Abstract
The utility model discloses a kind of axial flow fan vane wheel for high efficiency motor, comprise wheel hub and blade, wheel hub is hollow structure, and front-end face is entity, and ear end face is empty, and front-end face has positioning hole, in order to connect and supporting motor; The front-end face of wheel hub has large scale fillet.There is a protruding structure strengthening intensity each blade intermediate portion bottom blade root, has a stiffening rib to add jail at the connection part of wheel hub and blade.There is one section of tooth-shape structure at the trailing edge position of every a slice blade, the initial position of tooth-shape structure in about 1/5 leaf eminence of blade, final position at blade close to leaf top place.The beneficial effects of the utility model are: the front-end face of wheel hub has large scale fillet, to reduce gas-flow resistance.Protruding structure and the stiffening rib of strengthening intensity make strength and stability be improved, and the trailing edge position of every a slice blade has one section of tooth-shape structure to make impeller adiabatic efficiency high, and noise is low.
Description
Technical field
The utility model relates to a kind of axial flow fan vane wheel, and more specifically, it relates to a kind of axial flow fan vane wheel for high efficiency motor.
Background technique
External rotor axial-flow fan is widely used in ventilation refrigerating field with its good performance, energy-conserving and environment-protective are Main way for world industry development, efficient energy-saving fan is also the developing direction of present outer rotor blower fan, two large main bodys of blower fan comprise motor and fan blade two large divisions, so while exploitation motor, the main body-fan blade as converting wind energy also awaits design optimization.
Summary of the invention
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of rational in infrastructure, effectively prevent the Multifunction dustless driven blackboard of dust harzard.
The purpose of this utility model is achieved through the following technical solutions.This axial flow fan vane wheel for high efficiency motor, comprises wheel hub and blade, and described wheel hub is hollow structure, and wall thickness is 2 ~ 6mm, and front-end face is entity, and ear end face is empty, and front-end face has for connecting the positioning hole with necessary electromotor, in order to connect and supporting motor; The front-end face of wheel hub has fillet.There is a protruding structure strengthening intensity described each blade intermediate portion bottom blade root, has a stiffening rib to add jail at the connection part of wheel hub and blade.There is one section of tooth-shape structure at the trailing edge position of every a slice blade, the initial position of tooth-shape structure in about 1/5 leaf eminence of blade, final position at blade close to leaf top place.
As preferably: the size B ≈ C ≈ 3A of each little tooth of described tooth-shape structure, profile of tooth is formed by streamlined arc transition, and the value of described B is between 3 ~ 8mm.
As preferably: described tooth-shape structure from the initial position of little tooth to final position, described little tooth or etc. size be uniformly distributed, or etc. size become thin gradually, or little tooth is uniformly distributed gradually from large to small, or little tooth becomes gradually from large to small and dredges.
As preferably: described wheel hub and blade are injection molded by plastic mould, also can be made of one piece by metallic material punching stretch.
The beneficial effects of the utility model are: the front-end face of wheel hub has large scale fillet, to reduce gas-flow resistance.There is a protruding structure strengthening intensity described each blade intermediate portion bottom blade root, has a stiffening rib to add jail at the connection part of wheel hub and blade.Strength and stability is improved, and the trailing edge position of every a slice blade has one section of tooth-shape structure to make impeller adiabatic efficiency high, and noise is low.
Accompanying drawing explanation
Fig. 1 is axial flow fan vane wheel schematic diagram described in the utility model;
Fig. 2 is blade shape and dimensioned drawing.
Description of reference numerals: wheel hub 1, blade 2, positioning hole 3, axis hole 4, protruding structure 5, tooth-shape structure 6, stiffening rib 7.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, modified model and equivalent.
As shown in Figure 1 to Figure 2, the wheel hub 1 of the present embodiment is hollow structure, and wall thickness is 2 ~ 6mm, and front-end face is entity, and ear end face is empty, and front-end face has four positioning holes 3, in order to the high efficiency motor connected and the utility model is supporting.The front-end face of wheel hub 1 has large scale fillet, to reduce gas-flow resistance.
There is a protruding structure 5 strengthening intensity each blade 2 intermediate portion bottom blade root, has a stiffening rib 7 to add jail at the connection part of wheel hub 1 and blade 2, is formed and strengthens structure in length and breadth.And there is one section of tooth-shape structure 6 at the trailing edge position of every a slice blade 2, the initial position of tooth-shape structure 6 in about 1/5 leaf eminence of blade 2, final position at blade 2 close to leaf top place.The shape and size of each little tooth are as shown in Figure 2: B ≈ C ≈ 3A, profile of tooth is formed by streamlined arc transition, and according to different fan blade sizes, the value of B is between 3 ~ 8mm.From the initial position of little tooth to final position, little tooth or etc. size be uniformly distributed, or etc. size become thin gradually, or little tooth is uniformly distributed gradually from large to small, or little tooth becomes gradually from large to small and dredges.
Wheel hub 1 and several blades 2 are by metal stretching or plastics injection moulding integrated molding.Positioning hole 3 is connected with the joint of supporting high efficiency motor, and in order to fixing impeller, the projecting shaft of axis hole 4 and high efficiency motor coordinates card jail, in order to transferring power.
