Abstract
The present invention relates to a kind of large-sized grinder gearwheel seal arrangement, the outside of the nearly gearwheel end of gear cover is fixed wtih fine wool felt seal layer and trim ring, fine wool felt seal layer is between trim ring and gear cover, the lower end of fine wool felt seal layer contacts with backing ring, the outer end band rib of backing ring, the inner is fixed on gearwheel.Along with the rotation of gearwheel, lubricant oil on gearwheel can splash the junction of backing ring and fine wool felt seal layer, the radial seal formed due to fine wool felt and backing ring effectively hinders fluid and oozes out, and with rib on backing ring, lubricant oil can come back to the profile of tooth engagement place of gearwheel.Due to the rubber asbestos sealing in the top insertion canine tooth of the angle steel on backing ring race, thus gearwheel is connected be an entirety with backing ring, and the more common end face seal of sealing effect is better.Thus reach and not easily make lubricant oil leak outside.Because trim ring is provided with lower stop edge, effectively prevent dust and enter gearwheel.
Description
Technical field
The present invention relates to a kind of large-sized grinder canine tooth seal arrangement, especially a kind of large-size ball mill gearwheel seal arrangement, belong to mechanical engineering field.
Background technique
At present, the sealing of pebble mill gearwheel is generally divided into radial seal and end face seal, and its end face seal can only play dustproof effect, and because felt is direct and gearwheel end face produces relative sliding, oil-leakage-prevention effect is bad, does not generally adopt; Its radial seal preventing dust leakage of oil effect is better, but gearwheel two ends must cast out convex edge and process circumferential surface except active flank, felt and canine tooth circumferencial direction just can be made to produce relative sliding, thus play the effect of radial seal, gearwheel weight so virtually can be made to increase, cost up, if and long-time running, oil easily oozes out from sealing, and the fluid oozed out takes care of the pence, outside final inflow gearwheel.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of large-sized grinder gearwheel seal arrangement is provided, sealing apparatus structure is simple, cost is low, can reduce gearwheel weight, reduces cost of production, can prevent again dust from entering gearwheel, and the oil leak on gear can be prevented, its practical Be very effective, be a kind of gearwheel seal arrangement with radial seal and end face seal dual functions.
For achieving the above object, the present invention adopts following technical proposals:
A kind of large-sized grinder gearwheel seal arrangement, the outside of the nearly gearwheel end of gear cover is fixed wtih fine wool felt seal layer and trim ring, and fine wool felt seal layer is between trim ring and gear cover, and the lower end of fine wool felt seal layer contacts with backing ring, the outer end band rib of backing ring, the inner is fixed on gearwheel.
Described gearwheel is provided with groove, is provided with rubber asbestos sealing layer in groove, the top and rubber asbestos sealing layer inserted in canine tooth race of end band angle steel in backing ring.
The lower bands bolt hole of described backing ring the inner is also fixed on gearwheel by bolt connection part.
Described trim ring with lower stop edge, preferred Z-shaped plate shape.
Described fine wool felt seal layer and trim ring are fixed on gear cover by bolt connection part.
Gearwheel is in rotation process, and gear cover and trim ring and fine wool felt seal layer geo-stationary, backing ring, rubber asbestos sealing layer rotate together with gearwheel, fine wool felt seal layer and backing ring relative sliding.Along with the rotation of gearwheel, lubricant oil on gearwheel can splash the junction of backing ring and fine wool felt seal layer, the radial seal formed due to fine wool felt and backing ring effectively hinders fluid and oozes out, and with rib on backing ring, lubricant oil can come back to the profile of tooth engagement place of gearwheel.Due to the rubber asbestos sealing in the top insertion canine tooth of the angle steel on backing ring race, thus gearwheel is connected be an entirety with backing ring, and the more common end face seal of sealing effect is better.Thus reach and not easily make lubricant oil leak outside.Because trim ring is provided with lower stop edge, effectively prevent dust and enter gearwheel.
The invention has the beneficial effects as follows, provide the double-sealing device of a kind of gearwheel radial seal and end face seal, and alleviate the weight of gearwheel, reduce cost, effectively ensure that gearwheel normally runs.

Fig. 2 is the partial enlarged drawing at I place on Fig. 1 of the present invention;
Fig. 3 is the structural representation of backing ring in the present invention;
Wherein: 1. gear cover, 2. fine wool felt seal layer, 3. bolt fastener a, 4. trim ring, 5. backing ring, 6. bolt fastener b, 7. rubber asbestos sealing layer, 8. gearwheel.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, 2, a kind of large-sized grinder gearwheel seal arrangement, the outside of the nearly gearwheel end of gear cover 1 is fixed wtih fine wool felt seal layer 2 and trim ring 4, fine wool felt seal layer 2 is between trim ring 4 and gear cover 1, the lower end of fine wool felt seal layer 2 contacts with backing ring 5, the outer end band rib of backing ring 5, the inner is fixed on gearwheel 8.
Described gearwheel 8 is provided with groove, is provided with rubber asbestos sealing layer 7 in groove, the top and rubber asbestos sealing layer 7 inserted in canine tooth race of end band angle steel in backing ring 5.
Trim ring 4 is connected with gear cover 1 by bolt connection part a3; The lower bands bolt hole of backing ring 5 the inner is also connected with gearwheel 8 by bolt connection part b6.Trim ring 4 is with lower stop edge.
Gearwheel 8 is in rotation process, and gear cover 1 and trim ring 4 and fine wool felt seal layer 7 geo-stationary, backing ring 5, rubber asbestos sealing layer 7 rotate together with gearwheel 8, fine wool felt seal layer 2 and backing ring 5 relative sliding.Along with the rotation of gearwheel, lubricant oil on gearwheel 8 can splash the junction that backing ring 5 seals with fine wool felt seal layer 2, the radial seal formed due to fine wool felt seal layer 2 and backing ring 5 effectively hinders fluid and oozes out, and with rib on backing ring 5, lubricant oil can come back to the profile of tooth engagement place of gearwheel 8.Due to the rubber asbestos sealing layer 7 in the top insertion gearwheel 8 of the angle steel on backing ring 5 groove, thus gearwheel 8 is connected be one overall with backing ring 5, and the more common end face seal of sealing effect is better.Thus reach and not easily make lubricant oil leak outside.Because trim ring 4 is provided with lower stop edge, effectively prevent dust and enter gearwheel.
