Description

A kind of crusher rotor
Technical field
The invention belongs to crushing mechanism technical field, particularly a kind of crusher rotor.
Background technology
Disintegrating machine is widely used in the various fields such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.Wherein, hammer mill is directly the disintegrating machine that the material of 600-1800 millimeter is crushed to less than 25 or 25 millimeters by maximum particle size; The tup that rotor of hammer type crusher of the prior art generally comprises main shaft, is arranged at the hammer dish on main shaft and is arranged between adjacent hammer dish, during disintegrating machine work, High Rotation Speed made by driven by motor main shaft, material enters in disintegrating machine chamber uniformly, the pivotal tup of high speed impacts, shearing splitting material, until material is broken.
Crusher rotor as the core component of disintegrating machine, its force-bearing situation very severe, especially hammer dish and tup, during the larger material impact hammer dish of volume, not only can cause the heavy wear of hammer dish outer rim, and hammer dish also can produce distortion or axial twist, easily causes main shaft to rupture; In addition, when the pivotal tup impact of high speed, shearing material, the stressed hammer axle fracture easily causing very greatly location tup; And existing crusher rotor, only adopt flat key mode to lock between main shaft and hammer dish to be integrated, produce impact stress because tup hits and answer moment to imitate greatly, key, keyway can be made when easily causing flat key to be fixed on main shaft to produce distortion, cause that axial location is unreliable, gap is large, cause complete machine oscillation, noise is large.
Above-mentioned weak point has had a strong impact on the normal operation of disintegrating machine, and cause frequent maintenance and change parts, impact is produced, and brings huge economic loss to manufacturing enterprise.
Summary of the invention
The object of this invention is to provide a kind of reasonable in design, structural strength large, be convenient to repair demolition, and anti-wear performance and the high crusher rotor of impact resistance, efficiently solves above-mentioned background technology Problems existing.
The technical scheme that the present invention adopts for achieving the above object is: a kind of crusher rotor, comprise hammer dish main shaft and spacer sleeve and be located at multiple hammer dishes outside described hammer dish main shaft, described multiple hammer dish is fixed on hammer dish main shaft by flat key, tup is connected with by hammer axle between described adjacent hammer dish, the position annular array of the outer edge of described each hammer dish offers hammer axle sleeve hole, the hammer axle sleeve passed for hammer axle is positioned with in each hammer axle sleeve hole, the two ends end face of the hammer axle sleeve in each hammer axle sleeve hole protrudes the two ends end face with the hammer dish of its assembling respectively, also reinforcing flange is arranged with respectively outside the hammer axle sleeve protruding each hammer dish two ends end face, described hammer axle through each hammer dish hammer axle sleeve and tup is positioned at adjacent hammer dish, and tup can around hammer axle rotate.
Further technical scheme of the present invention is: also comprise thrust axis and pulling force axle sleeve, the position of the outer edge of described hammer dish also annular array offer for for thrust axis cover through thrust axis trepanning, between two hammer axle sleeve holes that thrust axis trepanning is adjacent on hammer dish, pulling force axle sleeve is positioned in described thrust axis trepanning and the two ends end face of every bar pulling force axle sleeve protrudes hammer dish two ends end face respectively, and the pulling force axle sleeve in adjacent two hammer dishes compresses mutually, described thrust axis is through the pulling force axle sleeve of each hammer dish; The pulling force axle sleeve outer circumferential surface heap of described protrusion hammer dish end face is welded with wearing layer.
Further technical scheme of the present invention is: described hammer axle is segmentation structure, comprises hammer axle I and hammer axle II; The outer circumferential surface of described hammer dish and the position of the outer edge of hammer dish both sides end face are piled respectively and are welded with wearing layer; The outer circumferential surface heap of described reinforcing flange is welded with wearing layer.
A kind of crusher rotor of the present invention has following beneficial effect:
1, a kind of crusher rotor of the present invention, by hammer axle sleeve, hammer axle is positioned on hammer dish, thus tup is positioned between two adjacent hammer dishes, outside with hour hammer axle sleeve is also arranged with reinforcing flange, adopts such structure, and material can not direct jump bit axle, not to be hit wearing and tearing by hammer axle sleeve and reinforcing flange protection hammer axle, optimize the intensity of hammer axle, hammer axle stressing conditions improves, and hammer axle is not easy to wear, fracture; The present invention all piles and is welded with wearing layer on each member outside face contacted with material in addition, improves the abrasion condition of parts, greatly increases anti-wear performance of the present invention and impact resistance;
2, compared to prior art, the present invention adds thrust axis between adjacent hammer axle, all hammer dishes connect as a whole through all hammer dishes by thrust axis, are distributed on each hammer dish with making the uniform force of crusher rotor of the present invention when broken material, improve the force-bearing situation of hammer dish; In addition, when one of them flat key lost efficacy, when this hammer dish and hammer dish main shaft come off, be also connected with other hammer dishes by this thrust axis, prevent hammer dish from rocking or radial rotating in the axis of hammer dish main shaft; Meanwhile, when larger material impact hammer dish end face, owing to there being the effect of thrust axis, hammer dish will cause hammer dish main shaft to rupture because of generation distortion or axial twist, effectively protects hammer dish main shaft;
3, the tup in the present invention is positioned between adjacent hammer dish by hammer axle, and tup can rotate around hammer axle, when running into the not breakable material that volume is comparatively large or hardness is higher, tup can be screwed in the inner space between two hammer dishes, formed and automatically hide, protect tup and hammer axle, extend the service life of tup and hammer axle;
4, hammer axle of the present invention adopts segmentation structure, and hammer axle is divided into two sections, and assembly difficulty is little, raises the efficiency; In addition, because the force-bearing situation of tup and hammer axle is severe, the rear hammer dish of long-time use, tup and hammer axle all can produce distortion, when needs detachable maintaining, all-in-one-piece hammer shaft length is comparatively large, and after distortion, dismounting is very difficult, hammer axle is divided into two sections by the present invention, reduce the length of single hammer axle, be convenient to detachable maintaining, improve operating efficiency.
Below in conjunction with drawings and Examples, a kind of crusher rotor of the present invention is further described.
