Abstract
The utility model relates to a rotor structure of a motor of an external rotor fan. When the existing fans are in high-speed running, rotor structures are easy to deform and loose by axial force and radial force generated because of high air resistance acting on wind wheels, and the integral reliability of the fans are influenced. The rotor structure comprises a rotor shell, wherein a rotary shaft is arranged at the center of the rotor shell, and a wind wheel is mounted on the outside of the rotor shell. The rotor structure is characterized in that one end of the rotary shaft is connected with a support which is riveted on the rotor shell. The upper portion and the lower portion of the support are riveted with the rotor shell via rivets which are axially consistent with the rotary shaft. Under action of the rivets, durable and stable tension force is kept between the rotor shell and the support, thereby guaranteeing reliability, integral structural stability of the fan after running for a long time and preventing parts of the fan from deforming and loosening.
Description
Technical field
The utility model belongs to the partial structurtes of outer rotor blower fan to be improved, and is specifically related to a kind of outer rotor blower fan motor rotor construction.
Background technology
Rotor case in the existing outer rotor blower fan motor and supporting mass adopt one-body molded usually, and modes such as friction welding, Buchholz protection welding process.When blower fan when running up because wind wheel is subjected to the powerful resistance of air, the axial force of generation and radial load make phenomenons such as rotor structure deforms, becomes flexible easily, influence the blower fan global reliability, and above-mentioned processing mode troublesome poeration, processing cost is higher.
The utility model content
The utility model provides a kind of processing technology simple at the defective of the rotor structure existence of existing outer rotor blower fan motor, and production cost is lower, and rotor remains reliable and stable outer rotor blower fan motor rotor construction.
For this reason, the utility model is taked following technical scheme: a kind of outer rotor blower fan motor rotor construction, comprise that the center is equipped with the rotor case of rotating shaft, wind wheel is installed in the outside of rotor case, it is characterized in that the supporting mass that the end and of described rotating shaft is riveted on the rotor case joins.
The upper and lower part of described supporting mass is by riveting with axially consistent rivet and the rotor case of rotating shaft.
The beneficial effects of the utility model are embodied in: utilize rotor case and supporting mass to adopt rivet to be connected and fixed, under the rivet effect, keep lasting and stable pulling force between rotor case and the supporting mass, guarantee that reliability, the overall structure of blower fan when long-term operation is stable, parts are not yielding, loosening.Riveting process is comparatively ripe, and the equipment of employing is common press, and the buying of rivet parts has reduced production cost easily, guarantees the consistency of product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 rotor case, 2 rotating shafts, 3 rivets, 4 supporting masses, 5 wind wheels, 6 stator bearing-surfaces.
Embodiment
Below in conjunction with specification drawings and specific embodiments substantive distinguishing features of the present invention is further described.
As shown in Figure 1, a kind of outer rotor blower fan motor rotor construction comprises rotor case 1, its outside wind wheel 5 of installing, and inside center is installed rotating shaft 2, and an end of this rotating shaft 2 joins by a supporting mass 7 that is riveted on the rotor case 4.The upper and lower part of supporting mass 7 is by riveting with rotor case 1 with the axially consistent rivet 3 of rotating shaft 2.
The utility model manufacturing process is as follows: require to finish by punch press or press the drawing and forming of rotor case 1 according to drawing, finish the making of supporting mass 4 again.Countershaft 2 is put suitable allowance with stator bearing-surface 6, rotor case 1 is connected by rivet 3 with supporting mass 4, outer surface and supporting mass 4 inner surfaces to rotor case 1 carry out disposable processing again, guarantee both axialities, be pressed into rotating shaft 2 again, be pressed into wind wheel 5 at last, promptly finish the processing of a fan rotor.
Claims (2)
