Wear-resisting split roller shell of the present utility model, partly can dismantle wear-resistant block and carry out repairing or changing, easy to maintenance, laborsaving, its internal layer can be reused, cost-saving.
Read the following description for exemplary embodiment with reference to accompanying drawing, other property features of the present utility model and advantage will become clear.
Accompanying drawing explanation
To be incorporated in description and the accompanying drawing forming a part for description shows embodiment of the present utility model, and together with the description for explaining principle of the present utility model.In the drawings, similar Reference numeral is used for key element like representation class.Accompanying drawing in the following describes is embodiments more of the present utility model, instead of whole embodiment.For those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can be obtained according to these accompanying drawings.
Fig. 1 schematically illustrates the structural representation according to wear-resisting split roller shell of the present utility model.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined mutually.
Basic thought of the present utility model is to provide a kind of wear-resisting split roller shell, internal layer and outer two large divisions is counted by sheathed for wear resistant roll, skin is designed to again polylith split, every block split can change separately, change and repair in such use procedure, can be time saving and energy saving, and interior layer segment can be reused, save material, save cost.
Below in conjunction with accompanying drawing, the wear-resisting split roller shell that the utility model provides is described in detail.
Fig. 1 shows the structural representation of wear-resisting split roller shell of the present utility model.With reference to shown in Fig. 1, this wear-resisting split roller shell comprises internal layer 1, polylith wear-resistant block 2, multiple fastening bolt 3.Wherein, the structure of internal layer 1 is circulus, and shape, the size of polylith wear-resistant block 2 are all identical; Polylith wear-resistant block 2 arranges the outside of internal layer 1, and form a circle, namely the inner surface of polylith wear-resistant block 2 contacts with the outer surface of internal layer 1, and the side of polylith wear-resistant block 2 is contacting one another, forms circulus; Every block wear-resistant block 2 is all fixedly connected with internal layer 1 by two fastening bolts 3, and fastening bolt 3 is connected with wear-resistant block 2 from the inner surface of internal layer 1 through internal layer 1.
If needs are changed or when keeping in repair a certain piece or a few pieces of wear-resistant blocks 2, only need corresponding fastening bolt 3 to pull down, and will not carry out changing, repairing by whole roller shell, so time saving and energy saving, change conveniently.And the requirement of internal layer 1 pair of material abrasion resistance is relatively low, and its material can be chosen as normal steel casting, save material cost.
Particularly, the quantity of polylith wear-resistant block 2 can set according to the size of roller shell in use procedure or actual needs, such as, can be set as 20 ~ 50 pieces, and such as, in actual use, the quantity of wear-resistant block 2 can be set to 24 pieces.
In addition, consider that ceramic-metallic abrasion resistance properties will be far superior to wear-resistant metal material, and cermet has unrepairable as main body, so, the wear-resistant block 2 arranged in wear-resisting split roller shell of the present utility model comprises wear-resisting main body 201 and wear resistant filler 202, wear-resisting main body 201 is metal wear resistant material material, and wear resistant filler 202 is cermet material.
Particularly, the outer surface of wear-resisting main body 201 is provided with n hole, wherein n be more than or equal to 1 positive integer, be all embedded with wear resistant filler 202 in n hole.Particularly, the distribution in n hole can set according to the actual needs in actual use procedure, and such as, when actual setting, n hole can be uniformly distributed, also can in the relative dense distribution in key wear position.
Above-described content can combine enforcement individually or in every way, and these variant are all within protection domain of the present utility model.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit.Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
