Abstract
The utility model relates to cylinder roller bearing technical field, specifically a kind of combined type pressure stabilizing seals bearing.The bearing includes outer ring, rolling element, Spring Card collar, rubber seal, dust seal cover, sealing inner ring；Rubber seal uses axially and radially three-layer sealed structure, including radial seal lip, axial seal lip, inside additional seal lip；Dust seal cover upper end is the dust-proof flange of outer diameter, dust seal cover internal diameter is three sections of stepped constructions, and dust seal cover outer end face is three sections of stepped constructions, and dust seal cover inner face is three sections of stepped constructions, wherein upper section and middle section arc transition, middle section is contacted with rubber seal.The utility model bearing effectively improves the problem of the bad pressure maintaining shakiness of existing bearing seal, and it is excellent to realize cylinder roller bearing pressure maintaining sealing performance.
Description
Technical field
The utility model relates to cylinder roller bearing technical field, specifically a kind of combined type pressure stabilizing seals bearing.
Background technique
The high-end milling equipment sealing bearing of field of steel metallurgy proposes more the pressure maintaining ability and dust-proof effect of sealing element
High request, the superiority and inferiority of sealing performance directly affect bearing even milling train operation stability.For a long time, domestic sealing applications effect
Undesirable always, the problems such as bad, easily-deformable, foreign matter intrusion in sealing contact, pressure instability mainly occur, directly affects bearing
Service performance, lead to domestic metallurgy industry sealing bearing market is imported bearing monopolization always.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of combined type pressure stabilizing sealing bearing, it is mainly used in steel
There is the close tolerance seal bearing arrangement of pressure requirements in iron metallurgy rolling mill equipment, as sealing and dust-proof two kinds effects.
For achieving the above object, the utility model uses following technical scheme:
A kind of combined type pressure stabilizing seals bearing, the bearing include outer ring, rolling element, Spring Card collar, rubber seal,
Dust seal cover, sealing inner ring；Rubber seal uses axially and radially three-layer sealed structure, including radial seal lip, axial direction
Sealing lip, inside additional seal lip；Dust seal cover upper end is the dust-proof flange of outer diameter, and dust seal cover internal diameter is three sections of stageds
Structure, dust seal cover outer end face are three sections of stepped constructions, and dust seal cover inner face is three sections of stepped constructions, wherein on
Section and middle section arc transition, middle section is contacted with rubber seal.
Compared with prior art, the utility model has the following beneficial effects: bearing of the present invention to effectively improve existing bearing close
The problem for sealing bad pressure maintaining shakiness, it is excellent to realize cylinder roller bearing pressure maintaining sealing performance.
Detailed description of the invention
Fig. 1 the utility model structure diagram；
Fig. 2 the utility model rubber seal structural schematic diagram；
Fig. 3 the utility model dust seal cover structural schematic diagram.
Specific embodiment
A kind of combined type pressure stabilizing sealing bearing, the bearing includes outer ring 1, rolling element 2, Spring Card collar 3, rubber seal
Circle 4, dust seal cover 5, sealing inner ring 6；Rubber seal 4 uses axially and radially three-layer sealed structure, including radial seal
Lip 41, axial seal lip 42, inside additional seal lip 43, lubricant leakage when preventing axial float and rotating, pressure maintaining sealing effect
Fruit is good；5 upper end of dust seal cover is the dust-proof flange 51 of outer diameter, and 5 internal diameter of dust seal cover is three sections of stepped constructions 54, plays axis
To with circumferential registration, root strengthen and rebound effect；5 outer end face of dust seal cover is three sections of stepped constructions 52, is effectively prevent
Thin-wall part deformation, 5 inner face of dust seal cover are three sections of stepped constructions 53, wherein upper section and middle section arc transition, middle section with
Rubber seal 4 contacts, and is conducive to lubricant reflux and rubber seal protection.
