Abstract
This utility model provides one to carry reeded low friction integral seal circle, including skeleton I, skeleton II and rubbery sealed body.Described skeleton I and skeleton II are L-type skeleton, they formation toroidal cavities positioned opposite.Described rubbery sealed body is positioned at toroidal cavity.The lower end of described rubbery sealed body is coated on the lower end of skeleton I.Described rubbery sealed body has three sealing lips, the respectively first lip, the second lip and the 3rd lip.These three sealing lip and skeleton the most mutually surround three annular seal spaces.Being provided with some grooves on described rubbery sealed body, these grooves connect with corresponding annular seal space.This utility model is additionally arranged groove so that the storge quality of annular seal space is more preferable, and service life is longer.
Description
Technical field
This utility model relates to technical field of sealing technology, is specifically related to that a kind of band is reeded low to rub
Wipe integral seal circle.
Background technology
Hub bearing is an important spare part of automobile, and its Main Function is load-bearing and is wheel
The transmission of hub provides and accurately guides.If the sealability of hub bearing is bad, can be caused it
The intrusion of the pollutant such as the leakage of internal lubrication fat and outside silt, steam, dust, not only
Affect the service life of bearing, the most also can cause serious vehicle accident.
In order to improve the sealability of hub bearing, existing current integrated sealing structure uses relatively
For extensively, generally three sealing lips and three annular seal spaces.But it is this easiest
Occur losing efficacy, cause degradation problem under greasy property afterwards, so how extend this low rub
The use time wiping integrated sealing structure has become the problem needing research.
Summary of the invention
The purpose of this utility model is to strengthen performance and the use of low friction integrated sealing structure
Life-span, it is provided that the reeded low friction integral seal circle of a kind of band.
Employed technical scheme comprise that such for realizing this utility model purpose, a kind of with
The low friction integral seal circle of groove, including skeleton I, skeleton II and rubbery sealed body.
Described skeleton I and skeleton II are L-type skeleton, they formation toroidal cavities positioned opposite.
Described rubbery sealed body is positioned at toroidal cavity.The lower end of described rubbery sealed body is coated on bone
The lower end of frame I.Described rubbery sealed body has three sealing lips, the respectively first lip,
Second lip and the 3rd lip.These three sealing lip and skeleton the most mutually surround three sealings
Chamber.Some grooves, these grooves and corresponding annular seal space it is provided with on described rubbery sealed body
Connection.
Further, described groove is rectangular channel, arcuate groove or dovetail groove.
Further, described groove is arranged on rubbery sealed body main part and/or sealing lip.
Of the present utility model have the technical effect that mathematical.Close in existing low friction monoblock type
In the contact of seal structure, it is provided with some grooves so that the capacity of annular seal space becomes big, simultaneously
Groove can adhere to lubricating oil, it is possible to absorption more to external substance, to increase this sealing structure
Performance and used life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: skeleton I 1, skeleton II 2, rubbery sealed body the 3, first lip 301, second
Lip the 302, the 3rd lip 303, groove 304.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not
It is construed as the above-mentioned subject area of this utility model and is only limitted to following embodiment.Without departing from
In the case of the above-mentioned technological thought of this utility model, according to ordinary skill knowledge with used
By means, make various replacement and change, protection domain of the present utility model all should be included in
In.
Seeing Fig. 1, the present embodiment provides one to carry reeded low friction integral seal circle,
Including skeleton I 1, skeleton II 2 and rubbery sealed body 3.Described skeleton I 1 and skeleton II 2 are equal
For L-type skeleton, they formation toroidal cavities positioned opposite.Described rubbery sealed body 3 is positioned at
In toroidal cavity.The lower end of described rubbery sealed body 3 is coated on the lower end of skeleton I 1.Described
Rubbery sealed body 3 has three sealing lips, respectively first lip the 301, second lip 302
With the 3rd lip 303.These three sealing lip and skeleton the most mutually surround three annular seal spaces.Institute
State and on rubbery sealed body 3, be provided with some grooves 304, these grooves 304 and corresponding sealing
Chamber connects.
In the present embodiment, described groove 304 is rectangular channel.Described groove 304 is arranged on rubber
In glue seal 3 main part and three sealing lips.So make the volume of three annular seal spaces
Increasing, groove 304 is attached with lubricating oil, active adsorption external substance simultaneously, strengthens and seals
The storage capacity in chamber, to extend the service life of this sealing structure.
