Description

A kind of gyratory crusher upper recess surface thrust mechanism
[technical field]
The utility model relates to the technical field of gyratory crusher, particularly a kind of technical field of thrust mechanism.
[background technology]
Gyratory crusher is applicable to metallurgy, builds, builds the road, the fragmentation of chemistry and silicate industry Raw, vary in size according to the difference of smashing principle and magnanimity product particle, be divided into again a lot of model, disintegrating machine is widely used in numerous departments such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry, cone crushing ratio is large, efficiency is high, energy consumption is low, product granularity is even, broken and various ore in small, broken bits in being applicable to, rock.The structural design of the crushing head mechanism in gyratory crusher conventional is at present reasonable not, the inadequate science of layout, and the reliability in transmission process is poor, and the wearing and tearing in running are comparatively serious, shorten the service life of equipment.
Thrust mechanism is one of key component of gyratory crusher, its Main Function is supporting mantle group, has spinfunction, in the middle of prior art, adopt the pad number regulating thrust plate bottom, carry out the upper-lower position of eccentric sleeves, stressed very large due to eccentric bushing, therefore the requirement on machining accuracy of each thrust plate is high, because each thrust plate end face is a plane, thus the frictional force between thrust plate is very large, and each thrust plate does not have sufficient lubricant method, is easy to wearing and tearing.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of gyratory crusher upper recess surface thrust mechanism, adopts spherical bearing group, strengthens the lubrication between thrust plate, can reduce the frictional resistance between thrust plate.
For achieving the above object, the utility model proposes a kind of gyratory crusher upper recess surface thrust mechanism, comprise main shaft, contiguous block, upper thrust plate, middle thrust plate, lower thrust plate, piston body, described middle thrust plate upper surface is the arc structure of fovea superior, lower surface is planar structure, middle thrust plate upper end is provided with thrust plate, described upper thrust plate lower surface is lower convex arc structure, contiguous block is installed in upper thrust plate upper end, described contiguous block upper end is connected with main shaft, described lower thrust plate is installed on the bottom of middle thrust plate, described lower thrust plate lower end is connected with piston body.
As preferably, described contiguous block upper and lower surface is respectively equipped with bulge-structure, and contiguous block is coordinated with main shaft and upper thrust plate respectively by bulge-structure to be installed.
As preferably, have locating hole, be provided with alignment pin in locating hole in described piston body, lower thrust plate to be coordinated with piston body by alignment pin to be installed.
As preferably, described upper thrust plate and middle thrust plate coordinate the surface of installing to be provided with groove, and described lower thrust plate and middle thrust plate coordinate the surface of installing to be provided with groove.
The beneficial effects of the utility model: the utility model is by being arranged to spherical structure by the lower surface of the upper surface of middle thrust plate and upper thrust plate, and projection and groove are set on sphere, be provided with the profit oilhole of apply oil on the piston body simultaneously, when main shaft runs up, the frictional resistance between each thrust plate contact surface can be reduced greatly, reduce wearing and tearing greatly, improve service life.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the main TV structure figure of a kind of gyratory crusher of the utility model upper recess surface thrust mechanism;
Fig. 2 is the structural representation of the utility model groove.
[detailed description of the invention]
Consult Fig. 1, Fig. 2, a kind of gyratory crusher upper recess surface thrust mechanism of the utility model, comprise main shaft 1, contiguous block 2, upper thrust plate 3, middle thrust plate 4, lower thrust plate 5, piston body 6, described middle thrust plate 4 upper surface is the arc structure of fovea superior, lower surface is planar structure, middle thrust plate 4 upper end is provided with thrust plate 3, described upper thrust plate 3 lower surface is lower convex arc structure, contiguous block 2 is installed in upper thrust plate 3 upper end, described contiguous block 2 upper end is connected with main shaft 1, described lower thrust plate 5 is installed on the bottom of middle thrust plate 4, described lower thrust plate 5 lower end is connected with piston body 6, described contiguous block 2 upper and lower surface is respectively equipped with bulge-structure 21, contiguous block 2 is connected with main shaft 1 and upper thrust plate 3 respectively by bulge-structure 21, locating hole is had in described piston body 6, alignment pin 7 is installed in locating hole, lower thrust plate 5 is coordinated with piston body 6 by alignment pin 7 to be installed, described upper thrust plate 3 and middle thrust plate 4 coordinate the surface of installing to be provided with groove 8, described lower thrust plate 5 and middle thrust plate 4 coordinate the surface of installing to be provided with groove 8.
Utility model works process:
A kind of gyratory crusher of the utility model with upper recess surface thrust mechanism in the course of the work, piston body 6 is by upper thrust plate 3, middle thrust plate 4 and lower thrust plate 5 carry out supporting spindle 1, middle thrust plate 4 upper surface is the arc structure of fovea superior, upper thrust plate 3 lower surface be mated is lower convex arc structure, during work, relative sliding can be there is between upper thrust plate 3 and middle thrust plate 4, relative slip can be there is between middle thrust plate 4 and lower thrust plate 5, middle thrust plate 4 upper recess surface is provided with bulge-structure, described upper thrust plate 3 is provided with the groove corresponding with bulge-structure, these projections and groove can increase oil storage capacity, therefore the frictional force between thrust plate is very large, piston body 6 is provided with profit oilhole, lubricating oil can flow into gap between each thrust plate by profit oilhole, groove 8 be arranged so that there is between each thrust plate certain storage lubricating oil ability, so that better relative sliding, when main shaft runs up, the reliability run well between each thrust plate can be ensured.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
