Abstract
The utility model relates to a crusher roller which belongs to an important component of a crusher. The crusher roller is composed of a cylinder and crushing teeth, wherein the crushing teeth are fixed on the cylinder to form an integral body. The cylinder and the crushing teeth are composed of an outer layer and an inner layer and are in the composite forming double-layer structure. The utility model has the advantages of high strength of crushing teeth, wear resistant, long service life, easy production, short production cycle, low cost, uniform distribution of crushing teeth on the cylinder, small tolerance, high work efficiency of the complete machine, etc.
Description
Affiliated technical field
The utility model relates to an a kind of vitals of disintegrating machine, with the disintegrating machine discaling roll of steel alloy composite casting.
Background technology
At present, known disintegrating machine discaling roll is to adopt cylinder and crushing teeth casting respectively, by welding manner crushing teeth is fixed on the cylinder on request.Crushing teeth requires to be evenly distributed on the cylinder, but manually-operated is easy to occur deviation, directly influences the operating efficiency of complete machine.The discaling roll of disintegrating machine is the main working parts of disintegrating machine, requirement has higher tolerance fit, tooth to want fixation, mechanical strength height, anti-wear performance good, existing processing technology and general material are difficult to satisfy its requirement, in the complete machine operation process crushing teeth easy to wear, easily fall tooth, broken teeth, thereby reduced service life, and the manufacturing processed complex will pass through casting, car, mills, manually weld multiple working procedure, and fabrication cycle is long.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the utility model provides a kind of and has made simple, tooth and be evenly distributed, do not fall tooth, the disintegrating machine discaling roll of broken teeth, wear-resisting, long service life, good combination property not.
The technical scheme that its technical problem that solves the utility model adopts is: the disintegrating machine discaling roll is made of cylinder, crushing teeth, crushing teeth is fixed on the cylinder, cylinder and crushing teeth are one, and cylinder and crushing teeth constitute by outer and nexine, are the double-decker of composite molding.Skin is high strength, wear-resisting steel alloy, the cast steel that nexine is a good toughness, plasticity is good.
The utility model compared with prior art its beneficial effect is:
1, discaling roll is not needed reprocessing and welding, thereby is made simply by cylinder and the whole composite casting moulding of crushing teeth, and with short production cycle, production cost is low;
2, crushing teeth has higher intensity and hardness, and is wear-resisting, do not fall tooth, not broken teeth, long service life;
3, crushing teeth is evenly distributed on cylinder, and tolerance is little, and complete machine is easily assembled, and runs well, and improves the operating efficiency of complete machine greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model cut-away view
Among the figure: 1, cylinder, 2, crushing teeth, 3, skin, 4, nexine.
The specific embodiment
In Fig. 1, the disintegrating machine discaling roll is to be made of cylinder (1) and the crushing teeth (2) that is fixed on the cylinder (1), and cylinder and crushing teeth are one.
In Fig. 2, cylinder (1) and crushing teeth (2) are to adopt the composite casting moulding, do not need with manually crushing teeth being welded on the cylinder, thereby tolerance are little again.As shown in Figure 2, cylinder (1) and crushing teeth (2) double-decker that skin (3) and nexine (4) constitute of all serving as reasons, it is composite molding, its skin (3) is high strength, wear-resisting steel alloy, nexine (4) is the cast steel of people's good toughness, have not only easily machine-shaping but also intensity height, wear-resisting characteristics, improved service life of the present utility model greatly.
Claims (1)
1, a kind of disintegrating machine discaling roll, comprise that cylinder, crushing teeth, crushing teeth are fixed on the cylinder, is characterized in that: cylinder and crushing teeth are one, cylinder and crushing teeth constitute by outer and nexine, are the double-decker of composite molding.
