Abstract
The utility model discloses a kind of big bearing rotor rotary electric machine of stabilization, including axle, small bearing and rotor, described axle sleeve is on small bearing, and described internal rotor passes through small bearing coupling spindle, it is characterised in that：The periphery of described rotor is enclosed on big bearing, and described small bearing is provided with two, and the two ends end to end of socked shaft are distinguished in the inside of two small bearings.Described big bearing is located at the head of rotor.The two ends of described rotor couple the periphery of two small bearings respectively.Of the present utility model simple in construction, external rotor electric machine is rotated by the anastomosis of small bearing around axle, again by increasing big bearing on the head of rotor, stability when rotor is rotated is improved, it is ensured that concentricity when working rotor, while extending service life of the motor to bearing.
Description
Technical field
The utility model is related to external rotor electric machine, and the big bearing rotor rotary electric machine of especially a kind of stabilization belongs to technology
Field.
Background technology
When motor drives the rotation of outer rotor (i.e. outer steel) assembly, separation sleeve band is passed through by the effect magnetic line of force in magnetic field
Dynamic internal rotor (magnet steel in i.e.) assembly and impeller synchronous rotary, medium is completely enclosed within static separation sleeve, so as to reach nothing
The purpose of medium is pumped in leakage.
Often function is relatively simple for our model plane external rotor electric machine at present, usually has rotor in use in addition and is turning
It is eccentric to surrounding non-directional when dynamic, it is very inconvenient；Traditional external rotor electric machine, rotor eccentricity carries out the same of rotor
The heart and stability are a nothing the matters.
Utility model content
The purpose of this utility model is that there is provided a kind of stabilization rational in infrastructure in order to solve the defect of above-mentioned prior art
Big bearing rotor rotary electric machine.
The purpose of this utility model can be reached by adopting the following technical scheme that：
A kind of big bearing rotor rotary electric machine of stabilization, including axle, small bearing and rotor, described axle sleeve is in small bearing
On, described internal rotor passes through small bearing coupling spindle, it is characterised in that：The periphery of described rotor is enclosed on big bearing, institute
The small bearing stated is provided with two, and the two ends end to end of socked shaft are distinguished in the inside of two small bearings.
As a kind of preferred scheme, described big bearing is located at the head of rotor.
As a kind of preferred scheme, the two ends of described rotor couple the periphery of two small bearings respectively.
Of the present utility model simple in construction, external rotor electric machine is rotated, then lead to by the anastomosis of small bearing around axle
Crossing the head in rotor increases big bearing, improves stability when rotor is rotated, it is ensured that concentricity when working rotor, together
Service life of the Shi Yanchang motors to bearing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1- axles, the big bearings of 2-, the small bearings of 3-, 4- rotors.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, a kind of big bearing rotor rotary electric machine of stabilization is further elaborated.It should be appreciated that described herein specific
Embodiment only to explain the utility model, is not used to limit the utility model.
Embodiment 1：
As shown in figure 1, a kind of big bearing rotor rotary electric machine of stabilization of the present embodiment, including axle 1, small bearing 3 and turn
Son 4, being enclosed on small bearing 3 for described axle 1, passes through the small coupling spindle 1 of bearing 3 inside described rotor 4, it is characterised in that：Institute
The periphery for the rotor 4 stated is enclosed on big bearing 2, and described small bearing 3 is provided with two, and the inside of two small bearing 3 is socketed respectively
The two ends end to end of axle 1.
As shown in figure 1, described big bearing 2 is located at the head of rotor 4.
As shown in figure 1, the two ends of described rotor 4 couple the periphery of two small bearing 3 respectively.
Of the present utility model simple in construction, external rotor electric machine is rotated by the anastomosis of small bearing 3 around axle 1, then
Pass through increases big bearing 2 on the head of rotor 4, improves stability when rotor 4 is rotated, it is ensured that the operation of rotor 4 it is same
Heart degree, while extending service life of the motor to bearing.
It is described above, only the utility model patent preferred embodiment, but the utility model patent protection domain simultaneously
This is not limited to, any one skilled in the art is in the scope disclosed in the utility model patent, according to this
Technical scheme and its utility model patent design of utility model patent are subject to equivalent substitution or change, belong to the utility model
The protection domain of patent.
