Abstract
The utility model discloses a heat radiation fan, which comprises a seat body, a PCB base plate, a lower insulating rack, an upper insulating rack, a stator, a coil, an axial core, a bearing and a fan blade, wherein, the lower part of the outer frame of the seat body is provided with a clamping position for installing the bearing, the upper part of the bearing is provided with a shoulder position on the installing position point of the stator, the inner circle point of the stator is provided with a reinforcing rib towards the direction of the bearing, and the upper part of the outer frame of the seat body corresponding to the position of the reinforcing rib is provided with a groove. The groove is tightly matched with the reinforcing rib which is extended to the shoulder position, the inner circle point of the upper insulating rack is also provided with a reinforcing rib towards the direction of the axial core, and the installing position of the reinforcing rib corresponds to the reinforcing rib of the stator and can tightly press the reinforcing rib of the stator. The utility model can effectively avoid the core extrusion contraction of the bearing, the different sound and the speed reduction which are caused by the core extrusion contraction of the bearing can be eliminated, the bearing can be repeatedly used after repairing and disassembling, and the cost can be saved.
Description
Technical field
The utility model relates to a kind of radiation fan.
Background technique
Existing radiation fan, its stator center is a circular hole, four smaller part circular ports again distribute around the interior circle, and the internal diameter circle of the external diameter of pedestal central stator mounting point circle and stator is a drive fit, being close to cooperation is installed in stator on the pedestal, and bearing is pressed into pedestal and needs drive fit, and need come off in case cooperate too loose by certain pressure.Because bearing is by the copper powder metallurgy die cast, the core that easily contracts after being subjected to ambient pressure causes different sound and rotating speed on the low side, brings unfavorable factor for the quality of processing assembling.In addition, after defective products was overhauled, bearing can not re-use because of being subjected to extruding, caused the wasting of resources.
The model utility content
The purpose of this utility model is to provide a kind of heat sinking fan, and this radiation fan has overcome the copper bearing core that contracts because of being squeezed and caused different sound, and it is reusable to overhaul back copper bearing.
A kind of radiation fan that the utility model provides comprises pedestal, PCB substrate, following insulating frame, goes up insulating frame, stator, coil, axle core, bearing, flabellum.Described flabellum is contained on the core, and the axle core is positioned at the center of bearing, and bearing is located in the housing of pedestal, and stator is positioned at the housing top of pedestal, and upper and lower insulating frame is positioned at the upper and lower both sides of stator, and coil is respectively on upper and lower insulating frame; Described pedestal housing bottom is provided with a screens that is used to lay bearing, the top of bearing is provided with a shoulder position at the stator installed position, the inner circle of stator is provided with stiffening rib to the bearing direction, the housing top of pedestal is provided with groove corresponding to the position of stiffening rib, groove and stiffening rib drive fit, and stiffening rib extends to the shoulder position; The described inner circle of going up insulating frame also is provided with stiffening rib to shaft core direction, and the stiffening rib that position and stator are set of this stiffening rib is corresponding and press the stiffening rib of stator.
Stiffening rib described in the utility model can be provided with many as required, and as a kind of form of the present utility model, the stiffening rib that is provided with on described stator and the last insulating frame is respectively four, and four stiffening ribs are five equilibrium and arrange.
The present external frame bottom of the utility model is provided with a screens, and bearing is unclasped in the housing and can not come off from outer frame bottom; The top of bearing is provided with a shoulder position at the stator installed position, extruding when not be pressed into by stator, in addition, stator is to reach stiffening rib and the pedestal housing drive fit that goes up insulating frame by itself, can not come off with the stator drive fit after making both sides be subjected to squeeze, the stiffening rib that stretches out by stator blocks the shoulder position of bearing and can not come off from the flabellum direction more again.Can avoid bearing top circle to be squeezed fully after the assembling of such structure and the core that contracts occur, and bearing be recycling when overhauling.
Compare with existing radiation fan, difference of the present utility model is that the means of fixation of stator is that bearing is to fix by the means of fixation of blocking vertically rather than by fashion of extrusion by drive fit after the extruding of stiffening rib.The utility model can effectively be avoided the crowded compressed core of bearing, eliminates because of bearing different sound and the rotating speed that core causes that contract reduces, and overhauls rear bearing and can also reuse, and has saved cost.
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Embodiment
As shown in Figure 1, 2, the utility model radiation fan comprises pedestal 1, PCB substrate 2, following insulating frame 3, goes up insulating frame 4, stator 5, coil 6, axle core 7, bearing 8, flabellum 9.Fan 9 leaves and be contained on the core 7, axle core 7 is positioned at the center of bearing 8, and bearing 8 is located in the housing 10 of pedestal 1, and stator 5 is positioned at housing 10 tops of pedestal 1, and upper and lower insulating frame is positioned at the upper and lower both sides of stator 5, and coil 6 is respectively on upper and lower insulating frame.Housing 10 bottoms of pedestal 1 are provided with a screens 11 that is used to lay bearing 8, and the top of bearing 8 is provided with four shoulder positions 12 at stator 5 installed positions, and the inner circle of stator 5 is provided with 13, four stiffening ribs 13 of four stiffening ribs to bearing 8 directions and is the five equilibrium arrangement.Housing 10 tops of pedestal 1 are provided with four grooves 14 corresponding to the position of four stiffening ribs 13, groove 14 and stiffening rib 13 drive fits, and stiffening rib 13 extends to shoulder position 12.It is corresponding and press the stiffening rib 13 of stator 5 that the inner circle of last insulating frame 4 also is provided with four stiffening ribs that position and stator 5 are set 13 of 15, four stiffening ribs 15 of four stiffening ribs to axle core 7 directions.
