Abstract
The utility model relates to a hard alloy rolling shaft, disclosing a durable rolling shaft formed via combination of hard durable alloy and hard durable ceramic, wherein the hard alloy rolling shaft comprises a core shaft and a durable jacket which is integrally connected with the core shaft; the durable jacket is made of hard durable alloy; the durable jacket is provided with a plurality of annular grooves and equipped with a dismountable durable ring made of ceramic, and the durable ring can be replaced by a new durable ring when being wasted. The hard alloy rolling shaft is firm and durable, has long service life and is convenient to mount and dismount.
Description
Technical field
The utility model relates to the roller bearing technical field, is specially a kind of cemented carbide roller bearing of high abrasion.
Background technique
The high abrasion roller bearing is widely used in fields such as ore dressing, industry screenings, the high abrasion roller bearing that uses adopts in the mandrel outside and is enclosed with wear-resistant material layer at present, because only the wherein very little part of roller bearing is fixed and accounted for to abration position when much mechanically using, when the high abrasion roller bearing may wear to certain degree, whole high abrasion roller bearing scrapped, like this, not only strengthen the cost that ore dressing, industry are screened, but also caused the huge waste of roller bearing.Simultaneously, the roller bearing after scrapping also impacts environment easily.
The model utility content
The technical problem that the utility model solved is to provide a kind of cemented carbide roller bearing, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
The cemented carbide roller bearing, comprise mandrel and the wear-resisting overcoat that is connected as a single entity with described mandrel, wherein, wear-resisting overcoat is made for the hard, wear-resistant alloy, and wear-resisting overcoat is provided with some annular recess, and annular recess is even layout whole putting outside wear-resisting, dismantled and assembled wear ring is installed in described annular recess, these dismantled and assembled wear rings are that wear-resistant ceramic is made, and simultaneously, a pressure ring should be set also and a hydraulic nut carries out maintenance at the end of roller bearing.
In the utility model, dismantled and assembled wear ring is a cambridge ring, during serious wear, can replace it, the wedge shape bottom of dismantled and assembled wear ring and the connection place of wear-resisting overcoat are left and highly are to be used as the pressure buffer zone in the space of 3-5mm, and the pretightening force space is provided simultaneously.
Beneficial effect: the utility model is owing to by wear-resistant ceramic and wearable hard alloy combinations of pairs, axially producing big stress, be connected as a single entity the mandrel of roller bearing, wear-resisting overcoat, pressure ring and hydraulic nut, and clamping force is very big, is difficult for loosening; Compound roller bearing has very high rigidity, long service life when obtaining the prestressing force protection; And wear ring is replaceable structure, can be fast, install easily, dismantle, and compact structure is reasonable, and can effectively increase working life.
Description of drawings
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to the cemented carbide roller bearing of Fig. 1, mandrel 1 is connected as a single entity with wear-resisting overcoat 2, in the present embodiment, wear-resisting overcoat 2 is made for cemented carbide, have four ring-type wedge-shaped impressions on it, the dismantled and assembled wear ring 3 that wear-resistant ceramic is made is installed on the annular recess, between the wedge-shaped impression on the lower end of dismantled and assembled wear ring 3 and the wear-resisting overcoat 2, leaves the high matching gap of 3mm.
In addition, also be provided with pressure ring 4 and hydraulic nut 5 comes wear-resisting overcoat 2 is carried out the maintenance protection at the end of mandrel 1.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
