At the gap and outside of main lip is provided with elastomeric element；The inside of first skeleton and the second skeleton is provided with the first reinforcement.
Further, the lateral lip, the second skeleton, main lip, the first skeleton and the first annular groove are made up of elastomeric material.
Further, first skeleton and the second skeleton are two L-type sealing frameworks.
Further, first reinforcement is Z-type stairstepping.
Further, the first detent and the second detent are further respectively had on first skeleton and the second skeleton.
Further, described being located on the first reinforcement of the second skeleton part is additionally provided with the second reinforcement.
Further, first reinforcement and the second reinforcement are made up of ferrous material.
Beneficial effect：Compared with prior art, the present invention has advantages below：
Made using the material of rubber, constitute dynamic and static sealing surface, the speciality with elasticity and sealing；
Using the design of reinforcement, especially with reinforcement made by ironware so as to which basic framework increases rigidity makes oil
Envelope will not deform easily；
Using the design of elastomeric element part, there is provided the certain binding force of oil sealing lip and prolongation oil sealing life-span；
Using the design for increasing by the second skeleton, the quantity of static seal surface is increased so that the steadiness of whole oil seal
Can be more preferably；
Using the design for increasing by the second reinforcement, the support performance of the skeleton of peripheral hardware second is increased so that oil sealing is more steady
Gu；
Using the first annular groove part, elastic angle is provided for lateral lip, increase the sealing effectiveness of lateral lip part
Using the design of main lip and lateral lip, the quantity of dynamic sealing surface is increased, increased the sealing property of oil seal.
