Description
Technical field
The utility model belongs to oil seal technique field, and in particular to a kind of main tooth oil sealing.
Background technology
With the fast development of China's mechanical industry, the also more and more higher of the requirement to hermetic oil seal, the sealing of conventional art
Oil sealing is mainly made up of interior sealing body, external seal body, skeleton, spring, sealing lip and dust excluder lips, its interior sealing body and external seal
Body mainly adopts fluorubber, installs on oil sealing by skeleton and with the interference fit between encapsulation, can produce when in use larger
Frictional force, although it can realize oil sealing, its oil sealing sealing is poor, also easily occur when using for a long time permeability or
The phenomenon of oil leak, so the service life of oil sealing can be affected to a certain extent.
The content of the invention
The purpose of this utility model is for a kind of good and practical main tooth oil sealing of stability in use, it is intended to solve tradition
Oil sealing long-time uses the technical deficiency for seepage or oil leak easily occur in technology.
The technical scheme for realizing the utility model purpose is a kind of main tooth oil sealing, including main oil seal body and secondary oil seal body,
Be provided with main oil tight skeleton in the main oil sealing body, be provided with secondary oil tight skeleton in the secondary oil sealing body, the main oil tight skeleton with
The secondary oil tight skeleton is connected, and main lip is equipped with the main oil seal body and secondary oil seal body, in the bottom of the main oil seal body
Secondary lip is provided with, arc spring lamination is provided with the main oil sealing body, the end of the main oil tight skeleton is pressed on the arc of arc spring lamination
Shape crowning medium position, the two ends of the arc spring lamination are respectively at the main lip of main oil seal body and secondary lip position, in the pair
Oval buffering ring body is provided with oil sealing body, the oval buffering ring body is arranged on the main lip of secondary oil tight skeleton and secondary oil seal body
Between.
It is equipped with the two ends of the arc spring lamination and compresses plate body, the end of the arc spring lamination is fixed on and compresses plate body
Middle part.
Groove is provided with the end face of the main oil seal body, the groove is arranged on the air contact surfaces of main oil seal body.
Hollow spring is additionally provided with, the hollow spring is arranged on main oil seal body and secondary oil seal body.
The utility model has positive effect：Structure setting of the present utility model rationally, in main oil sealing body arc is provided with
Shape shell fragment, thereby may be ensured that main lip on main oil seal body and secondary lip compresses stress, thereby may be ensured that the stability of oil sealing, together
Shi Caiyong arc spring laminations make it have certain cushion effect, so make secondary lip be not easy larger frictional force occur, so as to have
The abrasion that the reduction of effect is caused because of frictional force, can improve to a certain extent service life, when solving that oil sealing is long in conventional art
Between using the technical deficiency for seepage or oil leak easily occur, 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 main tooth oil sealing, including main oil seal body 1 and secondary oil seal body 2, in the main oil seal body 1 main oil is provided with
Envelope skeleton 3, in the secondary oil seal body 2 secondary oil tight skeleton 4 is provided with, and the main oil tight skeleton 3 is connected with the secondary oil tight skeleton 4
Connect, on the main oil seal body 1 and secondary oil seal body 2 main lip 5 is equipped with, secondary lip 6 is provided with the bottom of the main oil seal body 1, in institute
State in main oil seal body 1 and be provided with arc spring lamination 7, the end of the main oil tight skeleton 3 is pressed in the arc convex face of arc spring lamination 7
Portion position, the two ends of the arc spring lamination 7 are respectively at the main lip of main oil seal body 1 and secondary lip position, in the secondary oil seal body 2
Be provided with oval buffering ring body 8, the oval buffering ring body 8 be arranged on secondary oil tight skeleton 4 and secondary oil seal body 2 main lip it
Between.
It is equipped with the two ends of the arc spring lamination 7 and compresses plate body 9, the end of the arc spring lamination is fixed on and compresses plate body
Middle part.Using plate body is compressed, such that it is able to prevent arc spring lamination end from damaging main oil seal body.
Groove 10 is provided with the end face of the main oil seal body 1, the groove is arranged on the air contact surfaces of main oil seal body.
Can prevent dust from entering in main oil seal body.
Hollow spring 11 is additionally provided with, the hollow spring is arranged on main oil seal body and secondary oil seal body.
