Abstract
The invention discloses an LED (light emitting diode) radiating fan with long service life. The LED radiating fan with the long service life comprises an outer frame and blades, wherein the outer frame is provided with a bearing block; the bearing block is provided with a bearing; the blades are arranged on the bearing through a central spindle; an oil-guiding and voltage-buildup groove is formed in the inner wall of the bearing; and two ends of the bearing are sealed by end caps. By using the radiating fan, a phenomenon that the central spindle and the bearing rub with each other to generate heat is effectively avoided, dust is prevented from entering the bearing, oil is prevented from leaking from the bearing, the service life of the fan is greatly prolonged, and the severe environment adaptability of the fan is greatly improved. The LED radiating fan is quite durable, and is suitable for dissipating heat of LED.
Description
Technical field
The present invention relates to blower fan technical field, especially a kind of long-life type LED cooling fan.
Background technique
For cooling fan, its structure must relate to fan shaft core and bearing, existing fan shaft core and bearing contact in the time of relative movement, produce frictional heat energy and friction noise, and dust enters in bearing and oil leakage goes out, between axle core and bearing, produce in the running heat energy and make oil evaporation and loss, thereby have influence on the working life of cooling fan.
Summary of the invention
The object of this invention is to provide one and avoided axle core and the mutual frictional heat of bearing, prevent that dust from entering bearing and oil leakage goes out, the long-life type LED cooling fan that the life-span is long.
For achieving the above object, the technical solution adopted in the present invention is: a kind of durable type LED cooling fan, comprise housing, flabellum, on housing, be provided with bearing support, bearing is installed on bearing support, flabellum is arranged on bearing by axle core, is provided with Oil Guide builds pressure groove at the inwall of bearing, passes through end bracket enclosed at the two ends of bearing.
Preferably, described Oil Guide build press groove be man type groove.
Preferably, described Oil Guide is built the two ends up and down of pressing groove to be positioned at bearing inner wall.
Preferably, the internal diameter of described bearing intermediate section is greater than and Oil Guide is set builds and press the internal diameter of groove position, has effectively avoided contacting of bearing and axle core while pressing building.。
The present invention adopts after said structure, build pressure groove by Oil Guide being set at the inwall of bearing, and by end cap sealed at both ends by bearing, between axle core and bearing, produce so a kind of oil film pressure when fan running, pressure is built in generation, axle core and bearing are kept apart completely, do not contact, thereby make it not produce frictional heat energy and friction noise, also can prevent that by the sealing of end cap dust from entering with oil leakage simultaneously, during due to running, between axle core and bearing, do not produce heat energy, structure also prevents self evaporating and loss of oil, reaches long-life object.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
Fig. 1 is exploded view of the present invention;
Fig. 2 is the installation diagram of this practical axle core and bearing;
Fig. 3 is the structural drawing of bearing.
In figure: 1 housing, 2 flabellums, 3 bearing supports, 4 bearings, 5 axle cores, 6 Oil Guides are built pressure groove, 7 end caps.
Embodiment
Shown in Fig. 1,2 and 3, long-life type LED cooling fan of the present invention, comprise housing 1, flabellum 2, on housing 1, be provided with bearing support 3, bearing 4 is installed on bearing support 3, flabellum 2 is arranged on bearing 4 by axle core 5, is provided with Oil Guide builds pressure groove 6 at the inwall of bearing 4, seals by end cap 7 at the two ends of bearing 4.In the present embodiment, Oil Guide is built and is pressed groove 6 for man type groove, and Oil Guide is built the two ends up and down of pressing groove 6 to be positioned at bearing 4 inwalls; The internal diameter of bearing 4 intermediate sections is greater than and Oil Guide is set builds and press the internal diameter of groove 6 positions.
The present invention builds pressure groove 6 by special Oil Guide is set at bearing 4 inwalls, when fan running, between axle core 5 and bearing 4, produce a kind of oil film pressure, pressure is built in generation, and axle core 5 and bearing 4 are kept apart completely, does not contact, thereby make it not produce frictional heat energy and friction noise, in the center-side sealing of end cap 7, prevent that dust from entering with oil leakage, during due to running, between axle core 5 and bearing 4, do not produce heat energy, structure also can prevent self evaporating and loss of oil, reaches long-life object.
Product of the present invention has special wind guiding structure and mounting structure in use, prevents that wind from refluxing, and has strengthened air output, thereby has strengthened the radiating effect of LED lamp, reaches and strengthens the LED lamp effect in working life.And between selecting, the torque force of motor and air quantity find a rational equinoctial point, under the radiating effect prerequisite that does not affect LED lamp, strengthen the torque force of product, thereby product can be used in worse environment, strengthened its working life and adaptive capacity to environment.
The above is the preferred embodiment of the present invention; certainly can not limit with this interest field of the present invention; should be understood that; for those skilled in the art; technological scheme of the present invention is modified or is equal to replacement, do not depart from the protection domain of technical solution of the present invention.
