The utility model discloses a structure sets up rationally, makes main lip and vice lip have certain shock -absorbing capacity respectively, also can cushion certain friction pressure to improve sealed stability and life, solved in the conventional art vice lip and held easy tear and cause the technique of oil leak not enough.
Description
Technical field
The utility model belongs to oil seal technique field, and in particular to a kind of double hollow spring type retarder oil sealings.
Background technology
Retarder is a kind of conventional structure, in order to ensure the stability in use and service life of retarder, typically all can
Lubricating fluid is provided with retarder, in order to prevent lubricating fluid from leaking, typically oil sealing can be installed on retarder, conventional art
Retarder oil sealing is mainly made up of oil seal body and oil tight skeleton, and in the embedded oil seal body of oil tight skeleton, oil seal body is provided with centre bore,
Center hole wall is provided with the main lip of connecting rod inclusion and secondary lip, after oil sealing pair lip coordinates with connecting rod, causes connecting rod and oil tight skeleton
Between sizing material it is very few, so as to produce larger frictional force, easily cause the tear of secondary lip and cause oil leak, making for retarder can be affected
Use stability.
The content of the invention
The purpose of this utility model is to provide a kind of structure setting rationally and seals the strong double hollow spring type of stability to be delayed
Fast device oil sealing, it is intended to solve secondary lip in conventional art and easily tear the technical deficiency for causing oil leak.
The technical scheme for realizing the utility model purpose is a kind of double hollow spring type retarder oil sealing, including rubber oil sea
Body and the metallic framework being embedded in rubber oil sea body, are provided with main lip and secondary lip, also in the centre bore of the rubber oil sea body
It is provided with main hollow spring stack and secondary hollow spring stack, the position of the hollow spring stack of the master is engaged with main lip position, the pair
The position of hollow spring stack is engaged with secondary lip position, and m shape cushioning frames, the main sky are additionally provided with the rubber oil sea body
Heart spring stack and secondary hollow spring stack be respectively in two depressed parts of m shape cushioning frames and m shape cushioning frames two arcs
Shape projection is respectively in main lip and secondary lip, and one end of the m shapes cushioning frame is weldingly fixed on the end of metallic framework.
The metallic framework includes integrally formed montant portion and cross bar portion, n shapes is provided with the middle part of the cross bar portion and is delayed
Punching is raised, and Z-shaped buffering support rod is embedded with the rubber oil sea body, and the top cross bar of the Z-shaped buffering support rod is pressed on n shapes and delays
The top cross bar end of lobed interior and Z-shaped buffering support rod is rushed towards m shape cushioning frames side.
The m shapes cushioning frame is sheet metal body.
The felt layers by viscose glue cementation are provided between the main lip and secondary lip.
The utility model has positive effect：Structure setting of the present utility model rationally, is provided with two hollow spring stacks
With m shape cushioning frames, so that main lip has respectively certain shock-absorbing capacity with secondary lip, main lip, secondary lip seal can be not only made
Obvolvent is on retarder main shaft, while certain friction pressure can also be buffered, so as to improve sealing stability and service life,
Easily tear causes the technical deficiency of oil leak to solve in conventional art secondary lip, strong applicability and practicality is good.
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 double hollow spring type retarder oil sealings, including rubber oil sea body 1 and be embedded in rubber oil sea body 1
Metallic framework 2, main lip 3 and secondary lip 4 are provided with the centre bore of the rubber oil sea body 1, be additionally provided with the hollow He of spring stack 5 of master
Secondary hollow spring stack 6, the position of the hollow spring stack 5 of the master is engaged with the position of main lip 3, the position of the secondary hollow spring stack 6
Put and be engaged with the position of secondary lip 4, be additionally provided with m shapes cushioning frame 7 in the rubber oil sea body 1, the hollow He of spring stack 5 of the master
Secondary hollow spring stack 6 is respectively in two depressed parts of m shapes cushioning frame 7 and two arc convex of m shapes cushioning frame 7 divide
In main lip and secondary lip, one end of the m shapes cushioning frame 7 is weldingly fixed on the end of metallic framework 2 in other places.It is provided with two skies
Heart spring stack and m shape cushioning frames so that main lip has respectively certain shock-absorbing capacity with secondary lip, not only can make main lip,
Secondary lip seal obvolvent is on retarder main shaft, while certain friction pressure can also be buffered, so as to improve sealing stability and
Service life.
The metallic framework 2 includes integrally formed montant portion 21 and cross bar portion 22, sets at the middle part in the cross bar portion 22
There is n shapes buffering raised 23, in the rubber oil sea body 1 Z-shaped buffering support rod 8, the top cross bar of the Z-shaped buffering support rod are embedded with
The top cross bar end of n shapes buffering lobed interior and Z-shaped buffering support rod is pressed on towards m shape cushioning frames side.By Z-shaped slow
Offset bar can make the metallic framework also function with certain compensator or trimmer pressure, can prevent from causing between connecting rod and oil tight skeleton
