Description
Technical field
The utility model belongs to the mixing plant arrived involved in lithium battery processing technology industry, refers in particular in mixing plant
Dispersion axis seal protecting device.
Background technology
Blender in the market in lithium battery leading portion dispersion process, is sealed with equipment very high requirement, prevents bearing
On oil be leaked to slurry, scrap slurry；It is also prevented from stirring slurry simultaneously to penetrate on bearing, damages bearing.It generally adopts at present
With outside framework oil seal or dispersion sealing, although outside framework oil seal and dispersion sealing are close good, there is no oil leaks etc. in the short time
Phenomenon, but in axis high speed rotation is disperseed, outside framework oil seal can generate high temperataure phenomena with dispersion axis high-speed friction（Higher than 80 DEG C）,
High temperature influences cell size performance（Higher than 80 DEG C positive battery slurries exist into jelly state, damage slurry）, high temperature simultaneously shadow
Ring bearing life（In bearing high temperature, the oil in bearing can volatilize, and oil leakage phenomenon is apparent, and the few oil of bearing does not have oil, influences the service life）, together
Shi Gaowen can make slurry absorption influence equipment cleaning and cost on dispersion axis and dispersion axle bed.Once for a long time, due to oil sealing material
Matter has the characteristics that very strong heat resistant and wear resistant, matching therewith and the corresponding position of dispersion axis can be ground rough existing
As dispersion axis is made not have sealing performance.Whole is also resulted in simultaneously disperses scrapping for axis.It is done by long-term two contact surfaces
During pure rolling friction, under the action of height contacts tension and compression stress, after excessive power cycle, the decrease of fatigue strength of axis is caused, very
It swings or is broken to will appear, seriously affect the function of motion.
Invention content
The technical problem to be solved by the present invention is to provide a kind of seal protecting device for disperseing axis, good airproof performance, drops
The heat generated during low dispersion axis high speed rotation, avoids axle temperature excessively high.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of seal protecting device for disperseing axis, the dispersion axis including bearing block and across the bearing block, dispersion axis pass through
Bearing and bearing block attaching, the top and bottom of bearing block are respectively equipped with top bearing cover and lower bearing end cap, disperse on axis to cover
Equipped with getting rid of, material is bad, has gap, the madial wall of lower bearing end cap between the madial wall of the lower bearing end cap and dispersion axis outer wall
Equipped with outside framework oil seal, disperse fixing sleeve on axis and contacted equipped with wear ring, the wear ring with outside framework oil seal fitting.
Fixing sleeve is equipped with stainless steel sleeve on the dispersion axis, which is equipped with screens, and wear ring fixing card is mounted in
In the screens of the stainless steel sleeve.
Fluid sealant is coated between the stainless steel sleeve and dispersion axis.
The wear ring is made of zirconium oxide or silicon nitride material.
The stainless steel sleeve lower inner wall is equipped with sealing ring.
It is interference fit between the wear ring and stainless steel sleeve.
Sealing strip is equipped between the lower bearing end cap and bearing block.
Bearing between the dispersion axis and bearing block is deep groove ball bearing.
The utility model is contacted by wear ring with outside framework oil seal, and wear ring follows dispersion axis to rotate together so that wear-resisting
Because the heat that friction generates is not easy all to be transmitted on dispersion axis between ring and outside framework oil seal, avoid axle temperature excessively high, reduce bearing
Temperature.Abrasion of the outside framework oil seal to dispersion axis surface is also avoided simultaneously, is extended the service life of dispersion axis, is improved leakproofness
Energy.
Description of the drawings
Attached drawing 1 is the utility model part section structural representation；
Attached drawing 2 is the utility model wear ring and the cross-sectional view after stainless steel sleeve assembling.
Specific embodiment
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific embodiment with reference to attached drawing.
As shown in figure 1 and 2, the utility model discloses a kind of seal protecting device for disperseing axis, including 1 He of bearing block
Across the dispersion axis 4 of the bearing block 1, dispersion axis 4 is by deep groove ball bearing 8 and 1 attaching of bearing block, and the upper end of bearing block 1 is under
End is respectively equipped with top bearing cover and lower bearing end cap 7, disperses on axis 4 to be set with and gets rid of material bad 5, the lower bearing end cap 7 it is interior
There is gap, the madial wall of lower bearing end cap 7 is equipped with outside framework oil seal 8, disperses fixed on axis 4 between side wall and dispersion 4 outer wall of axis
Wear ring 2 is set with, which contacts with the fitting of outside framework oil seal 8.Lower bearing end cap and top bearing cover pass through bolt and axis
Bearing locking assembling.Wear ring is made of zirconium oxide or silicon nitride material, has higher thermal insulation and wearability, it is ensured that it makes
Use the service life.
In addition, for fixing sleeve equipped with stainless steel sleeve 3, which is equipped with screens on the dispersion axis 4, wear ring 2 is solid
Surely it is installed in the screens of the stainless steel sleeve 3.Fluid sealant is coated between stainless steel sleeve and dispersion axis.Wear ring and stainless steel sleeve
Between for interference fit, it is ensured that the wear-resisting firm installation with stainless steel sleeve.
3 lower inner wall of stainless steel sleeve is equipped with sealing ring 6, further improves sealing performance.
Sealing strip is equipped between the lower bearing end cap 7 and bearing block.
Bearing between the dispersion axis and bearing block is deep groove ball bearing.
In the utility model, using the stainless steel sleeve being fixedly set on dispersion axis, wear ring is assembled on stainless steel sleeve,
The stainless steel sleeve and wear ring follow dispersion axis to rotate together, and wear ring contacts friction with outside framework oil seal.By traditional dispersion axis
The structure that friction is in direct contact with outside framework oil seal is improved to the structure that wear ring contacts with outside framework oil seal friction, avoids dispersion axis
With being in direct contact for outside framework oil seal, and between wear ring and outside framework oil seal because friction generate heat can by wear ring obstruct one
Determine heat, the temperature for avoiding dispersion axis is excessively high, so as to reduce the temperature of bearing, extends the service life of the decomposition axis of bearing.And
And will not be in direct contact due to decomposing axis with outside framework oil seal, avoid outside framework oil seal abrasion caused by dispersion axis.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement is carried out to which part technical characteristic,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
