Abstract
The utility model discloses a gear lubricating and sealing device of a tube mill and belongs to the technical field of sealing devices. The gear lubricating and sealing device of the tube mill comprises a gear cover, a gearwheel, a felt, a pressing plate, a rubber sealing ring, and an oil guiding slot which is formed on the side surface of the gearwheel, wherein the gear cover is arranged outside the gearwheel; the felt is arranged on the outer side of the rubber sealing ring; the rubber sealing ring and the felt are tightly pressed by the pressing plate and connected to the gear cover; and the rubber sealing ring is contacted with the gearwheel. The gear lubricating and sealing device of the tube mill has the advantages that: the possibility of the direct contact between the gear oil and the gear cover is reduced; the oil leakage rate is reduced; dust is prevented from entering the gear cover; the problem that pollution is caused to lubricating oil due to abrasion of the felt is solved; and the gear lubricating and sealing device of the tube mill is simple in structure and convenient to install and detach.
Description
Technical field
The utility model discloses a kind of tuber grinder gear lubricating and sealing arrangement, belong to the seal arrangement technical field.
Background technique
On the edge of in the tuber grinder of transmission; Gearwheel is very crucial part; Gearwheel is connected on the cylindrical shell of tuber grinder through flange; The rotation of whole tuber grinder is exactly to drive the gearwheel rotation by small gear, thereby drives the rotation of mill body, and the lubrication effect of gearwheel directly affects the working life of gear.Gearwheel is wrapped in by gear cover, avoids greasy dirt to leak outside and causes waste, befouling environment; Blocks dust gets into, and prolongs the working life of gearwheel.In the existing technology, seal form hairiness felt seal, axial seal or the radial seal etc. of gear cover, but all fail to solve preferably gear cover leakage of oil problem.
Summary of the invention
To the problem that above-mentioned existing technology exists, the utility model provides a kind of tuber grinder gear lubricating and sealing arrangement, solves gear cover leakage of oil and dust effectively and gets into the inner problem of gear cover easily.
To achieve these goals; The technological scheme that the utility model adopts is: a kind of tuber grinder gear lubricating and sealing arrangement, comprise gear cover, gearwheel, felt and pressing plate, and gear cover is installed in the gearwheel outside; Also comprise rubber seal and the oil guide slot that is opened in the gearwheel side; Felt is installed in the rubber seal outside, and rubber seal and felt are connected in gear cover after being compressed by pressing plate, and rubber seal contacts with gearwheel.
Preferably, described rubber seal adopts double-lip sealing ring.
The beneficial effect of the utility model is: that has reduced that gear oil and gear cover directly contact maybe; Reduce the probability of leakage of oil greatly, avoid dust to get in the gear cover, also solved the problem that the felt wearing and tearing cause lubricant pollution simultaneously; And simple in structure, installation, convenient disassembly.
Description of drawings
Fig. 1 is the sectional view of the utility model;
Fig. 2 is the local enlarged diagram of Fig. 1.
Among the figure: 1, gear cover, 2, gearwheel, 3, rubber seal, 4, felt, 5, pressing plate, 6, oil guide slot.
Embodiment
To combine accompanying drawing that the utility model is described further below.
As depicted in figs. 1 and 2: the utility model comprises gear cover 1, gearwheel 2, felt 4 and pressing plate 5; Gear cover 1 is installed in gearwheel 2 outsides; The oil guide slot 6 that also comprises rubber seal 3 and be opened in gearwheel 2 sides; Felt 4 is installed in rubber seal 3 outsides, and rubber seal 3 is connected in gear cover 1 after being compressed by pressing plate 5 with felt 4, and rubber seal 3 contacts with gearwheel 2.
Preferably, described rubber seal 3 adopts double-lip sealing ring.
Offer oil guide slot 6 in the side of gearwheel 2, the oil on the gearwheel 2 flows into oil guide slot 6 from flank, flows into the oil sump of gear cover 1 bottom along oil guide slot 6; The sealing of employing double-lip sealing ring has avoided dust to get into gear cover 1, has also reduced the probability of leakage of oil simultaneously.
