Abstract
The utility model provides a rubbing crusher main shaft mechanism, include be close to the main shaft wherein one end the belt pulley installation department, be close to the blade disc installation department of the main shaft other end and lie in the belt pulley installation department and the blade disc installation department between the bearing installation department, the bearing installation department includes location portion and is located the installation department at location portion both ends, all be equipped with the end cover on the installation department, all install the several bearing between end cover and the location portion. The utility model discloses the increase of bearing has reduced the radial load of the crushing blade disc of front -end of spindle, has reduced equipment trouble and has rateed, and extension equipment life has effectively protected production normal operating.
Description
Technical field
The utility model relates to a kind of pulverizer main shaft mechanism.
Background technology
Pulverizer is as material-pulverizing device conventional at present, and main shaft bearing is generally less than two, because when pulverizer works, cutterhead self is heavier, more than High Rotation Speed centrifugal force can reach tonne, cause main shaft bearing not long for service life, increase checking maintenance cost, impact is produced and is normally carried out.
Utility model content
The utility model proposes a kind of pulverizer main shaft mechanism, solve the technical problem that bearing service life is short, checking maintenance cost is high.
The technical solution of the utility model is achieved in that a kind of pulverizer main shaft mechanism, comprise near main shaft wherein one end belt pulley installation portion, near the cutterhead installation portion of the main shaft other end and the axle bearing mount portion between belt pulley installation portion and cutterhead installation portion, described axle bearing mount portion comprises location division and is positioned at the installation portion at two ends, location division, described installation portion is equipped with end cap, between described end cap and location division, several bearing is all installed.
Wherein, described axle bearing mount portion is stepped, and wherein the diameter of location division is greater than the diameter of installation portion, the equal diameters of two ends, described location division installation portion.
Particularly, described bearing is four, and every two is one group, and each installation portion is provided with one group.
Further, described main shaft is fixed by locking nut near one end of cutterhead installation portion.
Further, be provided with packing ring between described locking nut and cutterhead installation portion and only enclose.
Further, described main shaft upper belt pulley installation portion, cutterhead installation portion all have keyway.
Further, wherein labyrinth seal is passed through near the end cap of cutterhead.
Compared with prior art, the beneficial effects of the utility model are: the increase of bearing reduces the radial load that front-end of spindle pulverizes cutterhead, reduces equipment failure rate, the extension device life-span, and available protecting produces normal operation.Meanwhile, bearing just can shut down repair and maintenance by continuous high speed running more than 15h, and available protecting produces normal operation, adds production capacity, has ensured selling time and income.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only 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.
See Fig. 1, a kind of pulverizer main shaft mechanism, comprise near main shaft wherein one end belt pulley installation portion 1, near the cutterhead installation portion 7 of the main shaft other end and the axle bearing mount portion between belt pulley installation portion 1 and cutterhead installation portion 7, described axle bearing mount portion comprises location division 2 and is positioned at the installation portion at two ends, location division 2, described installation portion is equipped with end cap 3, between described end cap 3 and location division 2, several bearing 4 is all installed.The increase of the utility model bearing 4 reduces the radial load that front-end of spindle pulverizes cutterhead, reduces equipment failure rate, the extension device life-span, and available protecting produces normal operation.
Described axle bearing mount portion is stepped, and wherein the diameter of location division 2 is greater than the diameter of installation portion, the equal diameters of two ends, described location division 2 installation portion.When installing bearing 4,2 pairs, location division bearing 4 plays fixing effect, and its middle (center) bearing 4 is closely arranged successively against location division 2, bearing 4 is located by end cap 3 away from the end of location division 2, be convenient to install, locate, without the need to adopting other positioning parts, save operation, reducing costs.
Described bearing 4 is four, and every two is one group, and each installation portion all installs one group.During work, bearing 4 just can shut down repair and maintenance by continuous high speed running more than 15h, and available protecting produces normal operation, adds production capacity, has ensured selling time and income.
Described main shaft is fixed by locking nut 8 near one end of cutterhead installation portion 7.During assembling, locked by each parts assembled by locking nut 8, prevent each component axial play, main shaft connects more firm between each parts when work.
Be provided with packing ring 6 between described locking nut 8 and cutterhead installation portion 7 and only enclose, in order to increase the reliability of locking nut 8 self-locking, when mounted, packing ring 6 being set between locking nut 8 and cutterhead and only enclosing.
Described main shaft upper belt pulley installation portion 1, cutterhead installation portion 7 all have keyway.When assembling, belt pulley, to be connected by key between cutterhead with main shaft, belt pulley, cutterhead are played to axial restraint and transmit the effect of axial force.
End cap 3 wherein near cutterhead is sealed by labyrinth 5.Dust effectively can be stoped to enter bearing 4 chamber, thus extend the service life of bearing 4.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
