State rotating shaft and cooperatively form closing space, in closing space internal memory removal of lubricant.
Further, the dead slot is the annular groove formed around the inner ring axis of the bearing.
Further, the cross section of the dead slot is quadrilateral structure or semicircular structure.
Further, the bearing is with lacunose oiliness bearing.
Further, include in the inner ring side of bearing by upper and lower spaced apart two dead slots.
Further, radial direction of the dead slot along bearing inner race is set.
Further, the upper end of the coiling group has the baffle ring extended to central axis direction, has among the baffle ring and allows
The through hole that rotating shaft passes through..
The beneficial effects of the utility model are：
The technical solution of the utility model, the inner ring side of bearing is provided with dead slot, formed between the dead slot and rotating shaft
Closing space, the closing space internal memory removal of lubricant, can be to bearing and the contact portion of rotating shaft when the fan uses
It is lubricated, reduces mechanical wear, improves the service life of fan.

Embodiment
The technical scheme in the embodiment of the utility model is clearly and completely retouched below in conjunction with accompanying drawing 1 to accompanying drawing 2
State, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.It is based on
Embodiment in the utility model, those of ordinary skill in the art are obtained all under the premise of creative work is not made
Other embodiment, belong to the scope of the utility model protection.
If it is to be appreciated that related in the utility model embodiment directionality instruction (such as upper and lower, left and right, it is preceding,
Afterwards ...), then directionality instruction be only used for explain it is relative between each part under a certain particular pose (as shown in drawings)
Position relationship, motion conditions etc., if the particular pose changes, directionality instruction also correspondingly changes therewith.
A kind of bearing oil storage type fan, including a fan frame 10, a stator component 20 and a rotor component 30；The fan frame
10 have a centrally located middle pipe 101, and bearing 40 is set in the middle pipe 101；The stator component 20 has coiling group
201, the coiling group 201 is fixed on the lateral surface of the middle pipe 101；The rotor component 30 has flabellum 301 and is arranged on this
The rotating shaft 302 of the center of flabellum 301；Wherein, the rotating shaft 302 rotates the inner chamber for being socketed in the bearing 40；The bearing
40 inner ring has the dead slot 401 to be caved inward by its medial surface, and the dead slot 401 cooperatively forms closing sky with the rotating shaft 302
Between, in closing space internal memory removal of lubricant.
Specifically, when rotating shaft 302 rotates, will be lubricated between rotating shaft 302 and bearing 40 by lubricating oil, than
Traditional lubricating system, the lubricant effect of the technical program is more preferable, and usage time is longer.It can be good at reducing mechanical friction,
So that rotation is more smoothly, noise is small.
In certain embodiments, the dead slot 401 is the annular groove formed around the inner ring axis of the bearing 40.The party
Case ensure lubricating oil can 360 ° and bearing touch, realize preferably lubrication.Certainly, in addition, the dead slot 401 can be accounted for only
With a region of the inner ring of bearing 40, circumferential run through can't be produced；Only need to set at least one on the inner ring of bearing 40
The individual groove to cave inward can form the dead slot 401.The position that certain dead slot 401 is set must assure that the energy of dead slot 401
Enough and rotating shaft 302 cooperatively forms closing space.
Preferably, it is quadrilateral structure or semicircular structure in the cross section of dead slot described in the present embodiment 401.When being arranged to
The quadrangle is preferably rectangle or square during quadrilateral structure.Specifically, radial direction of the dead slot 401 along the inner ring of bearing 40
Direction is set, and can be easy to process.
In certain embodiments, the bearing 40 is with lacunose oiliness bearing.Coordinate the dead slot 401 and lubrication
Oil, lubricity can be more improved, ensure the service life of fan.
Use, include in the inner ring side of bearing 40 by spaced apart two up and down in order to adapt to various sizes of bearing
Dead slot 401.The technology can ensure to carry out good lubrication to the different zones of bearing.Of course, it is possible to according to different requirements
Design more dead slots 401, for example, three, four it is even more more
When work, the rotating shaft 302 rotates, the inner ring of bearing 40 also concomitant rotation.In the process entirely rotated, profit
Lubricating oil can flow along the gap between bearing 40 and rotating shaft 302, so that the contact portion of whole rotating shaft 302 and bearing 40, leads to
Cross this technique improves greasy property, improve the service life of fan.Certainly, during 40 oiliness bearings of bearing, lubricating oil is also
Can be along the interstitial flow of oiliness bearing, to reach more excellent lubricant effect.
In addition, in order to prevent exogenous impurity from entering fan internal damage rotating shaft.The upper end of the coiling group 201 have to
The baffle ring 2011 of central axis direction extension, have among the baffle ring 2011 and allow the through hole that rotating shaft 302 passes through.The baffle ring 2011 can be with
Stop that exogenous impurity enters.
By the technical solution of the utility model, more preferable lubrication is realized, reduces mechanical wear, improves wind
The service life of fan.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned realities
The mode of applying is changed and changed.Therefore, the utility model is not limited to embodiment disclosed and described above, right
Some modifications and changes of the present utility model should also be as falling into scope of the claims of the present utility model.In addition, to the greatest extent
Some specific terms have been used in pipe this specification, but these terms are merely for convenience of description, not to the utility model
Form any restrictions.
