The utility model has the advantages of: the characteristics that have combined radial oil blanket and axial oil blanket seal the axle and with axial vertical's plane, have the dustproof effect of preferred.
Description
Technical field
The invention belongs to mechanical organ technical field, more particularly to a kind of two-lip seal sealing device.
Background technology
The sealing of oil sealing, i.e. lubricating oil.Sealing device is to prevent the joint portion of fluid or solid particle from device
Reveal and prevent impurity such as dust, moisture, greasy dirt etc. of outside from invading the material of the parts of the inside of plant equipment in position
Or part, for oil pocket and extraneous isolation, internal oil sealing to be externally dust-proof.It is widely used in：Household electrical appliance, automobile are sent out
In numerous industries such as motivation, chemical industry, it is usually used at the bearing of various machineries, particularly rolling bearing position.Dust is penetrated into, not only
Abradable seal member, and can greatly wear and tear fairlead and piston rod, impurity enter hydraulic medium in, also can affect operation valve and
The function of pump, in the worst case, may also damage these devices.
The content of the invention
Goal of the invention：The present invention provides a kind of two-lip seal sealing device, using the design for setting up lateral lip, combines radially
The characteristics of oil sealing and axial seal come seal shaft and with axially vertical plane, it is existing to solve with preferably dust-proof effect
Sealing effectiveness is not good in technology causes impurity to enter the problem in hydraulic medium.
Technical scheme：For achieving the above object, the technical solution used in the present invention is：
A kind of two-lip seal sealing device, with skeleton, the skeleton is provided with：Lip rubber, reinforcement, spring, side
Lip and the first annular groove；The lip rubber and the first annular groove are arranged in the plane of the sealing surface of skeleton, and lateral lip is arranged on
The bottom of one annular groove, the gap on the opposite of the sealing surface of the skeleton is provided with spring.
Further, the reinforcement is the metal parts of L-type.
Further, the opening direction of the lip rubber is to extend to the outside of skeleton.
Further, axis direction of the opening direction of the lateral lip towards skeleton.
Further, the lateral lip is made up of quality of rubber materials.
Further, detent is additionally provided with skeleton.
Beneficial effect：Compared with prior art, the present invention has advantages below：
Using lip rubber part, with elastic nature, there is goodish sealing effectiveness to axle；
Using reinforcement part, increasing rigidity in the basic framework of two-lip seal sealing device makes oil sealing not become easily
Shape；
Using spring members, there is provided the certain binding force of oil sealing lip and prolongation oil sealing life-span；
Using the first annular groove part, elastic angle is provided for lateral lip, increase the sealing effectiveness of lateral lip part；
Using lateral lip part, seal shaft and with axially vertical plane, there is provided preferable dust reduction capability.
Description of the drawings

Specific embodiment
A kind of two-lip seal sealing device, with skeleton 5, the skeleton 5 is provided with：Lip rubber 1, reinforcement 2, spring
3rd, the annular groove 7 of lateral lip 4 and first；The annular groove 7 of the lip rubber 1 and first is arranged in the plane of the sealing surface of skeleton 5, lateral lip 4
The bottom of the first annular groove 7 is arranged on, the gap on the opposite of the sealing surface of the skeleton 5 is provided with spring 3.Using lip rubber
1 part, with elastic nature, there is goodish sealing effectiveness to axle；Using spring members, there is provided the certain binding force of oil sealing lip
And extend the oil sealing life-span；
Aforesaid two-lip seal sealing device, the reinforcement 2 is the metal parts of L-type.Preferably use the materials such as iron and steel
Material is made.Using reinforcement part, increasing rigidity in the basic framework of two-lip seal sealing device makes oil sealing not become easily
Shape；
Aforesaid two-lip seal sealing device, the opening direction of the lip rubber 1 is to extend to the outside of skeleton 5；Lateral lip 4
Opening direction towards skeleton 5 axis direction.I.e. lip rubber 1 and lateral lip 4 are rightabout, on the sealing surface of skeleton 5
In being symmetrically extended.
Aforementioned lateral lip 4 is made up of quality of rubber materials.Using the first annular groove part, elastic angle is provided for lateral lip, increase lateral lip
The sealing effectiveness of part；Using lateral lip part, seal shaft and with axially vertical plane, there is provided preferable dust reduction capability.
Aforesaid two-lip seal sealing device, is additionally provided with detent 6 on skeleton 5, for fixing skeleton 5.
The present invention is further described with reference to embodiment.
As shown in figure 1, for oil sealing of the present invention along axis profile, Fig. 2 is the partial enlarged drawing of section.This design
The characteristics of combining radial direction oil sealing and axial seal come seal shaft and with axially vertical plane, with preferably dust-proof effect.
Lip rubber 1, with elastic nature, there is goodish sealing effectiveness to axle；
Reinforcement 2, basic framework increases rigidity makes oil sealing not deform easily；
Spring 3, there is provided the certain binding force of oil sealing lip and prolongation oil sealing life-span；
Lateral lip 4, seal shaft and with axially vertical plane, there is provided preferable dust reduction capability.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
