Abstract
The utility model relates to an air impeller for an electric machine, which is formed by stamping sheet metal. The middle of the air impeller for the electric machine is a circular boss, wherein, the center of which is provided with an axle hole, and the periphery of the circular boss is provided with shaped blades of an air impeller. The utility model is characterized in that the air impeller for the electric machine is provided, the air impeller for the electric machine is low in cost and convenient in processing technology, product quality and production efficiency can be enhanced, and vibration and noise of the impeller are decreased. The utility model has the advantages of easy installation and convenient maintenance.
Description
The utility model relates to manufacturing, the especially manufacturing of washing machine motor fan blade of motor blower fan wheel.
The fan blade of existing motor for washer is to pass through the die casting moulding by die casting aluminium, makes the V-shaped groove of fan blade reach the size and the precision of drawing regulation through cut again.Its shortcoming is that the process-cycle is longer, and raw materials consumption is big, the cost height, and consistency of product is relatively poor.Owing to adopt radial screw to fix between fan blade and the motor shaft, caused off-centre, the vibration and the noise of motor there is certain influence.
The purpose of this utility model is: provide a kind of and can reduce cost, simplify the motor blower fan wheel of technology, and can improve the quality and the production efficiency of fan blade, reduce the vibration and the noise of impeller, installation, maintenance is convenient.
The purpose of this utility model is achieved in that a kind of motor blower fan wheel, it is characterized in that being stamped to form by sheet metal, and its central authorities extrude round boss, and the center has axis hole, is provided with the fan blade blade of moulding at the edge.
Improvement of the present utility model is: be processed into the motor blower fan wheel by a square plate, in peripheral 4 the angle correspondences of square thin plate.Cut respectively along diagonal from 4 angles of square thin plate, and cut a vertical deep-slotted chip breaker.2 ends at the above-mentioned deep-slotted chip breaker at each angle bend square thin plate periphery respectively from deep-slotted chip breaker to the thin plate edge, form 2 blades vertical with thin plate.
Characteristics of the present utility model are: provide cost low; Processing technology is the motor blower fan wheel easily, and can improve product quality and production efficiency, and reduces the vibration and the noise of impeller, and installation, maintenance is convenient.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is a chip architecture schematic diagram on the utility model,
Fig. 2 is a chip architecture schematic diagram under the utility model,
Fig. 3 is the installation diagram of the utility model and motor,
Fig. 4 is for making plane outspread drawing of the present utility model.
As shown in the figure, the utility model divides upper and lower 2, be stamped to form by sheet metal respectively, last slice can also be a packing ring, another embodiment last slice as shown in Figure 1, a circular sheet, there is a round boss centre, (this boss plane is exactly a upper and lower installed surface) has a flat round hole 8 in boss 9 central authorities.This circular sheet outwards has a tapering from the boss edge, the flange of (with the boss opposite direction) is arranged upwards in the outer most edge of circular sheet.Following sheet as shown in Figure 2, a square thin plate, there is a round boss 10 centre, in boss central authorities a flat round hole 8 is arranged.This thin plate outwards has a tapering from the boss edge, a bigger tapering is outwards arranged, the peripheral arc transition of the edge of tapering and above-mentioned square thin plate from the edge of this tapering.Outside square thin plate, place with round boss is concentric and have 4 sections uniform deep-slotted chip breakers 7, corresponding with 4 angles of square thin plate respectively.Cut respectively along diagonal from 4 angles of square thin plate, switch to deep-slotted chip breaker always.2 ends of above-mentioned 4 sections deep-slotted chip breakers respectively with square thin plate periphery from deep-slotted chip breaker this must be downwards to the thin plate edge (with boss in the other direction) 90 ° of bendings, form 8 blades vertical 11 with thin plate.On blade and thin plate, plurality of strengthening ribs is arranged.The angle that another kind of embodiment is blade and thin plate can also be 75-105 °.
Have on 1 in the motor in the diagram one with blade on the oblate boss that is complementary of flat round hole, with lower gasket 3, down sheet 2, last slice 4, upper gasket 5 is inserted in this boss successively, the boss epimere has screw thread, by nut 6 upper and lower of fan blade and motor shaft is fastened as one.
The utility model last slice, following sheet are stamped to form by sheet metal is disposable, the production efficiency height, and good product consistency and precision height, fineness is good, need not following process.Adopt axial nut fastening during installation, without acceptance of persons, reduced the vibration and the noise of motor.
Claims (2)
