Abstract
A low-cost axial-flow type ventilation fan belongs to the technical field of fans and is designed for the purpose of saving material cost. The low-cost axial-flow type ventilation fan comprises a hub shell (1), an electric motor (2) is fixedly installed inside the hub shell, and an air blast blade is fixedly mounted on a rotating shaft of the electric motor. The low-cost axial-flow type ventilation fan is characterized in that the hub shell (1) is assembled by hub shell piece parts (11) which are divided radially. At the overlapping-joint position of the hub shell piece parts (11), the inner edge is flat and the outer edge is protruded so that reinforcing ribs are formed. Intermediate connecting parts are fixedly installed on the reinforcing ribs and the electric motor so that fixed installation of the electric motor (2) and the hub shell (1) is achieved. The intermediate connecting parts are divided into two groups which respectively correspond to the front portion and the rear portion of the electric motor. Each group of the intermediate connecting parts is provided with four connecting rods (3). Both ends of the connecting rods (3) are respectively fixedly connected to the hub shell (1) and the electric motor (2). The air blast blade is farther away from an air outlet than the electric motor (2). The hub shell is made of sheet molding compound (SMC) materials.
Description
Affiliated technical field
The utility model belongs to pump and blower fan technical field, relates in particular to axial fan.
Background technique
My notification number of application is that CN201554674U, application number are " axial fan of new structure " patent of 200920237666.3, and it comprises a hub shell, is fixed with motor in the hub shell, and airblast blade is packed on the motor rotary shaft; Described hub shell comprises motor mounting section and the wind outlet section that can disassemble each other.Under the production model of compression molding, there be wall thickness big than manual production in it, thereby has strengthened the defective of cost of material; Moreover, though its hub shell is divided into two sections vertically, more original techniques save the space of packed and transported, reducing aspect the packed and transported space, yet exist and continue the leeway optimized.
Summary of the invention
The utility model provides a kind of axial fan cheaply, and it is conservation comparatively, also more saves the packed and transported space.
The technological scheme of the utility model is: the hub shell is radially divided, divided prefabricated hub shell sheet part by this.Become the hub shell by client's assembly unit hub shell sheet part, (through middle union piece) installs motor in the hub shell, and airblast blade is installed.That is:
A kind of axial fan cheaply comprises a hub shell, is fixed with motor in the hub shell, and airblast blade is packed on the motor rotary shaft; It is characterized in that: the hub shell is made up of the hub shell sheet part assembly unit of radially dividing; The mutual lap-joint of hub shell sheet part, its inner rim smooth (not recessed) and its outer rim are protruding, form the strengthening rib of hub shell; There is middle union piece to be installed in strengthening rib and motor, and realizes installing of motor and hub shell.
And the material of hub shell is SMC (Sheet Molding Compound, a sheet unsaturated polyester die plastic) material.
The beneficial effect of the utility model: can know that by said structure the utility model is more saved the packed and transported cost than existing technology; Simultaneously, there are strengthening rib and motor to be installed in the hub shell on its hub shell, then can under the prerequisite that guarantees mechanism's intensity and service life of equipment, reduce the wall thickness of hub shell, reach the purpose that reduces cost of material in the strengthening rib place.Simultaneously, because the scale of construction of part reduces, also can reduce the investment of mould.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is embodiment's a schematic representation.
Fig. 2 is embodiment's a decomposing schematic representation.
Embodiment
As shown in the figure, a kind of axial fan cheaply comprises a hub shell 1, is fixed with motor 2 in the hub shell, and the airblast blade (not shown) is packed on the motor rotary shaft; It is characterized in that: hub shell 1 is made up of hub shell sheet part 11 assembly units of radially dividing; The mutual lap-joint of hub shell sheet part 11, its inner rim smooth (not recessed) and its outer rim are protruding, form the strengthening rib of hub shell; There is middle union piece to be installed in strengthening rib and motor, and realizes installing of motor 2 and hub shell 1.
As shown in the figure, middle union piece is divided into two groups, corresponds respectively to the front portion and the afterbody of motor.In illustrated embodiment, every group of middle union piece has four connecting rods 3, and the two ends of connecting rod 3 (with screw) respectively are connected in hub shell 1 and motor 2.
Middle union piece also can have other form, such as, middle union piece is arc connecting rod; The middle part of this arc connecting rod and motor 2 are connected, and its two ends are connected in the strengthening rib of hub shell 1.Again such as, middle union piece is arc sheet material; The middle part of this arc sheet material and motor 2 are connected, and its both side edges partly is connected in the strengthening rib of hub shell 1.
The material of hub shell is (but be not limited to be) SMC (Sheet Molding Compound, sheet unsaturated polyester die plastic) material.Also can be glass fibre reinforced plastics.
In embodiment, the flow direction of wind is to blow to motor 2 from airblast blade.Be airblast blade than motor 2 away from exhaust outlet.This structure makes the installing space of motor be compounded among the diversion space of wind, can reduce the axial dimension of the utility model whereby, also can strengthen the heat radiation of motor simultaneously.
