Mostly present gear ring oil sealing is the monomer sealing means, and it exists certain magnitude of interference to cause running shaft in rotary course, to rub mutually with lip because of between lip and the running shaft, has a strong impact on the working life of oil sealing; Though the gear ring oil sealing of the disclosed non-monomer structure of few part is arranged now, all not ideal enough because of its sealability and working life, can't satisfy the needs of actual conditions.
The model utility content
The utility model provides a kind of combined type PTFE gear ring oil sealing, and it can overcome the existing problem of present gear ring oil sealing, has good sealing effect and long working life.
The technological scheme that the utility model adopted is:
Combined type PTFE gear ring oil sealing comprises the outer oil seal that is combined each other by outer skeleton and external sealed body, and the inner oil seal that is combined each other by inner frame and interior seal; Seal is sleeved on the inboard of outer skeleton in said; Sealing lip and dust excluder lips in said on seal and the external sealed body form double layer construction arranged side by side vertically; Its lip place of sealing lip in said on the seal is provided with the PTFE sheet.
In the technological scheme of the utility model, also have following additional technical feature:
The excircle of said outer skeleton is provided with circular porous structure.
The axial cross section of said outer skeleton is a S shape.
The back side of the sealing lip of said inner oil seal and outer oil seal is equipped with groove, is equipped with spring in the said groove.
Be provided with lithium grease between said sealing lip.
Seal and inner frame and external sealed body are integrated composite structure with outer skeleton in said.
Seal adopts nitrile rubber in said, and said external sealed body adopts fluorine rubber.
Compared with prior art, the advantage and the good effect of the utility model are: the combined type PTFE gear ring oil sealing of the utility model, it can overcome the existing problem of present gear ring oil sealing, has the high advantage of good sealing effect, long service life and reliability.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described further:
Fig. 1 is its sectional view of combined type PTFE gear ring oil sealing of the utility model;
