Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
A kind of fan as shown in figs. 1-7, including shell 10 and the bearing 20 being arranged in shell 10 and be sheathed on
Central spindle 30 on bearing 20 is formed with the first gap 201,20 periphery of bearing and 10 inner wall of shell between central spindle 30 and bearing 20
Between be formed with the second gap 301,20 upper surface of bearing and 10 inner top surface of shell are with merging the first shoe cream room 101 of formation, and the
One gap 201 is connected to by the first shoe cream room 101 with the second gap 301, is suitable for the lubricating oil in the first gap 201 and is passed through the
One shoe cream room 101 flows into the second gap 301, and is suitable for lubricating oil in the first shoe cream room 101 and flows back in the second gap 301, shell
The bulge loop 121 for being formed with and abutting with 20 lower end surface of bearing is provided in body 10,121 lower end surface of bulge loop and 10 inner bottom surface of shell cooperate
And the second shoe cream room 102 is formed, the company for being connected to second gap 301 and second shoe cream room 102 is offered on bulge loop 121
Interface 1213, the second gap 301 are connected to the first gap 201 by the second shoe cream room 102, are suitable in the second gap 301
Lubricating oil is flowed into the first gap 201 by the second shoe cream room 102.
When the application fan work, central spindle 30 is by high-speed rotation, and central spindle 30 will rub with bearing 20 when rotation, so that
Temperature in shell 10 increases, and the lubricating oil in the first gap 201 is heated to be expanded, and along 30 inner wall of central spindle upwards to excessive
Out, and under the influence of centrifugal force it entering in the first shoe cream room 101, lubricating oil will recycle in the first shoe cream room 101,
Parts of lubricating oil will be flowed under gravity in the second gap 301 simultaneously, and flow into the second oil storage by the second gap 301
In chamber 102, the lubricating oil of the second shoe cream room 102 will be attached to 30 surface of central spindle under the action of its tension, and in the work of temperature
It is moved upwards under with central spindle 30, realizes the circulation of lubricating oil, when central spindle 30 effectively being avoided to run at high speed, lubricating oil is in centrifugal force
And the first gap 201 is left under the action of heating power, the lubrication of lubricating oil is lacked between central spindle 30 and bearing 20 and is occurred acutely
Friction, causes temperature in shell 10 to steeply rise, and fan is excessively high impaired because of temperature.
Specifically, 20 surface of bearing offers oil groove 21, in order to which lubricating oil enters in the second gap 301, realizes lubrication
The circulation of oil.
More specifically, 121 lower end surface of bulge loop, which offers V-groove 1211, is partially attached to central spindle when central spindle 30 runs at high speed
The lubricating oil on 30 surfaces will be entered under the influence of centrifugal force in the second shoe cream room 102, since 102 space of the second shoe cream room has
Limit, the lubricating oil for being dumped into the second shoe cream room 102 will hinder the lubrication flowed into the second shoe cream room 102 through the second gap 301
Oil stream goes out, and influences outflow of lubrication oil efficiency in the second shoe cream room 102, therefore offers V-groove 1211 in 121 lower end surface of bulge loop, makes
The lubricating oil of the second shoe cream room 102 and the lubricating oil generation pair flowed into the second shoe cream room 102 through the second gap 301 must be dumped into
Stream.
In addition, the lubricating oil being partially stored in the first shoe cream room 101 will be in the work of its tension when central spindle 30 runs at high speed
It is brought under in central spindle 30, in the process, the lubricating oil for hindering central spindle 30 to throw away is flowed into the first oil storage by above-mentioned lubricating oil
In chamber 101, the inflow efficiency of lubricating oil is reduced, and is the generation for avoiding above situation, it is recessed one can be opened up in 10 inner top surface of shell
Slot, so that convection current occurs for the lubricating oil for flowing out the first shoe cream room 101 and the lubricating oil for flowing into the first shoe cream room 101.
Specifically, 20 lower end surface of bearing and 121 upper surface of bulge loop be with merging to form third space, and the first gap 201 with
And second gap 301 be connected to third space, be suitable in the second gap 301 lubricating oil and pass through third space flowing into the first gap
In 201, so that lubricating oil is replenished in time into central spindle 30.
More specifically, 121 upper surface of bulge loop is provided with chamfering 1212, it is suitable for lubricating oil in third space and flows between first
In gap 201.
Specifically, fan further includes fixed frame 4, flabellum 5, the magnet ring 6 for being installed on 5 bottom end of flabellum and is arranged in magnet ring 6
Interior magnetic floats column 7, and shell 10 is installed on fixed frame 4, and the setting of shell 10 is floated in column 7 and affixed, the bearing that floats column 7 with magnetic in magnetic
20 tops are connect with flabellum 5, in order to which bearing 20 drives flabellum 5 to be rotated.
Shell 10 includes pipe 12 in outline border, is installed on the stator 13 on 12 top of pipe in outline border and is installed on pipe 12 in outline border
The rear cover 14 of bottom end, bearing 20 are arranged in outline border in pipe 12, and 13 lower end surface of stator and 20 upper surface of bearing form the with merging
One shoe cream room 101,14 upper surface of rear cover, which matches to merge with 121 lower end surface of bulge loop, forms the second shoe cream room 102, so that shape in shell 10
At enclosure space, effectively lubricating oil is avoided to overflow.
More specifically, snap component is provided in outline border between pipe 12 and stator 13, snap component includes being formed and stator 13
The fixture block of lower end surface and the card slot for being provided with 12 surface of pipe in outline border, when stator 13 is installed on pipe 12 in outline border, fixture block is suitable
In insertion card slot, the stability of structure is improved, while facilitating the maintenance of fan.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
