Abstract
Disclosed is a wear-resisting crushing roller. The main body of the wear-resisting crushing roller is a rotating shaft mechanism, wherein a wear-resisting outer sleeve is sleeved on the rotating shaft mechanism and is fixed through a pressure ring and a hydraulic nut. The wear-resisting outer sleeve is made of hard wear-resisting metal material. A plurality of grooves which are distributed in annular mode are arranged in the wear-resisting outer sleeve, wherein a detachable wear-resisting ceramic piece is installed in each groove in inserted mode, the lower portion of each wear-resisting ceramic piece is a wedge cone structure, and the upper portion of each wear-resisting ceramic piece is a half ball structure. The wear-resisting crushing roller is convenient to machine, easy to assemble, high in crushing efficiency and long in service life.
Description
Technical field
The utility model belongs to the broken manufacture field of mineral, is specially the Novel hard alloy saw blade that a kind of circular saw machine that cuts high hard material is used.
Background technology
In general, high abrasion-resistant roller shaft is widely used in fields such as ore dressing, industry screenings, the high abrasion-resistant roller shaft that uses mainly is to adopt resin and diamond to make, wherein, resin material is not long service life, and diamond roller bearing one comes cost higher, and manufacturing procedure is also comparatively complicated in addition, and some metalliferous materials are had no idea.Thereby often to use the alloy roller bearing.
Common alloy roller bearing all is to be enclosed with wear-resistant material layer in the mandrel outside, because only a wherein very little part of roller bearing is fixed and accounted for to abration position when much mechanically using, when high abrasion-resistant roller shaft may wear to certain degree, whole high abrasion-resistant roller shaft 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.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of wear-resisting broken roller bearing, and this roller bearing carries out fragmentation to high hard material under the high speed rotary state, when guaranteeing crushing effect, can guarantee the service life of roller bearing itself.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of wear-resisting broken roller bearing, its main body is a turning cylinder mechanism, cover has a wear-resisting overcoat and carries out maintenance by a pressure rings and a hydraulic nut on it; Described wear-resisting overcoat is that the hard, wear-resistant metal material is made, and is provided with the groove that some ring-types are arranged on it, and is fitted with a removable wear-resistant ceramic spare in each groove.
In the utility model, described wear-resistant ceramic spare bottom is the wedge shape wimble structure, and top is a semiglobe.
In the utility model, during wear-resistant ceramic spare serious wear, can replace it, the wedge shape bottom of wear-resistant ceramic spare 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 pretightning force space is provided simultaneously.
Beneficial effect: the utility model technique is simple, and is easy to process, and assembling axially producing larger stress, is connected as a single entity the mandrel of roller bearing, wear-resisting overcoat, wear-resistant ceramic spare and hydraulic nut easily, and clamping force is very large, is difficult for loosening; When being used for the high hard material such as breaking ores, can utilize ceramic Tapered Column to cushion, working (machining) efficiency is high, long service life.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
The specific 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.
In the preferred embodiment referring to a kind of wear-resisting broken 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 carbide alloy, have 16 ring-type wedge-shaped impressions on it, the wear-resistant ceramic spare 3 that wear-resistant ceramic is made is installed on the annular recess, between the wedge-shaped impression on the lower end of wear-resistant ceramic spare 3 and the wear-resisting overcoat 2, leaves the high fit clearance of 3mm.
In addition, also be provided with pressure rings 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, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment 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.
Claims (2)
1. wear-resisting broken roller bearing, its main body is a turning cylinder mechanism, cover has a wear-resisting overcoat and carries out maintenance by a pressure rings and a hydraulic nut on it; Described wear-resisting overcoat is that the hard, wear-resistant metal material is made, be provided with the groove that some ring-types are arranged on it, and be fitted with a removable wear-resistant ceramic spare in each groove, the described wear-resistant ceramic spare bottom of stating is the wedge shape wimble structure, and top is a semiglobe.
2. a kind of wear-resisting broken roller bearing according to claim 1 is characterized in that, space for 3-5mm is left highly as the buffer area in the wedge shape bottom of described wear-resistant ceramic spare and the connection place of wear-resisting overcoat.
