Reduction, so as to reduce vibration and noise.Monocline slot structure being used existing rotor, this monocline slot structure is relatively easy more,
Technique is easily controlled, but is also easy to produce axial float, in the application scenarios such as existing precision machine tool, automobile, this electricity
The use of machine is subject to certain restrictions.
Utility model content
The utility model there is provided a kind of single-bevel groove cast aluminium of low noise exactly in view of the deficienciess of the prior art, turn
Son, to be avoided that axial float, eliminates vibration and noise, so as to improve the dynamic balance performance of rotor.
To reach above-mentioned utility model purpose, the utility model is adopted the following technical scheme that：
A kind of single-bevel groove cast-aluminum rotor of low noise of the utility model, including：Rotor punching and aluminum casting, the rotor punching
Multiple hole slots are provided with piece, and hole slot is distributed uniformly and circumferentially；It is characterized in that, the hole slot is that opening is small broad in the middle
Ampuliform, and it is evenly arranged with insulating barrier in the hole slot.
The characteristics of single-bevel groove cast-aluminum rotor described in the utility model, lies also in, the insulating barrier be marble slab or
Ceramic wafer.
The banking stop of projection is provided with the end face of the rotor punching both sides, and banking stop is higher than the aluminum casting
Highly.
Locating slot is additionally provided with the centre of the rotor punching.
Compared with prior art, the beneficial effects of the utility model are embodied in：
The utility model cast-aluminum rotor, using single-bevel groove cast aluminium, its is simple in construction, and technique is easily controllable, projection it is spacing
Piece not only can be for cooling, while being easy to subsequent technique to increase counterweight, the hole slot of uniform intervals distribution is small broad in the middle for opening
Ampuliform, improve the dynamic balance performance of rotor, eliminate vibration and noise.The reasonable in design, by actual verification with
Use, implementation result is good.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
In the present embodiment, as shown in figure 1, a kind of single-bevel groove cast-aluminum rotor of low noise includes：Rotor punching 11 and cast aluminium
Multiple hole slots 13 are provided with part 12, rotor punching 11, aluminium is from hole slot 13 is through rotor punching 11 and forms aluminum casting 12, cast aluminium
Part 12 is since the end face of rotor punching 11 and through rotor punching 11, rotor punching 11 and the one entirety knot of formation of aluminum casting 12
Structure.
As shown in Fig. 2 the banking stop 14 of projection is additionally provided with the end face of the both sides of rotor punching 11, and banking stop 14 is high
In the height of aluminum casting 12, banking stop 14 is spacing for will be separated between adjacent multiple aluminum castings 12, and when the rotor is turning,
Banking stop 14 can accelerate air flow, be cooled to rotor；Moreover, can be in projection in addition when installing rotor
Banking stop 14 on increase counterweight, improve the dynamic balance performance of rotor.
In specific implementation, as shown in figure 3,20~30 hole slots 13 are provided with rotor punching 11, and hole slot 13 is circumferentially
Direction is uniformly distributed, and hole slot 13 is the small ampuliform broad in the middle of opening, as shown in figure 4, so improving the dynamic balance performance of rotor, is disappeared
Except vibration and noise.Locating slot 15 is additionally provided with the centre of rotor punching 11, multiple accumulations of rotor punching 11 are superimposed upon one
Rise, rely on the realization of locating slot 15 and be accurately positioned, the same dynamic balance performance for improving rotor eliminates vibration and noise.
As shown in figure 5, the cast-aluminum rotor in the present embodiment, can also be uniformly arranged insulating barrier 16, absolutely in hole slot 13
Edge dividing plate 16 is marble slab or ceramic wafer, by setting insulating barrier 16 in hole slot 13, so as to reduce hole slot 13
Width, according to Ampère circuital theoremLearn, under conditions of rotor current is constant, by shortening r so that magnetic induction is strong
Degree is improved, so that electromagnetic torque increased, lifting motor efficiency.
Insulating barrier 16 is marble slab or ceramic wafer, be because marble, ceramics are good insulating materials, its
In marmorean 825 DEG C of fusing point, fusing point of the fusing point than aluminium of ceramics in 825 DEG C or so, ceramic fusing point at 3000 DEG C or so, greatly
In the fusing point (660 DEG C or so) of aluminium, during cast aluminium, the phenomenon that will not be melted.Meanwhile, marble, ceramics possess
Good intensity, with the effect strengthened, supported.
