Abstract
The utility model discloses a roller rotor for a single-roller crusher. The roller rotor comprises a gear crown and a wear-resistant layer, and is characterized in that the end face of the gear crown is in a trapezoid structure, the outer side of the gear crown is provided with a protective lining, the protective lining contacts with the wear-resistant layer, and the outer side of the wear-resistant layer is changed from arc transition to straight-line small-angle transition. The roller rotor improves wear-resistant property of the rotor, and prolongs service life.
Description
Technical field
The utility model relates to a kind of single roll crusher roller rotor, belongs to mechanical field.
Background technology
The working environment of metallurgy sintered single roll crusher rotor is very abominable, and generally all about 800 ℃, crushing hot sinter cake intensity is high for the environment temperature of running hours, and the thermal wear that under this ambient condition the single roll crusher rotor is caused is very serious.Repeatedly site inspection finds that the most serious position of wearing and tearing is the crown topmost, whole crown 1/3rd namely, and in former design 1/3rd places on crown top, the position of whole crown minimum just seems more obvious so wear and tear exactly, and the rotor crown does not design the water circulation cooling, so just greatly shortened the life cycle of rotor spare part, rotor can only use 9 months, had seriously restricted the continuous production of large production system, affected production efficiency.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of single roll crusher roller rotor, and crown has been carried out architecture advances, in the situation that guarantee that the crown bonding strength is substantially constant, the mother metal of crown is suitably dwindled, mother metal is changed profile, increased its anti-wear performance.
The technical solution adopted in the utility model is: a kind of single roll crusher roller rotor; comprise crown; wearing layer; it is characterized in that: the end face of described crown is trapezium structure; the crown outside is provided with the protection lining; the protection lining contacts with wearing layer, and the wearing layer outside changes to the transition of straight line low-angle by arc transition.
In such scheme, the thickness of described protection lining is 5 ~ 10mm.
In the utility model, change the dihedral working face of former crown into trapezoidal working face, increase the protection lining of 5-10mm thickness at the crown end face.Original wearing layer is arc transition, changes to the transition of straight line low-angle.That is to say, with the part protection lining filling that crown top dwindles, the protection lining is identical with the effect of wearing layer.After considering the prolongation in service life of crown, the corresponding reduction of roll shaft meeting in service life, so, simultaneously the roll shaft surface wear-resistant layer is also increased about 5-8mm.
When all high-abrasive materials carry out melting welding, note taking corresponding heat treatment safeguard measure, increase because of wearing layer thickness preventing, and cause that wearing layer integral body comes off when work.As: with melting welding high-abrasive material again after the mother metal heating; To be incubated certain hour after the melting welding, rear Slow cooling; Carry out temper, carry out Stress Release, crack performance is reduced.
The beneficial effect that the crusher's rollers rotor that the utility model provides brings: increase wearability, increase the service life.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of existing crusher's rollers rotor.
Fig. 2 is the structural representation of the utility model crusher's rollers rotor.
1 is crown among the figure, and 2 is wearing layer, and 3 are the protection lining.
The specific embodiment
Embodiment:
As shown in Figure 1, existing crusher's rollers rotor, crown 1 end face is the dihedral working face, wearing layer 2 is arc transition.
As shown in Figure 2, the crusher's rollers rotor that the utility model provides, the end face of crown 1 transform trapezium structure as, and crown 1 outside is provided with protection lining 3, and protection lining 3 contacts with wearing layer 2, and wearing layer 2 outsides change to the transition of straight line low-angle by arc transition.
The material of protection lining is identical with wearing layer in the utility model, has strengthened the wearability of device, has prolonged service life.
In May, 2012, Taiyuan Iron and Steel Co. three burnt 450m
2The single-roll crusher of sintering machine crown begins this device on probation, prepares it to be changed when the sintering machine system periodical repair according to the field apparatus operating position, has strengthened the wearability of device, has obtained good effect, has improved operating efficiency.
