Abstract
A vane wheel of fan comprises a hub with a plurality of blades, an annular groove arranged on the hub and grooves on the blades; wherein, the annular groove are communicated with the grooves; the hub and the blades are connected into a hole. A mounting hole is also arranged on the hub. With the structure and compared with the prior art, the utility model strengthens rigidity, reduces the weight of the blades and at the same lowers driving power of electromotor and noise.
Description
(1) technical field
The utility model relates to a kind of ventilating fan impeller.
(2) background technique
The ventilating fan impeller is the revolving part of ventilating fan, and the centrifugal force during rotation is bigger, and it comprises wheel hub and blade on it is set, be that sheetmetal more than the 1mm is stamped to form generally by thickness, its weight is big, needs supporting powerful motor, has the big defective of vibration in addition.
(3) summary of the invention
The purpose of this utility model is to provide a kind of overall performance good, and the ventilating fan impeller that rigidity is strong is to overcome the deficiency of prior art.
The utility model is achieved in that a kind of ventilating fan impeller, comprises the wheel hub that is provided with a plurality of blades, and wheel hub is provided with circular groove, and blade is provided with groove.
Circular groove is connected with groove, and wheel hub becomes a body with blade, be provided with mounting hole on wheel hub, the sectional shape semicircular in shape or the half elliptic of circular groove and groove.
After adopting said structure, owing on wheel hub and blade, be respectively equipped with circular groove and groove, and circular groove is connected with groove, increased rigidity, compared with prior art, the impeller of same shape and size, can adopt thickness to be stamped to form less than the sheetmetal below the 1mm, when running up, still can keep better balance performance, alleviate the weight of impeller simultaneously, also reduce motor driving power and noise.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the plan view of Fig. 1.
(5) embodiment
As shown in Figure 1, 2, 3, a kind of ventilating fan impeller through after improving comprises the wheel hub 1 that is provided with four blades 2.During manufacturing, be processed with circular groove 1-1 on the wheel hub 1, be processed with groove 2-1 on the blade 2, and circular groove 1-1 is connected with groove 2-1.In the present embodiment, wheel hub 1 and blade 2 are stamped to form a body by sheetmetal, also have mounting hole 1-2 on wheel hub 1, so that coupling is installed and is linked with motor shaft.The sectional shape semicircular in shape of circular groove 1-1 and groove 2-1 also can become half elliptic.The utility model also can be the engineering plastics moulding.
