Abstract
The utility model discloses a supporting base for an axial flow fan. The supporting base comprises an outer frame, a central ring is arranged in the middle of the outer frame, a ventilation opening corresponding to auxiliary blades is formed in the central ring, a plurality of supporting ribs connected with the outer frame are arranged on the periphery of the central ring in an outward radiation mode, and ventilation ducts corresponding to main blades are formed between the supporting ribs. The supporting base comprises the outer frame, the outer frame is used for installing and fixing the fan, the central ring is arranged in the middle of the outer frame, the ventilation opening corresponding to the auxiliary blades is formed in the central ring, the supporting ribs connected with the outer frame are arranged on the periphery of the central ring in the outward radiation mode, and the ventilation ducts corresponding to the main blades are formed between the supporting ribs. A rotor rotates, air draught flows through the ventilation ducts under the effect of the main blades and flows through the ventilation opening under the effect of the auxiliary blades, and the supporting base enables the fan to be fixed and also enables ventilation to be almost unimpeded.
Description
Technical field
The utility model relates to a kind of axial-flow blower, particularly a kind of bearing for axial-flow blower.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure.The mechanical energy of rotating by handle is converted to gas pressure energy and kinetic energy, and a kind of machinery that gas is transferred out.And the height of the size of the power consumption of blower fan, efficiency is the focus that the user pays close attention to always.Traditional blower fan generally has that power consumption is high, efficiency is low, the easy overheated short shortcoming of service life of fan that causes of motor.
A kind of axial-flow blower of special preliminary imagination design, this axial-flow blower stator hollow and both ends open and ambient air keep being formed through an interior ventilation flue; Be provided with main blade and secondary fan blade on rotor, main blade is fixedly installed on the outer surface of rotor, and an end and the rotor of secondary fan blade are fixedly linked, and the other end of secondary fan blade extends to the aperture position place of stator one end; Stator hollow, reduced the weight of axial-flow blower, energy saving; The rotor running can drive main blade and turn round together with secondary fan blade, and air draught flows from rotor and in stator, has improved the efficiency of axial-flow blower, and takes away the heat that the axial-flow blower running produces, the working life of having improved axial-flow blower.And axial-flow blower can not directly be used, need to install and fix, just seem particularly important so design one with its bearing that can mate use.
The model utility content
The utility model has overcome above-mentioned the deficiencies in the prior art, a kind of bearing for axial-flow blower is provided, this bearing has not only played the fixedly effect of blower fan of installing, can also with the coordinating of the main blade of blower fan, secondary fan blade, intimate expedite ventilation is provided.
The technical solution of the utility model is achieved in that
A kind of bearing for axial-flow blower, described bearing comprises housing, at the middle part of housing, is provided with center ring, forms the ventilated port corresponding with secondary fan blade in center ring, a plurality of supporting ribs that are connected with housing are arranged along the center ring periphery to external radiation, form the ventilation flue corresponding with main blade between supporting rib.
Adopted working principle of the present utility model and the beneficial effect of technique scheme to be:
Bearing of the present utility model comprises housing, housing is for installing fixedly blower fan, middle part at housing is provided with center ring, form the ventilated port corresponding with secondary fan blade in center ring, a plurality of supporting ribs that are connected with housing are arranged along the center ring periphery to external radiation, form the ventilation flue corresponding with main blade between supporting rib.The rotor running, air draught flows through from ventilation flue under the effect of main blade, under the effect of secondary fan blade, from ventilated port, flows through, and this bearing has not only played the fixedly effect of blower fan, can also provide and be close to expedite ventilation.
The accompanying drawing explanation
The structural representation that Fig. 1 is bearing in embodiment;
The use phase diagram that Fig. 2 is bearing.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: a kind of bearing for axial-flow blower, as shown in Figure 1, 2, described bearing comprises housing 1, be provided with center ring 2 at the middle part of housing 1, the ventilated port 6 that the interior formation of center ring 2 is corresponding with secondary fan blade, a plurality of supporting ribs 7 that are connected with housing 1 are arranged along center ring 2 peripheries to external radiation, form the ventilation flue 8 corresponding with main blade between supporting rib 7.
As shown in Figure 2, during installation, stator 3 is arranged on the housing 1 of bearing, the corresponding secondary fan blade 5 of the ventilated port of center ring 2 and interior ventilation flue 22, the corresponding main blade 33 of the ventilation flue between supporting rib 7.
Claims (1)
1. the bearing for axial-flow blower, it is characterized in that: described bearing comprises housing, middle part at housing is provided with center ring, form the ventilated port corresponding with secondary fan blade in center ring, a plurality of supporting ribs that are connected with housing are arranged along the center ring periphery to external radiation, form the ventilation flue corresponding with main blade between supporting rib.
