Abstract
The invention relates to an axial-flow wind wheel, comprising more than two blades (1), a wind wheel support (2) and a shaft sleeve (3), wherein the wind wheel support (2) is sleeved on the shaft sleeve (3), and the blades (1) take the shaft sleeve as a rotary center to be uniformly distributed and are riveted on the wind wheel support. The axial-flow wind wheel is characterized in that the front edge part (4) and/or the outer edge part (5) and/or the tail edge part (6) and/or the blade tip part (7) of each blade (1) are provided with reinforcing ribs (8). In the invention, as the blades are provided with the reinforcing ribs, the strength of the blades of the wind wheel is improved, the wind wheel is more stable in running, vibration caused by imbalance of the wind wheel and pressure fluctuation of the blades is reduced, fatigue fracture of the blades of the wind wheel is avoided, the safety of an air-conditioning system is increased, meanwhile vibration noises are reduced. In addition, the cost of the whole wind wheel is not increased.
Description
Technical field
The present invention relates to a kind of axial-flow windwheel, particularly a kind of axial-flow windwheel that is used for air conditioner outdoor machine belongs to the improvement technology of the axial-flow windwheel that is used for air conditioner outdoor machine.
Background technique
Axial-flow windwheel extensively applies in the air conditioner outdoor machine because air quantity is big, noise is low, pressure is low, and especially the curved use of plunderring axial-flow windwheel of metal is more extensive.The advantage of metal axial-flow windwheel is easy moulding, die cost is low, the height of fan blade can be according to the usage requirement adjustment, shortcoming is the blade easy deformation of wind wheel, each blades height is wayward, causes the imbalance of wind wheel easily, causes whole air conditioner vibration bigger during the wind wheel operation, long-play can cause wind wheel blade and stent fatigue fracture, endangers bigger; In addition, axial-flow windwheel is in running, blade does work to gas, also is subjected to the reaction force of gas, and the rotating speed of wind wheel is high more, reaction force is big more, if the insufficient strength of blade, the variable height of whole wind wheel is bigger, and the pressure of blade surface is different, be easy to generate pressure pulsation, the vibrating noise of whole blower fan is bigger.
At present, some producers strengthen the intensity of blade by the thickness that increases blade material, but the also corresponding increase of the cost of wind wheel has also increased the load of motor simultaneously, and power of fan is also increased; Reduce the tip segment of blade or blade is done quadrangularly, so also can improve the intensity of blade, and reduce the vibrating noise that blade produces owing to pressure pulsation, but the eddy current noise of blower fan increases thereupon, therefore, above scheme all can not effectively be dealt with problems.
Summary of the invention
The objective of the invention is to consider the problems referred to above and provide a kind of cost low, vibrate little, the axial-flow windwheel that noise is low.
Technological scheme of the present invention is: a kind of axial-flow windwheel, comprise two with upper blade, wind wheel support and axle sleeve, the wind wheel support casing is contained on the axle sleeve, blade evenly distributes with the rotating center of axle sleeve and is riveted on the wind wheel support, it is characterized in that the leading edge portion of described blade and/or peripheral edge portion and/or trailing edge part and/or tip segment are provided with stiffening rib.
The external diameter of described wind wheel is D, 50mm＜D＜1500mm.
Distance between the edge of described stiffening rib and blade inlet edge part is S1,0.001＜S1/D＜0.5.
Distance between the edge of described stiffening rib and blade tip part is S2,0.001＜S2/D＜0.5.
Distance between the edge of described stiffening rib and blade peripheral edge portion is S3,0.001＜S3/D＜0.5.
Distance between the edge of described stiffening rib and blade trailing edge part is S4,0.001＜S4/D＜0.5.
Described blade, wind wheel support and axle sleeve all use metallic material to be made.
Described axial-flow windwheel is contained in the outdoor unit of air conditioner.
The present invention is owing to adopt the structure that stiffening rib is set on blade, therefore, improved the intensity of wind wheel blade, more stable when making the wind wheel operation, reduced uneven and blade pressure pulsation-induced vibration because of wind wheel, avoid the wind wheel blade fatigue fracture, improved the Security of air-conditioning system, simultaneously reduced vibrating noise, in addition, the cost of whole wind wheel can not increase yet yet.
