Abstract
A sealing device for a carrier roller comprises an inner sealing piece and an outer sealing piece. The outer sealing piece comprises a small barrel body provided with a cylindrical hole and an outer sealing plate arranged on the outer side of one end of the small barrel body. The inner sealing piece comprises a big barrel body and an inner sealing plate. The inner sealing plate is arranged on the inner wall of the big barrel body and is matched with the outer circumference of the small barrel body. A mortise and tenon structure is formed between the outer side of the inner sealing plate and the inner side of the outer sealing plate in an inserting mode. The sealing device for the carrier roller has the advantages of being reasonable in design, simple in structure and good in sealing performance so that avoidance of influence of corrosive medium of dust, gas, liquid and the like inside the carrier roller is guaranteed, and therefore service life of the carrier roller is prolonged.
Description
Technical field
The utility model relates to a kind of for the carrying roller on the material conveyor, relates in particular to a kind of carrying roller sealing arrangement.
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 the iron and steel roller, heavy, energy consumption is high, staring torque greatly, withstanding corrosion not, under corrosion and wearing and tearing synergy, service life is short.The center shaft of carrying roller generally adopts the steel antifriction-bearing box in addition, needs intermittent oiling, and because sealing effectiveness is poor, is unsuitable for working in humidity, dust, corrosive environment, is having a strong impact on normal operation and the transport efficiency of conveyer.
The utility model content
The utility model is in order to solve weak point of the prior art, and a kind of light and handy, withstanding corrosion, long service life, the good carrying roller sealing arrangement of sealing effectiveness are provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of carrying roller sealing arrangement, comprise inner seal liner and outside seal may, outside seal may comprises the little cylindrical shell with cylindrical hole and is located at the outer gland sealing plate in the little cylindrical shell one end outside, inner seal liner comprises large cylinder and inner sealing plate, inner sealing plate is located at the large cylinder inwall and cooperates with little cylindrical shell excircle, and pegging graft between the outside of inner sealing plate and the outer gland sealing plate inboard arranges the formation tenon structure.
Described outer gland sealing plate excircle is to the groove of large cylinder one side bending formation annular arrangement, and large cylinder contacts cooperation with the groove inner wall sealing after closing on groove one side end bending.
Described tenon structure intersects from inside to outside and is provided with three groups.
Described little cylindrical shell and outer gland sealing plate adopt the ABS resin integrated injection molding to form.
Described large cylinder and inner sealing plate adopt the ABS resin integrated injection molding to form.
Adopt technique scheme, little cylindrical shell is installed on the center shaft of carrying roller, the inner ring top force fit of the inner of little cylindrical shell and bearing, and top, the outer ring force fit of the inner of large cylinder and bearing, center shaft is provided with the jump ring that is positioned at little cylindrical shell outer end.The utility model sealing property is superior, adopt labyrinth type (cooperating between tenon structure and groove and the little cylindrical shell outer end) waterproof and dustproof sealing arrangement (outside seal may and inner seal liner) that bearing is sealed, the outside jump ring location of adopting, make sealing property reach best result of use, can prevent effectively that the Korrosionsmediums such as dust, gas, liquid from entering carrying roller inside and damaging bearing.
The utility model 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 have the characteristics such as easy processing, product size is stable, surface gloss property is good, easily application, painted, can also carry out surperficial spraymetal, plating, welding, hot pressing and the secondary processing such as bonding, being widely used in the industrial circles such as machinery, automobile, electronic apparatus, instrument and meter, weaving and building, is the extremely wide thermoplastic engineering plastic of a kind of purposes.
The utility model is reasonable in design, simple in structure, has good sealing property, guarantees that carrying roller inside is not subjected to the impact of the Korrosionsmediums such as dust, gas, liquid, thereby prolongs the service life of carrying roller.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of carrying roller sealing arrangement of the present utility model, comprise inner seal liner and outside seal may, outside seal may comprises the little cylindrical shell 11 with cylindrical hole 10 and is located at the outer gland sealing plate 12 in the little cylindrical shell 11 1 ends outside, inner seal liner comprises large cylinder 13 and inner sealing plate 14, inner sealing plate 14 is located at large cylinder 13 inwalls and cooperates with little cylindrical shell 11 excircles, pegs graft between the outside of inner sealing plate 14 and outer gland sealing plate 12 inboards to arrange to form tenon structure 7.Tenon structure 7 is annular arrangement, intersects from inside to outside to be provided with three groups, and this can fully strengthen sealing property.Outer gland sealing plate 12 excircles are to the groove 15 of large cylinder 13 1 side bendings formation annular arrangement, and large cylinder 13 contacts cooperation with groove 15 inner wall sealings after closing on groove 15 1 side end bendings.Little cylindrical shell 11 and outer gland sealing plate 12 adopt the ABS resin integrated injection molding to form.Large cylinder 13 and inner sealing plate 14 adopt the ABS resin integrated injection molding to form.
Little cylindrical shell 11 is installed on the center shaft of carrying roller, the inner ring top force fit of the inner of little cylindrical shell 11 and bearing, and top, the outer ring force fit of the inner of large cylinder 13 and bearing, center shaft is provided with the jump ring that is positioned at little cylindrical shell 11 outer ends.The utility model sealing property is superior, adopt labyrinth type (cooperating between tenon structure 7 and groove 15 and little cylindrical shell 11 outer ends) waterproof and dustproof sealing arrangement (outside seal may and inner seal liner) that bearing is sealed, the outside jump ring location of adopting, make sealing property reach best result of use, can prevent effectively that the Korrosionsmediums such as dust, gas, liquid from entering carrying roller inside and damaging bearing.
