The utility model discloses a structure sets up rationally, can guarantee the sealed stability of vice lip and the obvolvent of jackshaft axle, can prevent also that vice lip from taking place to warp and the excessive wear in the use, thus the technique of having solved the sealed stability of the easy wearing and tearing influence of vice lip in the conventional art less than.
Description
Technical field
The utility model belongs to oil seal technique field, and in particular to a kind of jackshaft is input into oil sealing.
Background technology
It is general in the car all to use medium bridge structure, in order to the stability in use for ensureing medium bridge structure typically all can add
Lubricating oil, while lubricating oil generation leakage needs to use jackshaft to be input into oil sealing in order to prevent jackshaft, the jackshaft of conventional art is defeated
Enter oil sealing to be mainly by rubber oil sea body, main lip and secondary lip are arranged in the centre bore of rubber oil sea body is used for bridge axle in obvolvent,
Yet with main lip and secondary lip when middle bridge axle is used due in rubber oil sea body without corresponding buffer structure, so main lip,
Frictional force between secondary lip and middle bridge axle can be larger, it is easy to main lip and secondary lip abrasion is made, so as to affect making for rubber oil sea body
It is restricted with sealing stability, applicability and practicality with the life-span.
The content of the invention
The purpose of this utility model is to provide the jackshaft input oil sealing that a kind of stability in use is good and sealing is strong, it is intended to solve
Certainly secondary lip easily weares and teares so as to affect the technical deficiency of sealing stability in conventional art.
The technical scheme for realizing the utility model purpose is a kind of jackshaft input oil sealing, including rubber oil sea body and is embedded in
Metallic framework in rubber oil sea body, is additionally provided with hollow spring, and in the centre bore of the rubber oil sea body main lip and pair are provided with
Lip, is embedded with R type skeletons in the rubber oil sea body, and laying dust groove, the product are provided with the side of the rubber oil sea body
Dirt groove is arranged on the end face towards air chamber of rubber oil sea body, and the inclination vertical edge of the R types skeleton is extended in secondary lip
And the laying dust groove is arranged at the bottom end opening of R type skeletons, the hollow spring is arranged on main lip position and described hollow
In the annulus of R type skeletons, the end of the metallic framework is fixed in the montant portion of R type skeletons spring.
The inclination vertical edge one of spherosome, the spherosome and R type skeletons is provided with the inclination vertical edge end of the R types skeleton
Body formed and described spherosome is in secondary lip.
The metallic framework bag knows montant and cross bar, and the montant and cross bar are integrally formed and are provided with the middle part of the cross bar
Arc bow portion, is embedded with Z-shaped to piece in rubber oil sea body, and the Z-shaped top surface cross bar to piece is pressed on the bottom surface in arc bow portion
On.
It is sheet metal elastomer in the tangent plane of the R type skeletons.
The utility model has positive effect：Structure setting of the present utility model rationally, in rubber oil sea body R is embedded with
Type skeleton, and the inclination vertical edge of R type skeletons extended in secondary lip, such that it is able to ensure that secondary lip is close with middle bridge axle obvolvent significantly
Envelope stability, and laying dust groove and R type skeletons are provided with, there is preferable snubber elastomeric and cushion space so as to also make secondary lip,
Can prevent secondary lip from deforming in use and excessive wear, so as to it is also ensured that service life, solves tradition
Secondary lip easily weares and teares so as to affect the technical deficiency of sealing stability in technology, and stability in use is good and seals strong.
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
