Can quickly increase, lead to seal failure and produce the problem of oil leak, provide that a kind of structure is simple, versatility is high, long service life
Bidirectional end face sealing device with good seal performance.
The purpose of this utility model can employ the following technical solutions to reach：
A kind of Bidirectional end face sealing device, the cast structural that described Bidirectional end face sealing device is spliced to form for sealing strip,
Described sealing strip includes pedestal and the lip on pedestal side, and described lip tilts to be connected with pedestal；In described sealing strip
When overturning from the top down, described lip is located at the same side of pedestal, and lip and pedestal are changed into inclination from tilting upward to be connected
Connect downwards, or lip and pedestal tilt upward connection from being connected diagonally downward to be changed into；Described sealing strip is along the circumference of rotating shaft
Directional spreding, and be fixedly installed in described rotating shaft, described lip top pressure seal face, form sealing installation structure.
As a kind of preferred scheme, the upper bottom surface of described pedestal and bottom surface have mounting groove, described mounting groove inner sleeve
By clip, pedestal is fixedly installed in described rotating shaft.
As a kind of preferred scheme, the front end of described lip is provided with profile of tooth lip, close described in described profile of tooth lip top pressure
End-blocking face.
Further, described profile of tooth lip includes tooth and lower tooth, and described upper tooth and lower tooth tilt upward respectively with downwards
Seal face described in top pressure.
As a kind of preferred scheme, described Bidirectional end face sealing device is elastomeric material or polyurethane material.
Implement this utility model, have the advantages that：
1st, sealing strip of the present utility model can carry out obverse and reverse installation, and when front is installed, lip tilts upward connection
On pedestal, this kind of structure is applied to the less use environment of internal oil liquid pressure；And when internal oil liquid pressure is larger, can be by
Sealing strip upset carries out reverse side installation, and now, lip is connected on pedestal diagonally downward.Internally oil liquid pressure acts on lip
When, due to being limited by the restriction of lip length, lip is swung up and is pressed on seal face so that lip top pressure is in close
The active force in end-blocking face increases and ensures the reliability sealing, thus improve the performance of pressure-bearing, has that structure is simple, versatility
The high feature with good seal performance.
2nd, each tooth of profile of tooth lip of the present utility model can carry out multi-stage sealed, the effect of raising sealing, and each tooth
Between can store a certain amount of lubricating oil, rotating shaft drive Bidirectional end face sealing device rotate during, profile of tooth lip with close
Being lubricated between end-blocking face, thus reducing the rate of wear of profile of tooth lip, being improved the performance and used life of sealing.
Brief description
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of this utility model prior art；
Fig. 2 is the front scheme of installation of this utility model Bidirectional end face sealing device；
Fig. 3 is the reverse side scheme of installation of this utility model Bidirectional end face sealing device.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Embodiment
With reference to Fig. 2 and Fig. 3, the present embodiment is related to sealing device, and described Bidirectional end face sealing device splices shape for sealing strip
The cast structural becoming, described sealing strip includes pedestal 1 and the lip 2 on pedestal 1 side, and described lip 2 and pedestal 1 tilt
Connect；When described sealing strip overturns from the top down, described lip 2 is located at the same side of pedestal 1, and lip 2 and pedestal 1 are from inclining
Oblique upper (lower) connection be changed into diagonally downward (on) connect；Described sealing strip is along the circumferencial direction distribution of rotating shaft, and fixing peace
It is loaded in described rotating shaft 3, described lip 2 top pressure seal face 4, form sealing installation structure.The sealing strip of this structure can be carried out
Obverse and reverse is installed, and when front is installed, lip 2 tilts upward and is connected on pedestal 1, and this kind of structure is applied to interior oil hydraulic pressure
The less use environment of power；And when internal oil liquid pressure is larger, sealing strip upset can be carried out reverse side installation, and now, lip 2
It is connected to diagonally downward on pedestal 1.When internally oil liquid pressure acts on lip 2, due to being limited by the restriction of lip 2 length,
Lip 2 is swung up and is pressed on seal face 4 so that lip 2 top pressure ensures in the active force increase of seal face 4
The reliability of sealing, thus improve the performance of pressure-bearing, has the characteristics that structure is simple, versatility is high and good seal performance.
The upper bottom surface of described pedestal 1 and bottom surface have mounting groove 11, and described mounting groove 11 inner sleeve passes through clip by pedestal 1
It is fixedly installed in described rotating shaft 3.When front or back is installed, sealing strip is spliced along the circumferencial direction distribution of rotating shaft 3
Become cast structural, and by clip banding in described rotating shaft 3, facilitate the dismounting of sealing strip and installation so that sealing strip from
Just (anti-) face installs that to be changed into anti-(just) face easier for installation and quick.
The front end of described lip 2 is provided with profile of tooth lip 21, seal face 4 described in described profile of tooth lip 21 top pressure.This profile of tooth
A certain amount of lubricating oil can be stored between each tooth of lip 21, drive the process of Bidirectional end face sealing device rotation in rotating shaft 3
In, being lubricated between profile of tooth lip 21 and seal face 4, thus reducing the rate of wear of profile of tooth lip 2, being improved sealing
Performance and used life.
Described profile of tooth lip includes tooth and lower tooth, and described upper tooth and lower tooth tilt upward close with described in downward top pressure respectively
End-blocking face.Upper tooth plays the effect stopping external dust, and lower tooth then plays the effect preventing internal lubrication oil (oily) from revealing, tool
There is the effect of two resealings.
Described Bidirectional end face sealing device is elastomeric material or polyurethane material.Certainly, other is similar to rubber or poly- ammonia
The material that ester material has preferable toughness is also applied for Bidirectional end face sealing device.
A kind of above disclosed only preferred embodiment of this utility model, can not limit this practicality with this certainly
New interest field, the equivalent variations therefore made according to this utility model claim, still belong to what this utility model was covered
Scope.
