Abstract
The utility model discloses a roll sleeve for roll shafts of roll type crushers, which comprises a roll sleeve body and a plurality of roll teeth positioned on the surface of the roll sleeve body, and the roll sleeve is characterized in that the tooth surface of each roll tooth is a curved surface transitionally formed by at least two cambered surfaces with different curvatures. The tip of each roll tooth is provided with a surfacing/embedded layer. The envelope angle Alpha of each roll tooth is 40 to 60 degrees, and the included angle Beta between each two neighboring roll teeth is 20 to 30 degrees; the envelope angles Alpha of all the roll teeth are equal or unequal, and the included angles Beta between the neighboring roll teeth are equal or unequal. Since the shape of the tooth surface of each roll tooth of the roll sleeve is formed by two or more cambered surfaces with different curvatures, the crushing and stripping force acting on material is more complex, and accords with the mechanism of the finally shaped surface of the abraded material, the material-crushing accuracy is increased, consequently, the material-crushing effect can reach optimum, and can accord with the final shape of the abraded surface, and therefore the roll sleeve is more suitable for roll type crushers. The abrasion resistance of the tips of the roll teeth can be enhanced by local surfacing, embedding or other techniques according to the different base materials of the roll sleeve.
Description
Technical field
The present invention relates to a kind of roll shaft roller shell, relate in particular to a kind of roller shell that is applicable to the kibbler roll roll shaft of grog fragmentation.
Background technology
The operation principle of kibbler roll is two rollers that rotate in opposite directions, by frictional force and gravity material is nipped in the crusher chamber, it is squeezed and ablation and reach crushing effect.In the process of broken material, directly the performance of the roller shell that contacts with material is the key factor that influences the disintegrating machine performance.The dissimilar tooth form of roller shell and processing technology all have very big influence for the service behaviour of disintegrating machine and the life-span of roller shell self.The roller shell roller tooth that comes into operation at present mostly is the roller tooth outline that the big or small transverse tooth thickness of the big transverse tooth thickness profile of tooth that adopts single curvature concave arc or single curvature concave arc combines.Though these roller shells also can be finished the material crushing operation, but can cause just material on the flank of tooth, to slide causing that crushing efficiency is not high, tooth surface abrasion is serious and big or small tooth unbalance stress in case run into bulk materials, the anti-heavily loaded ability of little transverse tooth thickness roller tooth is more weak and cause the problem that ruptures, reduce the roller shell bulk life time, had a strong impact on the work of disintegrating machine.
Summary of the invention
Technical problem solved by the invention is to overcome existing crusher's rollers to be enclosed within the crushing efficiency that occurs in the actual moving process low, the anti-heavily loaded ability of the serious and different little transverse tooth thickness gears that cause of transverse tooth thickness of tooth surface abrasion is more weak and cause the problem of its fracture, and a kind of simple in structure, roller shell of using reliable, that processing cost is low, maintenance workload is little a kind of kibbler roll roll shaft is provided.
A kind of roller shell of kibbler roll roll shaft comprises the roller shell body and is positioned at some roller teeth that roller shell overlaps the surface, it is characterized in that: the described roller tooth flank of tooth is the curved surface that the cambered surface transition of at least two different curvature forms.
Further prioritization scheme is: the crown of described roller tooth is provided with built-up welding/mosaic coating.
Further improvement project is: the envelope angle α of described roller tooth is 40 °～60 °, and the angle β of adjacent roller between cog is 20 °～30 °.The envelope angle α of each roller tooth equates or is unequal that the angle β of adjacent roller between cog equates or be unequal.
The present invention, roller tooth flank of tooth profile is made up of the cambered surface of two different curvature at least, make the power of the extruding that acts on the material and exploitation more complicated, meet the final molding face mechanism after material is denuded, improved the accuracy of the broken extruding of material, make the material crushing effect reach best, meet the wear surface net shape, be more suitable for being used for kibbler roll.Any measure can not taked according to the difference of roller shell basic material in roller tooth crown position, also can be by local built-up welding, the antiwear property that technology is strengthened the crown position such as inlay.
Description of drawings
Fig. 1 is the structural representation (square keyway) of the roller shell of kibbler roll roll shaft of the present invention.
Fig. 2 is the structural representation (square shaft) of the roller shell of kibbler roll roll shaft of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
What embodiment 1, Fig. 1 represented is the structural representation of the roller shell of kibbler roll roll shaft, and roller shell is that square key is connected with roll shaft.What Fig. 2 represented is the structural representation of the roller shell of kibbler roll roll shaft, and roller shell is that square shaft is connected with roll shaft.The roller shell of Fig. 1,2 described kibbler roll roll shafts, comprise roller shell body 3 and be positioned at some roller teeth 1 that roller shell overlaps the surface, the flank of tooth 5 of roller tooth is formed by the cambered surface transition of two different curvature, roller number of teeth amount is 4～6, the envelope angle α of roller tooth is 40 °～60 °, and the angle β of adjacent roller between cog is 20 °～30 °.Each roller tooth α angle of same roller shell can be identical with the β angle, also can be different.
Roller shell has been considered the roller tooth flank of tooth net shape that material forms in flank of tooth sliding friction when design, thereby determine rational flank of tooth moulding, give full play to ability and other positions of the flank of tooth of roller shell crown interlock material and assisted effect fixing, the grinding material, avoided material in the flank of tooth phenomenon of crusher chamber of to nip of sliding, make it more meet the mechanism of material extruding grinding, improve the accurate extruding when two rollers are worked in opposite directions, made the squeezing effect of grog reach best, improved productivity ratio.Consider that simultaneously roller shell crown stress is bigger in the process of material is nipped crusher chamber and broken material, and other positions of the flank of tooth help out, so the wearing and tearing of roller shell crown are also obvious.In order to improve material interlock ability, strengthen crown position antiwear property, thereby improve the roller shell life-span, in the roller shell process, go out built-up welding/mosaic coating 2 positions in the preprocessing of crown position, finally finish flank of tooth moulding by built-up welding/damascene process, by rational technological design, can make crown hardness reach 60～65HRC, when guaranteeing result of use, more reduced processing cost and difficulty, reduce maintenance cost, greatly improved production efficiency and economic results in society.The inner ring of this roller shell can be processed into square keyway 4(Fig. 1), connect with roll shaft by square key, also can directly be processed into square hole and connect (Fig. 2) with square shaft, two kinds of connecting modes are all low to positioning accuracy request, can guarantee to connect reliably easy installation and removal.
