Abstract
The utility model discloses a rotor structure. The rotor structure includes a rotor and a fan blade. The fan blade is assembled at one end of the rotor; the fan blade comprise a connecting end and a working end; the connecting end is connected with one end of the rotor; a plurality of blades are uniformly distributed on the working end; the rotor is a die-casted piece; and the fan blade is an injection-molded piece. According to the rotor structure of the utility model, the rotor is machined through die-casting; no fan blade is required to be installed on an end ring; molds are simple; and therefore, the rotor structure is convenient to manufacture. The fan blade is machined through injection molding separately, so the size of the fan blade is no longer limited by die casting technique; the fan blade enables strong wind, which further enables excellent heat dissipation; and the fan blade is difficult to be damaged. The rotor structure is advantageous in high production efficiency and low cost; and the rotor can be assembled with the fan blade through just one times of riveting, and therefore, the rotor structure is further advantageous in simple technique as well as simple and reliable assembly.
Description
Technical field
The utility model relates to field of motor manufacturing, particularly relates to a kind of rotor structure.
Background technology
Single-phase asynchronous motor is widely used in various electric tools, kitchen articles, various occasions such as household electrical appliance; Rotor is requisite parts in the motor, electric energy is converted into an execution unit of mechanical energy.
The single-phase asynchronous motor rotor is in operation process, and the induced electricity on it fails to be convened for lack of a quorum makes how this heat is dissipated rotor heating, is to do the problem that electric machine structure when design should important consideration.General design is a part that fan blade directly is designed to rotor end ring, and this blade structure is less, and it is relatively poor to dispel the heat, and rotor is damage easily in circular flow; The structure that also has is that fan blade directly is fixed on above the rotating shaft, at this moment need add some location structures (such as flat filament, jump ring groove) in rotating shaft in order to assemble reliably, influences the intensity of rotating shaft like this, thereby influences the quality of motor.
The utility model content
The technical problem that the utility model mainly solves provides a kind of rotor structure, rotor and fan blade can be divided to be arranged, and assembling is simple, is easy to make.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of rotor structure is provided, comprise: rotor, fan blade, described fan blade is assemblied in described rotor one end, described fan blade comprises link, working end, and described link is connected with described rotor one end, evenly is laid with a plurality of blades on the working end, described rotor is die casting, and described fan blade is moulding.
In preferred embodiment of the utility model, described fan blade and rotor are the concentric setting.
In preferred embodiment of the utility model, described link is provided with a plurality of connecting holes, and rotor one end of corresponding described connecting hole is provided with a plurality of connection cylinders.
In preferred embodiment of the utility model, be connected by the riveted joint assembling between described fan blade and the rotor.
The beneficial effects of the utility model are: the utility model rotor structure rotor adopts die-casting process, need not fan blade on the end ring, and mould is simple, is convenient to make; Fan blade is separated by injection moulding processing, and size no longer is subjected to the restriction of extrusion process, and wind-force is big, and good heat dissipation is not fragile in the circular flow; The production efficiency height, cost is low; Rotor and fan blade assembling only need once riveted joint namely to finish assembling, and technology is simple, assembles simple and reliable.

The mark of each parts is as follows in the accompanying drawing: 1, rotor, 2, fan blade, 3, blade, 4, connecting hole, 5, connect cylinder.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises:
A kind of rotor structure comprises: rotor 1, fan blade 2, and described fan blade 2 concentrics are assemblied in described rotor 1 one ends, and the utility model preferably adopts the mode of riveted joint assembling, and technology is simple, and assembling is reliable.
Described rotor 1 is die casting, need not fan blade 2 on the end ring, and mould is simple, is convenient to make.
Described fan blade 2 is moulding, the production efficiency height, and cost is low.
Described fan blade 2 comprises link, working end, and described link is connected with described rotor 1 one ends, evenly is laid with a plurality of blades 3 on the working end.
Described link is provided with a plurality of connecting holes 4, and rotor 1 one ends of corresponding described connecting hole 4 are provided with a plurality of connection cylinders 5.Connecting hole 4 is connected with being connected cylinder 5, and realization rotor 1 is connected with fan blade 2.Assembly structure is simple, is easy to make.
The utility model rotor structure rotor 1 adopts die-casting process, need not fan blade 2 on the end ring, and mould is simple, is convenient to make; Fan blade 2 is separated by injection moulding processing, and size no longer is subjected to the restriction of extrusion process, and wind-force is big, and good heat dissipation is not fragile in the circular flow; The production efficiency height, cost is low; Rotor 1 only needs once riveted joint namely to finish assembling with fan blade 2 assemblings, and technology is simple, assembles simple and reliable.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
