Abstract
The invention discloses a rotary oil seal comprising an annular main body made of rubber materials, a metal framework and a spring. The annular main body comprises an inner ring, an outer ring and a transitional part for connecting the inner ring with the outer ring, a dustproof part and a sealing part are formed in the inner ring, the spring and the sealing part are arranged adjacently, and the metal framework is L-shaped, and is embedded in the transitional part and the outer ring; a plurality of face part carving teeth and inner part carving teeth used for positioning are formed on the two surfaces of the transitional part respectively, the metal framework is partially exposed in air due to the inner part carving teeth, inserting strips which are made of rubber materials and covers 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 beneficial effects 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 present invention relates to a kind of rubber seal, be specifically related to a kind of rotary oil seal.
Background technique
Rotary oil seal is the one type of Sealing that prevents that lubricant oil with pressure from outwards revealing, 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, portion 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 influences attractive in appearancely, and influences sealing effect.
Summary of the invention
Be to solve the deficiency of existing technology, the objective of the invention is to overcome the defective of existing technology, 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 present invention adopts following technological scheme:
Rotary oil seal; It is characterized in that, comprise circumferential body, metal frame and the spring processed by rubber material, above-mentioned circumferential body comprises interior ring, outer shroud and the transition part that connects interior ring and outer shroud; Ring is formed with dustproof portion and sealed department in above-mentioned; 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 several faces that are used to locate respectively 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 processed 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 an 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, an above-mentioned outer shroud and an above-mentioned facial end of carving the tooth homonymy are formed with the back chamfering.
Aforesaid rotary oil seal is characterized in that, an above-mentioned outer shroud and an above-mentioned inner end of carving the tooth homonymy are formed with preceding chamfering.
Usefulness of the present invention is: rotary shaft sealing good sealing effect of the present invention; Metal frame is exposed to airborne area and significantly reduces; Avoided the rust corrosion of metal frame as much as possible, 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 shaft sealing of the present invention;
Fig. 2 is a 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 portion, 7, sealed department, 8, the facial tooth of carving, 9, the inner tooth of carving, 10, transplant a cutting, 11, the back chamfering, 12, preceding chamfering.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to Fig. 1 and Fig. 2, rotary oil seal of the present invention comprises circumferential body, metal frame 1 and the spring of being processed by rubber material 2.
Wherein, the transition part 5 of interior ring 3 of ring 3, outer shroud 4 and connection and outer shroud 4 in circumferential body comprises, interior ring 3 is formed with dustproof portion 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, so spring 2 and sealed department 7 adjacent settings are 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 processed 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 several faces that are used to locate respectively and carves tooth 8 and the inner tooth 9 of carving.As a kind of preferred, it all is spaced set each other that face tooth at quarter 8 is carved tooth 9 with 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 influence the location simultaneously again, 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, be formed with back chamfering 11, chamfering 12 before an outer shroud 4 and an inner end of carving tooth 9 homonymies are formed with at an outer shroud 4 and a facial end of carving tooth 8 homonymies.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and embodiment does not limit the present invention in any form, and all employings are equal to the technological scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
