Abstract
The utility model provides an oil leakage proof structure, which comprises a hydraulic bearing, a rotor spindle arranged on the hydraulic bearing, and fan stators arranged at two sides of the hydraulic bearing, the outside of the fan stators being provided with an oil-proof insulating frame. The oil leakage proof structure is characterized in that the oil-proof insulating frame is provided with a first retaining wall, a second retaining wall and a fourth retaining wall. The outside of the rotor spindle is provided with a fan which comprises a base and a fan blade on the base. The inside of the base is provided with a third retaining wall. The oil leakage proof structure provides the retaining walls for the fan, thus the rotor of the fan when running in high speed can effectively prevent the loss of the lubricating oil in the hydraulic bearing; and the fan rotor and the stator insulating frame have a dust-proof structure, thus improving the useful life of the fan and reducing the fan noise.
Description
Technical field
The utility model relates to the radiation fan technical field, particularly a kind of leak-proof arrangement of fan.
Background technique
In the prior art, at the grease proofing dustproof construction of having of DC fan hydraulic structure, DC fan hydraulic structure energy widespread usage is because contain the soaking by lubricating oil of certain percentage (about 20%) in the fluid bearing to the advantage of the agent structure of radiation fan the inside, when fan propeller connects coaxial core in the running of fluid bearing the inside, because action of centrifugal force can bring out the lubricated effect of playing to the soaking by lubricating oil of fluid bearing the inside, thereby can reach the effect that reduces fan noise and life-saving.Industry is utilized this advantage of fluid bearing, adopts fluid bearing to be applied on the DC fan in a large number.And also this advantage is brought into play to best for this advantage that makes full use of fluid bearing, that lubricant oil that will guarantee the fluid bearing the inside when fan running does not run off, and guarantees that the dust of Environmental Conditions the inside can not enter in the fluid bearing.And general way only has the oily dustproof construction of guarantor in the prior art in the flabellum the inside of fan, when rotor turns round its core can fluid bearing the inside contain immersion oil and make-up oil is taken out of, thereby the bad phenomenon such as lubricant oil minimizing that occur getting rid of between oil and rotor shaft core and fluid bearing produce, so can not bring into play the advantage of fluid bearing fully.
The model utility content
The utility model provides a kind of leak-proof arrangement, makes the rotor of fan prevent the lubricant oil loss of fluid bearing the inside effectively and play the dust-tight effect when running up.
To achieve these goals, the utility model provides following technological scheme:
A kind of leak-proof arrangement, comprise fluid bearing, be installed in rotor shaft core on the described fluid bearing, be installed in the fan stator of described fluid bearing both sides, the outside of described fan stator is equiped with grease proofing insulating frame, wherein, described grease proofing insulating frame is provided with first barricade, second barricade and the 4th barricade.
Wherein, preferred, the described rotor shaft core outside is equiped with fan, and described fan comprises pedestal and the flabellum that is installed on the described pedestal, and described pedestal inboard is provided with the 3rd barricade.
Wherein, preferred, described fluid bearing outer wall has out oil groove.
Wherein, preferred, described oil groove is eight road oil grooves.
Wherein, preferred, described first barricade is towards described rotor shaft core, and perpendicular to described rotor shaft core, described second barricade is perpendicular to described first barricade, and described the 4th barricade is parallel to described second barricade, and described the 3rd barricade inserts between described two barricades and described the 4th barricade.
By implementing above technological scheme, have following technique effect: the utility model provides leak-proof arrangement on the structure of fan barricade to be set, make the rotor of fan prevent effectively that when running up the lubricant oil of fluid bearing the inside runs off, and on the rotor of fan and stator insulating frame, do dustproof construction, to reach the purpose that improves fan life and reduce fan noise.

Embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of leak-proof arrangement, as depicted in figs. 1 and 2, this leak-proof arrangement is applied on the DC fan, this DC fan comprises: fluid bearing 106, be installed in rotor shaft core 107 on the described fluid bearing 106, be installed in the fan stator 108 of described fluid bearing 106 both sides, the outside of described fan stator 108 is equiped with grease proofing insulating frame 103, and described grease proofing insulating frame 103 is provided with first barricade 114, second barricade 113 and the 4th barricade 111.Fluid bearing 106 outer walls have out eight road oil grooves 116.Described first barricade 114 is towards described rotor shaft core 107, and perpendicular to described rotor shaft core 107, described second barricade 113 is perpendicular to described first barricade 114, described the 4th barricade 111 is parallel to described second barricade 113, and described the 3rd barricade inserts between described two barricades 113 and described the 4th barricade 111.Wherein, the A among Fig. 1 is the flow trace line of oil when fan running, and B is that dust enters trajectory.
Wherein, further among the embodiment, described rotor shaft core 107 outsides are equiped with fan, and described fan comprises pedestal 115 and the flabellum 101 that is installed on the described pedestal 115, and described pedestal 115 inboards are provided with the 3rd barricade 112.Described flabellum 101 arranged outside have the fan frame 105 of protection flabellum 101.Described pedestal madial wall is provided with rotor magnet frame 104, and described rotor magnet frame 104 inboards are provided with rotor magnetite 102.
When electric fan 101 runs up; fluid bearing 106 (as shown in Figure 3 and Figure 4; these fluid bearing 106 outer walls have drives eight road oil grooves 116) lubricant oil of the inside because action of centrifugal force can be along rotor shaft core 107 toward fan base 115 upper ends with irregular Radial Flow; after most liquid runs into stopping of first barricade 114; because liquid deadweight and liquid are subjected to the obstacle principle that can reflux; make lubricant oil be back to the accumulator of fan frame 105 again along the oil-return groove 116 on the fluid bearing 106; another little part is escaped from the lubricant oil that is used for grease proofing first barricade, 114 places and can be run into and be used for refluxing after the stopping of the second grease proofing barricade 113 again; because it is total everywhere to be used for grease proofing barricade; four layers of protection so just can reach the loop that the lubricant oil that makes fluid bearing 106 the insides does not run off and can form lubrication oil circulation.
After rotor 101 is turning round a period of time, thereby, athletic meeting strengthens internal pressure because producing a large amount of heats, when internal pressure is excessive, add centrifugal action, lubricant oil can flow out fluid bearing 106 like a cork, this grease proofing structure leaves sufficient space and discharges for internal pressure between fluid bearing 106 and grease proofing insulating frame 103, flow out chance thereby reduce lubricant oil greatly, really play grease proofing and the life-saving effect.
The dust-tight structure is utilized the advantage of plastic rubber shaping; direct dust ring of Front-end Design at rotor; design the 4th barricade 114, second barricade 113 and first barricade 111 as the 3rd barricade 112 with on grease proofing insulating frame 103; when fan running, can stop the dust of environment the inside to enter into fluid bearing 106 the insides effectively; protect fluid bearing effectively, the life-span of whole fan is improved.
More than a kind of leak-proof arrangement that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
