Abstract
The invention discloses a bearing seal device. The bearing seal device comprises a bearing outer ring, a bearing inner ring, a rolling ball and dustproof covers, wherein the dustproof covers are arranged between the bearing outer ring and the bearing inner ring, and comprise support bodies and dustproof elements; one contact ends of the dustproof elements and the bearing inner ring comprise first branches and second branches; the first branches are in horizontal fit with the bearing inner ring; the second branches are in longitudinal fit with the bearing inner ring. Compared with the prior art, according to the invention, because the seal device can be in radial contact with the bearing inner ring, and also can be in axial contact with the bearing inner ring, external impurities, moisture and the like have difficulty in entering the bearing, the seal effect is good, the precision and using performances of the bearing are increased, and the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to a kind of sealing device, especially relate to a kind of associated sealing arrangement for bearings.
Background technology
Bearing is for determining rotary shaft and other parts relative motion position, playing the parts of supporting or guide effect.
The major function of bearing is supporting rotating shaft or other movable body, guiding rotation or moving movement and bears by axle or parts on shaft
The load being transmitted to.
Bearing is to start to step into the arena of history with the appearance of human industry's civilization.In 16th century, west starts to rise
The industrial revolution, to 18th century mid-term, bearing starts as independent mechanical organ to occur.To earlier 1900s, bearing
Technology enters modern development period, has initially formed bearing industry in large scale.Enter 21st century, bearing has been to work as
For indispensable base parts and components in plant equipment, apply quite varied in national economy every profession and trade, its precision, performance,
Life and reliability plays conclusive effect to the precision of main frame, performance, life and reliability.
Existing bearing is mainly made up of inner ring, outer ring, lasso, steel ball, steel ball retainer, sealing device.Inner ring, outer ring
Effect is: rotation, support, transmitting torque；The effect of lasso is: is assemblied in the hole；The effect of steel ball is: bears load；Steel ball
Retainer role is: steel ball is separated；The effect of sealing device is；Sealing, prevents grease leakage and introduced contaminants, moisture
Enter bearing.The sealing device of current bearing is generally radially contacted with bearing inner race, and sealing property is bad, introduced contaminants, water
Grade and be easily accessible Bearing inner, have impact on precision and the performance of bearing, and then result in the service life of bearing and reduce.
Content of the invention
The present invention is directed to deficiency of the prior art, there is provided a kind of associated sealing arrangement for bearings, can either be with bearing inner race footpath
To laminating, axially can fit with bearing inner race, introduced contaminants, moisture etc. hardly enter Bearing inner, good sealing effect again.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of associated sealing arrangement for bearings,
Including bearing outer ring, bearing inner race, ball and dust cap, described dust cap be arranged on bearing outer ring and bearing inner race it
Between, described dust cap includes supporter and dust guard, and one end that described dust guard is contacted with described bearing inner race includes
First branch and the second branch, the first described branch and described bearing inner race transverse fit, the second described branch and institute
The bearing inner race stated longitudinally is fitted.Such setting, the good sealing effect of bearing, introduced contaminants, moisture etc. hardly enter bearing
Internal.
In order to obtain superior technique effect, further technological improvement also includes, and described dust guard is provided with second
Groove, described supporter is elastomer, and the length of described supporter is more than the length of the second described groove, and described
Supporter be snapped in the second described groove.Such setting is so that dust guard is obtaining powerful support, so that bearing
Sealing effectiveness more preferable.
In order to obtain superior technique effect, further technological improvement also includes, the first described branch and described
The crosspoint of the second branch is located at the top of described supporter point midway.Such setting is so that the Liang Ge branch of dust guard
Distribution of force evenly, thus ensureing sealing effectiveness.
In order to obtain superior technique effect, further technological improvement also includes, the first described branch and described
Angular range between second branch is 45 °～90 °.
In order to obtain superior technique effect, further technological improvement also includes, and the cross section of described supporter is in
" l " shape.Such setting, what supporter was strong supports dust guard.
In order to obtain superior technique effect, further technological improvement also includes, described dust guard and bearing outer ring
One end of contact is provided with " u " shape structure.
In order to obtain superior technique effect, further technological improvement also includes, and described bearing outer ring is provided with
One groove, the first described groove is provided with annular slab, and described dust guard is snapped in the first groove by " u " shape structure
Interior.Such setting so that dust guard be combined with bearing outer ring more firm.
The invention has the beneficial effects as follows: because this sealing device radially can either be fitted with bearing inner race, again can be with axle
Hold inner ring axially to fit, introduced contaminants, moisture etc. hardly enter Bearing inner, sealing effectiveness more preferably, increased the precision of bearing
And serviceability, extend the service life of bearing.
Brief description
Fig. 1 is the overall schematic of bearing of the present invention.
Fig. 2 is the partial schematic diagram of the present invention.
Specific embodiment
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to shown in Fig. 1 and Fig. 2, a kind of specific embodiment of associated sealing arrangement for bearings of the present invention: a kind of associated sealing arrangement for bearings,
Including bearing outer ring 1, bearing inner race 2, ball 3, dust cap 4 and bearing cage 5, described dust cap 4 is arranged on described
Bearing outer ring 1 and described bearing inner race 2 between, described dust cap 4 includes supporter 41 and dust guard 42, and described is anti-
One end that dirt part 42 is contacted with described bearing inner race 2 includes the first branch 44 and the second branch 45, described the first branch 44
With described bearing inner race 2 transverse fit, described the second branch 45 is longitudinally fitted with described bearing inner race 2, such sets
Put, the good sealing effect of bearing, introduced contaminants, moisture etc. hardly enter Bearing inner.Described dust guard 42 is provided with second
Groove 43, described supporter 41 is elastomer, and the length of described supporter 41 is more than the length of the second described groove 43,
And described supporter 41 is snapped in the second described groove 43, such setting is so that dust guard is effectively being propped up
Support, so that the sealing effectiveness of bearing is more preferable.The crosspoint 46 of the first described branch 44 and the second described branch 45 is located at
The top of described supporter 41 point midway, such setting so that the Liang Ge branch distribution of force of dust guard evenly, thus
Ensure sealing effectiveness.Angular range between the first described branch 44 and the second described branch 45 is 45 °～90 °.Described
Supporter 41 cross section be in " l " shape, such setting, what supporter was strong supports dust guard.Described dust guard 42
