liner plate 33 down slides; Filling epoxy resin in mantle groove 37 between mantle liner plate 33 and movable cone 32, is clung mantle liner plate and movable cone by epoxy resin, thus the slip in restriction mantle liner plate 33 circumference; Locking nut 38 pushes down the upper surface of mantle liner plate 33 by cut ring 39, and restriction mantle liner plate 33 up slides.Adopt above-mentioned three kinds of connected modes to limit the axial and circumferential of mantle liner plate respectively, make to be connected firmly between mantle liner plate and movable cone, good stability; Cut ring 39 can be cut off when mantle liner plate 33 changed by needs, back out locking nut 38, knock mantle liner plate 33 and itself and movable cone 32 are loosened, take off from main shaft 31 upper end.
Claims (3)
