Abstract
The utility model discloses a rotatory high pressure oil seal of retarber, including oil seal and the oil seal framework of embedding in oil seal, be equipped with the centre bore at oil seal's center, be equipped with on the pore wall of centre bore with the main lip and vice lip of connecting rod obvolvent, still the embedding has the tangent plane to be the oval -shaped ring body in oil seal, the ring body sets up with the centre bore heart, oil seal framework's end connection is at the lateral surface center of ring body, is equipped with respectively to the post at oval -shaped ring body long limit both ends, supports the position of post and cooperatees with main lip and vice lip position respectively. The utility model discloses a structure sets up rationally, can effectively avoid vice lip probably to have tearing problem because of frictional force when guaranteeing the oil blanket leakproofness, solved the conventional art in the vice lip of oil blanket lead to the fact tearing technique not enough when using easily, the stability in use well and the suitability strong.
Description
Technical field
The utility model belongs to oil seal technique field, and in particular to a kind of retarder rotary high pressure oil sealing.
Background technology
Retarder, in order to prevent oil leak, typically can all be provided with oil sealing built with damping oil in retarder, oil sealing is located at and connects
Between bar and outer tube, retarder axially forces tight guide cylinder and cylinder barrel, the retarder oil sealing master of prior art by oil sealing transmission
If being made up of oil seal body and oil tight skeleton, in the embedded oil seal body of oil tight skeleton, oil seal body is provided with centre bore, sets on the hole wall of center
There are the main lip that connecting rod is included and secondary lip, after oil sealing pair lip coordinates with connecting rod, cause the sizing material mistake between connecting rod and oil tight skeleton
It is few, so as to produce larger frictional force, secondary lip tear is easily caused, so as to oil leak can be caused, so as to affect to a certain extent
Its applicability and practicality.
The content of the invention
The purpose of this utility model is to provide that a kind of stability in use is good and retarder rotary high pressure oil sealing of strong applicability,
Aim to solve the problem that the pair lip of oil sealing in conventional art easily causes when in use the technical deficiency of tear.
The technical scheme for realizing the utility model purpose is a kind of retarder rotary high pressure oil sealing, including oil seal body and embedded
Oil tight skeleton in the oil sealing body, at the center of the oil seal body centre bore is provided with, and is set on the hole wall of the centre bore
Have main lip with connecting rod obvolvent and secondary lip, it is oval ring body that tangent plane is also embedded with the oil sealing body, the ring body with
Centre bore heart is arranged, and the end of the oil tight skeleton is connected to the lateral surface center of ring body, long in the oval ring body
While being respectively arranged at two ends with to post, the position to post is engaged respectively with main lip with secondary lip position.
Arc partial pressure block is provided with the end to post, it is described to be fixed in the arc-shaped recess portion of arc partial pressure block to post
Heart position.
The annular groove concentric with centre bore is provided with the end face of the oil seal body, the annular groove is arranged on oil seal body towards sky
On the end face of air cavity.
The ring body of the oval ring is sheet thin metal ring body.
The utility model has positive effect：Rationally, it is provided with ring body to structure setting of the present utility model, when in use
Oil tight skeleton is pressed on the lateral surface of ring body, while ring body is arranged into ovalisation, it has certain pooling feature, so can
To reduce the frictional force between the main lip of oil sealing, oil sealing pair lip and connecting rod, pair can be prevented effectively from while oil sealing sealing is ensured
Lip there may be the problem of tear because of frictional force, solves oil sealing pair lip in conventional art and easily causes tear when in use
Technical deficiency, stability in use is good and strong applicability.
Description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below according to specific embodiment and with reference to attached
Figure, is described in further detail to the utility model, wherein：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model
Figure.
See Fig. 1, a kind of retarder rotary high pressure oil sealing, including oil seal body 1 and the oil sealing bone being embedded in the oil seal body 1
Frame 2, at the center of the oil seal body 1 centre bore 3 is provided with, and the main lip 4 with connecting rod obvolvent is provided with the hole wall of the centre bore 3
With secondary lip 5, it is oval ring body 6 that tangent plane is also embedded with the oil seal body 1, and the ring body 6 sets with the heart of centre bore 3
Put, the end of the oil tight skeleton 2 is connected to the lateral surface center of ring body 6, in the long side two ends difference of the oval ring body 6
It is provided with to post 7, the position to post 7 is engaged respectively with main lip 4 with the secondary position of lip 5.
Arc partial pressure block 8, the arc-shaped recess portion that arc partial pressure block is fixed on to post are provided with the end to post 7
Center.It is on the arc convex of arc partial pressure block with secondary lip in main lip, so the pressure that it is subject to can be disperseed, so as to
Frictional force can be reduced to a certain extent.
Be provided with the annular groove 9 concentric with centre bore on the end face of the oil seal body, the annular groove be arranged on oil seal body towards
On the end face of air chamber.Anti-dust performance can be improved.
The ring body of the oval ring is sheet thin metal ring body.
Rationally, it is provided with ring body to structure setting of the present utility model, and when in use oil tight skeleton is pressed on the outside of ring body
Face, while ring body is arranged into ovalisation, it has certain pooling feature, so the main lip of oil sealing, oil sealing pair lip can be reduced
Frictional force between connecting rod, can be prevented effectively from secondary lip and tear is there may be because of frictional force while oil sealing sealing is ensured
Problem, solve the technical deficiency that the pair lip of oil sealing in conventional art easily causes when in use tear, stability in use it is good and
Strong applicability.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need to give all of embodiment
It is exhaustive.And these belong to obvious change that connotation of the present utility model extends out or variation still falls within this practicality
New protection domain.
