Abstract
The utility model discloses a rotary oil seal. The rotary oil seal comprises a ring-type main body, a metal framework and a spring, wherein the ring-type main body is made of rubber material. The ring-type main body comprises an inner ring, an outer ring and a transitional section connecting the inner ring and the outer ring. The inner ring is provided with a dustproof section and a sealing section. The spring and the sealing section are arranged to be adjacent. The metal framework is L-shaped and is embedded inside the transitional section and the outer ring. The two sides of the transitional section are provided with a plurality of face part carving teeth and inner part carving teeth used for positioning. The inner part carving teeth enables parts of the metal framework to expose in the air. Inserting strips made of rubber materials and covering the metal framework are formed at the inner part carving teeth, and an inserting slot for exposing the metal framework is formed between the inserting strips. The rotary oil seal has the advantages that a sealing effect of the rotary shaft seal is good, the area of the metal framework exposed in air is reduced greatly, the corrosion and rust of the metal framework are avoided as far as possible, the appearance is kept attractive, the service life is prolonged, and the sealing effect is kept.
Description
Technical field
The utility model relates to a kind of rubber seal, is specifically related to a kind of rotary oil seal.
Background technique
Rotary oil seal is to prevent lubricant oil with pressure to a class Sealing of outward leakage, and being widely used in household electrical appliances, motor car engine, motorcycle etc. needs in the product of oil, gas, water-stop.In order to increase the intensity of rotary oil seal, section all is embedded with metal frame within it, has the part metals skeleton to be exposed in the air in the existing oil sealing, time one is long, metal frame can be corroded gradually in the process of ingress of air and get rusty, and not only affects attractive in appearancely, and affects sealing effect.
Summary of the invention
Be to solve the deficiencies in the prior art, the purpose of this utility model is to overcome the defective of prior art, a kind of good sealing effect is provided, avoids the rotary oil seal of metal frame rust corrosion, long service life as far as possible.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
Rotary oil seal, it is characterized in that, comprise circumferential body, metal frame and the spring made by rubber material, above-mentioned circumferential body comprises interior ring, outer shroud and the transition part that connects interior ring and outer shroud, above-mentioned interior ring is formed with dustproof section and sealed department, the adjacent setting of above-mentioned spring and sealed department, above-mentioned metal frame are L shaped, are embedded in the inside of transition part and outer shroud; The two sides of above-mentioned transition part is formed with respectively several faces that are used for the location and carves tooth and the inner tooth of carving, the above-mentioned inner tooth of carving is exposed in the air part metals skeleton, above-mentioned inner the quarter on the tooth also is formed with a plurality of cutting of being made by rubber material that are covered on the metal frame, forms the slot of bare metal skeleton between the above-mentioned cutting.
Aforesaid rotary oil seal is characterized in that, the used metallic material of above-mentioned metal frame is iron.
Aforesaid rotary oil seal is characterized in that, the length direction of above-mentioned cutting is perpendicular to the above-mentioned inner length direction of carving tooth.
Aforesaid rotary oil seal is characterized in that, it is integrated that above-mentioned cutting is carved tooth with inside.
Aforesaid rotary oil seal is characterized in that, above-mentioned outer shroud and an above-mentioned facial end of carving the tooth homonymy are formed with rear chamfering.
Aforesaid rotary oil seal is characterized in that, above-mentioned outer shroud and an above-mentioned inner end of carving the tooth homonymy are formed with front chamfering.
Usefulness of the present utility model is: rotary oil seal good sealing effect of the present utility model, metal frame is exposed to airborne area and greatly reduces, avoided as much as possible the rust corrosion of metal frame, not only made its maintenance attractive in appearance, can also increase the service life and keep sealing effect.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of rotary oil seal of the present utility model;
Fig. 2 is cross-sectional view embodiment illustrated in fig. 1.
The implication of reference character among the figure: 1, metal frame, 2, spring, 3, interior ring, 4, outer shroud, 5, transition part, 6, dustproof section, 7, sealed department, 8, the facial tooth of carving, 9, the inner tooth of carving, 10, transplant a cutting, 11, rear chamfering, 12, front chamfering.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Referring to Fig. 1 and Fig. 2, rotary oil seal of the present utility model comprises circumferential body, metal frame 1 and the spring 2 of being made by rubber material.
Wherein, circumferential body comprises interior ring 3, outer shroud 4 and the transition part 5 that connects interior ring 3 and outer shroud 4, and interior ring 3 is formed with dustproof section 6 and sealed department 7.The effect of spring 2 is to make to form between sealed department 7 and the running shaft and cooperates closely, thus spring 2 and sealed department 7 adjacent settings, as shown in Figure 1.
Referring to Fig. 2, in order to increase the mechanical strength of rotary oil seal, embed L shaped metal frame 1 in the inside of transition part 5 and outer shroud 4, as a kind of preferred, metal frame 1 is made by iron material.Simultaneously, for the ease of in the production process rotary oil seal being positioned, the two sides of transition part 5 is formed with respectively several faces that are used for the location and carves tooth 8 and the inner tooth 9 of carving.As a kind of preferred, it all is spaced set each other that tooth 9 is carved in face tooth at quarter 8 and inside.
So, the inner tooth 9 of carving is exposed in the air part metals skeleton 1, and for effective bare area that reduces does not affect again the location simultaneously, the inner quarter on the tooth 9 also is formed with a plurality of cutting 10, forms the slot of bare metal skeleton 1 between the cutting 10.
As a kind of concrete structure, the length direction of cutting 10 is carved the length direction of tooth 9 perpendicular to inside.
Need to prove that for the ease of processing, cutting 10 is actually integrated with the inner tooth 9 of carving, and can adopt impact briquetting in actual the processing.
Further, chamfering 11 after outer shroud 4 and a facial end of carving tooth 8 homonymies are formed with, chamfering 12 before outer shroud 4 and an inner end of carving tooth 9 homonymies are formed with.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
