Seal the sealing ring of connection；Sealing ring is equipped with the sealing lip of the end face at end where one end is pressed against outer ring inner hole big end；Inner ring, taper
Lubricating cavity is constituted between roller big end, outer ring and sealing ring.The tapered roller bearing of the big end sealing is in use, be equipped with close
One end of seal is opposite with harsh environment, makes dust, mud not and can enter the tapered roller bearing of big end sealing；It is filled in lubricating cavity
Be conducive to the lubricating grease of lubrication；The tapered roller bearing of big end sealing is suitble to the harsh environment with dust, mud to use, and
Service life is longer.
Preferably, the sealing ring includes：By end circle, set on end circle one end inner ring and with outer ring inner hole big end institute
The skeleton that opposite outer ring is constituted in the end face at end envelopes the elastomer of outer ring and the end circle other end；The other end of sealing lip
It is integrally formed and connect with elastomer；The big end of inner ring is equipped with isometrical section be interference fitted with the inner hole of inner ring.By end circle, it is set to end
It is higher that the skeleton that the inner ring and the outer ring opposite with the end face at end where the inner hole big end of outer ring for enclosing one end are constituted has sealing ring
Strength and stiffness, elastomer be conducive to improve sealing performance；The big end of inner ring is equipped with isometrical with the inner hole of inner ring interference fit
Section, improves leakproofness and sealing ring is easy to assembly.
Preferably, the shape of the sealing lip is the frustum type circle that big end is located at sealing lip one end；Frustum type circle
Cone angle is 80 degree to 100 degree.Take into account the end face for being conducive to end where sealing lip deforms and is pressed against outer ring inner hole big end and have compared with
The big power that compresses improves leakproofness.
Compared with prior art, the utility model has the beneficial effects that：The tapered roller bearing of big end sealing is suitble to have
There is the harsh environment of dust, mud to use, and service life is longer.By end circle, set on end circle one end inner ring and in outer ring
The skeleton that the opposite outer ring in the end face at end where the big end of hole is constituted makes sealing ring strength and stiffness with higher, and elastomer is conducive to
Improve sealing performance；The big end of inner ring is equipped with isometrical section be interference fitted with the inner hole of inner ring, improves leakproofness and sealing ring fills
With convenient.The cone angle of frustum type circle is 80 degree to 100 degree, takes into account conducive to sealing lip deformation and is pressed against where the inner hole big end of outer ring
The end face at end and have the biggish power of compressing improve leakproofness.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model.
In figure：Inner ring 1, outer ring 2, conical roller 3, retainer 4, sealing ring 5, sealing lip 6, lubricating cavity 7, end circle 8, inner ring
9, outer ring 10, skeleton 11, elastomer 12, isometrical section 13.
Specific embodiment
The utility model is described further shown in reference to the accompanying drawing.
As shown in Fig. 1：A kind of tapered roller bearing of big end sealing, including：Inner ring 1, outer ring 2, set on inner ring 1 and outside
Multiple conical rollers 3 and retainer 4 between circle 2 are sheathed on the sealing ring 5 that 1 big end of inner ring is outer and is tightly connected with inner ring 1；
Sealing ring 5 is equipped with the sealing lip 6 of the end face at end where one end is pressed against 2 inner hole big end of outer ring；Inner ring 1,3 big end of conical roller,
