Abstract
A kind of tooth nested structure of rod-toothed crusher, comprise the arc tooth be arranged on discaling roll, be provided with trapezoidal internal tooth in the mounting groove of described arc tooth, two trapezoidal inclined planes of trapezoidal internal tooth and two sidewalls of mounting groove form interference fit, and are bolted clamping.The utility model by arranging trapezoidal internal tooth in the mounting groove of arc tooth, thus make arc tooth become box tooth cover, improve the bulk strength of tooth, increase wear-resisting area, and trapezoidal internal tooth and mounting groove in use form interference fit, the ability of its anti-axial force also improves greatly, relative to overall segmented toothing, service efficiency of the present utility model is also higher.
Description
Technical field
The utility model relates to the rod-toothed crusher in mining machinery field, specifically a kind of tooth nested structure of rod-toothed crusher.
Background technology
At present, widely used rod-toothed crusher on market, its wear-resisting teeth portion mostly is overall segmentation tooth and arcuate tooth (see accompanying drawing 2), for overall segmentation tooth, exactly multiple axle sleeve and segmentation space of teeth are arranged on main shaft, complicated operation, the part accuracy of manufacture requires higher, whole teeth portion axially can not bear larger power, and when after teeth portion wearing and tearing, changes quite trouble, the segmentation tooth that need not change and axle sleeve is needed also to remove, cause unnecessary workload, for large-scale rod-toothed crusher, this overall segmentation tooth lifting also bothers very much.
Another kind of arcuate toothing (see accompanying drawing 3), be that an arcuate tooth cover is fixed on discaling roll, owing to being arcuate, it is poor as wearing piece globality, and intensity is bad, in use also often occurs crack conditions, reduces service efficiency.
Utility model content
For solving the problem that in prior art, arc toothing globality is poor, intensity is low, the utility model provides a kind of tooth nested structure of rod-toothed crusher, with the reliability of the intensity and use that improve tooth cover.
The utility model is the technical scheme solving the problems of the technologies described above employing: a kind of tooth nested structure of rod-toothed crusher, comprise the arc tooth be arranged on discaling roll, trapezoidal internal tooth is provided with in the mounting groove of described arc tooth, two trapezoidal inclined planes of trapezoidal internal tooth and two sidewalls of mounting groove form interference fit, and are bolted clamping.
The two side that described mounting groove is relative is the inclined-plane shunk bottom mounting groove, and slide clamping on the two side of mounting groove for two inclined-planes of trapezoidal internal tooth, forms interference fit.
Be respectively arranged with the chuck of evagination bottom two trapezoidal inclined planes of described trapezoidal internal tooth, two chuck match with the two side arc tooth being formed mounting groove respectively.
During this use is novel, the mounting groove of arc tooth and the trapezoidal inclined plane automatic capturing in the course of the work of trapezoidal internal tooth, reach a kind of interference fit state, avoids rocking during axially loaded;
This use the most outstanding novel feature is exactly the mounting groove of arc tooth and the interference fit of trapezoidal internal tooth, relative to single arcuate tooth, adopts trapezoidal internal tooth to couple together the neutral before and after arcuate, forms the box closed, improves the intensity of resistance to roll flute; The trapezoidal inclined plane of trapezoidal internal tooth, allows the mounting groove of arc tooth coordinate closely with internal tooth automatic capturing, increases axial carrying capacity simultaneously.
Beneficial effect: the utility model by arranging trapezoidal internal tooth in the mounting groove of arc tooth, thus make arc tooth become box tooth cover, improve the bulk strength of tooth, increase wear-resisting area, and trapezoidal internal tooth and mounting groove in use form interference fit, the ability of its anti-axial force also improves greatly, relative to overall segmented toothing, service efficiency of the present utility model is also higher.

Fig. 3 is arc toothing in prior art;
Reference numeral: 1, arc tooth, 2, mounting groove, 3, trapezoidal internal tooth, 4, bolt, 5, chuck.
Detailed description of the invention
As shown in the figure, a tooth nested structure for rod-toothed crusher, comprises the arc tooth 1 be arranged on discaling roll, is provided with trapezoidal internal tooth 3 in the mounting groove 2 of described arc tooth 1, two trapezoidal inclined planes of trapezoidal internal tooth 3 and two sidewalls of mounting groove 2 form interference fit, and by the fixing clamping of bolt 4.
Be more than basic embodiment of the present utility model, can do on above basis and further improve or limit:
If, the two side that described mounting groove 2 is relative is the inclined-plane shunk bottom mounting groove 2, slides clamping on the two side of mounting groove 2 for two inclined-planes of trapezoidal internal tooth 3, formation interference fit;
And for example, chuck 5, two chuck 5 being respectively arranged with evagination bottom two trapezoidal inclined planes of described trapezoidal internal tooth 3 match with the two side arc tooth 1 being formed mounting groove 2 respectively.
The mounting groove 2 of arc tooth 1, when assembling, is stuck on trapezoidal internal tooth 3 by the utility model, both is struck tight in advance, form interference fit by external force, and then both is combined fixing with bolt 4.
