Description
Technical field
The utility model relates to the dc brushless motor technical field, is specifically related to a kind of two formula dc brushless motor rotor that is connected.
Background technology
Tradition dc brushless motor rotor comprises rotor core, magnet steel etc., and according to the difference of permanent magnet position on rotor, rotor structure generally is divided into two kinds: surface-type and built-in.Surface-type: in this structure, permanent magnet is tile shape usually, and be positioned on the cylindrical outer surface of rotor core, and generally only overlap non-magnetic cylinder between the circle in permanent magnet outer surface and the stator core to shield, or make protective layer with no latitude glass tape at permanent magnetism magnetic pole surface bag; This type non-magnetic cylinder difficulty of processing is big, cost is high, manufacturability is poor, unfavorable batch generates; The technology of no latitude band of boning is loaded down with trivial details, also can not come off and reduces motor gas-gap and influence motor rotation generation noise if motor temperature has the latitude band when surpassing the heatproof temperature of no latitude band.Built-in: the permanent magnet of this class formation is positioned at internal rotor, the pole shoe that (externally rotor magnetic circuit mechanism is then between permanent magnet inner surface and the rotor core cylindrical) has ferromagnetic material to make between the circle in permanent magnet outer surface and the stator core, can place cast aluminium cage or copper bar cage in the pole shoe, rise damping or (with) priming; Utilize design, the difficulty of processing of this mode rotor core big, the relative surface-mount type of glue line can approach a lot, also adhesive glue can be pushed out a part when therefore magnet steel being inserted built-in groove, adhesive glue can not be utilized fully like this, perhaps magnet steel is fixed, like this complex process with embedding bonded adhesives or epoxy resin.Reliable in structure but leakage field is very big, efficient is low.In case the too high adhesive glue of electric machine temperature rise can be ineffective, magnet steel can come off.
The utility model content
In view of this, the utility model provides a kind of two formula dc brushless motor rotor that is connected, by using adhesive glue, also further using compression bar that magnet steel is fixed on the rotor core, adopt this pair formula that is connected to realize being fastenedly connected of magnet steel and rotor core, the course of processing is simple, and is workable.
A kind of two formula dc brushless motor rotor that is connected comprises compression bar, magnet steel and rotor core; Wherein, have groove on the rotor core cylindrical outer surface; Compression bar is "T"-shaped, and the two ends of inboard, outer are the inclined-plane; Magnet steel is non-concentrically ringed tile, and the left and right sides is outer inclined-plane and matches with inclined-plane on the compression bar; Magnet steel is fixed on the cylindrical of rotor core in the form of a ring by adhesive glue; Compression bar is between every adjacent two magnet steel, and its inboard boss is embedded in the groove of rotor core, and the outer inclined-plane on the inclined-plane at two ends and the magnet steel matches, and is fixed on the rotor core.
Beneficial effect:
According to above technical scheme as seen, use the two formulas that are connected of the utility model magnet steel is fixed on the rotor core, viscous force by adhesive glue and compression bar can guarantee that to the pressure of magnet steel magnet steel is securely fixed on the rotor core, the course of processing is simple, and is workable.
Secondly, compression bar of the present invention adopts aluminum strip, and its thermal conductivity is good, in light weight, cost performance is high.

Embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, the utility model is described in detail.
As shown in Figure 1, the two formula dc brushless motor rotors that are connected of the utility model comprise the tight bar of jewelling, magnet steel and rotor core.Have on the rotor core cylindrical outer surface around the equally distributed groove of circumference.Shown in Fig. 2, it is "T"-shaped compressing aluminum strip, and the two ends of inboard, outer are the inclined-plane, and its inboard boss can be embedded in the groove of rotor core just fully.As shown in Figure 3, magnet steel is non-concentrically ringed tile shape, and the left and right sides is outer inclined-plane and matches with the inclined-plane that compresses on the aluminum strip; Wherein, the number of groove, compression bar and magnet steel equates to be respectively 2
nIndividual.
Magnet steel is bonded in the form of a ring by adhesive glue on the cylindrical outer surface of rotor core, and the thickness of adhesive glue is 1～2mm.Compress aluminum strip between every adjacent two magnet steel, its T type boss is embedded in the groove of rotor core, and compresses the inboard boss of aluminum strip and rotor core bottom portion of groove gap is 0.1-0.3mm; Have screw hole on the compression bar, compression bar is fastened on the rotor core,, can increase steel-wire screw-socket and lock trip bolt again if rotor core is a punching formula structure by the sticking anaerobic adhesive of trip bolt.Wherein match, and further magnet steel is connected on the rotor core by the outer inclined-plane on inclined-plane on the compression bar and the magnet steel.
The fit dimension and the required precision of the utility model apparent surface formula structure compression bar and magnet steel are low, work good and get final product in the inclined-plane that only needs to compress two inclined-planes of aluminum strip and magnet steel during assembling.
In sum, more than be preferred embodiment of the present utility model only, be not to be used to limit protection range of the present utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
