Background technology
Eccentric bushing is one of parts important in crusher system, and it is bearing the transmission of power work of tcrude ore being carried out to coarse crushing, under actual condition, is bearing the periodicity effect of the alternate stresses such as great impulsive force, shearing force and extruding force.It is work period, the stress of complexity and severe working environment frequently, has determined that eccentric bushing must have higher crudy.Current eccentric bushing comprises cast steel substrate, at described cast steel substrate upper babbit inner sleeve and local overcoat, in order to improve the bond strength of babbit and cast steel substrate, a plurality of through holes on cast steel substrate jacket wall, have been disposed radially, on wall, be provided with a plurality of cell bodies within it, object is to improve the bond strength of babbit and cast steel substrate, although increased cost like this on manufacturing, but still can not solve eccentric bushing rapid failure problem, general normal service life only has 6 months even less than one month.Eccentric bushing initial failure is mainly because coming off appears in babbit layer, crack, cannot meet instructions for use.This eccentric bushing not only service life short, and maintenance difficult, present repair mode is all eccentric bushing to be returned to manufactory again pour into a mould.Because eccentric bushing volume is large, weight is large, such maintenance cost is very high, as length is so repaired to an expense at 13～160,000 yuan at the eccentric bushing of 1.8 meters, and it is still not long to reuse the life-span, has so just greatly increased the production cost of equipment use enterprise.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, and long service life is convenient to repeat the eccentric sleeve for cracker that maintenance is used.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of eccentric sleeve for cracker, comprise columnar cast steel substrate, described cast steel substrate comprises inner and outer wall, described inner and outer wall is the center of circle eccentric setting of place circle separately, it is characterized in that, the inwall middle part of described cast steel substrate is provided with annular compound layer, and outer wall is provided with semicircular arc composite bed, and described composite bed is formed by copper alloy built-up welding in described inwall or outer wall surface.
The beneficial effects of the utility model are: the one, and the structure of cast steel substrate is compared with the cast steel substrate of prior art, without numerous through holes and groove are set, manufacture craft is greatly simplified; The 2nd, the inside and outside wall solder bond of copper alloy composite bed and described cast steel substrate, belongs to metallurgical binding, compares in conjunction with physical bond in other words with cast between the babbit of prior art and cast steel substrate, and its adhesive strength improves a lot; The 3rd, eccentric bushing long service life, generally surpasses existing product more than one times; The 4th, when there are wearing and tearing, be convenient to repeatedly on-the-spot local reparation, its repairing efficiency is short, and cost is low.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described annular compound floor height goes out described inwall, at the two ends up and down of described annular compound layer, forms lower convex platform and convex platform.
Adopt the beneficial effect of above-mentioned further scheme to be, annular compound layer is for the main shaft socket with disintegrating machine, and bottom non-working surface retains the larger more convenient device assembles in gap thereon.
Further, it is semi arch summit that described semicircular arc composite bed be take the wall thickness maximum point of described cast steel substrate, and the radian of described semicircular arc composite bed is greater than 270 °.
Adopt the beneficial effect of above-mentioned further scheme to be, this semicircular arc composite bed is arranged on the stressed side of disintegrating machine off-centre operation, economizes on material.
Further, on described cast steel substrate, be also provided with a plurality of oil filler points.
Adopting the beneficial effect of above-mentioned further scheme is to be convenient to charging-up lubricant oil.
Further, described copper alloy is aluminium bronze.
Adopt the beneficial effect of above-mentioned further scheme to be, aluminium bronze Qiang Du Gao ﹐ wearability and corrosion resistance are good, are more suitable for making composite bed on eccentric bushing.
Further, the top of described cast steel substrate is provided with cannelure, and the top of described cast steel substrate is also provided with upper shoulder.
Adopt the beneficial effect of above-mentioned further scheme to be, be convenient to install.
