Abstract
The utility model discloses a fan with an inner rotor motor matched with an outer rotor impeller. The fan comprises the motor and the impeller, wherein the motor comprises a motor casing, a fixing ring, a fixing groove and a rotating shaft; the impeller comprises blades and a bearing bush; a driving device of the motor is located in the motor casing, is connected with the rotating shaft and can drive the rotating shaft to move; the bearing bush of the impeller is provided with a groove and a bulge which are matched with the fixing ring and the fixing groove of the motor, so that the motor and the impeller can be matched closely and firmly. The fan has the benefits as follows: the groove and the bulge which are matched with the fixing ring and the fixing groove are arranged on the bearing bush, so that the motor and the impeller are combined closely and firmly, the coaxiality of the rotating shaft and the impeller is improved, and the fan is lower in noise and more energy-saving.
Description
Technical field
The utility model relates to a kind of device of driven by motor wind wheel, and particularly a kind of inner rotor motor is joined external rotor fan impeller.
Background technique
In the production and design of motor and blower fan, there is the difference of internal rotor and external rotor.Wherein, for motor, rotor runs up with electric machine main shaft one, and electric machine stand is fixedly inner rotor motor; Rotor is along with motor housing rotates together, and what electric machine main shaft was fixing is " external rotor " motor.The general number of poles of internal rotor is few, and rotating speed is high, and torque is little; The general number of poles of external rotor is many, and rotating speed is low, and torque is large.
And for blower fan, impeller is along with electric machine main shaft one runs up, electric machine stand is fixed, Here it is " internal rotor " blower fan; Blower fan-matched " external rotor " motor, draught fan impeller is along with motor housing rotates together, and electric machine main shaft is fixed, Here it is " external rotor " blower fan.
In prior art for the ease of the connection of motor and wind wheel, all generally that inner rotor motor is joined internal rotor impeller or external rotor electric machine is joined external rotor impeller, under this Placement easily there are vibrations wearing and tearing in the coaxality of machine shaft and wind wheel in running, cause wind wheel amplitude of fluctuation large, cause thus noise large and not energy-conservation.
Model utility content
The utility model is in order to address the above problem, and the utility model provides a kind of construction of stable, easy-to-use solution.
To achieve these goals, the utility model provides following technological scheme:
Inner rotor motor is joined an external rotor fan impeller, comprises internal rotor inner rotor motor 1, and wherein motor comprises again motor housing 11, retainer ring 12, fixed groove 13, rotatingshaft 14; External rotor outer rotor 2, comprising blade 21, bearing housing 22.The inside that the drive unit of inner rotor motor 1 is positioned at motor housing 11 is connected with rotatingshaft 14, can drive the motion of rotatingshaft 14, realizes in motor and turning; On the bearing housing 22 of outer rotor 2, have and the retainer ring 12 of inner rotor motor 1, groove and projection that fixed groove 13 matches, make inner rotor motor 1 and outer rotor 2 after installation, form firmly cooperation, and realize the outer of wind wheel and turn.
As preferably, Leaf positional distribution is in the outside of wind wheel and be uniformly distributed along bearing housing 22 centers.
As preferably, the quantity of blade is even number and symmetrical.
As preferably, the quantity of blade is 6 and symmetrical.
As preferably, the height of retainer ring 12 is not less than 1/4th of rotatingshaft 14.
The beneficial effects of the utility model are, by the groove and projection that arrange on bearing housing 22 and retainer ring 12, fixed groove 13 match, realize the close and firm combination of internal rotor inner rotor motor 1 and external rotor outer rotor 2, improve rotating shaft and the coaxality of wind wheel in running, less noise and more energy-conservation.
accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the structural representation of this inner rotor motor;
Fig. 2 is the structural representation of external rotor outer rotor;
Comprising internal rotor inner rotor motor 1, motor comprises again motor housing 11, retainer ring 12, fixed groove 13, rotatingshaft 14; External rotor outer rotor 2, wherein comprises again blade 21, bearing housing 22.
embodiment
The inside that the drive unit of inner rotor motor 1 is positioned at motor housing 11 is connected with rotatingshaft 14, can drive the motion of rotatingshaft 14; On the bearing housing 22 of outer rotor 2, have and the retainer ring 12 of inner rotor motor 1, groove and the projection that fixed groove 13 matches, inner rotor motor 1 and outer rotor 2 can be realized firmly after installation to be coordinated, on outer rotor 2, be provided with 8 symmetrical blades, when this mechanism moves, due to motor and wind wheel link close and firm, the coaxality of rotating shaft and wind wheel is high, and noise is little and more energy-conservation.
Above-mentioned example is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the utility model Spirit Essence or modification, within all should being encompassed in protection domain of the present utility model.
