Description

A kind of wet method grinding machine seals structure with anti-slip
Technical field
The present invention relates to a kind of structure that seals, especially a kind of wet method grinding machine seals structure with anti-slip.
Background technology
At present, ball mill by wet process exposed drive gear wheel seals the knot mostly using oil scraper ring+sealing felt seal ash Structure, this to use at present injection lubrication gear prevent leakage of oil effectiveness comparison obvious, but for cylinder and The slip of end cap liner plate connecting hole etc. is revealed and entered inside gear house is that some effect does not all have.Therefore Usually have slip and enter gear house internal contamination lubricating oil, even have mineral grit to enter and be attached to the flank of tooth On, accelerate the abrasion of gear, thus reduce gear life.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, solve ball mill by wet process exposed drive gear wheel lubricating oil and let out Dew and cylinder, end cap etc. reveal slip enter gear house internal contamination lubricating oil, accelerate tooth surface abrasion, The problems such as gear life reduction.The present invention proposes a kind of new solution.
A kind of wet method grinding machine seals structure with anti-slip, and described sealing structure includes gear wheel (1), gear house (2), oil scraper ring one (3), oil scraper ring two (4) and sealing gasket (5), described gear wheel (1) is around it Axis rotates, and oil scraper ring one (3) is U shape, is arranged on gear wheel (1) opposite end Portion is with sealing gasket (5) fixing seal, and oil scraper ring two (4) is T-shape, is arranged on gear house (2) End, two side stretch into oil scraper ring one (3) with sealing gasket (5) fixing seal, the top of oil scraper ring two (4) Recess to stop wet method mill running time slip to enter gear house (2) internal.
Wherein, described oil scraper ring one (3), oil scraper ring two (4) are sectional making, carry out nothing at each segmentation Gap firm welding.
Wherein, sealing gasket (5) should compress and fit closely, bonding firmly with oil resistant bonding agent.
Accompanying drawing explanation
Fig. 1 is wet method grinding machine of the present invention anti-slip sealed structural representation and partial enlarged drawing.
Fig. 2 is that the anti-slip of wet method grinding machine of the present invention seals structure working principle figure.
Wherein, gear wheel (1), gear house (2), oil scraper ring one (3), oil scraper ring two, sealing gasket (5).
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is elaborated.
Such as Fig. 1, a kind of wet method grinding machine anti-slip sealing structure, described sealing structure include gear wheel (1), Gear house (2), oil scraper ring one (3), oil scraper ring two (4) and sealing gasket (5), described gear wheel (1) Rotating around its axis, oil scraper ring one (3) is U shape, is arranged on gear wheel (1) phase To both ends with sealing gasket (5) fixing seal, oil scraper ring two (4) is T-shape, is arranged on gear house (2) oil scraper ring is stretched into sealing gasket (5) fixing seal, the top of oil scraper ring two (4) in end, two side When the recess of (3) is to stop wet method mill running, slip enters gear house (2) inside.
Wherein, described oil scraper ring one (3), oil scraper ring two (4) are sectional making, carry out nothing at each segmentation Gap firm welding.
Wherein, sealing gasket (5) should compress and fit closely, bonding firmly with oil resistant bonding agent.
Its operation principle as in figure 2 it is shown, in Fig. 2 direction shown in arrow be slip leak point, in the operating of equipment During, gear wheel is as what cylinder rotated, and gear house is fixed.This structure is Oil scraper ring one is lengthened and improved structure, be allowed to, when there being slip to enter inside the web of gear, material to be stopped Slurry enters inside gear house.It is T-shaped, when having on cylinder that oil scraper ring two has that original L-type is modified to such as figure During slip drippage, can stop that slip enters inside gear house too.Oil scraper ring one, two is because of diameter relatively Greatly, it is sectional making when making, when therefore installing, after position adjustment puts in place, should be by each segmented seam Place's firm welding, it is impossible to have any gap.Meanwhile, sealing gasket also should compress and fit closely, when needing also Application oil resistant bonding agent is bonding firmly.
Invention increases anti-slip structure, can effectively prevent slip from entering inside gear house, prevent lubricating oil Pollution, stop the heel and toe wear of gear, increase the service life of gear.
The above is only the preferred embodiment for the present invention, it is noted that for the common skill of the art For art person, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and modification, These improve and modification also should be considered as protection scope of the present invention.
