The dust flaps of frame bottom outer, main lip are enclosed within the outside of the second skeleton, and the first skeleton top bending Formation cross-section is dust-proof in n shapes
Portion, and dust flaps are provided with dust excluder lips two of the section arranged on the inside of laminating dustproof part in in-line.
The entrance of extraneous dust etc. is prevented, while dust excluder lips two can also be offset in the horizontal direction.
In above-mentioned a kind of resistance to eccentric novel compositions oil sealing, described sealing wing inside cross-sectional is corrugated.
With housing interference fit on the inside of the sealing wing, it is ensured that do not leak.
Compared with prior art, this utility model has the advantage that：
First skeleton is played a supporting role to outer oil seal, external diameter position and housing interference fit, it is ensured that external diameter is not leaked, with
When spring lasting offer radial force is provided, main lip is contacted with inner oil seal external cylindrical surface, it is to avoid abrasion axle, it is ensured that close
Envelope medium is not leaked, and extends V-type waist using horizontal direction, with certain level extendable room, it is ensured that combination oil seal is big
Do not leak under eccentric operating mode.

Specific embodiment
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As shown in figure 1, a kind of resistance to eccentric novel compositions oil sealing of this utility model, including inner oil seal 2 and outer oil seal 1, outward
Oil sealing 1 includes that the first skeleton 11 and the first rubber bodies 12, the first rubber bodies 12 include the ala lateralis 13 for setting gradually from outside to inside
With inboard wing 14, ala lateralis 13 is enclosed within 11 top outer wall of the first skeleton, with the main lip being enclosed within inner oil seal 2 on inboard wing 14
15, there is spring groove on 14 outer wall of inboard wing at 15 back side of main lip, on spring groove, be cased with spring 16, ala lateralis 13 and inboard wing
There is in the first rubber bodies 12 between 14 V-type waist 17 of the section in inverted V-shaped, V-type waist 17 extends in the horizontal direction, and V
