Abstract
The utility model discloses a high strength low noise centrifugation fan blade, including the rim plate, be provided with first blading and second blading by a plurality of blades on the both ends face of rim plate respectively, what blade and rim plate were connected one serves and has the thickening boss, the other end of blade is connected on circle form strengthening rib. The utility model discloses a set up the thickening boss at blade end for the joint strength of blade end and rim plate is higher, and the performance that the blade held the flexural square is stronger, and the problem of avoiding blade and rim plate connecting portion fracturing rupture to appear that can be better and the other end of blade is provided with circle form strengthening rib, makes each blade be linked to be one, and blade intensity and rigidity are better, and resistant high warm deformation and atress morphotropism can further improves, and the blade -Offset in its first blading and the second blading for the atmospheric pressure pulsation that two sets of blades produced is inconsistent, thereby can weaken the noise stack that two sets of blades produced, and noise resistance can be better.
Description
Technical field
The utility model relates to a kind of fan part, in particular to a kind of centrifugation blade.
Background technology
Centrifugation blade is made up of wheel disc and the some blades being fixed on wheel disc. In prior art, the centrifugation blade being made of plastics, its wheel disc and blade integrated injection molding, low cost of manufacture, production efficiency height. But the centrifugation blade being made of plastics, its intensity is poor, and after particularly working under the different situations such as high temperature, low temperature, distortion easily occurs in its blade, and dynamic balance is deteriorated, the problems such as noise increase.
Practical novel content
In view of this, the purpose of this utility model is to provide a kind of high strength with low noise centrifugation blade, to solve the technical problems such as centrifugation blade intensity difference in prior art, noise are big.
The present embodiment high strength with low noise centrifugation blade, comprise wheel disc, the both ends of the surface of described wheel disc are respectively arranged with the first vane group being made up of some blades and the 2nd vane group, having thickening boss on one end that described blade is connected with wheel disc, the other end of described blade is connected on circle shape stiffening web.
Further, it is separately fixed on two concentric circle shape stiffening webs inside the end of described blade He outside end.
Further, the blade in described first vane group and the blade in the 2nd vane group misplace layout in a circumferential direction.
Further, the inner side edge edge of described blade is provided with zig-zag groove.
Further, the middle part of described wheel disc is provided with round boss, and described round boss is embedded with metal axle sleeve, and the axis hole of described metal axle sleeve is waist-shaped hole.
The beneficial effects of the utility model:
1, the utility model high strength with low noise centrifugation blade, it is by arranging thickening boss at blade tip, make the strength of joint of blade tip and wheel disc higher, the performance that blade bears moment of flexure is stronger, can better avoid blade and wheel disc connection section that the problem of crack fracture occurs, and the other end of blade is provided with circle shape stiffening web so that each blade is linked to be one, blade strength and rigidity are better, and high temperature resistant distortion and its deformation performance improve further.
2, the blade dislocation in the utility model high strength with low noise centrifugation blade, its first vane group and the 2nd vane group is arranged so that the pressure pulsations of two groups of blade generations is inconsistent, it is thus possible to weaken the noise superposition that two groups of blades produce, anti-acoustic capability is better.
3, the utility model high strength with low noise centrifugation blade, it is by arranging zig-zag groove in blade edge, and the big eddy current that blade surface produces can be separated into some little eddy current by zig-zag groove, and the noise that little eddy current produces is lower, it is faster that noise slackens speed, and anti-acoustic capability is better.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment high strength with low noise centrifugation blade, comprise wheel disc 1, the both ends of the surface of described wheel disc are respectively arranged with the first vane group being made up of some blades 2 and the 2nd vane group, having on one end that described blade is connected with wheel disc and thicken boss 3, the other end of described blade is connected on circle shape stiffening web 4.
The present embodiment high strength with low noise centrifugation blade, it is by arranging thickening boss at blade tip, make the strength of joint of blade tip and wheel disc higher, the performance that blade bears moment of flexure is stronger, can better avoid blade and wheel disc connection section that the problem of crack fracture occurs, and the other end of blade is provided with circle shape stiffening web so that each blade is linked to be one, blade strength and rigidity are better, and high temperature resistant distortion and its deformation performance improve further.
As the improvement to the present embodiment, it is separately fixed on two concentric circle shape stiffening webs 4 inside the end of described blade He outside end, adopts two circle shape stiffening webs to make the rigidity of blade better, high temperature resistant and stress deformation is less.
As the improvement to the present embodiment, blade in described first vane group and the blade 2 in the 2nd vane group misplace layout in a circumferential direction, this pressure pulsations that two groups of blades are produced is inconsistent, it is thus possible to weaken the noise superposition that two groups of blades produce, anti-acoustic capability is better.
As the improvement to the present embodiment, the inner side edge edge of described blade being provided with zig-zag groove 5, the noise that little eddy current produces is lower, and it is faster that noise slackens speed, and anti-acoustic capability is better.
As the improvement to the present embodiment, in described blade, be provided with metal core board 6, the rigidity of blade can be improved by arranging metal core board further, distortion that it is high temperature resistant and by power sex change performance stronger.
As the improvement to the present embodiment, the middle part of described wheel disc is provided with round boss 7, described round boss is embedded with metal axle sleeve 8, the axis hole of described metal axle sleeve is waist-shaped hole 9, and this improvement is connected by the axle of metal axle sleeve and blower fan, and the intensity of metal axle sleeve is higher, life-span is longer, and adopting waist-shaped hole to be connected with axle, dynamic balance is good, can reduce the vibration & noise of centrifugation blade.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to better embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, and not departing from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
