Background technique
If rolling bearing uses in rugged environment, bearing sealed ring and seal closure are essential, because it
Can prevent dirt from invading, extend bearing life.Roll in milling train is usually by four column sealing tapered roller bearing supports.It uses
Shi Yaoqiu bears the intrusion of strong impact load, water and clast.But bearing is under harsh lubricating condition, existing bearing
It is long, easy to maintain that sealing is difficult to realize dust-proof, water, the intrusion of clast and high reliablity, service life.
Experience have shown that bearing is invaded vulnerable to clast and is polluted in the case where polluting operating condition.In pollution or edge lubricating condition
Under bearing life can by improve bearing steel microstructure improve.The negative pressure generated in bearing can cause water from primary seal
Intrusion, the structure of sealing have a significant impact to negative pressure.Therefore, reducing the negative pressure in bearing is the basic demand for preventing water from entering.
Most efficient method be make hole sealing it is not direct contacted with water, while retaining holes seal original function-prevent water and dirt from
The intrusion of roll neck side.
So being now badly in need of a kind of roll neck tapered roller bearing inner diameter seal structure, solve in pollution or lack of lubrication item
The short problem of bearing life under part.
Utility model content
The purpose of the utility model is to provide a kind of roll neck tapered roller bearing inner diameter seal structure, solve in pollution or
The short problem of bearing life under the conditions of lack of lubrication.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of roll neck of the utility model tapered roller bearing inner diameter seal structure, including flexible sealing body and it is mounted to institute
State the rigid backbone on seal outer ring；The skeleton includes vertical part and the horizontal part, one end of the vertical portion and the water
The one end in flat portion is connected；The seal includes main part, left stopper and right stopper, and the left stopper is arranged in the main body
On the left of portion outer ring, the right stopper is arranged on the right side of the main part outer ring；The cross section of the right stopper be it is ladder-like, it is described
The cross section of left stopper is vertical bar shape, and the free end of left stopper offers the first inclined-plane, institute is accommodated between left stopper and right stopper
State skeleton；The left and right ends of the main part offer the second inclined-plane；The inner ring of the main part is axially disposed have it is multiple convex
Circle.
Further, the cross sectional shape of the flange collar is semicircle or triangle.
Further, the cross sectional shape of the flange collar is right angled triangle.
Further, the section right angle of the flange collar is in inner ring.
Further, the quantity of the flange collar is two.
Further, the angle of first inclined-plane and vertical plane is 30 °.
Further, the angle of second inclined-plane and vertical plane is 60 °.
Further, the vertical part and the horizontal part is integrally formed.
Further, the main part, left stopper, right stopper and flange collar are integrally formed.
Compared with prior art, the advantageous effects of the utility model are as follows:
The outer ring of the utility model is fixed with skeleton, and skeleton is contacted with bearing inner race, wear-resisting, prolongs the service life；First
Inclined-plane is spilt skeleton is naked, is prevented seal from rubbing with bearing, is influenced the service life of the utility model；Second inclined-plane
Enhance seal intensity；After flange collar is stuck on axis, formation is multiple-sealed, and forms seal chamber between two neighboring flange collar, seals
Effect is more preferable, extends bearing service life.

Specific embodiment
As shown in Figure 1-3, a kind of roll neck specific embodiment of tapered roller bearing inner diameter seal structure, including it is flexible close
Envelope body 1 and the rigid backbone 2 being mounted on 1 outer ring of seal.Specifically, the skeleton 2 includes vertical portion 201 and level
Portion 202, one end of the vertical portion 201 are connected with one end of the horizontal part 202, the vertical portion 201 and horizontal part 202
It is integrally formed, forms whole skeleton.The seal 1 includes main part 101, left stopper 102 and right stopper 103, described
Left stopper 102 is molded on the left of 101 outer ring of main part, and it is right that the right stopper 103 is molded over 101 outer ring of main part
Side, the cross section of the right stopper 103 be it is ladder-like, the cross section of the left stopper 102 is vertical bar shape, left stopper 102 from
