The utility model provides a radiator fan of leak protection oil forms a cavity between oil-retaining bearing and the insulating cover, reduces the direct straight wall outflow of lubricating oil and the loss, causes the product inefficacy, the effectual life-span that improves the product.
Description
Technical Field
The utility model relates to a fan specifically is a radiator fan of leak protection oil.
Background
As shown in fig. 1 to 3, the conventional heat dissipation fan is lubricated by the oil and the external oil of the oil-retaining bearing body between the shaft core 7 and the oil-retaining bearing 9, but the fan generates centrifugal force during high-speed operation, and the lubricating oil acting between the oil-retaining bearing 9 and the shaft core 7 flows to the bottom of the fan blade under the action of the centrifugal force and is thrown out from the top; although the lower end of the fan is sealed by the oil cover 10, the leakage of lubricating oil cannot be completely avoided, so that the lubricating oil between the oil-containing bearing and the shaft core can be gradually lost, the fan which is lack of effective lubrication can have the defects of vibration, noise increase, change of rotating speed and the like, and the service life can be greatly shortened. Therefore, how to solve the above problems is a problem to be solved urgently.
Disclosure of Invention
The utility model discloses to above technical problem, provide a radiator fan of leak protection oil, form a cavity between oil-retaining bearing and the insulating cover, reduce lubricating oil and directly flow in the same direction as straight wall and the loss, cause the product to become invalid, the effectual life-span that improves the product.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a kind of heat-dissipating fan of oil leakage prevention, including the outer gimbal, the outer gimbal has centre posts with recess, there are oil-retaining bearings in the recess, the oil-retaining bearing is equipped with the axle core of the fixed flabellum, the wear-resisting plate between bottom of recess and the axle core, the axle core exposes the end of oil-retaining bearing and is equipped with the packing ring, retaining ring; the stator is fixed on the circumference of the outer frame center column, an insulating cover is arranged outside the stator and extends to the end face of the oil-containing bearing, and a cavity is formed between the oil-containing bearing and the external connecting part and between the oil-containing bearing and the insulating cover.
Further, the inner surface and the outer surface of the middle part of the oil-retaining bearing are respectively provided with a groove. An oil storage cavity is formed between the inner surface groove and the shaft core, and another oil storage cavity is formed between the outer surface groove and the inner surface of the central column, and the two oil storage cavities store lubricating oil to ensure the lubrication between the shaft core and the bearing.
Compared with the prior art, the utility model have following technical advantage:
1. the oil-containing bearing of the cooling fan is positioned in the groove of the outer frame central column, and the inside of the groove is of a sealing structure, so that the oil-containing bearing in the groove is effectively ensured not to leak oil;
2. the oil-retaining bearing is connected with the external connecting part, and a cavity is formed between the oil-retaining bearing and the insulating cover, so that the loss of lubricating oil caused by direct outflow along the straight wall is reduced, the product failure is caused, the service life of the product is effectively prolonged, and experimental data show that the service life of the cooling fan can be prolonged by 5%.

Detailed Description
The invention will be described in further detail below with reference to embodiments shown in the drawings.
As shown in fig. 4 to 6, the oil leakage preventing heat dissipating fan of the present invention comprises an outer frame 1, wherein the outer frame 1 is provided with a central column 2 with a groove, an oil bearing 9 is arranged in the groove, a shaft core 7 for fixing a fan blade 6 is arranged in the oil bearing 9, a wear-resistant plate 3 is arranged between the shaft core 7 and the bottom of the groove, and a washer 5 and a retaining ring 4 are arranged at one end of the shaft core 7 exposed out of the oil bearing 9; the stator 11 is fixed on the circumference of the outer frame central column 2, an insulating cover 10 is arranged outside the stator 11, the insulating cover 10 extends to the end face of the oil-containing bearing 9, and a cavity 8 is formed between the oil-containing bearing 9 and an external connecting part and between the oil-containing bearing 9 and the insulating cover 10.
As shown in fig. 4, the inner surface and the outer surface of the center portion of the oil-impregnated bearing 9 are provided with grooves, respectively.
As shown in fig. 5/6, a cavity 8 is formed between the oil-retaining bearing 9 and the insulating cover 10, so that the loss of lubricating oil caused by directly flowing out along the straight wall is reduced, and the product is failed.
To sum up, the present invention, as described in the specification and the drawings, is made into a practical sample and tested by multiple use, and from the test result, it is proved that the utility model can achieve the intended purpose, and the practicability is undoubted.
