All there was only radial direction static seal, sealing effectiveness is bad, for this phenomenon, it is necessary to which it is further improved.
The content of the invention
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of more lip mouth oil seals,
It reduces the generation of its leakage phenomenon, extends its service life, reduces manufacturing cost and use cost.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of more lip mouth oil seals, it includes：
Oil sealing main body, the oil sealing main body has at least two lips, and axial direction of the lip along oil sealing main body is side by side
It is arranged on the inner ring wall of oil sealing main body, the lip is used to be interference fitted so as to realize to axle dynamic sealing with axle；
Seal is held, the end seal is arranged on the side end face of oil sealing main body, so that the end seal is oil sealing
Main body provides axial static seal；
Outer ring seal, the outer ring seal are arranged in the collar wall of oil sealing main body, so as to the outer ring seal
Radial direction static seal is provided for oil sealing main body.
It is described so as to be sealed well to the axial direction of oil sealing main body further for enabling end seal effectively to extrude
The downside of end seal is connected with the side end face of oil sealing main body, is provided with 1 points on the upper side of the end seal
Shape contact site.
Further, set fluted in the collar wall of the oil sealing main body, the outer ring seal is inlaid in groove.
Further, the oil sealing main body is made up of polytetrafluoroethylmaterial material.
Further, the end seal is made up of elastomeric material.
Further, the outer ring seal is O-ring seal.
Further, the lip is provided with two or three or four.
After employing above-mentioned technical proposal, more lip mouth oil seals of the present utility model are provided with multiple lips, and lip leads to
Being interference fitted to play the effect of sealing between axle is crossed, with the increase of product height, lip increases, and sealing effectiveness is better；
End face seal body when oil sealing is installed can by 13% or so compression ratio, so as to for oil sealing provide well axial static seal；Outer ring
Seal, which is squeezed, provides its radial direction static seal, is easy to oil sealing to install, reduces the processing request to installing cavity.Arranged more than
Apply, so as to reduce the generation of its leakage phenomenon, extend its service life, reduce manufacturing cost and use cost.
Brief description of the drawings
Fig. 1 is the structural representation of the first structure of more lip mouth oil seals of the present utility model；
Fig. 2 is the structural representation of second of structure of more lip mouth oil seals of the present utility model；
Fig. 3 is the structural representation of the third structure of more lip mouth oil seals of the present utility model.
Embodiment
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model.
As shown in Fig. 1 ~ 3, a kind of more lip mouth oil seals, it includes：
Oil sealing main body 1, the oil sealing main body 1 have at least two lips 11, and axle of the lip 11 along oil sealing main body 1
To being disposed in parallel on the inner ring wall of oil sealing main body 1, the lip 11 is used to be interference fitted so as to realize to axle dynamic sealing with axle；
Seal 2 is held, the end seal 2 is arranged on the side end face of oil sealing main body 1, so that the end seal 2 is
Oil sealing main body 1 provides axial static seal；
Outer ring seal 3, the outer ring seal 3 are arranged in the collar wall of oil sealing main body 1, so that the outer ring seals
Body 3 is that oil sealing main body 1 provides radial direction static seal.
Specifically, as shown in Fig. 1 ~ 3, the lip 11 has axially contact portion 111 and in being bent up curved convergence part
112, axially contact portion 111 matches with the cylindrical contact of axle.Between having between adjacent lip 11 in the axial direction of oil sealing main body 1
Every.
As shown in Fig. 1 ~ 3, the downside of the end seal 2 is connected with the side end face of oil sealing main body 1, the end seal
At least two point-like contacts portions 21 are provided with 2 upper side.Set point-like contact site 21 that end seal 2 can be made to be squeezed
When, it can preferably deform, realize more preferable axial static sealing effectiveness.
As shown in Fig. 1 ~ 3, set fluted in the collar wall of the oil sealing main body 1, the outer ring seal 3 is inlaid in recessed
In groove.
The oil sealing main body 1 can be made up of polytetrafluoroethylmaterial material.
The end seal 2 can be made up of elastomeric material.
The outer ring seal 3 can be O-ring seal.
As shown in Fig. 1 ~ 3, the lip 11 is provided with two or three or four, but not limited to this.
