Abstract
The utility model discloses a kind of single lip outside framework oil seal, including metallic framework and rubber seal ring, the metallic framework section is the distressed structure of L-type；The outer diameter of the rubber seal ring is static seal surface, and internal diameter is dynamic sealing surface, connects internal diameter and outer diameter is transition part, dynamic sealing surface sets sealing lip, and the sealing lip outer portion is equipped with spring；The axially extending side of metallic framework is concordant with static seal surface, and completely exposed；Metallic framework radially extends side across the transition part of rubber seal ring and is inserted into dynamic sealing surface.List lip outside framework oil seal provided by the utility model, outer diameter are that rubber partly wraps design, it is ensured that the leakproofness of outer diameter, while there is preferable stability and accurately equip characteristic, single lip setting is generally used in environment of the sealed pressure lower than 0.3bar.
Description
Technical field
The utility model relates to a kind of single lip outside framework oil seals, belong to seal fitting technical field.
Background technique
Oil sealing is a kind of sealing element for preventing lubricating oil with pressure from leaking out, and is widely used in household electrical appliances, automobile engine, rubs
In the product that motorcycle etc. needs oil, gas and water to seal.Oil-sealing arrangement is in addition to needing to have good sealing performance, it is also necessary to good
Assembly properties, be suitable for special working environment.
Utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of outside framework oil seal.
Technical solution: in order to solve the above technical problems, the technical solution adopted by the utility model is:
A kind of list lip outside framework oil seal, including metallic framework and rubber seal ring, the outer diameter of the rubber seal ring are static state
Sealing surface, internal diameter are dynamic sealing surface, connect internal diameter and outer diameter is transition part, dynamic sealing surface sets sealing lip, the sealing
Lip outer portion sets annular groove, is equipped with spring in annular groove；The metallic framework section is the distressed structure of L-type；Metal bone
The axially extending side of frame is concordant with static seal surface, and completely exposed；Metallic framework radially extends side across rubber seal ring
Transition part and be inserted into dynamic sealing surface.
Further, the axially extending side of the metallic framework and the junction for radially extending side are in S kinking structure, and S is curved
It is bonded with static seal surface inside.
Further, the outer ring end of the axially extending side of the metallic framework is equipped with chamfering.
Further, the spring side is equipped with spring protection lip.
Further, the metallic framework and spring are made of carbon steel material.
Further, the rubber seal ring is made of hydrogenated nitrile-butadiene rubber.
The utility model has the advantages that list lip outside framework oil seal provided by the utility model, metallic framework a part are coated by rubber seal ring,
A part of completely exposed, the rubber half of oil sealing outer diameter wraps design and ensures the leakproofness of outer diameter, while having preferable stability
And accurate assembly properties；Sealing lip outer portion sets spring, provides the certain binding force of oil sealing lip and extends the oil sealing service life, leads to
It is often used in environment of the sealed pressure less than 0.3bar.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of list lip outside framework oil seal, including metallic framework and rubber seal ring, the rubber seal ring
Outer diameter is static seal surface 1, and internal diameter is dynamic sealing surface 2, and connecting rubber sealing ring outer diameter and internal diameter are transition part 3；It is described
Dynamic sealing surface 2 sets sealing lip 20, and 20 outer portion of sealing lip sets annular groove, is equipped with spring 3,3 side of spring in annular groove
Equipped with spring protection lip 30.
The metallic framework section is the distressed structure of L-type, and the axially extending side 41 of metallic framework and static seal surface 1 are flat
Together, and completely exposed, metallic framework radially extends side 42 across the transition part 3 of rubber seal ring and is inserted into dynamic sealing surface 2.
The axially extending side of metallic framework 41 with radially extend the junction of side 42 in S kinking structure 3, S it is curved on the inside of static seal surface
Fitting, oil sealing outer diameter are in half packet form of rubber, it is ensured that the leakproofness of outer diameter.
The outer ring end of the axially extending side 41 of metallic framework is equipped with chamfering 44, it is ensured that accurate assembly properties.
The metallic framework and spring are made of carbon steel material, and metallic framework, which can increase rigidity, become oil sealing will not easily
Shape, spring then provide the certain binding force of oil sealing lip and extend the oil sealing service life.
The rubber seal ring is made of hydrogenated nitrile-butadiene rubber, and chemical property is stablized, and has elastic nature, sealing effect
It is good.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
