Inner oil seal is pressed abd fixed on the inside of outer oil seal by rolling by reinforcing ring, and asphalt felt is adhered on the front end face of outer rubber body；Oil
Felt constitutes first of anti-muddy water structure, and outer seal lip pair lip constitutes the anti-muddy water structure of second, outer seal lip tetrafluoro piece master
Lip constitutes the anti-muddy water structure in third road, and interior sealing lip pair lip constitutes the 4th anti-muddy water structure, the interior main lip structure of sealing lip
At oil-leakage-prevention and the 5th anti-muddy water structure.
The utility model, the inclined-plane of the interior main lip of sealing lip are provided with unidirectional return wire, and unidirectional return wire makes interior oil rotation
When generate pump inhale and seal；The inclined-plane of the main lip of outer seal lip tetrafluoro piece is provided with the structure of bidirectional return line, is also beneficial to
The leakproofness of oil sealing.
The utility model, the rubber-coated of the outer skeleton of outer oil seal are provided with threaded line face.
The utility model, asphalt felt and hub spindle are interference fit.
The utility model, inner oil seal fill resistance to wear-resistant material based on high/low temperature fluorine nitrile rubber material in rubber, lead to
Optimization design formula is crossed, tear resistance is higher enhanced, and the temperature resistant range of fluorubber rubber is -40 DEG C ~ 250 DEG C.Outer oil
Envelope is based on hydrogenated nitrile-butadiene rubber, and the temperature resistant range of hydrogenated nitrile-butadiene rubber is -55 DEG C ~ 150 DEG C, and lip pastes polytetrafluoroethylene (PTFE), phase
It is few to the friction temperature of rubber lip, the temperature of inner oil seal is substantially reduced, the service life for improving inner oil seal is conducive to.
The beneficial effects of the utility model, asphalt felt constitute first of anti-muddy water structure, asphalt felt internal orifice dimension and hub spindle
Diameter has the magnitude of interference of 2mm, so that muddy water gear not can enter outside oil sealing, mainly prevents silt from entering outer seal lip pair lip；
Outer seal lip pair lip constitutes the anti-muddy water structure of second, and outer seal lip pair lip and hub spindle have certain magnitude of interference, so that
The muddy water for having part to leak through asphalt felt is blocked again, mainly prevents a small amount of muddy water from entering the intracavitary destruction tetrafluoro of outer oil seal type
The main lip of piece；The main lip of outer seal lip tetrafluoro piece constitutes the anti-muddy water structure in third road, function that there are two the main lips of tetrafluoro piece, and one
It is to prevent gear oil from leaking out, the other is it is intracavitary to prevent muddy water from entering oil sealing type；Interior sealing lip pair lip constitutes the 4th anti-mud
Water-bound, even if the anti-muddy water structure in front three has a small amount of muddy water to enter oil sealing type chamber, interior sealing lip pair lip also has anti-muddy water
Function；The main lip of interior sealing lip constitutes oil-leakage-prevention and the 5th anti-muddy water structure, the interior main lip one side oil-leakage-prevention of sealing lip, separately
On the one hand it is intracavitary to enter axle housing type for anti-muddy water.
The utility model, with being able to maintain, oil sealing shape itself, trace performance are excellent, the preferably anti-mud of sealing effect
The advantages of water, oil-leakage-prevention, the various oil sealings suitable for heavy dregs automobile axle hub bearing occasion.
Following example combination attached drawing is further described the utility model.
