Abstract
The invention relates to a slurry-proof sealing structure for a wet process mill. The structure comprises a big gear wheel (1), a gear hood shell (2), first oil retaining rings (3), second oil retaining rings (4) and sealing pads (5). The big gear wheel (1) rotates around the mean axis of the big gear wheel. The first oil retaining rings (3) are shaped like the Chinese character 'ao' and arranged on the two opposite ends of the big gear wheel (1) and fixed and sealed with the corresponding sealing pads (5). The T-shaped second oil retaining rings (4) are arranged on two side wall ends of the gear hood shell (2) and fixed and sealed with the corresponding sealing pads (5). The upper portions of the second oil retaining rings (4) penetrate into the concave portions of the first oil retaining rings (3) to prevent slurry from entering into the gear hood shell (2) when the wet process mill operates. According to the slurry-proof sealing structure for the wet process mill, the problems that lubricant of an exposed drive big gear wheel of a wet process mill leaks, the slurry leaks at the places such as a cylinder body and an end cover and contaminates lubricant in a gear hood shell, gear face abrasion is accelerated and the service life of the big gear wheel is shortened are solved.
Description
Technical field
The present invention relates to a kind of sealing configuration, anti-slip sealing configuration for especially a kind of wet method grinding machine.
Background technique
At present, the sealing of ball mill by wet process open type transmission gearwheel adopts the structure of flinger ring+sealing felt seal ash mostly, this gear to current employing jet lubrication prevent that leakage of oil effect is obvious, but to reveal and enter gear house inside be that some effect does not all have for the slip located for cylindrical shell and end cap liner plate attachment hole etc.Therefore usually have slip and enter gear house internal contamination lubricant oil, even have mineral grit to enter and be attached on the flank of tooth, accelerated the wearing and tearing of gear, thereby reduce gear life.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, solution ball mill by wet process open type transmission gearwheel oil leakage and cylindrical shell, end cap etc. are located to reveal slip and are entered gear house internal contamination lubricant oil, accelerate the problems such as tooth surface abrasion, gear life reduction.The present invention proposes a kind of new solution.
A kind of wet method anti-slip sealing configuration for grinding machine, described sealing configuration comprises gearwheel (1), gear house (2), flinger ring one (3), flinger ring two (4) and sealing gasket (5), described gearwheel (1) rotates around its axis, flinger ring one (3) is " recessed " font, be arranged on gearwheel (1) opposite end portion with sealing gasket (5) fixing seal, flinger ring two (4) is T-shape, be arranged on the end, two side of gear house (2) with sealing gasket (5) fixing seal, the recess that flinger ring one (3) is stretched on the top of flinger ring two (4) slip when stopping wet method mill running enters gear house (2) inside.
Wherein, described flinger ring one (3), flinger ring two (4) are sectional making, and seamless firm welding is carried out in each segmentation place.
Wherein, sealing gasket (5) should compress and fit closely, bonding firmly with oil resistant binder.
Accompanying drawing explanation
Fig. 1 is anti-slip sealed structural representation and partial enlarged drawing for wet method grinding machine of the present invention.
Fig. 2 is anti-slip sealing configuration fundamental diagram for wet method grinding machine of the present invention.
Wherein, gearwheel (1), gear house (2), flinger ring one (3), flinger ring two, sealing gasket (5).
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As Fig. 1, a kind of wet method anti-slip sealing configuration for grinding machine, described sealing configuration comprises gearwheel (1), gear house (2), flinger ring one (3), flinger ring two (4) and sealing gasket (5), described gearwheel (1) rotates around its axis, flinger ring one (3) is " recessed " font, be arranged on gearwheel (1) opposite end portion with sealing gasket (5) fixing seal, flinger ring two (4) is T-shape, be arranged on the end, two side of gear house (2) with sealing gasket (5) fixing seal, the recess that flinger ring one (3) is stretched on the top of flinger ring two (4) slip when stopping wet method mill running enters gear house (2) inside.
Wherein, described flinger ring one (3), flinger ring two (4) are sectional making, and seamless firm welding is carried out in each segmentation place.
Wherein, sealing gasket (5) should compress and fit closely, bonding firmly with oil resistant binder.
As shown in Figure 2, in Fig. 2, direction shown in arrow is slip leak point to its working principle, and in the operation process of equipment, gearwheel is along with cylindrical shell rotates, and gear house is fixed.This structure is that flinger ring one is lengthened and improve structure, makes it, when having slip to enter inside the web of gear, can stop that slip enters gear house inside.Flinger ring two has original L-type to be modified to T-shaped as figure, when having slip drippage on cylindrical shell, can stop that too slip enters gear house inside.Flinger ring one, two, because diameter is larger, is sectional making when making, and while therefore installing, after adjusting to the right place in position, should, by each segmentation seam crossing firm welding, can not have any gap.Meanwhile, sealing gasket also should compress and fit closely, also applies oil resistant binder bonding firmly while needing.
The present invention has increased anti-slip structure, can effectively prevent that slip from entering gear house inside, prevents the pollution of lubricant oil, stops the heel and toe wear of gear, increases the working life of gear.
The above is only the preferred embodiment for the present invention; it should be pointed out that the member of ordinary skill for the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
Claims (3)
