It is mutually close, so the contact dynamics that can make secondary lip declines, so as to when with insertion axle obvolvent easily to crimp in groove, from
And the sealing effectiveness of secondary lip can be affected, applicability and practicality are restricted.
The content of the invention
The purpose of this utility model is to provide the insertion axle output oil seal that a kind of stability in use is good and sealing is strong, it is intended to
Conventional art is solved because of the fluted technical deficiency so as to secondary lip seal can be affected.
The technical scheme for realizing the utility model purpose is a kind of insertion axle output oil seal, including rubber oil sea main body and oil
Envelope skeleton, the oil tight skeleton is embedded in rubber oil sea main body, is provided with the center bore inner wall of the rubber oil sea main body
Main lip and secondary lip, are provided with dust arrest groove on the side in the rubber oil sea main body with air contact, the dust arrest groove with
Centre bore is arranged concentrically, and the dust arrest groove is engaged with secondary lip position, and in the rubber oil sea main body reverse V-shaped shell fragment is embedded with
Skeleton, the outboard end of edge and reverse V-shaped shell fragment skeleton that the reverse V-shaped shell fragment skeleton is arranged on dust arrest groove extends to secondary lip
Interior, the reverse V-shaped medial extremity of shell fragment skeleton is welded and fixed with the end of oil tight skeleton, is embedded with the rubber oil sea main body
The shape sheet web frame consistent with main lip shape, it is interior and sheet web frame that the sheet web frame is embedded in main lip
One end is fixedly connected by even muscle with oil tight skeleton.
Hollow spring cylinder is additionally provided with, the main lip is pressed on hollow spring cylinder, the sheet web frame is arranged
Between hollow spring cylinder and main lip.
Protruding circular ring, the protruding circular ring and rubber oil sea main body one are provided with the side of the rubber oil sea main body
It is molded and the protruding circular ring is arranged on same side with the dust arrest groove, it is recessed that the protruding circular ring is arranged on the dust
The outside of groove.
The oil tight skeleton is L-type skeleton.
The utility model has positive effect：Rationally, it is provided with reverse V-shaped shell fragment bone to structure setting of the present utility model
Frame, deforms upon when with insertion axle obvolvent such that it is able to reduce secondary lip to dust arrest groove, thereby may be ensured that the sealing of secondary lip
Stability, while also be provided with the sheet web frame consistent with main lip shape at main lip, so as to it is also ensured that main lip with pass through
The sealing stability of axis obvolvent, solves conventional art because of the fluted technical deficiency so as to affect secondary lip seal, makes
With good stability and strong applicability.
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：
