Description
Technical field
This utility model relates to technical field of sealing technology, is specifically related to a kind of oil seal.
Background technology
Being illustrated in figure 1 existing oil enveloping structure, inside and outside it, sealing surface is all in straight wall, below the oil sealing existence of this kind of structure
Not enough: coordinating installation difficulty with tube element, its outer diameter must be consistent with pipe fitting diameter, and excessive installation is not entered, strongly
Installation easily causes oil sealing and damages, and too small installation is the tightst, it is impossible to seal；Big with tube element contact area, i.e. cause friction
Resistance is big, easily accelerates the abrasion of oil sealing and affects the fluidity of motion of potted component.
Utility model content
For above-mentioned deficiency, this utility model provides a kind of oil seal, have installation quickly and easily, good sealing effect,
Service life length feature.
For achieving the above object, the technical solution of the utility model is:
A kind of oil seal, including skeleton and the oil seal washer body that is coated on skeleton；The upper end of described oil seal washer body
A groove in " V " type is had on face；There is on the inwall of described oil seal washer body the sealing lip of a projection, described sealing lip by
A ramp and a lower inclined plane that described oil seal washer body extends are constituted；The outer wall bottom of described oil seal washer body has one by institute
Stating the outer seal ring that oil seal washer body extends, the external diameter of described outer seal ring is more than the external diameter of described oil seal washer body；Outside described
Between upper surface and the outer wall of described oil seal washer body of sealing ring, there is an intermediate incline.
Further, the height of described outer seal ring is the 1/3 of described oil seal washer body height.
Further, the exterior angle, upper surface of described oil seal washer body is chamfering structure.
Improving as one, the outer surface of described outer seal ring and described sealing lip is coated with polytetrafluorethylecoatings coatings.
The beneficial effects of the utility model are:
The outer wall of oil sealing of the present utility model uses size outside diameter structure, first loads from miner diameter end when mounted, then will be big
Footpath side pressure enters, convenience quick for installation, and will not damage oil seal washer；Oil sealing of the present utility model works with outer seal ring for external seal
Face, being interior sealed working face with sealing lip, little with potted component contact area, frictional resistance is little, advantageously reduces the mill of oil sealing
Loss rate and raising potted component fluidity of motion；It is coated with polytetrafluorethylecoatings coatings on outer seal ring and sealing lip simultaneously, permissible
Improve its wearability and self-lubricity, increase the service life.

Fig. 2 is oil enveloping structure schematic diagram of the present utility model.
Detailed description of the invention
Embodiment:
As in figure 2 it is shown, a kind of oil seal, including skeleton (1) and the oil seal washer body (2) that is coated on skeleton；Described
A groove (3) in " V " type is had on the upper surface of oil seal washer body (2)；One is had on the inwall of described oil seal washer body (2)
Protruding sealing lip (4), a ramp (41) that described sealing lip (4) is extended by described oil seal washer body (2) and a lower inclined plane
(42) constitute；The outer wall bottom of described oil seal washer body (2) has an outer seal ring (5) extended by described oil seal washer body,
The external diameter of described outer seal ring (5) is more than the external diameter of described oil seal washer body (2)；The upper surface of described outer seal ring (5) and institute
State and there is between the outer wall of oil seal washer body (2) intermediate incline (6).
Further, the height of described outer seal ring (5) is the 1/3 of described oil seal washer body (2) height.
Further, the exterior angle, upper surface of described oil seal washer body (2) is chamfering structure.
Improving as one, the outer surface of described outer seal ring (5) and described sealing lip (4) is coated with politef
Coating (not shown).
The above is preferred implementation of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and profit
Decorations are also considered as protection domain of the present utility model.
