Description
Technical field
The present invention relates to a kind of box bearing oil-leakage-prevention rubber seal.
Background technology
There is the equipment manufacturing skill of liquid or gas conveying in large-scale engineering machinery equipment, oil, gas pipeline, transformer etc.
In art field, in order that machine internal cavity sealing effectiveness is more preferable, liquid or gas are prevented to outward leakage, usually in mechanical fitting
Different sealing strip or sealing ring are accompanied between axially being docked with mechanical fitting, can make to reach internal at mechanical rotating parts
Cavity seals, and realizes sealing and the conveying to liquid or gas.
For bearing for essential in plant equipment, bearing seal is bearing in the crucial portion that adverse circumstances run well
Part, it, which is played, protects the bearing from corroding and pollutes, and bearing is kept stable internal work environment, improves stability, extends
Service life.
However, traditional contact rubber seal circle can not ensure bearing in the high speed running apparatus such as motor, gear-box
Prevent extraneous water, oil from entering Bearing inner for a long time；Traditional contact rubber seal circle can only be under 6000 revs/min of rotating speed
Prevent extraneous water, oil intrusion 60 hours.Rubber seal is deformed by process compresses to reach sealing machine device, causes list
The rubber seal internal stress of one material is bigger, and size is difficult to ensure that, easy aging after use, and elasticity is deteriorated after deformation,
Coordinate relaxation, service life shortens.
Chinese patent application (CN206190751U) specification ejects for sealing ring because of HTHP from bearing, shadow
Ring the service life of bearing and disclose a kind of heat-resisting bearing sealed ring, including the skeleton of annular and the rubber for being attached to skeleton
Colloid, described rubber bodies include being connected to the sealed lip at skeleton inner diameter edge and being connected at skeleton radial outer edge
Location division, it is axially extending on the end face on the outside of the direction of skeleton to have multiple radiating thin slices.Traditional contact in the patent application
Formula rubber seal effectively can make sealing ring be radiated, and but can not effectively prevent extraneous water, oil from entering Bearing inner.
The content of the invention
For technical problem present in prior art, the present invention provides a kind of box bearing oil-leakage-prevention rubber seal
Circle.
The present invention prevents bearing external world's water, oil intrusion Bearing inner when running at high speed, and keeps bearing internal condition stable,
Extend bearing service life, solve traditional contact rubber seal circle causes to make because of extraneous water, oil intrusion Bearing inner
The problem of with short life.
A kind of box bearing oil-leakage-prevention rubber seal, including the skeleton of annular and the rubber that is fixedly connected on skeleton
Colloid, described rubber bodies include and bearing outer ring is in the outer ring lip of groove contact seal and groove contacts during with bearing inner race
The annular lip of formula sealing, the rubber bodies also include the protuberance to stretch out along the radial direction of annular lip；Institute
Stating protuberance has with the contact surface of the portion end surface flat seal of bearing inner race and is contacted with the axle surface through bearing inner race
The sealing surface of formula sealing.
Preferably, the angle of described contact surface and the sealing surface is 100 °.
Preferably, the cross section of the annular skeleton is L-type structure.
Preferably, the cross section of described annular lip is class V-structure.
Preferably, the angle of described contact surface and the sealing surface is 95-105 °.
The described and contact surface of the portion end surface flat seal of bearing inner race width is the end face width of bearing inner race
Half.
The present invention provides a kind of built-in circular ring metal skeleton, there is the bearing rubber seal of four oil-leakage-prevention techniques：
(1) sealing ring external diameter utilizes elastic rubber, with the groove contact seal of bearing outer ring side, prevents extraneous water, oil intrusion.
(2) there are three oil-leakage-prevention sealing technologies on the inside of sealing ring.
(1) internal diameter of the seal ring utilizes rubber and bearing inner race V-groove contact seal.
(2) internal diameter of the seal ring carries out contact seal using rubber and bearing inner race portion end surface.
(3) internal diameter of the seal ring is prevented extraneous water, the intrusion of oily direct-axis shelves, is reached preferable using rubber and axle shelves tight seal
Leakproof oil sealing effect.
The present invention superscribes loop configuration rubber on the basis of circular ring metal skeleton.Outside by external diameter rubber and bearing
Enclose V-groove contact seal；Internal diameter rubber and bearing inner race V-groove contact seal；Internal diameter rubber and bearing inner race part end
Face contact type seals；Internal diameter rubber is in close contact with axle shelves and sealed.On the basis of circular ring metal skeleton, increase rubber and axle
Hold, the contact area of axle shelves, lift-off seal circle sealing property, ensure bearing can under high speed conditions the impurity such as extraneous water, oil
Bearing inner is cannot be introduced into, compared with traditional contact rubber seal circle, under same working condition, bearing life can be prolonged
It is long more than one times.Through experiment, box bearing oil-leakage-prevention rubber seal of the invention can prevent under 6600 revs/min of rotating speed
Extraneous water, oil intrusion were up to 150 hours.
Brief description of the drawings
Fig. 1 is the pictorial diagram of the embodiment of the present invention 1.
Fig. 2 is the cross-sectional view cutd open for Fig. 1 A-A.
Fig. 3 is the cross-sectional view of section on the left of Fig. 2.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings
Embodiment 1
As Figure 1-3, a kind of box bearing oil-leakage-prevention rubber seal, including the skeleton 1 of annular and fixed company
The rubber bodies 2 being connected on skeleton, described rubber bodies 2 are included in have at the radial outer edge of skeleton 1 to be contacted with bearing outer ring side groove
The outer ring lip 21 of formula sealing, there is annular lip with the groove contact seal of bearing inner race side at the inner diameter edge of skeleton 1
Portion 22, the rubber bodies also include the protuberance 23 to stretch out along the radial direction of annular lip 22；The protuberance 23
Contact surface 231 with the portion end surface flat seal with bearing inner race and with the axle surface contact sealing through bearing inner race
Sealing surface 232.The angle of described contact surface 231 and the sealing surface 232 is respectively 95 °, 100 °, 105 °.
The cross section of annular skeleton 1 described in the present embodiment is L-type structure, the cross section of described annular lip
For class V-structure.
The box bearing oil-leakage-prevention rubber seal of the present invention water can be immersed up to test knot under 6600 revs/min of rotating speed
Fruit such as table 1：
| Sequence number | Angle | Sealing period |
| 1 | 95° | 130 |
| 2 | 100° | 150 |
| 3 | 105° | 140 |
The box bearing oil-leakage-prevention rubber seal of the present invention oil intrusion can reach test knot under 6600 revs/min of rotating speed
Fruit such as table 2：
| Sequence number | Angle | Sealing period |
| 1 | 95° | 130 |
| 2 | 100° | 150 |
| 3 | 105° | 140 |
Table 2
Thus draw：The box bearing oil-leakage-prevention rubber seal and traditional contact rubber seal circle phase of the present invention
Than for the angle of described contact surface 231 and the sealing surface 232 at 95 ° -105 °, service life is considerably longer than traditional
Contact rubber seal circle, and when contact surface 231 and the angle of sealing surface 232 are 100 °, waterproof, oil intrusion effect reach most
It is good, under 6600 revs/min of running at high speed, bearing service life has been reached 150 hours, be traditional contact rubber seal
Enclose service life 2.5 times.
