Abstract

The utility model relates to the field of fans, in particular to a motor side-rotating fan, and is mainly applied to cooling of a motor. The motor side-rotating fan comprises a fan shell, a fan cavity is arranged in the fan shell, and a support is mounted on the edge of the fan cavity. Blades and an electric connecting device are in series connection sequentially along the center axis of the support, and are positioned in the fan cavity. A blade ring is sleeved on the blades. The inner side face of the blade ring is fixedly connected with the blades, and the outer side face of the blade ring is abutted against two rubber wheels. The rubber wheels are in friction transmission with the blade ring, positioned on a motor shaft and driven by the motor shaft. The motor side-rotating fan has the advantages of power saving and high power application efficiency.

Description

A kind of motor limit rotary fan
Technical field
The utility model belongs to fan art, mainly applies to the heat radiation of motor, is specifically related to a kind of motor limit rotary fan.
Background technique
Motor ventilating fan is a kind of device for heat radiation, and traditional motor ventilating fan is the power source driving rotating shaft, and rotating shaft drives the blade that is positioned in the rotating shaft again, traditional blade driving mode power consumption, and the power operation efficiency is not high.In view of this, the inventor invents a kind of motor limit rotary fan, and this case produces thus.
Summary of the invention
The purpose of this utility model is to provide a kind of motor limit rotary fan, energy saving more.
In order to reach above-mentioned purpose, the technical solution of the utility model is: a kind of motor limit rotary fan, comprise fan drum, be provided with a fan chamber in the fan drum, the fan chamber edge is equipped with a support, be in series with blade and power on unit successively along the carriage center axle, described blade and power on unit are positioned at fan chamber, be arranged with a blade ring on the described blade, the inner side surface of blade ring is fixedlyed connected with blade, and the outer side surface butt of blade ring has two rubber wheels, and this rubber wheel friction driving is in the blade ring, described rubber wheel is positioned on the motor shaft, and is driven by motor shaft.
The utility model further arranges: described support is A-frame; Described two rubber wheels 180 degree of being separated by arrange.
Driving mode of the present utility model is: motor shaft drives rubber wheel, the rotation of rubber wheel drives the rotation of blade ring, because the blade ring is to fixedly connected with blade, the rotation of blade ring drives the rotation of blade simultaneously, driving mode power saving of the present utility model, and power operation efficiency height.
Below in conjunction with drawings and the specific embodiments the utility model is done and to be described in further detail.
Description of drawings
Fig. 1 is the utility model structural representation.
Specific embodiment
As shown in Figure 1, what the utility model disclosed is a kind of motor limit rotary fan, it comprises fan drum 1, be provided with a fan chamber 2 in the fan drum 1, fan chamber 2 edge are equipped with A-frame 3, be in series with blade 4 and power on unit 5 successively along A-frame 3 central shafts, described blade 4 and power on unit 5 are positioned at fan chamber 2, be arranged with a blade ring 6 on the described blade 4, the inner side surface of blade ring 6 is fixedlyed connected with blade 4, the outer side surface butt of blade ring 6 has two rubber wheels 7, and these rubber wheel 7 friction driving are in blade ring 6, and described rubber wheel 7 is positioned on the motor shaft 8, and by motor shaft 8 drivings, described two rubber wheels 7 180 degree of being separated by arrange, and it is big that more traditional blade 4 pitch of position, the limit pitch of the utility model blade 4 are wanted, and can make motor limit rotary fan produce bigger wind-force.
Driving mode of the present utility model is: motor shaft 8 drives rubber wheel 7, and the rotation of rubber wheel 7 drives the rotation of blade ring 6, because blade ring 6 is to fixedly connected with blade 4, the rotation of blade ring drives the rotation of blade 4 simultaneously.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
