Abstract
A kind of bearing seal structure, including axle envelope, end cap, sealing bearing, further include sealing gland ring, and the sealing gland ring includes inner ring, outer ring and compression ring, and venthole is provided on the compression ring, and the venthole is connect by air inlet with compressed air.The inner ring, the compression ring, the outer ring are sequentially connected, airtight between each other, and the section of the sealing gland ring is I-shaped.The inner ring, the outer ring inner ring surface do not contacted with axis, interior diameter ratio shaft is slightly larger；The inner ring, the outer ring outer ring surface all contacted with shell, formed outer ring seal face.Enclosure seal bearing is installed in the cover board of installation on one side and axle envelope of the sealing gland ring, another side.The axle envelope is installed between the cover board and axis.The internal diameter of the cover board contacts the cover board with the outer ring between the outer diameter and internal diameter of the outer ring, forms left side sealing surface.The housing side has prominent circle, and the prominent circle is contacted with the outer ring of the sealing bearing, forms right sealing surface.
Description
Technical field
The present invention relates to a kind of bearing seal structures.
Background technique
Currently, requiring to use bearing in transmission, in the use process of bearing, need to bearing lubrication and holding shaft
The cleaning held, especially cannot be by the pollution of powder, grit, liquid.Current seal approach has the most common axle envelope, filler
Letter seals and using the enclosure seal bearing with sealing cover.But packing seal structure is simple, cheap, maintenance side
Just.But leakage rate is big, power consumption penalty is big, and the effect of axle envelope is limited, once axle envelope damage, the substances such as powder can by breakage into
Enter in bearing, influences bearing service life, or even cause production accident.And use sealing bearing to some extra fine powder
End is still difficult to play good effect.
Moreover, the damage of axle envelope is difficult to detect and find, damaged if there is axle envelope, people only in maintenance or
It is that could be found after bearing damage, this can produce and bring big inconvenience.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of bearing seal structure that effect is good and can detect sealing leak
Device.
The technical scheme adopted by the invention is that a kind of bearing seal structure, including axle envelope, end cap, sealing bearing, it is special
Sign is: further including sealing gland ring, the sealing gland ring includes inner ring, outer ring and compression ring, and venthole is provided on the compression ring, described
Venthole is connect by air inlet with compressed air.
The inner ring, the compression ring, the outer ring are sequentially connected, and airtight between each other, the section of the sealing gland ring is
I-shaped.
The inner ring, the outer ring inner ring surface do not contacted with axis, interior diameter ratio shaft is slightly larger；It is the inner ring, described outer
The outer ring surface of ring is all contacted with shell, forms outer ring seal face.
Further, enclosure seal bearing is installed in the cover board of installation on one side and axle envelope of the sealing gland ring, another side.It is described
Axle envelope is installed between the cover board and axis.The internal diameter of the cover board makes described between the outer diameter and internal diameter of the outer ring
Cover board is contacted with the outer ring, forms left side sealing surface.
The housing side has prominent circle, and the prominent circle is contacted with the outer ring of the sealing bearing, forms right sealing surface.
The enclosure seal bearing can be dual face seals, be also possible to single facer, close when being single facer
Cover is contacted with the sealing gland ring.
Further, in order to find that an air horn is also arranged in bearing damage, the present invention on air inlet pipeline in time.
Detailed description of the invention
Fig. 1 is the schematic diagram that ladder of the present invention cuts open.
In figure: 1- inner ring, 2- compression ring, 3- outer ring, 4- cover board, 5- axle envelope, 6- axis, the left sealing surface of 7-, the upper sealing surface of 8-, 9-
The prominent circle of venthole, 10-, 11- air inlet, the right sealing surface of 12-, 13- shell, the bearing seal face 14-, 15- seal bearing.
Specific embodiment
Further illustrate a specific embodiment of the invention with reference to the accompanying drawing.
It further include sealing gland ring as shown in Figure 1, the present invention includes axle envelope, end cap, sealing bearing, sealing gland ring includes inner ring, outer
Ring and compression ring, venthole is provided on compression ring, and venthole is connect by air inlet with compressed air.
Inner ring, compression ring, outer ring are sequentially connected, airtight between each other, and the section of sealing gland ring is I-shaped.
Inner ring, outer ring inner ring surface do not contacted with axis, interior diameter ratio shaft is slightly larger；Inner ring, outer ring outer ring surface all with shell
Body contact, forms outer ring seal face.
Further, enclosure seal bearing is installed in the cover board of installation on one side and axle envelope of sealing gland ring, another side.Axle envelope installation
Between cover board and axis.The internal diameter of cover board contacts cover board with outer ring between the outer diameter and internal diameter of outer ring, and it is close to form left side
Cover.
Housing side has prominent circle, and prominent circle is contacted with the outer ring of sealing bearing, forms right sealing surface.
Enclosure seal bearing can be dual face seals, be also possible to single facer, when being single facer, sealing surface
It is contacted with sealing gland ring.
The course of work of the invention is: compressed air enters at compression ring through air inlet, due to the sealing in outer ring seal face
Effect, gas can only continue downwards, by entering between axis and compression ring after venthole.Gas will continue to through outer ring, inner ring
It spreads to the left and right in gap between axis.To the left, it is prevented to continue to spread by bearing and left sealing surface；To the right, by right sealing surface
It is prevented to continue to spread.At this point, compressed air does not flow.
If the axle envelope in left side is damaged, compressed air can be from the place damaged to outward leakage, and gas of this leakage can incite somebody to action
The substances such as extraneous powder are blown away, and sealing gland ring cannot be entered by the place of damage by, which being allowed to, further pollutes bearing, reaches
Protect the purpose of bearing.Simultaneously as the leakage of compressed air, originally immobilising compressed air can flow, and flow
Compressed air can make the air horn in air inlet pipeline issue the sound, play the effect of prompting.
