Abstract
The utility model discloses an improved axial flow fan which comprises a support and a motor. The motor is of a structure with an outer rotor and an inner stator, the stator is fixedly mounted on the support, the rotor is arranged on the stator in rotating and sleeved modes, fan blades are mounted on the outer surface of the rotor, and the rotor and the stator are provided with a rotor winding and a stator winding respectively. The stator is hollow, and the two ends of the stator are communicated with outside air, the windings are both arranged between the rotor and the stator, a bearing is arranged between the rotor and the stator in a sleeved mode, a positioning clamping spring is arranged on the inner side of the bearing, a sealing ring is arranged on the outer side of the bearing, and the sealing ring is in interference fit with the stator and the rotor. According to the improved axial flow fan, the stator is arranged to be hollow, the two ends of the stator are kept to be communicated with the outside air, the air is made to flow in the stator, heat generated by the motor is taken away, the entire weight of the fan is lowered, the heat radiation performance of the fan is enhanced, and the service life is prolonged. A positioning clamp spring can prevent the rotor winding from moving, and also limit the bearing. The sealing ring is in interference with the stator and the rotor, and dust and impurities are effectively prevented from entering.
Description
Technical field
The utility model relates to a kind of blower fan, particularly a kind of improved axial-flow blower.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure.The mechanical energy of rotating by handle is converted to gas pressure energy and kinetic energy, and a kind of machinery that gas is transferred out.And the height of the size of the power consumption of blower fan, efficiency is the focus that the user pays close attention to always.Traditional blower fan generally has that weight is large, poor radiation, sealing are poor, the shortcoming that working life is short.
The model utility content
The utility model has overcome above-mentioned the deficiencies in the prior art, provide after a kind of improve lightweight, thermal diffusivity good, sealing is strong, the axial-flow blower of long service life.
The technical solution of the utility model is achieved in that
A kind of improved axial-flow blower, comprise bearing, motor, described motor is external rotor inner stator structure, stator is fixedly mounted on bearing, the rotor rotating sleeve is located on stator, at rotor outer surface, fan blade is installed, at rotor, be respectively equipped with the rotor winding on stator, staor winding, stator hollow and two ends communicate with ambient air, the rotor winding, staor winding all is arranged in the space between rotor and stator, be arranged with two bearings between rotor and stator, be provided with the location jump ring in the bearing inboard, be provided with seal ring in the bearing outside, described seal ring and stator, the rotor interference fit.
Adopted working principle of the present utility model and the beneficial effect of technique scheme to be:
Axial-flow blower of the present utility model adopts external rotor inner stator structure, and the bearing side between stator rotor is provided with the location jump ring, both can prevent that the rotor winding from moving, and can carry out spacing to bearing again; In the bearing arranged outside seal ring, seal ring and stator, rotor interference fit, can effectively prevent that dust impurity from entering; The most important thing is, two ends and ambient air that the utility model stator is set to hollow and hollow keep connecting, and air can be flowed in stator, the heat that motor is produced is taken away, both reduce the overall weight of blower fan, strengthened again its thermal diffusivity, extended working life.
The accompanying drawing explanation
The cross sectional representation that Fig. 1 is the utility model blower fan;
Embodiment
