Abstract
The invention relates to a seal device for a carrier roller. The seal device comprises an inner seal assembly and an outer seal assembly, wherein the outer seal assembly comprises a small cylinder body and an outer seal plate, the small cylinder body is provided with a cylindrical hole, the outer seal plate is arranged on the outer side of one end of the small cylinder body, the inner seal assembly comprises a large cylinder body and an inner seal plate, the inner seal plate is arranged on the inner wall of the large cylinder body and is matched with the outer circumference of the small cylinder body, and the outer side of the inner seal plate and the inner side of the outer seal plate are inserted to form a mortise and tenon structure. The seal device for the carrier roller, disclosed by the invention, has the advantages of reasonable design, simple structure and excellent seal performance, ensures that the interior of the carrier roller is not influenced by corrosive media, such as dust, air, liquid and the like, and prolongs the service life of the carrier roller.
Description
Technical field
The present invention relates to a kind of carrying roller on material conveyor, particularly relate to a kind of seal device for carrier roller.
Background technology
At present, in industries such as mining industry, chemical industry, coking, iron and steel, thermoelectricity, coal washing, grain processing, sugar industry, salt, cement, lime, sandstone, glass, metallurgy, chemical fertilizer conveying, coking coal supply, port and piers, the domestic carrying roller overwhelming majority still adopts iron and steel roller, heavy, energy consumption is high, staring torque greatly, not withstanding corrosion, in corrosion with under wearing and tearing synergy, service life is short.In addition the center shaft of carrying roller generally adopts steel antifriction-bearing box, needs intermittent oiling, and due to sealing effectiveness poor, be unsuitable for working in humidity, dust, corrosive environment, drastically influence normal operation and the transport efficiency of conveyer.
Summary of the invention
The present invention, in order to solve weak point of the prior art, provides a kind of light and handy, seal device for carrier roller that withstanding corrosion, long service life, sealing effectiveness are good.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of seal device for carrier roller, comprise inner seal liner and outside seal, outside seal comprises the little cylindrical shell with cylindrical hole and the outer gland sealing plate be located at outside little cylindrical shell one end, inner seal liner comprises large cylinder and inner sealing plate, inner sealing plate is located at large cylinder inwall and coordinates with little cylindrical shell excircle, and between inside the outside of inner sealing plate and outer gland sealing plate, grafting arranges formation tenon structure.
Described outer gland sealing plate excircle forms the groove of annular arrangement to the bending of large cylinder side, seals to contact to coordinate after large cylinder closes on the bending of groove one side end with groove inner wall.
Described tenon structure intersects from inside to outside and is provided with three groups.
Described little cylindrical shell and outer gland sealing plate adopt ABS resin integrated injection molding to form.
Described large cylinder and inner sealing plate adopt ABS resin integrated injection molding to form.
Adopt technique scheme, little cylindrical shell is arranged on the center shaft of carrying roller, and the inner of little cylindrical shell and the inner ring top force fit of bearing, force fit is pushed up in the inner of large cylinder and the outer ring of bearing, and center shaft is provided with the jump ring being positioned at little cylindrical shell outer end.Sealing property of the present invention is superior, labyrinth type (tenon structure and coordinating between groove with little cylindrical shell outer end) waterproof and dustproof sealing arrangement (outside seal and inner seal liner) is adopted to seal bearing, the outside jump ring that adopts is located, make sealing property reach best result of use, can effectively prevent the Korrosionsmediums such as dust, gas, liquid from entering carrying roller inside and damaging bearing.
The present invention adopts ABS resin injection molded, ABS resin is one of five large synthetic resin, its impact resistance, resistance to effect of heat, low temperature resistance, chemical proofing and excellent electrical properties, also there is the features such as easy processing, product size is stable, surface gloss property is good, easy application, painted, surface metallization, plating, welding, hot pressing and the secondary processing such as bonding can also be carried out, being widely used in the industrial circles such as machinery, automobile, electronic apparatus, instrument and meter, weaving and building, is the thermoplastic engineering plastic that a kind of purposes is extremely wide.
The present invention is reasonable in design, structure is simple, has good sealing property, guarantees that carrying roller is inner not by the impact of the Korrosionsmediums such as dust, gas, liquid, thus extends the service life of carrying roller.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of seal device for carrier roller of the present invention, comprise inner seal liner and outside seal, outside seal comprises the little cylindrical shell 11 with cylindrical hole 10 and the outer gland sealing plate 12 be located at outside little cylindrical shell 11 one end, inner seal liner comprises large cylinder 13 and inner sealing plate 14, inner sealing plate 14 is located at large cylinder 13 inwall and coordinates with little cylindrical shell 11 excircle, and between inside the outside of inner sealing plate 14 and outer gland sealing plate 12, grafting arranges and forms tenon structure 7.Tenon structure 7 is annular arrangement, and intersect from inside to outside and be provided with three groups, this fully can strengthen sealing property.Outer gland sealing plate 12 excircle forms the groove 15 of annular arrangement to the bending of large cylinder 13 side, contacts coordinate after large cylinder 13 closes on the bending of groove 15 1 side end with groove 15 inner wall sealing.Little cylindrical shell 11 and outer gland sealing plate 12 adopt ABS resin integrated injection molding to form.Large cylinder 13 and inner sealing plate 14 adopt ABS resin integrated injection molding to form.
Little cylindrical shell 11 is arranged on the center shaft of carrying roller, and the inner of little cylindrical shell 11 and the inner ring top force fit of bearing, force fit is pushed up in the inner of large cylinder 13 and the outer ring of bearing, and center shaft is provided with the jump ring being positioned at little cylindrical shell 11 outer end.Sealing property of the present invention is superior, labyrinth type (tenon structure 7 and coordinating between groove 15 with little cylindrical shell 11 outer end) waterproof and dustproof sealing arrangement (outside seal and inner seal liner) is adopted to seal bearing, the outside jump ring that adopts is located, make sealing property reach best result of use, can effectively prevent the Korrosionsmediums such as dust, gas, liquid from entering carrying roller inside and damaging bearing.
